In the Classified's site I have set a custom field "mileage" as required.
However, in the CRED submission form, this does nothing.
It still accepts a blank field and then the listing throws an error warning message.

Why doesn't this work?

Is there a workaround such as setting a custom validation in the functions.php file that we can use?

Hello,

Q1) Why doesn't this work?

The problem you mentioned above is abnormal, in case it is a compatibility problem, please try this:

1) deactivate other plugins and switch to wordpress default theme, and test again

2) If the problem still persists, please provide a database dump file (ZIP file) of your website in below private detail box, also point out the problem page URL and CRED form URL, I need to test and debug it in my localhost, thanks

Q2) Is there a workaround such as setting a custom validation in the functions.php file that we can use?

Yes, you can follow our document, use CRED filter hook to add your custom validations:

https://toolset.com/documentation/programmer-reference/cred-api/#cred_form_validate

This hook provides custom validation for form fields

In this example:

add_filter('cred_form_validate','my_validation',10,2);
function my_validation($error_fields, $form_data)
{
    //field data are field values and errors
    list($fields,$errors)=$error_fields;
    //validate if specific form
    if ($form_data['id']==12)
    {
        //check if featured image exists
        if (empty($fields['_featured_image']['value']))
        {
            //set error message for featured image
            $errors['_featured_image'] = 'Missing featured image';
        }
    }
    //return result
    return array($fields,$errors);
}

I want to check that each field is NOT empty.
Where can I find the machine readable field ID ? e.g. '_featured_image'

[Luo Yang]

If the field is setup by CRED shortcode [cred_field], for example featured image:

[cred_field field='_featured_image' value='' urlparam='' output='bootstrap']

As you can see, it is attribute "field", which is the "field ID" you are looking for.

You can edit the CRED form, and find the field slug(ID) in the shortcode [cred_field].
