change chatroom title on the fly?

[mak2k]

I stumbled upon this site while looking for intro about PHP and AJAX (just learned how to use it today.. and it's freaking cool stuff!!!) and i have to say i'm INCREDIBLY impressed! I was looking for a chatroom for my online community. So far, i'm happy with this.

I was wonder if it's possible to change the chatroom title on the fly? I know i can write my own command, but i was wondering how i can do it? I know i can change it in index.php with the params["title"] but that requires me to rehash the page. Also, what is the maximum amount of people that can be on this chat at a time?

Thanks

Ideally if you could do that, then you could change the title to notify people of a new message similar to googletalk on googlemail

The thing I have been looking at is closing the chat window then opening it back up with a new title.
Of course that means a new chat room too. Now I don't know that is what you are talking about.

I'm working on something like this as well...
i have a command class, and an template hack, but I'm missing parts.. I just started learning ajax

Code: Select all

<?php
//topic.class.php

require_once(dirname(__FILE__)."/../pfccommand.class.php");

class pfcCommand_topic extends pfcCommand
{
  var $usage = "/topic {message}";

  function run(&$xml_reponse, $p)
  {
    $clientid    = $p["clientid"];
    $param       = $p["param"];
    $sender      = $p["sender"];
    $recipient   = $p["recipient"];
    $recipientid = $p["recipientid"];
   
    $c  =& pfcGlobalConfig::Instance();
    $u  =& pfcUserConfig::Instance();
    $ct =& pfcContainer::Instance();

    if (trim($param) == "")
    {
    $fh = @fopen('topic.dat', 'r+');
    $topic = @fread($fh, filesize('topic.dat'));
    fclose($fh);
    $ct->write($recipient, "*topic*", $this->name, "current topic: [i][u]".$topic."[/i][/u]");
    return;
    }
    $msg = phpFreeChat::PreFilterMsg($param);
    $ct->write($recipient, "*topic*", $this->name, $u->getNickname()." changes the topic to: [i][u]".$msg."[/i][/u]");
    // Write out the topic data
    $fh = @fopen('topic.dat', 'r+');
    $topic = @fread($fh, filesize('topic.dat'));
    if ($topic == $msg."n"){
    fclose($fh);
    die(0);
    }else{
    @fclose($fh); // if it errors, then the file doesn't exist, and the stream was never open
    $fh = fopen('topic.dat', 'w');
    fwrite($fh, $msg."n");
    }
    fclose($fh);
  }
}

?>

One problem is, I cannot seem to figure out away to only allow admins or operators access to change the topic.

Now for the template hack (default)

replace this:

Code: Select all

 <h2 id="pfc_title"><?php echo $title; ?></h2>

with this:

Code: Select all

<?php
    $fh = @fopen('topic.dat', 'r+');
    $topic = @fread($fh, filesize('topic.dat'));
    fclose($fh);
?>
<h2 id="pfc_title"><?php echo $topic; ?></h2>

The problem is, I'm just learning ajax, I am unsure how to have this piece of code refresh w/o refreshing the whole page.

Hopefully someone with knowledge will step in and help out..
