Validation rules custom field

Hi,

I got a review form displayed on the product category archives page.

I only got 3-4 products per category then I did add a custom select field to let user choose the product he is reviewing.

site-reviews/config/forms/submission-form is working very well ??
site-reviews/submission-form/order no problem either

I do assign the product id to the review with
site-reviews/review/created and it’s working perfectly.

But when I try to filter the easiest to make the field required, it doesn’t work. I tried to filter on a custom select and a custom input text, there is no class ‘glsr-required’ added, and I can submit the form with an empty field…

Here is my filter :

add_filter('site-reviews/validation/rules', function ($rules) {
    $rules['e-books'] = 'required';
    $rules['test_input_text'] = 'required';
    
    return $rules;
});

Where the key is the same as the $config array defined in the ‘site-reviews/config/forms/submission-form’ filter…

Do you have any idea ?

Thank you very much for your help ??
