I'm using the cred_form_validate function to require a user to select at least one taxonomy term on a front end post CRED form. I got the function from another support thread. The function is as follows:-

// Use to make it required for user to select at least one member category when adding new member
function member_require_category($field_data, $form_data) {
 
    // Split $field_data into separate $fields and $errors
    list( $fields,$errors ) = $field_data;
      
    // validate specific form
    if ( $form_data['id'] == 121 ) {
 
        // check at least one of required taxonomies set
        if ( empty( $fields['member-arts-culture']['value'] ) && empty( $fields['member-clubs-leisure']['value'] ) && empty( $fields['member-community']['value'] ) && empty( $fields['member-visit-dereham']['value']  ) ) {
 
            $errors['member-arts-culture']= 'You must choose at least one category';
        }
    }
 
    return array($fields,$errors);
}
add_filter( 'cred_form_validate', 'member_require_category', 10, 2 );

The function works correctly but the error message is a bit confusing. It reads:-

'The post was not saved because of the following problem:

Members-Arts-Culture: You must choose at least one category'

So I want to remove the 'Members-Arts-Culture' from the error message. Is this possible?

I tried changing return array($fields,$errors); to return array($errors); but the error is not reported at all.

Your advice would be appreciated.

Regards

Dear Robert,

There isn't such a built-in feature within CRED, if you change the field slug, it will conduct unexpected result as you mentioned above: the error is not reported at all.

As a workaround, you can create another custom field, for example "show-error-field", put it into the CRED form, and hide it with CSS codes, use it in your PHP codes, replace this line from:
$errors['member-arts-culture']= 'You must choose at least one category';

To：
$errors['show-error-field']= 'You must choose at least one category';

Hi Luo

The wordaround worked perfectly. Thanks for your help.
Please add my vote to getting the facility to make taxonomies a required field in Toolset added as a new feature.
