CHAPTER 14 Server Side Validation::

When we submit a form the form should be validated.This means we should apply a rule to check that the mandatory fields are not empty and the value entered is in correct type.

For the above form we will add an action in process.php

if(isset($_POST['submit']))

{

if($_POST['name']!='' &&

$_POST['number']!='' && $_POST['email'])

{

code to be executed }

else

{

redirect to previous page }

}

The code above checks if the fields contain some value or not.If the value is not set for any field then the guest gets

redirected to the form page.
