How can I capture the primary key ID of a record inserted?

How can I capture the primary key ID of a record inserted?

I've used DA to create an insert and detail page, and it works fine, but I need to filter the recordset based on a session ID rather than pass it through a URL. So, my question is, how do I capture the primary key (in my case 'b_id') of a record that has just been inserted and use it as my recordset filter?

I don't want to use a URL variable because the URL can be manually changed displaying other data

From my knowledge of how DA works, it creates a session as a record is inserted, and I am assuming that it is this block of the insert code that does it:

$_SESSION[$WA_sessionName] = mysql_insert_id($WA_connection);
if ($WA_redirectURL != "") {
$WA_redirectURL = str_replace("[Insert_ID]",$_SESSION[$WA_sessionName],$WA_redirectURL);
if ($WA_keepQueryString && $WA_redirectURL != "" && isset($_SERVER["QUERY_STRING"]) && $_SERVER["QUERY_STRING"] !== "" && sizeof($_POST) > 0) {
$WA_redirectURL .= ((strpos($WA_redirectURL, '?') === false)?"?":"&").$_SERVER["QUERY_STRING"];
}
header("Location: ".$WA_redirectURL);
}
}

Which is added to the code a dozen lines or so above it:

$WA_redirectURL = "booking-detail.php?b_id=[Insert_ID]";

My guess is that this created the session visible in my Bindings panel which in my case is called: WADA_Insert_tbl_bookings.

I've placed this session in my recordset, but it's not working. It's not picking up the record and displaying it.

Basically, in the advanced version of the recordset creator I have replaced $_GET['b_id'] which is setting the URL parameter and trying to populate with $_SESSION['WADA_Insert_tbl_bookings'].

Am I doing this wrong?

Make sure you have:

@session_start()

above the code so that the session variables are available. If you attached a copy of both pages I could check to see if you had a typo, but your logic is sound.

Yeah, I have @session_start() at the top of the page code, and to ensure I had the correct spelling of the session, I first inserted it onto the page via the binding panel, then cut it and pasted it in to the advanced recordset panel, but it just wouldn't work.

What's really weird though is how I managed to create a session from the session -- I just copied the name and added 2 on to it like so:

@session_start();
if($_SERVER["REQUEST_METHOD"] == "POST") {
$_SESSION["WADA_Insert_tbl_bookings2"] = "".$_SESSION['WADA_Insert_tbl_bookings'] ."";
}

This worked for some reason, whereas it just wouldn't before. The only difference is that this sits directly under the insert code and although being fed by the insert, it is separated by my fumbled attempt to get it working. So, as it is working, I'll leave it as it is.

Thanks for responding though Ray. Always appreciated.
