Thanks Rod!
Unfortunately, it's still not working. Here's what I tried:
Smarty template/web page "view_by_permalink.php":
$smarty->assign('sessionId', session_id());
$smarty->assign('sessionName', session_name());
<img src="captcha2.php?{$sessionName}={$sessionId}" alt="validation string"
/>
captcha2.php:
session_id( $_REQUEST['PHPSESSID'] );
start_session();
$_SESSION['captcha'] = $cmntPass;
Using error_log(), I determined that in captcha2.php, $_REQUEST['PHPSESSID']
is the correct session ID. But something isn't right because if I stick
error_log('hello world');
in captcha2.php before start_session(), the message appears in my error log.
But if I stick it in after start_session(), it doesn't appear. So PHP seems
to be very unhappy with the start_session() line.
Needless to say, 'captcha' is an undefined $_SESSION index in the receiving
form.
I'm really on ground here. I'm reading, but there's enough documentation to
drown in.
Have any idea on how to proceed?
Pete
