Module Development in WHMCS

Hello,

I am developing a module for WHMCS.

It seems pretty easy so far, but what I'm not understanding is whether there are any built-in functions to make things easier.

For instance, form validation. If I place a form in my module, is validation all my own responsibility, or are there helpers and such to make things consistent?

WHMCS has documented a few functions but not all of them and none concerning form validation.

Here is more information on the functions that are documented:

Are there any best practices, or at least other modjule developers who can say how they did their own form validation?

After developing for Drupal, WHMCS is a very different experience.

I either perform form validations manually via regex or I use a form validation class. This one has worked fairly well for me in the past:

It would be nice if WHMCS would document their form validation class then we could use it within custom modules.

Yes, totally agreed.
