I have never seen that technique before but $session->username is an OOP thing, so wherever you saw that - they have a class for their session.

Say if you had index.php and wanted to have ?action=search then you could do something like...

 

<?php
switch($_GET['action']) {
    case 'search';
    search_page();
    break;
    case 'about';
    about_page();
    break;
}

function search_page {
    echo('You are on the search page.');
}

function about_page {
    echo('You are on the about page.');
}
?>

 

You could also do something like this...

 

<?php
switch($_GET['action']) {
    case 'search';
    include('includes/search.php');
    break;
    case 'about';
    include('includes/about.php');
    break;
}
?>

 

I believe the technique is called query-stringing or something...

 

OOP is Object Oriented Programming, stay away from it until you know all the basics...

y GET n REQUEST always involve in this query string?

GET n REQUEST not only use in form?

thanks.

I don't know anything about the request super global but no it's not just for forms you can use it for other things too, whatever you want really.

[Cagecrawler]

The $_GET superglobal is used to pass variables across pages using the url.  For example, if you had "index.php?foo=bar", then you could access that as "$_GET['foo'] = bar".  $_POST is the superglobal mainly used for forms and $_REQUEST is sort of in between.  I've never needed to use $_REQUEST.

this technique called?

thanks..

As I have already said I believe it is called query-stringing but I really don't know, why does it matter what the technique is called so bad anyway?

[kratsg]

This is data passing via URL. It uses two methods, the $_GET method and the $_REQUEST method. ($_REQUEST is very unstable, do not even use this).

<?php header("Location: http://www.domain.com/users/".$session->username."/index.php"); ?>

 

The first url:

$action = $_GET['action']; //this will set $action to be "search"

The second url:

$gid = $_GET['gid']; //this will set $gid to be "184"

The third url is a header-redirect. Basically, you are right that it is OOP. They said something like:

$session = new Class();

In their "Class" is a variable called $username, they can call the variable within the class by saying

$session->username

The code above basically tells the browser to get the person's username from a session variable (using the Class(); to validate it) and redirect them to

$username/index.php

 

$_GET and $_POST are used to get data that was passed via forms.
