Conditional Shipping and Payments for WooCommerce

Hi,

My theme, Flatsome, as I’d imagine many themes are doing nowadays, add products to cart via ajax. The problem is, in “/includes/abstracts/class-wc-csp-abstract-restriction.php,” you have an “is_admin” check in the function “get_matching_rules_map.” Because the products are being added to cart via ajax, thus using admin-ajax.php, the admin check – starting on line 794 – returns true and the rules are therefore not applied due to the function bailing before the rules map is generated.

I have a suggested fix.

Replace:
// Bail out early and not run if we’re on wp-admin.
if ( is_admin() ) {
return array();
}

With (something like):
// Bail out early and do not run if we’re in wp-admin.
$script_filename = $_SERVER[ ‘SCRIPT_FILENAME’ ] ?? ”;
$script_filename = basename( $script_filename );
if ( wp_doing_ajax() && $script_filename === ‘admin-ajax.php’ ) {
$referer = $_REQUEST[ ‘_wp_http_referer’ ] ?? ( $_SERVER[ ‘HTTP_REFERER’ ] ?? ” );
$referer = wp_unslash( $referer );
$admin_path = admin_url();
$admin_path = basename( $admin_path );

if ( ! $referer || ( stripos( $referer, $admin_path ) > 0 ) ) {
return array();
}
} elseif ( is_admin() ) {
return array();
}

This will essentially determine if the admin ajax request is coming from the frontend and will continue to generate the rule maps. I have tested this on my client’s store, rpmpower.com, and it’s now working as it should be – restricting certain shipping methods depending on the product and shipping class(es) in the cart.

The only other option would be to toggle the add to cart via ajax setting to off in Flatsome, while I’d imagine other themes may not even have such a setting, and if I’m honest, I’d rather not do that anyway.

Thanks for your time and consideration.

Best,
Dave
