You have to pass the parameters when you add your filter.. Something like

The third parameter in add_filter function is the numbers of parameter that the filter receive.

The last parameter is the priority...

add_filter('woocommerce_form_field_hidden', 'my_form_field_hidden', 4 , 15);

Now you have to set the paramteres in the filter function.

if ( ! function_exists('my_form_field_hidden') ) {

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

        $field = '

            
            
' . $after;

        return $field;
    }
}

I hope it helps
