Undefined index for session data item - El Forum - 12-15-2011 [eluser]Unknown[/eluser] The following bit of code is returning an undefined index error/notice on the first line (discount_rate) but in my understanding, if a userdata entry doesn't exist, then false should be returned. I know that the error is just a notice and that such errors can be hidden, but I don't really see why I am getting the error at all (well, obviously because the entry doesn't exist, but it should be being "handled"). Code: if(!$this->session->userdata['discount_rate']) { If anyone can suggest a way to test whether a userdata item exists, then please share!! Thanks! |
