Adding an ID to the Add to Cart Button of the Plugin

You can add an ID tag to the add to cart button form using the following filter hook of the plugin.

wspsc_add_cart_button_form_attr

Below is an example PHP code that shows you how it works:

add_filter('wspsc_add_cart_button_form_attr', 'add_cart_button_custom_id');
function add_cart_button_custom_id($attr)
{
    $attr .= 'id="my_custom_id_123"';
    return $attr;
}

The above example code will add the ID of “my_custom_id_123” to the add to cart button form.
