How to default the channel when user hits a page?

by **homerlex** » Wed Jan 12, 2011 5:57 pm

I'm new to this and playing around with 1.3. I want to have a page that forces the user into a specified channel.

I thought perhaps something like this would work:
$params["channels"] = array($_GET["channel"]);

The problem is that it always defaults the user to the first channel created. For example:

- User 1 hits chat.php?channel=room_1. He is properly put in room_1.
- User 2 hits chat.php?channel=room_2. He is also put in room_1. Is there a way to just get him to automatically be put into whatever name is specified on the channel param?

Thanks!

OK - I went though the thread an though I followed it properly. I set up a test (see code below) and it seems to redirect the the specified channel on the user's first hit. However, if that same user tries to hit the join page with a different channel name he is still joined into the first channel.

Example:

User first hits /join?channel=first_channel. He is redirected to chat and is joined into first_channel. Then, the same user hits /join?channel=second_channel. He is redirected and again is put into first_channel.

I'd like to be able to put users into different channels based on where they are on the site.

What am I doing wrong?

join.php:

Code: Select all: <?php session_start(); $_SESSION['url'] = $_GET["channel"]; // retrive ?channel= and store in url variable echo "Connecting to channel: ". $_SESSION['url']. " . . ."; // display session variable ?> <head> <meta HTTP-EQUIV="REFRESH" content="0; url=/chat.php"> </head>

chat.php:

Code: Select all: <?php session_start(); require_once dirname(__FILE__)."/src/phpfreechat.class.php"; $params = array(); $params["title"] = "My chat"; $params["nick"] = "guest".rand(1,1000); // setup the intitial nickname $params['firstisadmin'] = true; $params["serverid"] = md5(__FILE__); // calculate a unique id for this chat $params["debug"] = false; $params["channels"] = array($_SESSION['url']); $chat = new phpFreeChat( $params ); ?>

I found that resetting the session each time solves the problem.

New join code:

Code: Select all: session_restart(); $_SESSION['channel'] = $_GET["channel"]; . . . function session_restart() { if (session_name()=='') { session_start(); } else { session_destroy(); session_start(); session_regenerate_id(); } }

The problem with the above solution is that I am also controlling the nickname. The same redirect solution works OK with the nickname on the url until I hit the join url again (to change rooms) with the same nickname on the url.

When I do this I get the popup that says "Nickname is already in use"

Is there any way to disable this check (since I will be controlling the names used anyway)?

Just a note: we'll eventually have a more secure mechanism to control the nickname so no one can just manually pass in whatever they want :-)

I think the system actually uses nick as the identifier for messages and what have you (there may be an id as well, but I think it's just nick), so in short, no, you couldn't disable it without creating a potential for huge problems.

However, I'm not certain of this. Other users are welcome to chime in with a more certain answer.
