Ok, false alarm. The code above was wrong. @elliot Some people over on the Stack Exchange forum are saying I shouldn’t be using a LIKE compare, and an IN instead when using arrays.

Not sure which is right. But when I try to use an IN compare, I get a blank page when querying my posts.

add_action('pre_get_posts', 'my_pre_get_posts');
function my_pre_get_posts( $query ) {
	if( is_admin() ) {
		return;
	}
	$meta_query = $query->get('meta_query');
        if( !empty($_GET['type']) ) {				
        	$type = explode('|', $_GET['type']);	

	    	$meta_query[] = array(							
                'key'		=> 'type',
                'value'		=> $type,
                'compare'	=> 'IN',
            );
        }
	$query->set('meta_query', $meta_query);
	return;	// always return
}
