[#4414] Server side validation

Hi Kyle,

I need to write up a server side validation so as to avoid non-english characters during registration. We deal with education and certifications and issue certificates in english.

I do not want this validation in client side as I have to re-perform this on server side too. Can I do this without modifying core CB files and just using CB autoactions? i.e Before registration, add a php validation to check the $_POST for any non-english character and then raise error message to user, just the way CB display serverside validations such as email already registered, captcha invalid.
I have seen CB code where CB making call to before,after triggers and does some status check but I am not sure whether from auto actions it is possible to pass validation errors back to framework so that it can stop processing and display validation message to user. If possible then how and in what structure I need to pass validation error back to framework.

Thanks,

You can probably just add custom regex valiation to your field by editing your field within CB > Field Management. CB Auto Actions is not really suited for validation. It's designed to not interfere with normal processes so I doubt you'll be able to stop registration.

Thanks Kyle. Custom regex field validation is all I need here as it is working as server side validation.

Hi Kyle,

I see a difference when validations happens for some field. There are few fields which support even client side validation + server side validation where as firstname, middlename and lastname only supports server side validation for regex. Why firstname,lastname only server side. Point is on few fields, as soon as user enters text, validation message displayed in case it is incorrect. So for some field user will see message after submitting request. Since framework allows serverside and client side validation for regex so I am picking it both.

Thanks,
Amit

Name and Username are stored to Joomla so Joomlas validation needs have priority over CBs for those fields. It does do client side validation, but only to ensure characters against Joomlas validation aren't included. The custom validation you can supply to the field happens server side for these fields. I can probably get this implemented and working for CB 2.0 though as it just needs another or case to the jQuery validation.

Ok, implemented this for CB 2.0.

Username and Name fields will support client side validation in CB 2.0.
