Undefined Arrays

[Niss3]

I'm using $_POST[] and $_SESSION[] arrays for a homemade quiz.

When I turned display errors on in my PHP file I got alot of "undefined array" errors for those ones.

Is there anyway I can allow those two variables to be undefined? Like, everything is working fine and I've accounted for them beeing NULL at times.

You'll have to show us the code where the errors are pointing.  Be sure to clearly identify them to us.

You should ensure they are not undefined before attempting to use them.

In the case of $_SESSION, call session_start() at the head of any script requiring $_SESSION.

In the case of $_POST, check if data was posted to the script

if ($_SERVER['REQUEST_METHOD'] == 'POST' ) {
    // safe to use $_POST here
}
