2014-08-06T14:51:00.000+05:30

In the past decade, MySQL database has become popular, and WordPress blog using a MySQL database, although the use of plug-ins can solve some problems, but to achieve some special tasks, execute SQL statements in phpMyAdmin is the most concise way, here is a useful summary of eight WordPress system SQL statements used to solve some practical problems encountered.

1. create a backup of the database

　　Backup of the database is the first thing to do, just by following a simple method you can back up the database:

　　After login phpMyAdmin. Choose your WordPress database, and then click on the "Export" button, select a compression method (you can use gzip) and click the "Go" button, when the browser when prompted to download, click "Yes", download the file to the database locally.

2. bulk delete articles Amendment

　　WordPress2.6 later version adds a Post revisions feature, though some use, but the article is amended to increase the size of your database, we can choose to bulk delete.

　　After logging in phpMyAdmin execute the following SQL statement to bulk delete.

DELETE FROM wp_posts WHERE post_type = "revision";

3. batch delete spam comments

　　A true story is that one of my friends set up a blog on the Internet, there are times he spent a few days on vacation, no Internet, and when he came back, log in to your blog, saw more than 5000 comments Wait audit, of course, most of them are spam comments to manually delete these comments to spend a lot of time, so we can use the following approach.

　　Execute the following SQL statement after login phpMyAdmin.

DELETE from wp_comments WHERE comment_approved = '0';

　　Be careful, though this solution is useful for processing millions of ordinary garbage, but will remove comments without approval, so it is best to install or use Akismet to fight comment spam.

4. modify article properties

　　After you install WordPress, admin account is created, a lot of people are wrong to use this account to write a blog, until they realize that this is not a personal account.

　　The solution, each article to modify the properties need a lot of time, the following SQL statement can help you quickly complete this function.

　　First you have to find your correct user name, use the following SQL statements can be found in your user ID number.

SELECT ID, display_name FROM wp_users;

　　Assuming that this ID is NEW_AUTHOR_ID, and administrator admin ID for
OLD_AUTHOR_ID, then run the following SQL statement.

UPDATE wp_posts SET post_author = NEW_AUTHOR_ID WHERE post_author = OLD_AUTHOR_ID;

5.Manual Reset Password

　　A lot of people in order to protect their own blog not being hacked, using a very complex password, although this is a good thing, but often forgotten administrator password things will happen.

　　Of course, you can send to your WordPress link to reset your password via e-mail, but if you can not access your e-mail address, then had to use the following SQL statement to reset your password.

UPDATE wp_users SET user_pass = MD5 ('PASSWORD') WHERE wp_users.user_login = 'admin' LIMIT 1;

　　MD5 hash function is a built-in MySQL for converting password hashes.

6.change WordPress domain

　　Sometimes you may want to change your blog's domain name, but WordPress will put your name stored in the database, so you have to use the following SQL statement to modify.

UPDATE wp_options SET option_value = replace (option_value, 'http://www.oldsite.com', 'http://www.newsite.com') WHERE option_name = 'home' OR option_name = 'siteurl';

　　Then, you have to use the following SQL GUID of the article will also be modified.

UPDATE wp_posts SET guid = replace (guid, 'http: //www.oldsite.com','http: //www.newsite.com');

　　Finally, use the following statement will replace the article all the old domain to the new domain name.

UPDATE wp_posts SET post_content = replace (post_content, 'http://www.oldsite.com', 'http://www.newsite.com');

7. showing the number of SQL queries

　　You have something to blog in performance when the number of queries the database learned is very important, in order to reduce database query, we need to know on one page in the end how many queries.

　　This time, do not need to log in phpMyAdmin, you only need to modify the footer.php file, at the end of the file add the following lines of code.

<? PHP if (is_user_logged_in ()) {?>
<? PHP echo get_num_queries ();?> queries in <PHP timer_stop (1);??> seconds.
<PHP?}?>

8.restore your WordPress database

　　When your database for some reason (hacking or upgrade error) is damaged or lost, if you have a backup, then you can restore your WordPress database.

　　Sign in phpMyAdmin, select your WordPress database, click "Import" button, click "Browse" button, then "Run" button to import the database from your hard drive to select the backup file, point.

　　If all goes well, your WordPress functions will return to normal.

Easy Ways to Speed Up Your Android Mobiles in Under 3 Minutes

2013-08-05T07:20:00.003+05:30

1. Clear Your App Cache (30 seconds)

Over time, your programs write to the app cache on your phone and eat up precious system resources while slowing everything down. You can clear the cache on any individual app by visiting its property page in the Settings menu and tapping the clear cache button, but with dozens of apps on most phones, it could take an eternity to do this manually.

App Cache Cleaner, a free app, makes it easy to delete the cache on all your apps at once with just a couple of taps. After installing and launch App Cache Cleaner, simply tap Clear All and you’re done.

Of course, the cache will fill up again over time, and you’ll want to delete it again. App Cache Cleaner has an Auto Clear feature. If you enter its settings menu, tap Auto Clear Interval and select a duration, it will automatically clear the cache on a regular basis. However, this means that the app needs to run in the background.

Installing and using App Cache Cleaner for the first time should take around 30 seconds.

2. Disable or Uninstall Unused Apps (60 seconds)

You may not know it, but many of the apps you never even use may be running in the background, eating up precious system resources. From the app that you tried for 5 minutes last month to the shopping app that came preloaded on your phone, every unused app has the potential to weigh your phone down. It’s easy to uninstall apps you’ve downloaded yourself, but crapware is a little harder to dispose of.
If you have rooted your phone, you can completely remove every trace of your preloaded apps. If not, you can still disable those apps through the settings menu. It should take about 10 seconds to uninstall or disable each app you don’t want. It should take you approximately one minute to get rid of 6 apps, longer if you have more crapware to dump.

3. Install a New App Launcher (30 seconds)

Your phone’s app launcher controls your desktop, lock screen apps menu, and other critical parts of the UI. Though every Android phone comes with its own preloaded app launcher, you can install a third party launcher that will not only change the look and feel of your device, but also speed the time it takes it to navigate around the OS. There are many different launchers available in the app store, but we found Lightning Launcher Home to be among the fastest and easiest to use.
To use Lightning Launcher or another launcher of your choice:

Install Lightning Launcher from the Google Play store.
Tap the Home Button. A menu appears asking you which launcher you want.
Select Lightning Launcher and Tap Always.

Downloading the Lightning Launcher, and setting it to run as your default should take 30 seconds.

4. Remove Unnecessary Widgets and Shortcuts (30 seconds)

Even with a speedy App Launcher installed, your phone will use more memory the more widgets and shortcuts it has in memory. Look through your desktops for widgets you don’t absolutely need and remove them by long pressing and dragging them off screen.

A number of phones with widgets that advertise services such as media stores or news services. Unless you really want to look at a list of hot YouTube videos or Google Play Books on your home screen every day, remove these.
Dragging half a dozen shortcuts and widgets off of your desktops should take 30 seconds.

5. Limit or Disable Background Data (10 to 60 seconds)

Your email, your Gmail, your Facebook, your Twitter and your backup app all want to ping the Internet for data on a regular basis. All that syncing not only eats up your battery, but also takes up system resources and slows your device down.
There are some services you may want to sync in real time, but there are others you can check manually. For example, if you don’t need to be alerted the moment you get a Facebook mention or receive an email to your personal account, you can prevent those from connecting in the background.
To disable background data for all apps:

Navigate to Settings.
Tap Data usage.
Launch the context menu by tapping the three dots in the upper left corner of the screen or hitting the menu button (on Samsung and LG phones).
Toggle Autosync data to off and tap Ok on the warning that comes up.

To disable background data for Gmail, Google+ and other Google Services:

Navigate to Settings. You can get to the Android settings menu from the notification drawer or apps menu.
Tap on Google under accounts.
Tap the account name. If the sync icon next to the account name is green, it has sync permission. If it is gray, syncing is already disabled.
Toggle all types of data syncing to off, including email, contacts and calendar.

To turn off background data in other apps such as Facebook or the standalone email client, you must go directly into their settings’ menus and find the option to never update or update manually. Disabling all your background at once should take just 10 seconds, but if you want to manually disable Gmail, Facebook and email client autosync separately, this process could take as long as a minute.

Depending on how many apps you need to uninstall and services you wish to disable, you could finish speeding up your phone in as little as 2 minutes and 40 seconds. That’s a very small time investment to make your smartphone snappier.

Tutorial for Grub 2 recovery

2013-07-02T02:29:00.005+05:30

Grub 2 recovery

We often come across a condition in which the boot loader gets corrupt. Here are a few steps that will help you recover your GRUB 2 boot loader.
Boot from a live CD or DVD, Which supports GRUB 2 (Ubuntu 9.10 CD or A DVD will take more time than a CD, so I suggest you boot from a CD).
Open the terminal and run fdisk -l to check the partition from which you want to recover GRUB 2.
Here I assume that you want to recover it from /dev/sda1.
Then run the following commands:

$sudo mkdir /media/sda1

$sudo mount /dev/sda1/media/sda1

$sudo mount --bind /dev /media/sda1/dev

$sudo mount --bind /proc /media/sda1/<span class="GINGER_SOFATWARE_mark" ginger_sofatware_uiphraseguid="3fd64c47-30e8-45b0-90b6-3ab942f867b1" id="b1828793-ca2f-49c5-8f00-92c4cb7f51bd">proc</span>

$sudo mkdir /media/sda1

$sudo mount /dev/sda1/media/sda1

$sudo mount --bind /dev /media/sda1/dev

$sudo mount --bind /proc /media/sda1/proc

Now chroot into that partition by running the command given below:

$sudo <span class="GINGER_SOFATWARE_mark" ginger_sofatware_uiphraseguid="abaefe31-ea4a-4ab0-a902-e7cf9c4fbd6c" id="33159db4-100e-4345-af77-845f92da1742">chroot</span> /media/sda1

1

$sudo chroot /media/sda1

Then re-install GRUB , as follows:

#grub-install /dev/sda

1

#grub-install /dev/sda

The output should be like what’s shown below:

<span class="GINGER_SOFATWARE_mark" ginger_sofatware_uiphraseguid="1f08ad5c-ff9d-4645-aa77-e497cf9efa15" id="52b6ae22-225e-44dc-96c4-a1bb52d09f29">Installation</span> finished. No error reported.

1

Installation finished. No error reported.

If you get an error, then try the following command:

#grub-install --recheck /dev/sda

1

#grub-install --recheck /dev/sda

After a successful installation, exit from chroot and unmount the file systems that were mounted to recover GRUB. Now reboot.

#exit $sudo unmount /media/sda1/<span class="GINGER_SOFATWARE_mark" ginger_sofatware_uiphraseguid="f2f91f90-a63c-4c07-b812-8bbf12494017" id="d797a7e8-c80a-495e-976f-0c01077f02e4">proc</span> $sudo unmount /media/sda1/dev $sudo unmount /media/sda1 $sudo reboot

1

6

7

8

9

#exit

$sudo unmount /media/sda1/proc

$sudo unmount /media/sda1/dev

$sudo unmount /media/sda1

$sudo reboot

You’ve successfully completed recovering your boot loader. Try this it will help you for sure. Be careful while doing this and keep the steps in your mind.

Cookies Explanation for Beginners

2013-07-02T02:29:00.003+05:30

cookies

Starting with Netscape 3.0 in 1996, browsers began to offer support for cookie.The following is a quote from the Netscape cookie specification:
A server, when returning an HTTP object to a client, may also send a piece of state information which the client will store. Included in that state object is a description of the range of URLs for which that state is valid. Any future HTTP requests made by the client which fall in that range will include a transmittal of the current value of the state object from the client back to the server.The state object is called a cookie, for no compelling reason.
Cookies provide an invaluable tool for maintaining state between requests. More than just a way of conveying credentials and authorizations, cookies can be effectively used to pass large and arbitrary state information between requests—even after the browser has been shut down and restarted.
Cookies are the de facto standard for transparently passing information with HTTP requests.These are the major benefits of cookies over Basic Authentication:

Versatility—Cookies provide an excellent means for passing around arbitrary information between requests. Basic Authentication is, as its name says, basic.
Persistence—Cookies can be set to remain resident in a user’s browser between sessions. Many sites take advantage of this to enable transparent, or automatic, login based on the cookied information. Clearly this setup has security ramifications, but many sites make the security sacrifice to take advantage of the enhanced usability.
Of course users can set their cookie preferences to refuse cookies from your site. It’s up to you how much effort you want to apply to people who use extremely paranoid cookie policies.
Aesthetic—Basic Authentication is the method that causes a browser to pop up that little username/password window.That window is unbranded and unstyled, and this is unacceptable in many designs.When you use a homegrown method, you have greater flexibility.

The major drawback with using cookie-based authentication is that it does not allow you to easily protect non-PHP pages with them.To allow Apache to read and understand the information in cookies, you need to have an Apache module that can parse and read the cookies. If a Basic Authentication implementation in PHP employees any complex logic at all, you are stuck in a similar situation. So cookies aren’t so limiting after all.

Authentication Handlers Written in PHP
In PHP 5 there is an experimental SAPI called apache_hooks that allows you to author entire Apache modules in PHP. This means that you can implement an Apache-level authentication handler that can apply your authentication logic to all requests, not just PHP pages.
When this is stable, it provides an easy way to seamlessly implement arbitrarily complex authentication logic consistently across all objects on a site.

Easyway to resetting wordpress password using FTP

2013-07-02T02:28:00.000+05:30

Resetting wordpress password using FTP

return $pageURL;

}

This code is a php function which allows you to find out the current page URL.
You can get the Current page URL like this

<<span class="GINGER_SOFATWARE_mark" ginger_sofatware_uiphraseguid="70d456fa-4b67-412f-b875-216af6a71cc1" id="33f0d945-0513-43c2-ae81-57170c869ac8">?</span><span class="GINGER_SOFATWARE_mark" ginger_sofatware_uiphraseguid="70d456fa-4b67-412f-b875-216af6a71cc1" id="0f5e2d18-1d5d-4dba-8c70-db7374d3f5ba">php</span>

?>

<?php

echo curPageURL();

This will print the current page URL. But for this tutorial we need to store it in a variable.

<<span class="GINGER_SOFATWARE_mark" ginger_sofatware_uiphraseguid="9b98ddd6-4394-42cd-99e5-23d4d51e33cb" id="6ced4367-b00f-40e3-8a84-4cad34d989be">?</span><span class="GINGER_SOFATWARE_mark" ginger_sofatware_uiphraseguid="9b98ddd6-4394-42cd-99e5-23d4d51e33cb" id="dd37c43e-0d55-4270-a97f-105248843438">php</span>
  $cur = <span class="GINGER_SOFATWARE_mark" ginger_sofatware_uiphraseguid="b07a5a61-0059-4e5b-97f6-a5cbeed011dc" id="fd0b9cb7-d767-4a50-afbd-3dd13fa76570">curPageURL</span><span class="GINGER_SOFATWARE_mark" ginger_sofatware_uiphraseguid="b07a5a61-0059-4e5b-97f6-a5cbeed011dc" id="4e6e187b-389a-4226-bc3a-7e7c45e42dca">(</span>);
?>

<?php

$cur = curPageURL();

We’ve stored the current page URL in the variable ‘$cur’.

Step 2

Now we need to split the URL according to ‘/’ and have to select the last part.

$parts = Explode<span class="GINGER_SOFATWARE_mark" ginger_sofatware_uiphraseguid="5906276b-a02a-4863-9863-25e86b658673" id="c84083a2-9c00-4e76-bc0b-c967594520eb">(</span>'/', $cur);
$url = $parts<span class="GINGER_SOFATWARE_mark" ginger_sofatware_uiphraseguid="9343b86c-46c5-4a8c-b07c-c70701f086d8" id="44984502-f68f-4b08-9577-097a12cd6774">[</span>count<span class="GINGER_SOFATWARE_mark" ginger_sofatware_uiphraseguid="9343b86c-46c5-4a8c-b07c-c70701f086d8" id="d0488c69-8430-4274-a664-6c2e3cd8c7c3">(</span>$parts) - 1];

1 2	$parts = Explode('/', $cur); $url = $parts[count($parts) - 1];

Note: if your URL is something like this ‘http://www.example.com/pages/about’ you’ve to use the above code as it is, but if your URL is Like this ‘http://www.example.com/pages/about/’ you’ve to change the ‘-1′ to ‘-2′.
The above code will store last part of the URL in the variable $url for example ‘about’.

Step 3

Now all you need to do is save an image in this name. eg. ‘about.jpg’
Then go to your page and put the following code where you want your image to be placed.

<<span class="GINGER_SOFATWARE_mark" ginger_sofatware_uiphraseguid="c31f7438-0b27-4794-a237-955f7a27c2a6" id="e89f04fa-bee4-4820-af94-dffe6d67504d">img</span> src="path/to/image/<?<span class="GINGER_SOFATWARE_mark" ginger_sofatware_uiphraseguid="c31f7438-0b27-4794-a237-955f7a27c2a6" id="cac53041-a105-404a-a3c1-4cc4070660a5">php</span> echo $url; ?><span class="GINGER_SOFATWARE_mark" ginger_sofatware_uiphraseguid="67b1dad3-fdad-4efd-aab9-6bf4716622ca" id="edd1a452-cf78-4ac0-8aac-8b45e040b09d">.</span><span class="GINGER_SOFATWARE_mark" ginger_sofatware_uiphraseguid="67b1dad3-fdad-4efd-aab9-6bf4716622ca" id="2da9f2e1-5ae7-4c08-ab45-4d265079940c">jpg</span>" />

1	<img src="path/to/image/<?php echo $url; ?>.jpg" />

Hurrah!! if you go to that page you can see your image. Now include all the above codes into each page where you want to show the images and place the image with the same name of URL’s last part.

Here is the tutorial for php pdf creation.
For this you need to download a file called fpdf.php

$pdf->Output();

Take a look at the code, First you need to include the fpdf.php file using require() function.
after requiring the library file, we instantiate an object of the FPDF class and call it $pdf.
Then we add a page with the AddPage method, set our output font, define the cell (location) for our string of output, and then—using the Output method—display the PDF in the browser.
Output for the above code will be

Top 20 PHP Tips and Tricks for beginners

2013-06-30T22:29:00.000+05:30

PHP tips to improve PHP skills

Hi people, in this post i’m gonna deliver you some interesting quick tips to explore and improve PHP skills. Try to follow these tips when you code.

Use <?php ... ?> tags for PHP. All other formats are depreciated including short tags.
It is very useful to use Unset or null your variables to free memory, especially for large arrays.
It is better to wrap you strings in single quotes (”) instead of double quotes (“”). Beacuse PHP looks for variables into double quotes.So unless you’re gonna use a variable inside, don’t use doubles quotes for variables.
echo is faster than print. So avoid using ‘print’ often.
“else if” statements are faster than select statements aka case/switch.
Use sprintf instead of using variables contained in double quotes, it is about 10x faster.
Turn on mod_deflate in Apache v2 to reduce the use of bandwidth. For Apache v1 try mod_gzip.
Avoid using string concatenation. Preferred method is echo’s multiple parameters (or stacked).
Avoid using pre-calculated functions in loops. for eg. for($i=0; $i< count($array);$i++) This will call count function each time. So store it in a variable like this $count = count($array); before the loop starts.
Avoid using magic methods like __isset(), __unset(), __sleep().
Avoid require_once() and use require() where possible.
Better to Use full paths in includes and requires.
require() and include() are same in all the ways. One different is require will halt if the file is missing. Performance wise there is a very little difference between them.
Since PHP5, the script execution start time can be found by $_SERVER[’REQUEST_TIME’], so avoid using time() or microtime().
PCRE regex is quicker than EREG, but always look out if you can use quicker native functions such as strncasecmp, strpbrk and stripos instead.
Try xml2array when parsing XML in PHP, which makes use of the PHP XML functions, for HTML you can try PHP’s DOM document or DOM XML in PHP4.
Error suppression with ” @ ” is very slow.
str_replace is faster than preg_replace. str_replace is best overall, however strtr is sometimes quicker with large strings. Using array() inside str_replace is usually quicker than multiple str_replace.
$row[’id’] is 7x faster than $row[id], because if there is no quotes PHP has to guess which index you meant, assuming you didn’t mean a constant.
It is always better to close your database connection after the use.

PHP form handling for beginners

2013-06-30T22:28:00.001+05:30

PHP form handling Tutorial

PHP form handling is the thing which irritates you if you’re a beginner.
The most important thing to notice when dealing with HTML forms and PHP is that any form element in an HTML page will automatically be available to your PHP scripts.

Example

The example below contains an HTML form with two input fields and a submit button:

<<span class="GINGER_SOFATWARE_mark" ginger_sofatware_uiphraseguid="4b62fdc2-fa9f-41a5-860c-5cc0edc27d76" id="28635d31-47cc-4d81-b98c-a7f2d6af6d69">html</span>>
<<span class="GINGER_SOFATWARE_mark" ginger_sofatware_uiphraseguid="48bb2565-4e37-4aa4-8750-b5942ffc95b0" id="8c9f0e7f-60bf-42b3-8920-01cda041499c">body</span>>
<<span class="GINGER_SOFATWARE_mark" ginger_sofatware_uiphraseguid="2a66f25b-9bf9-4746-ba7f-c90ac4ab5582" id="34138ca8-b3a1-4af3-a06d-d9625525d8d9">form</span> action="welcome.php" method="post">
Name: <input type="text" name="<span class="GINGER_SOFATWARE_mark" ginger_sofatware_uiphraseguid="6240520d-1f00-469f-8ecc-1f848e82e9fb" id="8524789a-7650-41cc-8a7c-05e44e7e4537">fname</span>" />
Age: <input type="text" name="age" />

</<span class="GINGER_SOFATWARE_mark" ginger_sofatware_uiphraseguid="e59eadb6-34c6-49bc-9ebe-dea679f6db47" id="989f0ac0-d346-48b5-9bfb-885583773e63">form</span>>

<html>

<body>

Name: <input type="text" name="fname" />

Age: <input type="text" name="age" />

</form>

</body>

</html>

When a user fills out the form above and click on the submit button, the form data is sent to a PHP file,
called “welcome.php“:
“welcome.php” looks like this:

<<span class="GINGER_SOFATWARE_mark" ginger_sofatware_uiphraseguid="d7492025-4dc9-464d-91e8-dcb626ba1e1c" id="ac004bcd-7785-4e3c-ad0b-f316dbc83223">html</span>>

<html>

<body>

Welcome <?php echo $_POST["fname"]; ?>!<br />

You are <?php echo $_POST["age"]; ?> years old.

</body>

</html>

Output could be something like this

Welcome John!

You are 28 years old.

The PHP $_GET and $_POST functions will be explained in the next chapters.

Form Validation

User input should be validated on the browser whenever possible (by client scripts). Browser validation is faster and reduces the server load.
You should consider server validation if the user input will be inserted into a database. A good way to validate a form on the server is to post the form to itself, instead of jumping to a different page. The user will then get the error messages on the same page as the form. This makes it easier to discover the error.
The built-in $_GET function is used to collect values in a form with method=”get”.

The $_GET Function

The built-in $_GET function is used to collect values from a form sent with method=”get”.
Information sent from a form with the GET method is visible to everyone (it will be displayed in the browser’s address bar) and has limits on the amount of information to send (max. 100 characters).

Example

<<span class="GINGER_SOFATWARE_mark" ginger_sofatware_uiphraseguid="edb14116-7e63-4312-91f1-12614d729f1f" id="8622c52a-4b1c-41b5-a02e-03ec2c4ae86f">form</span> action="welcome.php" method="get">

Name: <input type="text" name="fname" />

Age: <input type="text" name="age" />

</form>

When the user clicks the “Submit” button, the URL sent to the server could look something like this:
http://www.voidtricks.com/welcome.php?fname=Peter&age=37
The “welcome.php” file can now use the $_GET function to collect form data (the names of the form fields will automatically be the keys in the $_GET array):

When to use method=”get”?

When using method=”get” in HTML forms, all variable names and values are displayed in the URL.
Note: This method should not be used when sending passwords or other sensitive information!
However, because the variables are displayed in the URL, it is possible to bookmark the page. This can be useful in some cases.
Note: The get method is not suitable for large variable values; the value cannot exceed 100 characters.
The built-in $_POST function is used to collect values in a form with method=”post”

The $_POST Function

The built-in $_POST function is used to collect values from a form sent with method=”post”.
Information sent from a form with the POST method is invisible to others and has no limits on the amount of information to send.
Note: However, there is an 8 Mb max size for the POST method, by default (can be changed by setting the post_max_size in the php.ini file).

Example

<<span class="GINGER_SOFATWARE_mark" ginger_sofatware_uiphraseguid="7cea88d1-5df6-401b-b177-4d5524eb56a6" id="af19071c-8df3-4ea1-8f54-5718126c47c3">form</span> action="welcome.php" method="post">

However, because the variables are not displayed in the URL, it is not possible to bookmark the page.

The PHP $_REQUEST Function

The PHP built-in $_REQUEST function contains the contents of both $_GET, $_POST, and $_COOKIE.
The $_REQUEST function can be used to collect form data sent with both the GET and POST methods.

Paint Colors

You can actually paint colors with color handling methods.

Color Handling

For images with an 8-bit indexed palette it can be tricky to manage colors (paint colors).

Output:

Truecolor

For Truecolor images the colors are actually simple 31-bit longs. Or, think of them as being composed of 4 bytes arranged like this:

The highest or leftmost bit in the alpha channel is not used which means the alpha channel can only have values from 0 to 127. You can use the ImageColorAllocate() as with paletted images, but you can also specify the color directly.

HOW TO INSTALL CHAINFIRE 3D

This is a tutorial on how to install CHAINFIRE 3D pro on your techno N3 Or android phone. And how to use CHAINFIRE 3D run most games on your Android phones using chainfire 3D pro.

WHAT CHAINFIRE 3D DOES?

What Chainfire3D does is that it stands between your apps and the Graphics drivers, and intercept and/or change commands between the two. It has some built-in functions, and can be further extended with plugins To provide extra functions.

Warning:: It is recommended for 1ghz+ devices only and the phone must be rooted to use this app!
It works on Android 2.1 + devices but is safer on Android 2.1 devices!

HOW TO INSTALL CHAINFIRE 3D

Download and install Chainfire3D (disregard warning and device will reboot).
Download it's plugins Plugins or.
Extract the plugins you downloaded to your SD card (they are 3 .i.e.(POWERVR/Qualcomm/Tegra).
Open Chainfire 3D and click on Install plugin/shaders and then, chainfire 3d will search your sd card for plugins.
When it's done searching click on the 3 plugins one by one to install them
Install libGLEMU_POWERVR.zip (for PowerVR), Install libGLEMU_NVIDIA.zip (for Nvidia), Install libGLEMU_QUALCOMM.zip (for Qualcomm).
Go back and click on Default OpenGL settings and select reduce Texture quality then scroll down and click on use plugin and select QUALCOMM.
You can now launch your games.

Chainfire3D has been tested on:
- HTC HD2
- Samsung Galaxy y
- Samsung Galaxy S
- Samsung Galaxy Tab 7"
- Samsung Galaxy S II
- Samsung Epic 4G
- Motorola Atrix 4G
- Motorola Droid 2
- LG Optimus 2X
- Google Nexus S
- Bsnl Penta
- Bsnl Teracam
It would likely work on other devices. So far nobody has reported a failed install XDA FORUM.. This doesn't mean problems can't happen and I will not be responsible Cause you do this at your own risk! If you are a techno N3 or N7 user I Can user it will definitely work for you.

Note:
Use Qualcomm or Nvidia plugin as your default Qualcomm as it is quite powerful and supports almost all games. Use PowerVR plugin for any games or application that need high graphic Performance and better solution i.e under per-App OpenGL Settings. PowerVR plugin is not recommended to be used as a default plugin cause it Will stress your GPU will damage it over time just like ram expansion Does to your memory card.

5 Star Rating System

2013-04-30T09:05:00.000+05:30

In this tutorial, you’ll learn how to build a rating system with AJAX, PHP, and jQuery. Votes will be recorded and updated in real-time with the magic of AJAX, and we’ll also leverage the power of PHP so that you don’t even need a database!

Step 1. Building the HTML

We’re going to create a simple page that lists two movies, and allows you to rate them. This means we need the stars to show the current rating, and to allow voting. We also want an area to show the total votes cast, and the current rating down to one decimal place.

Let’s take a look at the HTML/CSS

view plain copy to clipboard print ?

<div class='movie_choice'>
Rate: Raiders of the Lost Ark
<div id="r1" class="rate_widget">
<div class="star_1 ratings_stars"></div>
<div class="star_2 ratings_stars"></div>
<div class="star_3 ratings_stars"></div>
<div class="star_4 ratings_stars"></div>
<div class="star_5 ratings_stars"></div>
<div class="total_votes">vote data</div>
</div>
</div>
<div class='movie_choice'>
Rate: The Hunt for Red October
<div id="r2" class="rate_widget">
<div class="star_1 ratings_stars"></div>
<div class="star_2 ratings_stars"></div>
<div class="star_3 ratings_stars"></div>
<div class="star_4 ratings_stars"></div>
<div class="star_5 ratings_stars"></div>
<div class="total_votes">vote data</div>
</div>
</div>

Notice how there are no graphics in this HTML? They’ll be added with CSS. We’re just using the HTML to create the framework that the widget works from. Now it’s time to start adding CSS.

view plain copy to clipboard print ?

.rate_widget {
border: 1px solid #CCC;
overflow: visible;
padding: 10px;
position: relative;
width: 180px;
height: 32px;
}
.ratings_stars {
background: url('star_empty.png') no-repeat;
float: left;
height: 28px;
padding: 2px;
width: 32px;
}
.ratings_vote {
background: url('star_full.png') no-repeat;
}
.ratings_over {
background: url('star_highlight.png') no-repeat;
}

This first part of the CSS accomplishes a few things:

Gives the default ‘empty’ start to each star location
Sets up classes for filled in stars, and highlighted stars
Defines and styles the stars’ container.

You can either use the graphics provided in the download, or make your own. There needs to be a graphic for each of the three states: empty, full, and highlighted.
Next we add a little more CSS to position the total votes box, and center the widgets so the page matches the graphic at the start of this section.

.total_votes {
background: #eaeaea;
top: 58px;
left: 0;
padding: 5px;
position: absolute;
}
.movie_choice {
font: 10px verdana, sans-serif;
margin: 0 auto 40px auto;
width: 180px;
}

Step 2. Adding the UI Interactivity

At this point, we have a very plain looking bunch of empty stars, but they don’t do a whole lot at this point. This is where jQuery comes to the rescue.

Our first step is to add mouseover and mouseout handlers for the stars. We need to highlight the star the mouse is over, and all the preceding stars.

view plain copy to clipboard print ?

$('.ratings_stars').hover(
// Handles the mouseover
function() {
$(this).prevAll().andSelf().addClass('ratings_over');
$(this).nextAll().removeClass('ratings_vote');
},
// Handles the mouseout
function() {
$(this).prevAll().andSelf().removeClass('ratings_over');
set_votes($(this).parent());
}
);

We’re taking advantage of jQuery’s powerful .prevAll() and .nextAll() methods to get the stars preceding and following the currently moused over star.
The code above then adds and removes the classes to make the stars under the mouse and before ‘highlighted’, and the stars after ‘not highlighted’.

What about set_votes() ?

This is a function that checks which stars should be in the ‘full’ state, and ties in closely with the next step, where we grab remote data from the server.

Step 3. Retrieving Data from the Server

Our stars highlight when you move the mouse over them, and that’s a great start. But what about the red stars showing the current vote? To reach this step, we need to both get the information from the server, and write some JavaScript to handle that data.

view plain copy to clipboard print ?

$('.rate_widget').each(function(i) {
var widget = this;
var out_data = {
widget_id : $(widget).attr('id'),
fetch: 1
};
$.post(
'ratings.php',
out_data,
function(INFO) {
$(widget).data( 'fsr', INFO );
set_votes(widget);
},
'json'
);
});

This code block – actually all the JavaScript – goes in a document.ready block. This particular code executes right away. It queries the server and gets some information on every vote widget on the page.
First we set up an object, out_data, to contain the information we’re sending to the server. Our PHP script expects to see ‘fetch’ when just grabbing data, so we include it here. We also include the ID of the widget, which lets the server-side script know what data we’re after. When the call back function fires, it contains a JavaScript object that looks like this:

view plain copy to clipboard print ?

{
"widget_id" : "r1",
"number_votes" : 129,
"total_points" : 344,
"dec_avg" : 2.7,
"whole_avg" : 3
}

The .data() method is a bit of jQuery magic that allows you to associate arbitrary data with a DOM
object.

If you look closely at the code, you’ll see we’re taking that object (stored in the variable INFO) and
doing something with it via the .data() method.
The .data() method is a bit of jQuery magic that allows you to associate arbitrary data with a DOM
object. In this case, we’re storing the data in the widget div. It can be accessed later like this:

view plain copy to clipboard print ?

$('#one_of_your_widgets).data('fsr').widget_id;

set_votes(), Finally.

After the data has been returned from the server, its handed off indirectly to set_votes().

view plain copy to clipboard print ?

function set_votes(widget) {
var avg = $(widget).data('fsr').whole_avg;
var votes = $(widget).data('fsr').number_votes;
var exact = $(widget).data('fsr').dec_avg;
$(widget).find('.star_' + avg).prevAll().andSelf().addClass('ratings_vote');
$(widget).find('.star_' + avg).nextAll().removeClass('ratings_vote');
$(widget).find('.total_votes').text( votes + ' votes recorded (' + exact + ' rating)' );
}

The first three lines are for readability, as those variable names are pretty long. So let’s take a look at what’s happening here.
Line 7: ‘avg’ is a whole number, representing the rounded vote average of this widget. Because it’s
a number 1-5, we can use it to find the proper star in the widget, and turn it, and the
preceding ones to our ‘filled’ graphic. Notice the use of .andSelf() to include the star that
we’ve selected.
Line 8: This is quite similar to line seven, but we’re removing the filled graphic from later stars. This
is necessary in case the average for this widget has gone down since the last vote.
Line 9: Here we’re updating the grey box underneath the widget, which shows a more precise rating,
and lets a visitor know how many votes have been cast.

Step 4. Let the Voting Begin

The final step for the UI is to enable voting. We’re going to add a click handler to each of the stars. This click handler will be responsible for sending the vote data to the server.

Create a simple CSS dropdown menu

2013-03-31T11:21:00.001+05:30

Learn to create a very simple CSS dropdown menu with solely HTML and CSS. This is a very useful and small dropdown menu without the use of javascript

UPDATE! I have updated the Dropdown code click here.

ul {

font-family: Arial, Verdana;

font-size: 14px;

margin: 0;

padding: 0;

list-style: none;

}

ul li {

display: block;

position: relative;

float: left;

}

li ul {

display: none;

}

ul li a {

display: block;

text-decoration: none;

color: #ffffff;

border-top: 1px solid #ffffff;

padding: 5px 15px 5px 15px;

background: #1e7c9a;

margin-left: 1px;

white-space: nowrap;

}

ul li a:hover {

background: #3b3b3b;

}

li:hover ul {

display: block;

position: absolute;

}

li:hover li {

float: none;

font-size: 11px;

}

li:hover a { background: #3b3b3b; }

li:hover li a:hover {

background: #1e7c9a;

}

Next is the HTML code. It is structured as nested lists so that even displaying the HTML source code without any CSS style will render it with a useful structure.

<li><a href="#">About Us</a>

<ul>

<li><a href="#">History</a></li>

<li><a href="#">Vision</a></li>

</ul>

</li>

<li><a href="#">Products</a>

<ul>

<li><a href="#">Cozy Couch</a></li>

<li><a href="#">Great Table</a></li>

<li><a href="#">Small Chair</a></li>

<li><a href="#">Shiny Shelf</a></li>

<li><a href="#">Invisible Nothing</a></li>

</ul>

</li>

<li><a href="#">Contact</a>

<ul>

<li><a href="#">Online</a></li>

<li><a href="#">Right Here</a></li>

<li><a href="#">Somewhere Else</a></li>

</ul>

</li>

</ul>

That is it, very simple and easy to customize! Click below for a live demo…

How To Make Android Proximity Alerts

2013-02-22T22:02:00.001+05:30

Smart-phones are taking over the mobile world, this is a fact. Since GPS devices are usually found embedded in those phones, there is already a notable rise in applications that take advantage of the offered geographical positioning functionality. A type of those applications is the one of Location Based Services, where the service exploits knowledge about where the mobile user is globally positioned at. Pretty common are also the applications that use geocoding (finding associated geographic coordinates from geographic data, such as a street address) and reverse geocoding (providing information based on given coordinates). One other aspect of that type of applications is the creation of proximity alerts. As their name suggests, these are alerts that get generated when the user is physically located near a specific Point Of Interest (POI). Proximity alert are going to be a “hot” thing the following years, since a lot of applications are going to make use of them, with the most prominent example being targeted advertising. In this tutorial I am going to show you how to take advantage of Android’s built-in proximity alert capabilities.
Before we begin, it would be helpful to have read introductory articles about location based application and/or geocoding. You might want to take a look at some previous tutorials of mine, such as “Android Location Based Services Application – GPS location” and “Android Reverse Geocoding with Yahoo API – PlaceFinder”. One other thing to note is that this tutorial was inspired by a very cool tutorial named “Developing Proximity Alerts for Mobile Applications using the Android Platform”. This is a four part tutorial, which gets a little complicated at some points and might intimidate a beginner. For that reason, I decided to provided a shorter and more straightforward tutorial.
What we will build is a simple application that stores the user’s coordinates for a point that interests him and then provide a notification when the user is near that point. The coordinates are retrieved on demand when the user is located at that point.
We begin by creating a new Eclipse project, named “AndroidProximityAlertProject” in our case. We also create a main activity for our application under the name “ProxAlertActivity”. Here is what the application’s main page will look like:

Here is the declaration file for the main UI layout, named “main.xml”:

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
>

    <EditText 
        android:id="@+id/point_latitude" 
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content"
        android:layout_marginLeft="25dip"
        android:layout_marginRight="25dip"
    />
    
    <EditText 
        android:id="@+id/point_longitude" 
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content"
        android:layout_marginLeft="25dip"
        android:layout_marginRight="25dip"
    />
        
    <Button 
        android:id="@+id/find_coordinates_button" 
        android:text="Find Coordinates"
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content" 
    />
    
    <Button 
        android:id="@+id/save_point_button" 
        android:text="Save Point"
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content" 
    />
    
</LinearLayout>

Let’s now get started with the interesting stuff. First of all, we need a reference to the LocationManager class, which provides access to the system location services. This is done via a call to the getSystemService method of our activity. We can then use the requestLocationUpdates method in order to request notifications when the user’s location changes. This is not strictly required when developing proximity alerts, but I will use it here in order to calculate the distance between the point of interest and the current user location. At any given time, we can call the getLastKnownLocation method and retrieve the last known location of a specific provider, in our case the GPS device. Finally, we will make use of the addProximityAlert method that can be used to set a proximity alert for a location given by specific coordinates (latitude, longitude) and a given radius. We can also optionally define an expiration time for that alert if we wish to monitor the alert for a specific time period. A PendingIntent can also be provided, which will be used to generate an Intent to fire when entry to or exit from the alert region is detected.
All these are translated into code as follows:

            float distance = location.distanceTo(pointLocation);
            Toast.makeText(ProxAlertActivity.this, 
                    "Distance from Point:"+distance, Toast.LENGTH_LONG).show();
        }
        public void onStatusChanged(String s, int i, Bundle b) {            
        }
        public void onProviderDisabled(String s) {
        }
        public void onProviderEnabled(String s) {            
        }
    }
    
}

In the onCreate method we hook up the location manager with a custom class that implements the LocationListener interface and allows to get notified on location changes via the onLocationChanged method. We will see how to handle the updates later. We also find the various UI widgets and attach OnClickListeners to the buttons.
When the user wants to find his current coordinates, the “populateCoordinatesFromLastKnownLocation” method is invoked. Inside that, we use the getLastKnownLocation method and retrieve a Location object. The EditTexts are then populated with the retrieved location information.
Similarly, when the user wants to save the point and provide alerts for that (“saveProximityAlertPoint”), the location info is first retrieved. Then, we save the latitude and longitude information as preference data using the SharedPreferences class and more specifically the SharedPreferences.Editor. Finally, we create a PendingIntent by using the getBroadcast static method. For the encapsulated Intent, we create an IntentFilter and use the registerReceiver method to associate a custom BroadcastReceiver with the specific intent filter. Note that this binding could alternatively be achieved in a declarative way using the manifest file.
Now let’s examine how we handle user’s location changes. In the implemented method of the “MyLocationListener” class, we extract the stored location info (“retrievelocationFromPreferences”) from the SharedPreferences class. Then, we use the distanceTo method to calculate the distance between the two locations, the current one and the one corresponding to the point of interest. This is done for debugging purposes, so that we know if we have actually entered the area around the point.
The final step is to handle the events of entering the area of the point of interest. This is done inside the “ProximityIntentReceiver” class that extends the BroadcastReceiver and responds to the custom intent that we attached to the location manager when adding the proximity alert. The handling occurs inside the onReceive method, which gets invoked upon event. Inside that, we retrieve the value of the KEY_PROXIMITY_ENTERING key from the associated intent, which indicates whether a proximity alert is entering (true) or exiting (false). The code is the following:

package com.javacodegeeks.android.lbs;

import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.graphics.Color;
import android.location.LocationManager;
import android.util.Log;

public class ProximityIntentReceiver extends BroadcastReceiver {
    
    private static final int NOTIFICATION_ID = 1000;

    @Override
    public void onReceive(Context context, Intent intent) {
        
        String key = LocationManager.KEY_PROXIMITY_ENTERING;

        Boolean entering = intent.getBooleanExtra(key, false);
        
        if (entering) {
            Log.d(getClass().getSimpleName(), "entering");
        }
        else {
            Log.d(getClass().getSimpleName(), "exiting");
        }
        
        NotificationManager notificationManager = 
            (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
        
        PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, null, 0);        
        
        Notification notification = createNotification();
        notification.setLatestEventInfo(context, 
            "Proximity Alert!", "You are near your point of interest.", pendingIntent);
        
        notificationManager.notify(NOTIFICATION_ID, notification);
        
    }
    
    private Notification createNotification() {
        Notification notification = new Notification();
        
        notification.icon = R.drawable.ic_menu_notifications;
        notification.when = System.currentTimeMillis();
        
        notification.flags |= Notification.FLAG_AUTO_CANCEL;
        notification.flags |= Notification.FLAG_SHOW_LIGHTS;
        
        notification.defaults |= Notification.DEFAULT_VIBRATE;
        notification.defaults |= Notification.DEFAULT_LIGHTS;
        
        notification.ledARGB = Color.WHITE;
        notification.ledOnMS = 1500;
        notification.ledOffMS = 1500;
        
        return notification;
    }
    
}

The code is pretty straightforward. After we determine whether we have an entering or exiting proximity alert, we are ready to provide a custom notification. To do so, we first take reference of the appropriate service, i.e. the NotificationManager. Through that service, we may send alerts to the user, wrapped around Notification objects. The notifications can be customized upon will and may include vibration, flashing lights etc. We also added a specific icon that will appear to the status bar. The setLatestEventInfo is preferred when we just want to add a basic title and text message. You can find more about notifications here. Additionally, we can use a PendingIntent in order to define an activity to be invoked when the user acknowledges the notification by clicking on it. However, to keep things simple, I do not use an intent to be launched in my example.
Finally, let’s see what the Android manifest file looks like:

<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="com.javacodegeeks.android.lbs"
      android:versionCode="1"
      android:versionName="1.0">
      
    <application android:icon="@drawable/icon" android:label="@string/app_name">
        
        <activity android:name=".ProxAlertActivity"
                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>     

    </application>
    
    <uses-sdk android:minSdkVersion="3" />
   
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION" /> 
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.VIBRATE" />

</manifest>

Nothing special here, just remember to add the necessary permissions, i.e.

We are now ready to test our application. Launch the Eclipse configuration. Then, go to the DDMS view of Eclipse and look for the “Emulation Control” tab. There, among other things, you will find the “Location Controls” section, which can send mock location data to the emulator. In the “Manual” tab, just hit the “Send” button, there are already some coordinates set up.

After that, the GPS provider will have a last known location that can provide upon request. So, hit the “Find Coordinates” button and this is what you will get:

Then, hit the “Save Point” in order to declare the current location as a point of interest. The location coordinates will be saved in the preferences and the proximity alert will be added to the location manager.
Next, let’s simulate the fact that the user leaves the location. Change the value of the coordinates, for example change latitude as follows: 37.422006 ? 37.522006. We are now quite far from the point of interest. Let’s suppose now that we are approaching it, thus change the latitude to a closer value, for example: 37.522006 ? 37.423006.

This is inside the radius of the point (this was set to 1000 meters) thus the alert is triggered and our receiver gets notified. There, we create our notification and send it via the notification manager. The notification appears at the status bar as follows:

That’s it, a quick guide on how to implement proximity alerts with the Android platform. You can find here the Eclipse project created for the needs of this tutorial.
