Use SESSIONS or COOKIES. The value of each field would come from the SESSIONS or COOKIES, if empty then the field would be empty.

or jsut run the check in the same page.

PHP Code:


			
<?php



$errors = array();



if (isset($_POST['submit'])){



    $name  = $_POST['name'];



    $email = $_POST['email'];



    $phone = $_POST['phone'];



    $question = $_POST['question'];



    



    if($name == ''){



        $errors[] = 'Please enter your name.';



    }



    if($email == ''){



        $errors[] = 'Please enter your email.';



    }



    if($phone == ''){



        $errors[] = 'Please enter your phone number.';



    }



    if(count($errors) == 0){



        //if no errors run this code you enter here.



    }



}

This will check the form and if they miss a field it will show what they missed. This is a pretty straight forward way to do it. Just add your code you want to run on success.
