Hi I have uploaded and tested the sessionTest.php file.
When I click the first link the URL changes to the following:
http://www.hackneyhydroponics.co.uk/demo/sessionTest.php?test=test
When I click the second link the URL reads:
http://www.hackneyhydroponics.co.uk/demo/sessionTest.php
I think the sessions are working as I have set a session on the log in page to capture the username from the DB after log in and display it on the log successful page, and that works fine.
Thanks for your help.
