NYCPHP Meetup

Ok i am having some problems with this now.

I have tracked down where it is going wrong but i cannot see why it is doing so.

You will find all of my code at the bottom of this email.

$et->Menu()->Draw( $et->User()->Level() );

this will basically call the constructor for the Menu.class.php file.

the constructor will use a database connection to grab all menu
groups, and for each of the groups grab all the items for that group.

The issue i am having is that it seems to set the items and thier
properties, but when i retrieve them with the Draw method it shows
them as empty objects.

here is the results printed to the screen (from the Draw Method)

General
Files
Community
Control Panel

when i do a count( $items ) it returns 0 for some reason :(

Here is my code.


class Menu {
	static private $_groups;

	public function __construct( $db ) {
		$this->_groups = array();
		$res = $db->Query( "SELECT id, title, req_level, display_order FROM
menu_groups" );
		// make sure there are some groups in the database
		if( $db->NumRows( $res ) > 0 ) {
			// loop through the groups and add them to the menu
			while( $group = $db->FetchArray( $res ) ) {
				// add the group and set the info
				$g = $this->Group( );
				$g->Title( $group['title'] );
				$g->Level( $group['req_level'] );
				// get all items for this group
				$qry = $db->Query( "SELECT id, title, req_level, display_order
FROM menu_items WHERE mgroup=".$group['id'] );
				// make sure there are some menu items in this group
				if( $db->NumRows( $qry ) > 0 ) {
					// loop and add the items
					while( $item = $db->FetchArray( $qry ) ) {
						// add the item.
						$i = $g->Item( );
						$i->Title( $item['title'] );
						$i->Link( $item['link'] );
						$i->Level( $item['req_level'] );
					}
				}
			}
		}
	}

	static public function Group( $index = -1 ) {

		if( ( $index == -1 ) && ( count( self::$_groups ) != 0 ) ) $index =
count( self::$_groups );
		else $index = 0;
		if( self::$_groups[$index] == null ) {
			self::$_groups[$index] = new MenuGroup();
		}
		return self::$_groups[$index];
	}

	public function Draw( $level ) {
		foreach( self::$_groups as $group ) {
			// make sure the user has req level for this menu group
			if( $level >= $group->Level() ) {
				echo $group->Title().'<br>';
				$items = $group->GetItems();
				echo count($items);
				foreach( $items as $item ) {
					// make sure the user has req level for this menu item
					if( $level >= $item->Level() ) {
						echo '&nbsp; &nbsp;<a
href="'.$item->Link().'">'.$item->Title().'</a><br>';
					}
				}
			}
		}
	}
}
