Best PHP validation with jQuery
There are a lot of tutorials out there on how to make validation with php/jquery but they are all different... Which one is the best approach? Which one should I use? Which one is up to date? Works in every common browser, etc...

I would like tips... links/tutorials etc on a jQuery validation (plugin) or whatever, that you use and WHY you use it.
