Note Submitter: isis at frostbyte dot fdt dot net ---- I don't know if this has been mentioned before, but I found an interesting use of variable variables. They are great for checking required (especially when you have about 15 of them). You create an array with the required variable names from the form and then loop through the array checking for blanks, NULLS, etc. ex. <?php $required = array("username", "password"); for ($i = 0; $i < count($required); $i++) { if (($$required[$i] == "") || (!$$required[$i])) { echo ("Umm... we need $$required[$i]"); } } exit(); ?> Just a thought if you have large forms. Still need to figure out how to get it to work with mutliple input variables (although it should, I have never tried). frostbytten
