Hiya people

 

i recently came into the posession of a oop templating class and im trying to modify it a little bit.

the modifications i have made make the script timeout.

 

i know exactly what is going on in the script and how to execute/access the methods and properties inside the class.

 

the original script had one set of 'repeaters' so that it could display one set of records from a database.

 

im trying to modify the script so that it can have more than one set of 'repeaters'

 

could someone please offer their advice on how to resolve this issue?

 

Thanks

 

templating class:

/*          PAGE MANAGEMENT CLASS          */
/*                                         */
/* Files that require this class will also */
/*   need to require the database class.   */
/*                                         */

}
?>

 

how i am calling the class:

<?php
# simple demonstration CMS system
# start session! Durrr
session_start();

#message array
$message_array = array();


require_once('class/page.php');
require_once('class/database.php');

$p = new Page();
$d = new Database();

# put the page and proc get variables into local variables
if (isset($_GET['p']) && $_GET['p'] != '') {
$page = $_GET['p'];
} else {
$page = 'index';
}
if (isset($_GET['proc']) && $_GET['proc'] != '') {
$proc = $_GET['proc'];
} else {
$proc = '';
}
# new Page object for output
$current_login = 'ca5095';
# check the login cookie; if it's not there pull in the login page
if (isset($_COOKIE['85c9d20051'])) {
if ($_COOKIE['85c9d20051'] == md5(serialize($valid). $d->seed)) {
	$current_login = $valid;
}
} elseif ($proc != 'login' && $current_login == 'ca5095') {
$p->parse('templates/admin_login.html');
die($p->html);
}
if ($proc == '') {
# normal pages
switch ($page) {
	case 'index' :
		$all_pages = $d->db_select('*', 'pages');

		$p->parse('templates/admin_template.html', array(), $all_pages);
	break; // index

	case 'images' :
		$images = $d->db_select('*', 'images', '1', 'ORDER BY id ASC');
		//echo'<pre>';print_r($images);die('</pre>');
		$p->parse('templates/images.html', array(), $images);
	break; //images

	case 'edit' :
		$pages = $d->db_select('*', 'pages', "`url` = '{$_GET['page']}'");
		if ($pages == array()) $pages[0] = array('url' => '0', 'heading' => '', 'body' => '');
		if ($pages[0]['url'] == '0') {
			$pages[0]['field'] = '<input name="url" type="text" id="url" />';
		} else {
			$pages[0]['field'] = $pages[0]['url'];
		}
		$pages[0]['body'] = html_entity_decode(br_remove($pages[0]['body']));
		$page_list = $d->db_select('*', 'pages'); 
		$p->parse('templates/edit.html', $pages[0], $page_list);
	break; // edit

	case 'test':
		$array1 = array();

		$array1[] = $d->db_select('*', 'pages');

		$array1[] = $d->db_select('*', 'images');

		$array1[] = $d->db_select('*', 'files');

		$p->parse('templates/test.html', array(), $array1);
	break;

}
echo $p->html;

#unset all session variables
unset($_SESSION['messagestate']);
unset($_SESSION['message']);


}

?>

 

templated page:

<!--ITEM 1-->
{{url}}<br>
<!--END OF ITEM 1--><br>
<br>
<br>
<br>
<!--ITEM 2-->
{{image_url}}<br>
<!--END OF ITEM 2--><br>
<br>
<br>
<br>
<!--ITEM 3-->
{{url}}<br>
<!--END OF ITEM 3-->
...

 

if you need anything else just ask.

im still new to OOP so im making this to practice

 

well, the good news is i managed to fix the timeout but the templete class isn't replacing the bits i need

this is the new class

 

the large comment inside template (); is the original codefor that function.
