Re: [PHP] PHP Syntax Help - Check?

if you do the redirection with header('Location: /mypage.php'),
setting a variable on formcheck.php is not enough.

if you modify the header('Location: /mypage.php') to..

header('Location: /mypage.php?my_id=5')

it will take the variable to mypage.php as $_GET['my_id]

you can not expect a variable value set in to $_POST array to reflect
on a totally different page without making it a form post (aka use of
proper headers).

i guess, it's time to you to read about session_start() method and the
array $_SESSION available in php :)
