Are you certain this is happening on text fields? Typically text fields, password fields and textareas allways set a key, and no value of blank. Ie: $_POST['FirstName'] = ''; Select boxes should always have a value set. Check boxes are only set IF the box was ticked. What I'd advise is that you make a quick form and test this out -- perhaps it was only checkboxes that were sometimes not being set? > any ideas.

Write a SMALL test script, test it, and if it ain't working, post the code :) Justin -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
