  Tutorial: PHP Form Processing Form Validation With PHP Tutorial

This tutorial explains how to validate HTML form on server side using PHP plus client side form validation using Javascript to make your form more user friendly

Tutorial Details:

Validation With PHP

Whenever you make a form you should not leave it alone without any form validation. Why? Because there is no guarantee that the input is correct and processing incorrect input values can make your application give unpredictable result.

You can validate the form input on two places, client side and server side .

Client side form validation usually done with javascript. Client side validation makes your web application respond 'faster' while server side form validation with PHP can act as a backup just in case the user switch off javascript support on her browser. And since different browsers can behave differently there is always a possibility that the browser didn't execute the javascript code as you intended.

Some things you need to check :
empty values
numbers only
input length
email address
strip html tags
