Fields validation by server validation

Hello,

I have to set a form with a compatibility with IE7 so I'm obliged to have a server validation instead of JS validation. My question is how I can test a validation for field (french zipcode) if I want this field to be 5 digits (no more no less).

With JS I set a custom a Load Javascript on Load with this code :

function cpostalCheck(el){
  if ( !el.val().match(/^([0-9]{5,5})$/) ) {
    return false;
  } else {
    return true;
  }

With a server validatin how can I do it ?

Thx for answers

Hello erix,
I'm not a Chrono professional, but after checking your new post, I think that the following links may help:
Handling serverside validation errors . . .
How can I add Auto Serverside Validation?
How do I use Custom Serverside validation?
How can I run Auto and Custom Serverside Validation together?
P.S: I'm just an automated service😉

Thx calculus00 to submit theses links but I have already read them and I didn't find the answer in tit😟

Hi erix,

The code has to be translated into PHP from JavaScript. It will be something like this:

<?php
if ( isset($form->data['cpostal']) && preg_match('/^([0-9]{5,5})$/', $form->data['cpostal']) === false ) {
  return false;
} else {
  return true;
}
?>

Thx Bob,

Ok I understand I have to put this code in a custom code but my question now is to know where I have to put this custom code : in server validation/On success ? Before Server validation ?

In v5 you can use Bob's code in an "Event switcher", and return the event name instead of true/false.

Here is how to use the event switcher:
