How to make Dojo parse the html elements on page on load ?

2012-01-01T23:37:00.000+05:30

Dojo can parse the elements in the html and convert to Dojo or Dijit elements.

Include parseOnLoad config parameter after the script include tag.

<script src="http://ajax.googleapis.com/ajax/libs/dojo/1.6.0/dojo/dojo.xd.js"

    djConfig="parseOnLoad:true">

For some reasons if this is not worked try the below js code after dojo include

Cakephp - Adding meta data to a website

2010-06-14T17:10:00.002+05:30

meta(string $type, string $url = null, array $attributes = array(), boolean $inline = true)

This method is handy for linking to external resources like RSS/Atom feeds and favicons. Like css(), you can specify whether or not you'd like this tag to appear inline or in the head tag using the fourth parameter.



$html->meta(

'favicon.ico',

'/favicon.ico',

array('type' => 'icon')

);?> //Output (line breaks added)







$html->meta(

'Comments',

'/comments/index.rss',

array('type' => 'rss'));

?>



//Output (line breaks added)

Php- File upload limit changing using htaccess/php.ini

2010-05-13T13:43:00.002+05:30

FASTCGI / APACHE - Changing PHP File upload limit
Php default maximum upload limit is 8 MB. You can change the default settings by changing the server settings using .htaccess file or custom php5.ini file in the case of godaddy hosting.
First thing you have to find out is what your server API is?
print out php info of your hosted server.

See the Server API value.
If the Server API is apache You can do the following

1) Create a .htaccess file in the root folder of web server.
2) Put the following code in side the .htaccess file and save it.

php_value upload_max_filesize 20M
php_value post_max_size 20M
php_value max_execution_time 200
php_value max_input_time 200

This will work in godaddy hosting.

If your Server API is CGI/FASTCGI do the follwing .

create a php5.ini file and write in it

upload_max_filesize = 100M
post_max_size = 100M
output_buffering = on
max_execution_time = 1000
max_input_time = 1000
memory_limit = 64M

And upload it to your websites root folder.
Check the phpinfo and you can see the changes if it worked.Do not forget to put the file name php5.ini.

			$config['thumb_marker'] = $data['thumb_marker'];
			
			$config['maintain_ratio'] = TRUE;
			$config['width'] = $data['width'];
			$config['height'] = $data['height'];
			
			$this->CI->load->library('image_lib');
			$this->CI->image_lib->clear();
			$this->CI->image_lib->initialize($config);
			if ( ! $this->CI->image_lib->resize())
			{

Php - How to remove index.php from codeigniter url

2010-03-16T10:14:00.002+05:30

This is the best way to get ride of index.php from your website's url which is build using codeigniter framework.

RewriteEngine On
RewriteCond %{REQUEST_URI} ^system.*
RewriteRule ^(.*)$ /index.php/$1 [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]

copy and paste the above code in .htaccess file in your website root.Ensure that no extra whitspaces are included before or after the codes.

In config.php you can replace

$config['index_page'] = "index.php";
with this
$config['index_page'] = "";

Happy coding...

Php - Blacklist IPs - Simple way to blacklist IP's, good for instance when you want to stop certain IP ranges known to be spammers.

2009-06-26T13:02:00.000+05:30

?php

function IP_Blacklist($minimum = null, $maximum = null)
{
$ip = ip2long($_SERVER['REMOTE_ADDR']);

if (is_null($minimum) === false)
{
$minimum = explode('.', $minimum);

foreach ($minimum as $key => $value)
{
$minimum[$key] = ($value == '*') ? 0 : $value;
}

$minimum = ip2long(implode('.', $minimum));

if ($ip >= $minimum)
{
return false;
}
}

if (is_null($maximum) === false)
{
$maximum = explode('.', $maximum);

foreach ($maximum as $key => $value)
{
$maximum[$key] = ($value == '*') ? 255 : $value;
}

$maximum = ip2long(implode('.', $maximum));

if ($ip <= $maximum)
{
return false;
}
}

return true;
}
?>

Usage $_SERVER['REMOTE_ADDR'] = 195.22.23.24:

<?php
IP_Blacklist('195.22.23.*'); // false, blacklisted
IP_Blacklist('195.0.0.0', '195.255.255.255'); // false, blacklisted
IP_Blacklist('195.22.23.25', '195.22.23.255'); // true, clean

if (IP_Blacklist('195.22.23.*', '195.22.23.*') === false)
{
die('Nice try spammer.');
}
?>

Now, the action of that form has to direct to emailer.php as shown in the sample form.

1- Edit emailer_form.php (or any other form for that matter) by building the form you desire. See reference below for hidden field options.
2- Be sure the action of the form is aimed at the emailer.php file
3- Build the "Thanks" and/or "Error" page(s) if you choose the custom option
4- Edit the top few variable at the top of emailer.php to suit your needs, the available variables are as follows:

<?php
// recipient configuration - this is the array of recipients for the form, the number in the brackets
// must match the number in the "recipient_group" hidden field explained below
$tomail[0]="";
$cc_tomail[0]="";
$bcc_tomail[0]="";
$tomail[1]="";
$cc_tomail[1]="";
$bcc_tomail[1]="";
$tomail[2]="";
$cc_tomail[2]="";
$bcc_tomail[2]="";
// General Variables
// whether or not to check the referrer, 1 for yes, 0 for no
$check_referrer=1;
// domains allowed to use the emailer, with and without www
$referring_domains="http://domain.com/,http://www.domain.com/";
// Default Error and Success Page Variables
$error_page_title="Error - Missed Fields";
$error_page_text="Please use your browser's back button to return to the form and complete the required fields.";
$thanks_page_title="Message Sent";
$thanks_page_text="Thank you for your inquiry";
?>

HIDDEN FIELD OPTIONS
subject - The subject of the email to be sent
reply_to_field - The name of the field that should be put in the "from" field of the email
required_fields - a comma separated list of fieldname to be validated for content
required_email_fields - a comma delimited list of fields to be validated for valid email address syntax
recipient_group - the number that refers to the number in the brackets of the list of recipients to recieve this email
error_page - the filename (and path if necessary) to a custom error page, if missing or blank default text in variable above will be used
thanks_page - the filename (and path if necessary) to a custom thanks page, if missing or blank default text in variable above will be used
send_copy - whether or not to send a copy of the mail to the sender
copy_subject - subject of sent copy
copy_tomail_field - field of email address to the sender for the sent copy
mail_type - layout of email options are "vert_table" or "horz_table", anything else will result in plain text email
mail_priority - 1 is high, 3 is normal
return_ip - do you want the IP of the sender returned with the email if available? 1 is yes, 0 is no

NOTES:
> To call the form link to the emailer.php file NOT the emailer_form.php!
> DO NOT use spaces in the field names of your form. A good option is to use an underscore ("_") instead.
> When making the form, always include the <?php echo $fieldname; ?> as the value of each field. This will make the field populate with the previously entered information should someone not fill out all required fields and see the default error page.
> the recipients_group hidden field may seem confusing, but it is done this way to prevent spambots from harvesting actual email addresses from hidden fields the way many scripts do

PHP - Thumbnail script - Generate thumbnails on the fly.

2009-06-22T09:33:00.002+05:30

Thumbnails are basically a complicated yet effective way to save bandwidth. Although saving thumbnails as seperate images may make things simpler, generating thumbs on the fly help saving space and takes very little processing time in return.

php - Detect Alphabet only string with ctype_alpha

2009-04-07T11:09:00.001+05:30

Detect Alphabet only string with ctype_alpha

There are times when you need a function that can detect strings which contains onlyalphabetic characters. While is_numeric can validate a given string contains numeric character, there are no is_* function variation exist which can do the same for alphabetic strings.

However, you can still test for alphabetic string using ctype_alpha() function. Example usage :

if (ctype_alpha($testcase)) {

echo 'The string $testcase consists of all letters.\n';

} else
{

echo 'The string $testcase does not consist of all letters.\n';

}

}

Convert your PDFs to MS Word

2009-03-31T10:17:00.001+05:30

There are several well-regarded, free ways to take advantage of the Print function to transform just about any file to a PDF. PrimoPDF and doPDF sit at the top of the list, but what about reverse engineering that conversion? Converting in the other direction, from a PDF to a Microsoft Word-compatible format like DOC or RTF is trickier.

For one thing, there's a lot of crap out there. Many PDF-to-DOC converters have similar or even identical names, differentiated sometimes by nothing more than a cunning tap of the space bar. Many offer features that are hamstrung in various ways unless you pay for an upgrade, and just about all of them offer imperfect conversions. Even with these problems, though, you can get a reasonable conversion from the four programs and three Web-based services listed below.

Sometimes right: Some PDF to Word Converter 1.5

(Credit: Screenshot by Seth Rosenblatt/CNET)

Some PDF to Word Converter 1.5: A basic but uncluttered interface introduces all of the program's conversion options in a sidebar on the right. Some handles batch conversions, converts outer fonts into text and embedded fonts into images, and supports both All Pages and page-range specific conversions. It can remove graphics on demand from the output document, which is always in the RTF format, and supports encryption.

The program suffers from two big drawbacks: the conversions aren't always the cleanest, with occasional image and text overlaps, and there's noticeable image deterioration. In place of drag-and-drop to add PDFs, you can add an entire folder via the folder icon. Some of the interface's option descriptions could be better phrased, too: "delete all graphics" with an option of "false" or "true" really could be posed better as "remove all graphics" and "yes" or "no."

Free PDF to Word Doc Converter 1.1 makes you jump through hoops for a great end result.

(Credit: Screenshot by Seth Rosenblatt/CNET)

Free PDF to Word Doc Converter 1.1 also gets a few things wrong, but eventually lands you the DOC output you want. Impressively, it offers one of the cleanest and most accurate free PDF-to-DOC conversions of the programs tested. You can change the output path and name, convert an entire document or just specific pages, and ditch images in the source PDF if need be. The final output will give you a pitch-perfect conversion.

From there, it goes a bit downhill. The option to open the output DOC in WordPad didn't function when we tested it, nor did the All Pages button. You can work around this by choosing Page Number instead of All Pages (Page Number defaults to the full page count), but it's still irritating. The other big frustration is that while the program is free, after five conversions you're asked to answer a math question a bit harder than the average Captcha. Batch conversion and encryption support are missing, too. If Free PDF to Word Doc Converter's bumpy ride didn't result in such a smooth landing, it wouldn't be worth touching.

Free PDF to Word Converter 1.3: common name, common problems.

(Credit: Screenshot by Seth Rosenblatt/CNET)

Free PDF to Word Converter 1.3 shares many things in common with its competitors besides a similar name: there's an imperfect balance of useful features and a perfect output. What's wrong: there's no drag-and-drop support, and you should be prepared for some minor yet annoying formatting errors, with occasional and minor word and image overlap.

What's right: The program can batch convert PDFs without being restricted to specific folders, can change your output destination, and put out either RTF or DOC. There's support for high levels of security, with space to provide passwords from the PDF owner and the PDF user. You can remove graphics on conversion and micro-manage the spaces between words and text boxes. It's fine for image-free PDFs, but somewhat less than exact with others.

Advanced PDF to Word Converter Free 5.0: nearly-perfect output.

(Credit: Screenshot by Seth Rosenblatt/CNET)

Advanced PDF to Word Converter Free 5.0 nearly crashes and burns on takeoff, but surprisingly leaves you with a nearly-perfect document. It will ask you to reboot on installation, which makes sense for programs that have deep hooks in your operating system but is a clarion warning for such a simple converter. However, as with all these converters, it's the final output that counts the most, and this program's final DOC output looks pretty good.

There's no support for encrypted PDFs, and when you convert or close the program, there's a nag screen to get you upgrade. Batch conversion, RTF and TXT output, and image deletion are restricted to the paid upgrade. The program does offer drag-and-drop additions, adding an entire folder, and user-selected output folders and output renaming. OpenOffice.org users will appreciate that this converter puts out a DOC that OpenOffice Writer can cleanly read images from--unlike many of the others. The biggest problem, of course, is that there is still some image quality degradation and minor text alignment problems.

OpenOffice users should take note that during these tests, I found that the OpenOffice Writer doesn't always play nicely with Rich Text Formatting. There are several free online conversion options as well, and they tend to have better output than the desktop programs.

You can send your PDF as an attachment to Adobe, and within a few minutes they'll send you back either a plain text TXT or HTML file. The service is basic but extremely fast. As long as you don't mind the lack of frills, you can e-mail pdf2txt@adobe.com for the plain text conversion and pdf2html@adobe.com for HTML output, although the HTML service wasn't working when I tested it. More details are here.

PDF to Word, from Nitro PDF.

(Credit: Screenshot by Seth Rosenblatt/CNET)

Nitro PDF, the makers of PrimoPDF, offer a glossy interface for their online PDF to Word format converter. Clearly delineated instructions guide you through uploading your PDF, choosing an output format--either DOC or RTF--and entering your e-mail address. The conversion took a bit longer than Adobe's, but it's worth the wait. The conversion output is a perfect document, precisely the kind of painless process that most of the downloadable options lack. There's no support for encryption, nor for batches, but Nitro's service gets high marks for its precise and fast conversion. Apparently, there are plans to incorporate the PDF-to-Word feature in future editions of Nitro PDF.

There are two other PDF-to-Word services worth mentioning: Koolwire and Zamzar. Koolwire will convert PDFs up to 10MB, but it can also handle DOC, XLS, PPT, VSD, MPP, RTF, TXT, JPEG, GIF, PNG, and MS Office 2007 formats like DOCX. Unlike the other services, clicking on their Web site opens an e-mail to which you only need to attach your PDF and then hit Send. The PDF comes out as RTF, with very minor image degradation and no formatting problems.

Zamzar's uploading interface.

(Credit: Screenshot by Seth Rosenblatt/CNET)

Zamzar will convert PDFs up to 100MB at a time, and in addition to converting your PDF into DOC or RTF, it can output ODT, TXT, PS, and PNG. It can handle batch conversion, as long as you don't mind uploading the files one at a time. When it finishes converting, you receive a link that stays active for 24 hours from which you can download your converted files one at a time or all at once in a ZIP. There was minor image degradation, similar to what Koolwire spit out, and one instance of a formatting error.

Overall, there is no option that can be declared 100 percent perfect. Where one service--whether it's online or desktop--fails, it also tends to offer a better interface, or more conversion options than others. The reverse also seems to hold true, where the best conversions are not always buttressed by the greatest of user experiences. Nitro PDF's PDF-to-Word Web site wins for its output and usability, but if you must go with a desktop client I'd choose Free PDF to Word Doc Converter 1.1 for the resulting document only. If you don't mind minor hiccups, but need a better user experience or more conversion options, Zamzar and Free PDF to Word Converter 1.3 are probably what you need.

PHP - redirect page

2009-03-25T13:06:00.002+05:30

In this tutorial I will show you how to redirect pages in PHP. You can find all important aspects and code examples about PHP redirecting.

To make a redirection you can use the header() function. This function send a raw HTTP header to the browser. As result the browser will be redirected to the page defined in this new HTTP header. You only have to take care that header() must be called before any actual output is sent. It means you can not use and html tags, echo or print functions. Below is an example how to use redirection in PHP:

<?php

header('Location:http://phpcodetutorials.blogspot.com');

?>

The only thing you have to do is to change the URL inside the header parameter.

However if you write the echo before the redirection you will get an error like this:

Warning: Cannot modify header information - headers already sent by

To avoid this problem you can use PHP output buffering as follows:

<?php

ob_start();

echo "Test";

header("Location: http://www.php.net");

ob_flush();

?>

php- Regular Expressions simple functions and common reqular expressions

2009-03-17T11:34:00.002+05:30

Regular Expressions

We will use simple functions which return TRUE or FALSE.
$regex will serve as our regular expression to match against and $text will be our text.


function do_reg($text, $regex)
{  
  if (preg_match($regex, $text))
  {   
      return TRUE;  
  }   
  else {   
        return FALSE;  
      }
}

The next function will get the part of a given string ($text) matched

by the regex ($regex) using a group srorage ($regs). By changing the

$regs[0] to $regs[1] we can use a capturing group (in this case griup

1) to match against. The capturing group can also have a name

($regs['groupname']):


function do_reg($text, $regex, $regs) {  

if (preg_match($regex, $text, $regs))
{   
    $result = $regs[0];  
}   
else {
  
   $result = "";  

   }  

 return $result;

 }


The following function will return an array of all regex
 matches in a given string ($text):

function do_reg($text, $regex)
{  
 preg_match_all($regex, $text, $result, PREG_PATTERN_ORDER);
 
 return $result = $result[0];

}

 Next we can iterate (loop) over all matches in a string ($text)
and output the results:


function do_reg($text, $regex)
{  

preg_match_all($regex, $text, $result, PREG_PATTERN_ORDER); 

for ($i = 0; $i < count($result[0]); $i++)
{  
  $result[0][$i];
 }

}

 Extending the above one we can iterate over all matches ($text)
and capture groups in a string ($text):


function do_reg($text, $regex)
{  
preg_match_all($regex, $text, $result, PREG_SET_ORDER);

for ($matchi = 0; $matchi < count($result); $matchi++)
 {   
  for ($backrefi = 0; $backrefi < count($result[$matchi]); $backrefi++)
  {   
     $result[$matchi][$backrefi];  
  } 
}

}

 Now lets see some useful regular expressions

//Address: State code (US) '/\\b(?:A[KLRZ]|C[AOT]|D[CE]|FL|GA|HI|I[ADLN]|K[SY]|LA|M[ADEINOST]|N[CDEHJMVY]|O[HKR]|PA|RI|S[CD]|T[NX]|UT|V[AT]|W[AIVY])\\b/'  //Address: ZIP code (US) '\b[0-9]{5}(?:-[0-9]{4})?\b'  Dates

Mysql - Add New MySQL User - PHP MySQL Tutorial

Add New MySQL User - PHP MySQL Tutorial

Add New MySQL User

For adding a new user to MySQL you just need to add a new entry to user table in database mysql. Below is an example of adding new user phpcake with SELECT, INSERT and UPDATE privileges with the password mypass the SQL query is :

mysql> use mysql;
Database changed

mysql> INSERT INTO user (host, user, password, select_priv, insert_priv, update_priv) VALUES ('localhost', 'phpcake', PASSWORD('mypass'), 'Y', 'Y', 'Y');
Query OK, 1 row affected (0.20 sec)

mysql> FLUSH PRIVILEGES;
Query OK, 1 row affected (0.01 sec)

When adding a new user remember to encrypt the new password using PASSWORD() function provided by MySQL. As you can see in the above example the password mypass is encrypted to 6f8c114b58f2ce9e.

Notice the the FLUSH PRIVILEGES statement. This tells the server to reload the grant tables. If you don't use it then you won't be able to connect to mysql using the new user account (at least until the server is reloaded).

You can also specify other privileges to a new user by setting the values of these columns in user table to 'Y' when executing the INSERT query :

Select_priv
Insert_priv
Update_priv
Delete_priv
Create_priv
Drop_priv
Reload_priv
Shutdown_priv
Process_priv
File_priv
Grant_priv
References_priv
Index_priv
Alter_priv

Php - File writer class - write files and take its backups so that it can be easily reverted

2009-02-09T15:30:00.001+05:30

File Writer is a simple class designed to make writing files, or appending to files, much easier. It also has optional functionality to take backups of files it writes to so that changes can be reverted easily.

Usage: Example

<?PHP
//Include the main class file
include("main.php");

//Create a new file_writer object
$file = new file_writer;

//Write to a new file
$file->write("test.txt", "Test Test Test");

//Append more text to the file
$file->append("test.txt", "\r\nTest Test Test");
?>

main.php

<?PHP
//Should file_writer take backups of files
define("WRITER_BACKUP", TRUE);

//Where should file_writer store backups
define("WRITER_RESTORE_DIR", "./restore");

//Should file_writer lock files while writing to them
define("WRITER_LOCK_FILES", TRUE);

class file_writer
    {
    public $files = array();

    function __construct()
        {

        }

    function write($file, $content)
        {
        $date = date("d-m-Y_his");
        //Copy the original file to the restore dir
        if(file_exists($file))
            {
            if(WRITER_BACKUP)
                {
                copy($file, WRITER_RESTORE_DIR."/".$date."_".$file);
                }
            }

        if(!isset($files[$file]))
            {
            //Make the file handle
            $files[$file] = fopen($file, "w");
            if(WRITER_LOCK_FILES)
                {
                flock($files[$file], LOCK_EX);
                }
            }

        //Overwrite the file
        fwrite($files[$file], $content);
        }

    function append($file, $content)
        {
        $date = date("d-m-Y_his");
        //Copy the original file to the restore dir
        if(file_exists($file))
            {
            if(WRITER_BACKUP)
                {
                copy($file, WRITER_RESTORE_DIR."/".$date."_".$file);
                }
            }

        if(!isset($files[$file]))
            {
            //Make the file handle
            $files[$file] = fopen($file, "a");
            if(WRITER_LOCK_FILES)
                {
                flock($files[$file], LOCK_EX);
                }
            }

        //Overwrite the file
