Question

I have a form where I insert a record and the ID (Primary key is Auto increment).
How I can show the ID in the next page after submit. I tried to echo mysql_insert_id(); in next page but didnt work:

<?php echo "Your refrence number is = ". mysql_insert_id(); ?>

Friend, Let’s see your issue this way. You have two pages A, and B. You insert data to the database in page A and get the last insert id with mysql_insert_id(); Now the issue is you want to use this in page B. I can propose you 4 ways. but I will explain you session base way since I think it is the best solution for you.

1. POST
2. GET
3. Cookie
4. Session

Ok In your page A top of your page you write session_start(); remember it should be the first line. Once you get the last insert ID in page a you create a session variable.

$_SESSION["lastID"] = mysql_insert_id();

And in page B also you initiate the session as you did in page A. Then you can simply get the last ID using.

$lastID =  $_SESSION["lastID"];

Hope you understand.
