cookies and forms

[Anon]

I have one php form that links to another php file that processes the info from the first form. How can I have it set to save the same processed information in a cookie, so that when the user comes back to the original form it checks for the cookie and if it exists, loads the information so they don't have to type it in again?

You can set teh cookies using the

setcookie()
http://www.php.net/manual/en/function.setcookie.php
function. You later retrive the info you stored on the cookie by using

if(isset($_COOKIE['var_name'])) {
// Load the Info to the text box
} else {
// No cookie Info was found
}
