Thank you very much! This was very helpful for my own project too!

I needed to integrate WP in my own custom CMS because WP can’t handle things that my CMS does. So I have WordPress handling the blog/news part of my site. Instead of my admins having to login twice (in my CMS and WP) they can now login one time in my CMS using the login/session structure of WP applied to my own CMS.

Thanks Man, that worked for me.I wasted my full day googling around and finally got your article. But I am happy that finally it worked for me.. Just one question, you mentioned that WordPress encourages to use cookies and not sessions, any specific reason for that?

Thanks,
Nixy

Well another reason of sessions not working properly could be a plugin.
Yes it is possible if you have two such plugins installed which are starting session at a same time and it can cause them to work improperly.
A few days back i was having the same problem running shopp plugin on my site and i was unable to checkout because of “empty shopping cart” error. there was something wrong going with session variables and it was unable to store cart items then after researching a lot , going through various forums and digging into this problem i came to know after 15 days of continuous frustration that it was my event-manager plugin which was creating all the problem, infact not whole plugin but the em-notices.php file inside classes folder. which was not in my use so what i did is just renamed that file and checked my site again and everything was working perfectly fine
so having two or more plugins starting session at the same time can cause problem in session variable

Hi,
I am looking at various load content (video in this case) “once per session”. Need help. Hopelessly hapless.

I recommend to use

if (!session_id())
session_start();
}

It works for me.
