Username Session variable KT_Username(MM_Username)

Using the stock phakt code I couldn't request the session variable KT_Username on subsequent pages, this shows you the easy fix.

Normally when you use a server models login behaviour in ultradev it creates some code which creates a session variable if the login was sucsessful, this can be used to filter things on subsequent pages.

In ASP the session variable is called MM_Username and in PHP it is called KT_Username.

This worked fine for me in ASP but not PHP, I couldn't seem to retrieve the session variable KT_Username on subsequent pages and spent ages looking for the answer, I also noticed that several other people were having the same problem, the answer is simple.

Make sure this code:

<?php
session_start();
?>

is on any and every page where you want to retrieve the session variable KT_Username.

Session Variable Username

Just a wee point, The session variable username is only called MM_Username if you use the stock UD login behaviour, its not generic to ASP, it can be called anything in the whole wide world....

<%= Session("svWellillbedamnedifthisaintmysessionvariableusername") %>

OK????

While this is true the stock restrict access to page and other built in user authentication features do request the stock variable name so it may be wise to use this unless you are doing your own hand coding and want to explicitly create your own session variables and build your own user authentication pages.

Something to be aware if usinh PHP on a Windows platform

If you experience problems that new SID's are being created after using phakt / impakt code then this may prove a solution. - Thanks to Cirstoiu & the Interakt team for providing prompt feedback to all emails sent whilst discovering the solution.

NOTE: This is a Windows problem.

When transmitting session variables from one page to another you have to transmit the session ID first. There are three ways to do this:

1. session ID is transmitted automatically by the server when session.use_trans_sid = 1 (set in php.ini)
2. session ID is store in a cookie when session.use_cookies = 1 (set in php.ini)
3. session ID is transmitted manually by the user in the URL

In my set-up I had set session.use_trans_sid = 1 and session.use_cookies = 0 , BUT under the Windows environment session.use_trans_sid = 1 doesn't work. Therefore when calling session_start in another page the session ID is unknown and another session is created.

To resolve this problem you need to set session_set_cookies = 1

****NOTE****
session.use_trans_sid does not work under windows.
