Reply To: Passing a custom callback function and sorting based on the return.

Hi Gabe,

You are looking for the asp_results hook. That lets you make changes to the final results array before it is printed to the output.

In you case, I would start of with something like this:

add_filter( 'asp_results', 'asp_custom_results_order', 10, 1 );
function asp_custom_results_order( $results ) {
	$front = array(); // Results prioritized
	$back = array();  // Rest of the results
	
	// Parse through each result item
	foreach ($results as $k=>&$r) {
		if ( isset($r->post_type) ) {
			if ( your_function_to_check($r->id, get_current_user_id() ... ) ) {
				$front[] = $r;
			} else {
				$back[] = $r;
			}
		} else {
			$back[] = $r;
		}
	}

	return array_merge($front, $back);
}

This code skeleton helps you separate the results into two parts – front and back. The $front array goes to the front of the list, the $back contains the rest of the results. Then you can go through all of the results, check whatever you need, and put the result into either the $front of the $back.
