In addition to the URL variables:
$target_name = ‘target’;
$mode_name = ‘mode’;
$action_name = ‘action’;
It would be nice to have these additions:
$products_name = ‘products’;
$products_id_name = products_id’;
$category_name = ‘category’;
$category_id name = ‘category_id’;
$manufacturers name = ‘manufacturers’;
$manufacturers_id name = ‘manufacture_id’;
