Assign a value to a variable.

Source

class.PHPTemplateLayer.inc.php

Parent Class

Example Usage


$PHPTemplateLayer->assign("variablename",$variablevalue);
$PHPTemplateLayer->assign("_ROOT.variablename",$variablevalue);

Usage Notes

A variable can be repeated any number of times in your template. If the variable is contained within a block in your template HTML, it's value must be assigned after that block is defined (but before any other block is defined) in your PHP code. If you need to assign a variable to an HTML area outside any block (for example after creating a block) you can do this by assigning the variable to the template's "root". You can assign different values to the same variable for the template's "root" and for different blocks.

Parameters
$variablename
(string) (Required)
The tag used in your HTML template to represent $variablevalue.
$variablevalue
(string) (Required)
The value to apply to $variablename.

Examples

Most basic example.


<html>
<head>
<title>Example</title>
</head>
<body>
<p>Your name is *{name}*</p>
</body>
</html>


<?php
include_once("class.PHPTemplateLayer.inc.php");

$PHPTemplateLayer = new PHPTemplateLayer();
$PHPTemplateLayer->prepare("template.htm");

$PHPTemplateLayer->assign("name","Dave");

$PHPTemplateLayer->display();
?>

Assigning a variable to the document "Root" from within a block.


<html>
<head>
<title>Example</title>
</head>
<body>
<p>Your name is *{name}*</p>
<!-- START BLOCK : MYNAME -->
<p>But my name is *{myname}*</p>
<!-- END BLOCK : MYNAME -->
</body>
</html>


<?php
include_once("class.PHPTemplateLayer.inc.php");

$PHPTemplateLayer = new PHPTemplateLayer();
$PHPTemplateLayer->prepare("template.htm");

$PHPTemplateLayer->block("MYNAME");
$PHPTemplateLayer->assign("myname","Paul");
$PHPTemplateLayer->assign("_ROOT.name","Dave");

$PHPTemplateLayer->display();
?>

Using an associative array to assign values.


<html>
<head>
<title>Example</title>
</head>
<body>
<p>Your name is *{yourname}* but my name is *{myname}*</p>
</body>
</html>


<?php
include_once("class.PHPTemplateLayer.inc.php");

$PHPTemplateLayer = new PHPTemplateLayer();
$PHPTemplateLayer->prepare("template.htm");

$PHPTemplateLayer->assign(Array(yourname => "Dave",myname => "Simon"));

$PHPTemplateLayer->display();
?>

<body>
<form name="quote" action="" method="post">

$PHPTemplateLayer = new PHPTemplateLayer();
$PHPTemplateLayer->prepare("template.htm");

	if($_POST['submit'])
	{
	$PHPTemplateLayer->assign("name",$_POST['name']);

		if($_POST['gender'] == "Male")
		{
		$PHPTemplateLayer->assign("maleselected",'selected="selected"');
		$PHPTemplateLayer->assign("femaleselected",'');
		}
		else
		{
		$PHPTemplateLayer->assign("maleselected",'');
		$PHPTemplateLayer->assign("femaleselected",'selected="selected"');
