php - Is server side validation and jQuery Validation both necessary today? -


i have complete jquery validate() validations accross fields in forms, complex , simple validation custom methods.

the question ask considering 2015 , browsers support javascript , have enabled default.

how necessary server-side validation today, , worth it? if so, latest ideal way know few ways such checking post data , outputting error on submit, going few years now.

yes.

  1. javascript in browser can disabled
  2. user can edit javascript code in browser(not reliable)
  3. client side validations save network requests. minimizes load on server. if error, request goes server , respond error.
  4. better user experience
