I need to allow the form user to fill out the form using alpha numeric characters only.
After reading what I could find this my first attempt to use preg_replace.
This works but I need to make sure I am validating the user form input.
Have I missed any thing?
<?php $find = strip_tags(trim($_POST['find'])); $find = preg_replace("/[%|<|>|!|?|#|*|@|(|)]/", "", $find); ?>
