Undefined variable: _SESSION when sending variables via post through JavaScript trigger

Question

In my index.php file I call session_start() and set a couple of session variables. In a second PHP file I would like to access these session variables.

Answer 1

I had this problem and tried different ways and finally found a solution :

PHP is case sensitive, Use $_SESSION instead of $_session in all php files.certainly It works . Example :

";
echo $_SESSION["s2"]."
";
?>
