Display message in event switcher event

Hi people. I've a event switcher with custom code that verified some field like in submit event:

<?php
if ( isset($form->data['field1']) && $form->data['field1'] ) {
  if ( strlen($form->data['field1']) < 8 || strlen($form->data['field1']) > 10 ) {
    $form->validation_errors['field1'] = "Error!";
    return "fail";
  } else {
return "success";
}
}
?>

but error is never show.
In a event switcher fail i've insert event loop that point to load
I tryed to insert a display message but never show.

Nothing help for me?

Hi Zampieri,

instead of:

$form->validation_errors

please use:

$form->errors

YEEESSSSSSS I finisched my first Chronoforms V5! Thank's.
A little question, but where I found complete documentation with information like above?

Here on the forums or on the FAQs (tutorials), we don't have a full documentation for every feature.
