session variable not carrying

I've used the webassist mysqli recordset builder to retrieve a record. Then I assign one of the record's column values to a session variable. I know that the variable is properly assigned because on the same page with the mysqli UPDATE function/form, I show the variable successfully. After the user completes the record UPDATE and is redirected to a secondary page, the session variable is suddenly empty. Is there something in the webassist recordset builder (set to pull the record based on the session variable value) that's killing the value on the second page???

try starting the session on the page that is not showing it. add the following at line 1:
<?php @session_start(); ?>

if the problem persists, I'll need to troubleshoot directly, see the private message section.

the session_start is already enabled in the connection code. If I add this, then I get a message that session support is already enabled and that particular instruction I've added will be ignored. Perhaps this is part of the issue, I'm trying to assign a session variable via this method, perhaps you can correct me?

$_SESSION['GID']=$GuestInfo->getColumnVal("GID");

where is that code added?

is it on the update page?

perhaps code so the session is only set if the recordset has a value:

if($GuestInfo->getColumnVal("GID") != "") {
$_SESSION['GID']=$GuestInfo->getColumnVal("GID");
}

The webassist INSERT code includes this instruction: $InsertQuery->saveInSession("GID");

..and when I build an INSERT page pointing to the same secondary page, the record is pulled based on that session successfully. I'm just trying to do the same thing with an UPDATE.

The GID value is already in a different recordset ($GuestInfo) on the update page, used to populate the field values with the existing data so the user can decide what needs to be updated. It's just when the redirect happens after UPDATE, the session doesn't exist.

>>>>More Info: I wanted to share that on the UPDATE page, after the $GuestInfo recordset is pulled, that's where I was trying to assign the GID (from that recordset) to a session variable so that on the final page, that same recordset could be pulled and displayed again - showing the update.

did you try the if statement i provided?

if the problem persists, I'll need to troubleshoot directly, see the private message section.

info included in private statement

By the way, I did write a 3-page process as a simplified version of what I'm trying to do, and it all works perfectly. This suggests there's something on the edit-guest page that's getting in the way.

I added the ifs statement to the edit-guests.php page as i had suggested, and it fixed the problem.

Thanks for the help, I'll take a look.
