Thema: Erstes Plugin Problem mit Suchfunktion

Hallo zusammen,

Warning: Invalid argument supplied for foreach() in /xxx/xx/htdocs/pizza/plugins/search/pizza.php on line 87

Anbei der Code:

Code:

<?php
// no direct access
defined( '_JEXEC' ) or die( 'Restricted access' );

$mainframe->registerEvent( 'onSearch', 'plgSearchPizza' );
$mainframe->registerEvent( 'onSearchAreas', 'plgSearchPizzaAreas' );

/**
 * @return array An array of search areas
 */
function &plgSearchPizzaAreas() {
	static $areas = array(
		'pizza' => 'Pizza'
	);
	return $areas;
}


function plgSearchPizza( $text, $phrase='', $ordering='', $areas=null )
{
	$db		=& JFactory::getDBO();
	$user	=& JFactory::getUser();

	if (is_array( $areas )) {
		if (!array_intersect( $areas, array_keys( plgSearchPizzaAreas() ) )) {
			return array();
		}
	}

	// load plugin params info
 	$plugin =& JPluginHelper::getPlugin('search', 'pizza');
 	$pluginParams = new JParameter( $plugin->params );

	$limit = $pluginParams->def( 'search_limit', 50 );

	$text = trim( $text );
	if ($text == '') {
		return array();
	}
	$section 	= JText::_( 'Pizza' );

	$wheres 	= array();
	switch ($phrase) 
	{
		case 'exact':
			$text = $db->getEscaped($text);
			$wheres2 	= array();
			$wheres2[] 	= "LOWER(a.text) LIKE '%$text%'";
			$wheres2[] 	= "LOWER(a.pizza) LIKE '%$text%'";
			$where 		= '(' . implode( ') OR (', $wheres2 ) . ')';
			break;

		case 'all':
		case 'any':
		default:
			$words 	= explode( ' ', $text );
			$wheres = array();
			foreach ($words as $word) {
				$word = $db->getEscaped($word);
				$wheres2 	= array();
				$wheres2[] 	= "LOWER(a.text) LIKE '%$word%'";
				$wheres2[] 	= "LOWER(a.pizza) LIKE '%$word%'";
				$wheres[] 	= implode( ' OR ', $wheres2 );
			}
			$where 	= '(' . implode( ($phrase == 'all' ? ') AND (' : ') OR ('), $wheres ) . ')';
			break;
	}

	switch ( $ordering ) 
	{
		default:
			$order = 'a.text ASC';
			break;

	}

	$query = "SELECT * FROM #__pizza AS a"
         . "\n WHERE ( $where )"
         . "\n AND published = '1'"
         . "\n ORDER BY $order";
	;
	
	//echo $query; die();
	$db->setQuery( $query, 0, $limit );
	$rows = $db->loadObjectList();
	
	foreach($rows as $key => $row) {
		$rows[$key]->href = 'index.php?option=com_pizza&view=pizza';
	}

	return $rows;
}
?>

Danke für eure Hilfe

es ist die Zeile

Code:

foreach($rows as $key => $row) {

wenn ich jetzt vor der Schleife eintrage

Code:

print_r($rows);
exit;

bekomme ich eine weisse Seite.
