$div reserved variable

Some system vars are available in the templates. This vars are provided by the engine. The following table shows the system vars:

|System var|Description| |---|---| |div.now|The result of time() PHP function| |div.post|$_POST| |div.get|$_GET| |div.server|$_SERVER| |div.session|$_SESSION| |div.version|div::$__version| |div.script_name|The cuurent script file name - $_SERVER['SCRIPT_NAME']| |div.ascii|The ASCII chars. For example, the {$div.ascii.64} to replace with character 64 (@ symbol). You don't made a mistake, this replacement is different to use the HTML entities just as "@".|

Now then, all the variables of the system are not enabled by default. The system vars enabled by default are div.now, div.version, div.get and div.post.

If you need enable some system vars use the method div::enableSystemVar($varname). If you need disable a system var use the method div::disableSystemVar($varname).

Example

index.php

<?php
	
session_start();
	
include 'div.php';
	
div::enableSystemVar('div.session');
	
if (isset($_GET['user'])){
	if ($_GET['user'] == 'peter'){
		$_SESSION['user'] = $_GET['user'];
	}
}
	
echo new div('index.tpl');

index.tpl

?$div.session.user
	?$div.get.user
		- Welcome {$div.get.user}
	@else@
	 	- Access denied for user {$div.session.user}
	 	- Show the login form
	$div.get.user?
@else@
	Show the login form
$div.session.user?

Output
