$_SESSION['user'] undefined problem

[iStriide]

I have this bit of code and when the user is logged out it shows an error and it messes with the way my site looks.

The error is this: Undefined index: user in C:\xampp\htdocs\halobattles\index.php on line 90

 

Here's is an example of how my code looks:

<?php
session_start();

if($_SESSION['user']){

echo "Logged In";

}else{

echo "Normal";

}

?>

 

I want the error to go away when people are logged out.

Perhaps check to see if the array key exists before using it? isset() is what you want. Alternately, you can use empty() which doesn't throw a notice on undefined variables or non-existent keys.

Would I just put "empty()" on the top of the code?

Next time, please check the manual before asking.

 

http://php.net/empty

 

if( empty($_SESSION['user']) === FALSE ) {
  echo 'logged in';
} else {
  echo 'not logged in';
}
