thanks for reply...

ok, one think i just want to know how much client side validation is unsafe as compare to server side validation, and in which case, or on both we can rely with satisfaction....

Server side validation is more stronger than client side.

Client side validation stops the user from having to resubmit the form for every mistake they make. It does not, however, validate Anything as far as you are concerned. Everything should be checked server side, especially SQL injections.
