Should user input data validation occur server-side or client-side? Why? ..

Answer / manish singh(amalga fusion)

user input data validation can occur both side means client
side as well as server side. but generally validated on
client side because in this validation no any sever
resources used for validation. So it provides less
overhead on server and application performance become fast
rather than server side. if we validate user input data on
server side every time data check on server so the
performance of application become slow down.

Answer / zaw

Client side validation such as javascript can be bypassed.
It is not secured at all. But it can be used to provide
quick feedback to the users. For example, if the user enters
invalid username and jump to another field, show an error
message quickly with client side validation.

Sever side validation protect against against the malicious
user. Using both techniques can provide secrue, quicker
validation and compatibility .
