[solved] Showing Form Validation Messages above the form (instead of inline)
24 January 2012 at 5:11am Last edited: 24 January 2012 5:11am
Hi There,
I would like to have a form that displays all validation messages in one box above the form instead of every message inline under their form-field.
I saw that silverstripe even generates a<p id="Form_TestForm_error" class="message " style=""></p>
paragraph at top of the form, so I wonder if there's a (simple) way to display messages there?
Thanks for any hint!
Regards

$form->sessionMessage('hello world', 'good');
Edit: If you're thinking of disabling js validation, otherwise you'll have some js coding to do, you can get all validation errors from $form->validator->getErrors().

Thx Devlin 4 your answer.
Ok, so I know how to add a message to the form. Now have to look for a way to only add it if validation of the form failed and to get all the (custom?) error messages (from requiredFields?) in there.
I am searching the docs and the net for hors for something like
if ( $form->is_valid() ) {
foreach($form->RequriedFields() as $no => $field) {
messages[] = $field->errorMessage;
}without any results.
Seems like i have to do the whole validation myself / customized just to get the errore messages somewhere else?
Still grateful for any hints
Regads

The form won't call the submit method unless all required fields are correct validated. To do what you want the 'simple way', you can just parse the error messages in your page controller and call it via your template.
class FormPage extends Page{
function showFormErrors() {
$errors = Session::get('FormInfo.FormName.errors');
$_errors = array();
if( !empty($errors) && is_array($errors) ) foreach($errors AS $error) {
$_errors[] = $error['message'];
}
Session::clear('FormInfo.FormName.errors');
return !empty($_errors) ? "<ul><li>".implode("</li><li>", $_errors)."</li></ul>" : false;
}
}Or if have a form subclass you can add your own validation method.
class MyForm extends Form{
function validate() {
parent::validate();if ($this->validator) {
$errors = $this->validator->getErrors();
$data = $this->getData();// edit
$_errors = array();
if( !empty($errors) && is_array($errors) ) foreach($errors AS $error) {
$_errors[] = $error['message'];
}if( !empty($_errors) ) {
$this->sessionMessage(implode(', ', $_errors), 'bad');
return false;
}
}
return true;
}
}* Code not tested

Hi Delvin,
since I also have to do some custom validation I chose the 2nd, subclassing method. Works perfect!
Thanks a lot for saving the rest of my Day!
