Session FALSE if not exists - how do i check this? - El Forum - 04-06-2010 [eluser]nevsie[/eluser] Hi All, If i am checking a session for a value, and it does not exist... It logically returns boolean FALSE. The problem i have is how do i check this??? if i check with an isset() - it detects it as a true... if i check for != FALSE it throws a PHP notice for undefined index... the only logical way to check this is by check both isset() && != FALSE like below... but this seems like overkill for something that should be clean cut... can anyone advise? Code: $value = FALSE; Session FALSE if not exists - how do i check this? - El Forum - 04-06-2010 [eluser]danmontgomery[/eluser] If you're using the session library, Code: $this->session->userdata('my_value'); Will return the value if it exists, or false if it doesn't. Code: if($this->session->userdata('my_value') !== FALSE) { If you're not using the session library, and are checking a normal variable like $value, then what you have is technically correct.

And the error: A PHP Error was encountered Severity: Notice Message: Undefined index: monkey I know this gives the correct answer and with error reporting off this will be suppressed - but still not ideal...

It must be something like this: Code: // Monkey does not exist in session!!! mind the () instead of: [] Session FALSE if not exists - how do i check this? - El Forum - 04-06-2010 [eluser]nevsie[/eluser] Ahhhhh balls... i am with you... stupid typo and missed characters on my behalf.
