RE: [PHP] Dynamic Array Index using Variable

You could use the isset() or the empty() functions. http://us3.php.net/manual/en/function.empty.php http://us3.php.net/manual/en/function.isset.php But do you want to check all the fields that are being submitted or just specific ones that you set in the $reqfields array? If you want to check all the submitted fields just run through the $_POST or $_GET arrays, depending on your form method. jay -----Original Message----- From: Chris Lott [mailto:chris.lott@gmail.com] Sent: Mon 1/9/2006 2:31 PM To: PHP General Mailing List Subject: [PHP] Dynamic Array Index using Variable I want to do something like this to check if a variety of submitted form fields (crn, instructor, etc) have any value in them: $reqfields = array('crn', 'instructor'); $errorflag = 0; foreach ($reqfields as $field) { if ($_REQUEST[$field] == '') { $errorflag = 1; } } But I can't quite get the syntax right... help?? c -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
