Hello all users of TalkPHP

I have been reading and looking and writing user system. Now I had this idea to make this plug&play style plugin system so you only need to upload the plugin to ftp folder and active it from controlpanel.

So what I have now is this :

Code:

<?php

if( !defined( "INPROCESS" ) ){
	header("HTTP/1.0 403 Forbidden");
	die();
}
 include_once 'mysql'. EXT; 
class plugin extends mysql{  
 
 	var $mysql;
 	var $fullpath;
 	var $plugins = array();
 	
	function __construct() {
		
		$this->mysql = new mysql();
		
		if( phpversion( ) < 5 ){
            mysql::__construct( );
        }
        
        // Lets check all avaible plugins
       	$list = array();     

		if ( ($directoryHandle = opendir( $this->fullpath . '/plugins/' )) == true ) {  
			while (($file = readdir( $directoryHandle )) !== false) {  
			// Make sure we're not dealing with a file or a link to the parent directory  
				if( is_dir( $this->fullpath . '/plugins/' . $file ) && ($file == '.' || $file == '..') !== true )  
					array_push( $list, $file );  
			}  
		}  
		
		$results = $this->Fetch_Object('SELECT * FROM plugins');
		
		$newResult = array();
		// Create an array: 'plugin name' = 'active' (1 or 0)  
		foreach ( $results as $result ){  
			$newResult[$result->name] = $result->active;  
		}    
		
		// Register the active plugins 
		foreach( $list as $plugin ){  
			if($newResult[$plugin] == "1"){  
				$this->registerplug($plugin);
			}
		}  
	}
	
	function registerplug($plugin){
		require_once( $this->fullpath . "/plugins/$plugin/$plugin.plugin.php" );
 	}  	
 	
 	function hook($checkpoint){
 		// Cycle through all the plugins that are active  
  		foreach($this->plugins as $plugin){ 
    		if(!call_user_func($checkpoint))  
     			throw new Exception( "Cannot hook plugin ($plugin) at checkpoint ($checkpoint)" );  
   		}  
 	}
  
}
?>

And I use it like this ->

Code:

$plugin = new plugin;
$plugin->fullpath =  $system_folder;
if( phpversion() < '5' ) 
    $plugin->__construct( );

Now when I try to hook functions I use it like this :

Code:

$plugin->hook('Menu'); 
$plugin->hook('onLoad');

So the problem is that it wont print out "hello world" text which I asked it to do in both of those plugins.

Code:

class menu extends plugin {
    function Menu(){
        print 'Hello World!';
        return true;
    }
}

So what is wrong with this? Any suggestions? MySQL connections work 100% for sure (tested)
