There is session_start on every page if i define veriable like $_SESSION="test" it passess all 3 pages but the data generated in the form is lost. Please help!

Answer 1

$_SESSION="test" is overwriting all of your session data.

Instead you should do what you are doing in other places and use $_SESSION['test']="test" .

This will put a new item into your $_SESSION array instead of overwriting all session variables.
