Undefined Index

[Xtremer360]

So every time I'm on option 1 the add division form and submit it then it comes up with the message "Notice: Undefined index: option in C:\wamp\www\My Backstage\backstage_libs\division.php on line 13" Why is that?

Because $_REQUEST['option'] isn't defined at the time.

 

Your entire switch should be in between a check for its existence.

 

if (isset($_REQUEST['option'])) {
  switch ($_REQUEST['option']) {
    // rest of code
  }
}

Cool. Works great now however after submission it goes to a white screen. I have it set to go back to list of divisions aka option 1 but it doesn't. Know why that is?
