If you are creating a custom query loop or a custom plugin, you might want to perform some additional tasks like setting/resetting specific data before the loop runs. (@since 1.7.2)
// Perform certain action before the loop of query element oklvcq
add_action( 'bricks/query/before_loop', function( $query, $args ) {
if ( $query->element_id !== 'oklvcq' ) {
return;
}
// $args is an array of the element settings
// Perform your own logic here
}, 10, 2 );
