PHP or JS or Both validation

[Ankur]

I recently created a Registration form for my website, I validated it using JavaScript and it works fine. Was thinking if PHP validation could work better or both. Please suggest.

I've got my first registration project coming up within the next couple of weeks. Writing the actual registration code coupled with an automatic e-mail, subsequent comprehensive registration-and-payment-form page, and numerous insert and update scripts for my registered users' dashboard may take me a few days. At the moment, I'm still structuring the tables for a fairly complex site. According to everything I've learned over the last two years, both is best. JS for speed and client convenience only. Server-side validation for your (and your user's) protection. As I understand it, a monkey could get around js validation. I'm going to try to have the equivalent of three feet of titanium/high carbon tungsten steel alloy protecting my dbases. Actually my registered users will only be allowed to insert and update (via forms) to a "holding" dbase and I'm going to review all material for content before dumping it into the real McCoy myself.
