It sounds like that datum is missing because it's not being sent. Steve is incorrect in suggesting that $_POST['submit'] will be populated with data from an HTML input of type "submit". To achieve the effect he is describing, you would need to add name="submit" to that input. None of the keys of $_POST are magically populated. If your request doesn't submit a variable named "submit", there will be no such key in the array. -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP-DB] Value of $_POST['submit']
Hi Steve, He's using Ajax, so some variant of the XMLHttpRequest Javascript object on the client. It may not be obvious which method is used when the data is sent. Now that I think of it, printing $_SERVER[REQUEST_METHOD] should let you know which one is being used. hth.

Re: [PHP-DB] Value of $_POST['submit']
Hi Ron, What's your Javascript client-side code to invoke the PHP-script? You may need to switch to $_GET[] instead of $_POST...
