How do you set your own simple session in Revo 2.2.5+ ?

Hello everybody,

I am sure the answer is simple, or maybe not. In this post, some 2 years ago ..the guy was left as he came .
This is the first time I got dealing with sessions in Revo. I have killed this entire day on the subject, searching and trying.

All I want is to set this to run before any code in the page. I need the page to run within MODx and not without.
I know Revo starts the session and does its own thing, but surely there is a way (that makes sense) to add custom sessions.

This is the only thing stopping me from fully integrating this rather beautiful user chat script
I tried a MODx plugin, but I guess I was not certain how, or what system event to hinge it on.

I'd be most grateful for any positive leads.
Cheers.

That should work in a Snippet just fine. Maybe you should describe what problem you are having with this...

The only thing I can think of that would cause trouble is if the user is in a different domain (maybe due to switching contexts) when the $_SESSION variable is read than the one where it was set.

Changing the username like that could be a problem. I would be inclined to use a different key for storing that, such as $_SESSION['chatuser']. It's always safer to stay away from the key words that MODx uses internally.

You can take care of the subdomain SESSION issue by setting session_cookie_domain in your System Settings (notice the leading "."). http://rtfm.modx.com/display/revolution20/session_cookie_domain [ed. note: sottwell last edited this post 13 years, 3 months ago.]

Thanks for the feedback.
I have used these few days to test my work, and to make sure I am not the one going crazy; alas I am not convinced of the present state of my mind.

Still the same problem: the value does not register; the session, chatusername, remains empty.
Or should I say, the value is not transferred to the chat script looking for it on that page.
Meanwhile, this works perfectly outside MODx: the chatusername is logged and used throughout the whole chatting activity.

@opengeek . I used a snippet.
So, I created a page,
with an empty template
with a call to a snippet that has this content $_SESSION['chatusername'] = "TestUserName";
dumped in complete <html> code

@BobRay . For now, this is within the same domain, and the same context.

@sottwell . I found it, as you suggested, more convenient to use a different variable, so I change it.

Anyone know where MODx starts its session? If as last and desperate resort, I should love to alter it for my needs.
I am not the one to give up on something that is possible, and would deeply appreciate any assistance.

I inject content into the $_session all of the time. It is as simple as:

Snippet call -- note the uncached call <=- probably your issue the first value can get cached into the page and subsequent users will get the same value as the first person if this is cached....

Hello Shawn,

Thanks for the feedback
I already called the script uncached when I integrated the chat with my users; taking care of logged and unlogged users.
Everything works perfectly in my chat file which loads MODx externally.

Since it did not work in MODx proper, I reduced it to what I have above, for diagnostic purposes
$_SESSION['chatusername'] = "TestUserName";

The session id is set but the value is not transferred to the chat script looking for it on that page.
The print_r($_SESSION); or print_r($_SESSION['chatusername']); command, which proves the presence of the value, strangely enough, only works in the snippet where my session was set.

I tried print_r($_SESSION['chatusername']); in a second snippet within the same resource...but no output.
What could be the problem. Why isn't it going global?

Thanks.
