CRED plugin provides an API, making it easy to customize your post or user forms. The API includes hooks (actions and filters) to accomplish specific tasks using PHP code.
When you ask for help or report issues, make sure to tell us all related information about your form and what you want to achieve.
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.
