SMF check if the user is logged on

[Laloeka]

Hello community,

I was searching how to do this, but I couldn't really find it anywhere. My goal is to make a chat-window in the theme template, which only shows when the user is logged on. That by itself isn't really hard to do.

My question is: How can I check if an user has logged on to the forum from another PHP file (for example: chat.php), where the chat messages are sent to, and are received by the chat-window in the forum page. I know it's possible, but I'm not sure how.

Can anyone help me with this?

Thanks!

Hi Laloeka, welcome to SMF!

Have you already included SSI.php in that PHP file?

If so, do this for every user:

Code Select Expand

loadMemberData(userid);

And don't forget to global $user_profile.

Then, you can use this:

Code Select Expand

$is_online[id] = $user_profile[id]['is_online'] === 0 ? false : true;
Replacing id with the user ID.

Then you can use $is_online[id] to check if an user is online.

That's great, thanks!

Ehm shouldn't this be in coding discussion?

I already reported it to the team, I think it gets moved in a while.

If so, do this for every user:

Running 2 or maybe 3 queries for every user, that's nice and efficient, isn't it? Pass an array of ids to loadMemberData rather than an individual member id at a time, so you only do one query for all of them.

Or you could query the {db_prefix}log_online table and get the id_members of all online members directly from there...

Oh, sorry, forgot about that. Yeah, that's indeed more efficient

I have another question extending this one, so I could continue here:

I want to check if a user is completely banned, or partially banned (i.e. not allowed to post), and possibly if it's permanent.
