redirecting some values from one page to other in php

I am using header method for redirecting to another php file.I also want to pass some variables to the redirected file. for example: file1.html---- where i have a dropdown menu. the user selects the options... this form has a action to file2.php file2.php--- i get the values of the form by using $_POST. In this file i will do some processing on data and redirect to file3.php file3.php---- here i need the user select menu items. i think i can use require_once(file2.php) in file3.php and get the values.But i want to get the values selected by user from html form. Thanks for the help. babu --------------------------------- Yahoo! Messenger NEW - crystal clear PC to PCcalling worldwide with voicemail
