Sessions

I am looking into the modSession class, to see if it might be used to store session data for custom modules. Unfortunately, this is still missing from the documentation, so a couple of questions

What is the relation between modSession and modSessionHandler? I read some hints to cache in the documentation, but I can’t see anything concrete there.

Can I add custom fields to a session? If yes, what is the preferred way of doing this?

It seems the session data is stored JSON encoded. Is there any API available to pack/unpack this?

I noticed the session_handler_class setting. What are your thoughts on using this to extend modSession/modSessionHandler?

I’m probably misunderstanding your question, but unless you have special needs, you can save just about anything with:



and retrieve it with

Yes, I was actually looking for something a bit more than the $_SESSION array, although it is mostly exploratory at the moment. Just trying to get an overview about the options in order to be able to choose what to use.

Hmm. Looks like I might be misunderstanding the concept totally here. I just noticed that the functions in session_handler_class is registered by session_set_save_handler(), which would imply that $_SESSION is actually the only thing I need to care about. So simple...

That’s what we aim for (though it doesn’t always turn out that way).

It might be a god idea to get something into the documentation about this. It is one of the things that have been done really well in Revolution, so it can’t hurt to point that out

I found this by Googling: MODx sessions

FYI, that article is valid for Evolution only. Revolution session handling is completely different and uses a custom database session handler.

Definitely. This will be a focus post-RC1 release.

I have provided various $_SESSION and environment information on my site.
