Tipp: Using a regular object with the template engine (eZSimpleObject)

Tuesday 11 May 2004 7:32:58 am

Usage:

    $tpl->setVariable( 'skin', eZSkin::instance($skinid) );
    $tpl->setVariable( 'error', new eZError("This is a error") );

The classes

<?php
include_once('extension/siteskins/classes/ezsimpleobject.php');
class eZSkin extends eZSimpleObject
{
	function eZSkin($id=null)
	{
		$this->co = &eZContentObject::fetch($id);
		$treenodep = &eZContentObjectTreeNode::fetch($this->co->mainParentNodeID());
		$this->parent = &eZContentObject::fetch($treenodep->attribute('contentobject_id'));
		$com = &$this->co->attribute('data_map');
		$pam =&$this->parent->attribute('data_map');
		$this->id = $com["id"]->content();
		$this->extension = $pam["extension"]->content();
	}
	function &instance($id)
	{
		return parent::instance($id,"ezskin");
	}
	var $co;
	var $parent;
	var $extension;
	var $id;
}
include_once('extension/siteskins/classes/ezsimpleobject.php');
class eZError extends eZSimpleObject
{
	function eZError( $text, $type=null,$number=null)
	{
		if ($text)
			$this->text=$text;
		if ($type)
			$this->error['type']=$type;
		if ($number)
			$this->error['number']=$number;
	}
	function &instance($id)
	{
		return parent::instance($id,"ezerror");
	}
	var $text;
	var $error;
}
