php serialize and unserialize

noreply@blogger.com (Merry@Jerry) — Wed, 20 Jul 2011 05:28:00 +0000

This process makes a storable representation of a value that is useful for storing or passing PHP values around without losing their type and structure.

<?php
    $the_array = array( "Merriet", "Jerry", "Drupal", "PHP" );
    $serialized = serialize($the_array);
    print $serialized.'<br/>';
    print_r(unserialize($serialized));
?>

Output:
Serialize: a:4:{i:0;s:7:"Merriet";i:1;s:5:"Jerry";i:2;s:6:"Drupal";i:3;s:3:"PHP";}
Unserialize: Array ( [0] => Merriet [1] => Jerry [2] => Drupal [3] => PHP )

drupal with jquery

noreply@blogger.com (Merry@Jerry) — Wed, 23 Feb 2011 07:38:00 +0000

Drupal.jsEnabled
This variable indicates whether or not the browser will support drupal.js and jquery.js. Returns true / false.

Drupal.attachBehaviors()
The Drupal Behaviors feature provides a standard method for attaching some particular information (called a behavior) to zero or more elements on a page.

Drupal.checkPlain()
It allow us to display HTML tags in browser.
example:
myString = "Add a line break using the <br/> tag.";
escapedString = Drupal.checkPlain(myString);
output: Add a line break using the <br/> tag.

Drupal.parseJson()
This function was intended to be used for parsing AJAX data that was returned from the server in the JSON (JavaScript Object Notation) format. JSON data looks like JavaScript.
Here's an example describing a person's name:
jsonString = "{'first': 'Merriet', 'last': 'Jerry'}";
name = Drupal.parseJson(jsonString);
name.first
Output: Merriet
The string is parsed and converted to an object. We can then use that object directly in JavaScript.

Drupal.encodeURIComponent()
It correctly converts other characters while preserving the slashes.
myString = 'node/1/calc%';
Drupal.encodeURIComponent(myString);
Output: node/1/calc%25

Drupal.getSelection()
This tool is used to find out what portion of a text area (<textarea></textarea>) is selected.
For example, when you select a section of text with your mouse, this function can be used to find out the starting and ending locations of the selection.
The Drupal.getSelection() function returns an object with two attributes: start and end. These two properties are integers which represent the beginning and ending of the selection.

Drupal.t()
This function's job is to take a string and perform any translation actions on it.
var params = {
"@siteName": "Example.Com",
"!url": "http://example.com/"
};
var txt = Drupal.t("The URL for @siteName is !url.", params);

Drupal.formatPlural()

for (i = 0; i < 6; ++i) {
alert( Drupal.formatPlural(i, "Johnny has 1 apple.", "Johnny has @count apples."));
}
This function takes these arguments:

A number (If it is 1, then the singular will be used, otherwise the plural form will be used.)
A singular string (in English).
A plural string (in English)

append() and appendTo() jQuery methods

noreply@blogger.com (Merry@Jerry) — Wed, 23 Feb 2011 05:52:00 +0000

An easily overlooked difference between append() and appendTo() is in the return value; both return jQuery objects. But where append() returns a jQuery object wrapping the thing(s) that have been appended to, the appendTo() call returns the elements that were appended.

//Create our content
var appendHTML = "<p>I'm going to be added to the DOM</p>";

//Select our element, then add the html
$("#container").append(appendHTML);

//Create our content, then select the element to append to
$(appendHTML).appentTo("#container");

Rotate content using jquery

noreply@blogger.com (Merry@Jerry) — Wed, 16 Feb 2011 11:36:00 +0000

Create the sticky_rotate.js

var StickyRotate = StickyRotate || {};
StickyRotate.init = function() {
var stickies = $(".sticky");
// If we don't have enough, stop immediately.
if (stickies.size() <= 1 || $('#node-form').size() > 0) {
return;
}
var highest = 100;
stickies.each(function () {
var stickyHeight = $(this).height();
if(stickyHeight > highest) {
highest = stickyHeight;
}
});
stickies.hide().css('height', highest + 'px');
StickyRotate.counter = 0;
StickyRotate.stickies = stickies;
stickies.eq(0).fadeIn('slow');
setInterval(StickyRotate.periodicRefresh, 7000);
};

StickyRotate.periodicRefresh = function () {
var stickies = StickyRotate.stickies;
var count = StickyRotate.counter;
var lastSticky = stickies.size() - 1;
var newcount;
if (count == lastSticky) {
newcount = StickyRotate.counter = 0;
}
else {
newcount = StickyRotate.counter = count + 1;
}
stickies.eq(count).fadeOut('slow', function () {
stickies.eq(newcount).fadeIn('slow');
});
};

Call the script by using
$(document).ready(StickyRotate.init);

var PrinterTool = {};
PrinterTool.windowSettings = 'toolbar = no, location = no,' + ' status = no, menu = no, scrollbars = yes, width = 650, height = 400';
PrinterTool.print = function (tagID) {
   var target = document.getElementById(tagID);
   var title = document.title;
   if(!target || target.childNodes.length === 0) {
   alert("Nothing to Print");
   return;
   }
   var content = target.innerHTML;
   var text = '<html><head><title>' + title +
   '</title><body>' + content + '</body></html>';
   printerWindow = window.open('', '', PrinterTool.windowSettings);

Setup drupal subsite in local machine

noreply@blogger.com (Merry@Jerry) — Mon, 14 Feb 2011 13:55:00 +0000

10 Steps to setup subsite in local machine with windows Environment.

1. Create a subfolder subsite under drupal6/sites/subsite.(drupal6 is an main site)

2. Copy the default.settings.php from sites/default folder and renamed as settings.php, then paste it into drupal6/sites/subsite/settings.php

3. Create folders themes and modules under sites/subsite/themes and sites/subsite/modules. Place the site specific themes and modules.

4. Open the file httpd-vhosts.conf from bin/apache/conf/extra/ httpd-vhosts.conf

5. Add the following code at the end of file.

DocumentRoot "E:/Jerry/wamp/www/drupal6"

ServerName subsite

</VirtualHost>

Note: drupal6 is an main site. The subsite folder under wamp/www/drupal6/sites/subsite

6. In windows system goto start > run (win+r) and type drivers and press ok.

7. Then open the folder etc. edit the file hosts.
Add the host name under default host like..
127.0.0.1 tobylove6
127.0.0.1 subsite

8. Add our sitename in browsers noproxy settings.

In Mozilla:

Method 1

* Open Tools >> options

* Select network tab under advanced tab.

* Click button settings.

* Choose no proxy and press ok.

Method 2

* Open Tools >> options

* Select network tab under advanced tab.

* Click button settings.

* Choose Manual proxy configuration and enter the proxy details.

* Enter subsite in noproxy for text box. Like localhost,subsite

* Then press ok.

9. Restart the apache server. Then run the subsite as http://subsite. It will show the drupal installation window.

10. Follow the drupal installation steps.

Setup Drupal multisite feature in Local machine

noreply@blogger.com (Merry@Jerry) — Mon, 27 Sep 2010 13:34:00 +0000

Setup Drupal's multisite feature in Local machine.

For that we have to follow the following three steps.

1. Add alias to our Apache configuration file

2. Redirecting all requests to index.php

3. Creating our settings.php

Add alias to our Apache configuration file

We want requests for the 3 subdirectories(emea, la, uk) to go to the same Drupal instance.We can do this using Apache's Alias functionality.

DocumentRoot “/xampp/htdocs/drupal”

Alias /emea C:/xampp/htdocs/drupal

Alias /la C:/xampp/htdocs/drupal

Alias /uk C:/xampp/htdocs/drupal

I'm supposing here Drupal's codebase is hosted in C:/xampp/htdocs/drupal on your machine

Redirecting all requests to index.php

Now that we're serving all requests from one codebase we have to redirect all requests to index.php. This needs to be done since all Drupal requests are served from one endpoint, called index.php. So we have to do the below changes in the .htaccess file in the same order as mentioned below.

RewriteCond %{REQUEST_FILENAME} !-f

RewriteCond %{REQUEST_FILENAME} !-d

RewriteCond %{REQUEST_URI} ^/emea/(.*)$

RewriteRule ^(.*)$ /emea/index.php?q=$1 [L,QSA]

RewriteCond %{REQUEST_FILENAME} !-f

RewriteCond %{REQUEST_FILENAME} !-d

RewriteCond %{REQUEST_URI} ^/la/(.*)$

RewriteRule ^(.*)$ /la/index.php?q=$1 [L,QSA]

RewriteCond %{REQUEST_FILENAME} !-f

RewriteCond %{REQUEST_FILENAME} !-d

RewriteCond %{REQUEST_URI} ^/emea/(.*)$

RewriteRule ^(.*)$ /uk/index.php?q=$1 [L,QSA]

RewriteCond %{REQUEST_FILENAME} !-f

RewriteCond %{REQUEST_FILENAME} !-d

RewriteCond %{REQUEST_URI} !=/favicon.ico

RewriteRule ^(.*)$ index.php?q=$1 [L,QSA]

Creating our settings.php

We can now have different settings (database, ...) for each site by creating a different settings file for each site. Place the settings.php for each file under a directory called after the domain name and subdirectory. In our example we would have the following setting files:

C:/xampp/htdocs/drupal/sites/default/settings.php -Base site Settings.php

C:/xampp/htdocs/drupal/sites/localhost.emea/settings.php -EMEA site Settings.php

C:/xampp/htdocs/drupal/sites/localhost.la/settings.php -LA site Settings.php

C:/xampp/htdocs/drupal/sites/localhost.uk/settings.php -UK site Settings.php

Now, start installing the site by using the below URLS

1. http://localhost – Base site

2. http://localhost/emea – EMEA site

3. http://localhost/la – LA site

4. http://localhost/uk – UK site

Enjoy the Drupal's multisite feature in the subdirectories.

MySQL Command-Line

noreply@blogger.com (Merry@Jerry) — Fri, 24 Sep 2010 17:08:00 +0000

shell> mysql –help

Connect to Server

shell> mysql -h host -u user -p

Enter password: ********

Disconnect from the Server

mysql> QUIT

On Unix, you can also disconnect by pressing Control-D.

Create Database

mysql> CREATE DATABASE menagerie;

Creating a database does not select it for use; you must do that explicitly. To make menagerie the current database, use this command:

mysql> USE menagerie

Database changed

Use a CREATE TABLE statement to specify the layout of your table:

mysql> CREATE TABLE pet (name VARCHAR(20), owner VARCHAR(20),

-> species VARCHAR(20), sex CHAR(1), birth DATE, death DATE);

Once you have created a table, SHOW TABLES should produce some output:

mysql> SHOW TABLES;

To verify that your table was created the way you expected, use a DESCRIBE statement:

mysql> DESCRIBE pet;

After creating your table, you need to populate it. The LOAD DATA and INSERT statements are useful for this.

To load the text file pet.txt into the pet table, use this statement:

mysql> LOAD DATA LOCAL INFILE '/path/pet.txt' INTO TABLE pet;

If you created the file on Windows with an editor that uses \r\n as a line terminator, you should use this statement instead:

mysql> LOAD DATA LOCAL INFILE '/path/pet.txt' INTO TABLE pet

-> LINES TERMINATED BY '\r\n';

mysql> SELECT VERSION(), CURRENT_DATE;

Keywords may be entered in any lettercase. The following queries are equivalent:

mysql> SELECT VERSION(), CURRENT_DATE;

mysql> select version(), current_date;

mysql> SeLeCt vErSiOn(), current_DATE;

It demonstrates that you can use mysql as a simple calculator:

mysql> SELECT SIN(PI()/4), (4+1)*5;

mysql> SELECT VERSION(); SELECT NOW();

Here is a simple multiple-line statement:

mysql> SELECT

-> USER()

-> ,

-> CURRENT_DATE;

If you decide you do not want to execute a command that you are in the process of entering, cancel it by typing \c:

mysql> SELECT

-> USER()

-> \c

The simplest form of SELECT retrieves everything from a table:

mysql> SELECT * FROM pet;

mysql> SELECT DATABASE();

mysql> SHOW TABLES;

mysql> DESCRIBE pet;

mysql> SELECT USER()
