Re: SESSIONS - SOLVED

Bastein - Correct 100%. I feel rather stupid. A POST or GET will cause session variables to be transferred. From another post to the UNIX list, this works..... <script type="text/JavaScript"> <!-- window.open("HandleFood.php","_self") //-->\ </script> and the SESSION variables transfer. Sorry for bothering you with such trivia. Ethan -- On 01/01/2015 11:21 PM, Bastien Koert wrote:

Ethan, As was explained in another post, sessions DO NOT WORK when you call shell_exec because the browser the user is using holds the session cookie WHICH IS NOT AVAILABLE during a shell_exec This is totally expected behavior. If you need to call the second script via a cron for example, no session variables will exist. Your script would have to generate those values (perhaps from a database call to some table) to have those available in the script. If your first script is calling shell_exec ( calling shell_exec from a script to another script in processing a browser call is just weird) then you would have to pass the session values you need in the shell_exec call as parameters.

    Dear List -

    I can make it work, but I do not know why???

    I have two scripts, HandleWeight and HandleFood.

    I call HandleWeight from a form ...

    echo "<form method= 'post' action='HandleWeight.php'>";
    echo "<center><strong><input type = 'submit' value= 'WEIGH'></strong></center>";
    echo "</form>";

    and the session variables appear in HandleWeight.

    I call HandleFood with a shell_exec,

    $output = shell_exec('php HandleFood.php');

    and the variables do not appear in HandleFood.

    If I call it from a form, the variables appear.

    What is going on??

    TIA

    Ethan

    cookies and

stuff shouldn't session_start go first?
