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,
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
