Expression contains disallowed function calls.

Hi @matthijscremers,

Sorry to hear that you ran into these issues while moving your logic code to the new snippet system.

This error occurs because the functions you were using are not included in the list of allowed WordPress/PHP functions. To enable these functions again, please add the following filter to your functions.php file:

function add_extra_hooks( $allowed_functions ) {
    // Add your custom functions here
    $allowed_functions[] = 'is_product_category';
    $allowed_functions[] = 'term_is_ancestor_of';
    $allowed_functions[] = 'get_queried_object_id';    
    
    return $allowed_functions;
}

add_filter( 'widgetopts_allowed_php_functions', 'add_extra_hooks' );

Please make sure to add this filter to your functions.php file before migrating or adding the code again in the Widget Options Snippets page.

I’ve also included a screenshot below for your reference, showing that the code you provided is no longer producing any errors.

We reduced the list of allowed WordPress and PHP functions to help prevent potential vulnerabilities, which is why some functions now need to be manually added through a filter.

Thanks and let us know how it goes on your end.

Kind Regards,
Mej, Widget Options Team
