woocommerce_form_field and hidden fields

Question

I\'m trying to add custom fields to the WooCommerce checkout and there seems to be no output for hidden fields.

In woocommerce-template.php, hidden fie

Answer 1

Actually. The last paramatert of the add_filter function is the number of parameters to the function.

The third one is the priority.

add_filter('woocommerce_form_field_hidden', 'wcds_form_field_hidden', 999, 4);

function wcds_form_field_hidden($no_parameter, $key, $args, $value) {

    $field = '

        
        
';

    return $field;
}

This worked for me.
