Hi, I want to filter ArrayList, but I don't know if I filter it correctly or even is it possible. Here is my code:

public function getTopChildrenList() {

		$Childrens = $this->Children();		
			
		$limit = 4;
		
		$output = new ArrayList();

		foreach($Childrens as $C2) {
			$C2 = $C2->Children();	 
		        foreach($C2 as $C3) {					 
				$C3 = $C3->Children()->filter('Created:GreaterThan', '2011-11-11')->limit($limit);
				foreach($C3 as $C4) {
					$output->push($C4);
				 }					  
			}
		}

		$list = $output;

		return $list;  
	
}

I want to filter 7 days old items, but don't know how.. I if somebody know, please help.

Thanks :)

filter is the correct method to use and the filter looks good. You could debug the SQL for the DataList (to check the WHERE) by looking at $list->sql()

To be able to use the SearchFilters, you need a DataList. You can achieve the same effect as Children() by using something like that:

$C3 = $C3->stageChildren(false)->filter('Created:GreaterThan', '2011-11-11')->filterByCallback(function($item) {	
				return $item->canView();
			})->limit($limit);

Thank you both for answers :) Hope I will get it working:)
