Topic Tag: CRED API

Problem:
The user would like to send the form notification to the author of the parent post.

Solution:
We can workaround this by hooking into the notification recipients filter. Check this reply https://toolset.com/forums/topic/email-notification-to-parent-post-author-when-child-form-is-submitted-2/#post-1995977

Problem: I am trying to validate a custom field with cred_form_validate, but I cannot validate a specific field. Errors never appear in the form.

Solution: Be sure to include the form_messages field in the Form builder so errors can be displayed. Then use the following syntax to validate a custom field:

function fn_cred_form_validate($error_fields, $form_data)
{
    list($fields,$errors)=$error_fields;
  
    if ($form_data['id']==221) {
        if (empty($fields['wpcf-application-tour-number']['value'])) {
            //set error message for my_field
            $errors['application-tour-number']='Please select tour first';
        }
    }
    return array($fields,$errors);
}
add_filter('cred_form_validate','fn_cred_form_validate',10,2);

Notice that the wpcf- prefix is required in the $fields array, but should not be included in the $errors array.
