Someone said: "The isset() function is very helpful to find if a form field was submitted as blank. I could give an example but I think somebody alreay did in here. My point is that isset() and empty() are redundant but they do allow you to program in error_reporting(E_ALL) without warnings or notices, which usually means more secure scripts..." Responce: This is incorrect. If a form field is left blank when submitted, isset($_REQUEST["field"]) will return true b/c there is a blank/null in the field. However empty($_REQUEST["field"]) will also return true b/c there is a blank/null in the field. isset is not helpful in this case. empty is extremely helpful. ---- Manual Page -- http://www.php.net/manual/en/function.empty.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+42914 Delete -- http://master.php.net/manage/user-notes.php?action=delete+42914&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+42914&report=yes Search -- http://master.php.net/manage/user-notes.php
