Invision Power Board (IPB) Integration?

[Ryan]

Has anybody tried integrating this with IPB message boards, similar to how there's a VB and phpBB version? I'm not too code savvy, but I'm willing to give it a go since this is by far the best free chat application I've stumbled across yet. I figured I'd ask if somebody else might already have figured out what to put in /lib/custom.php before I spent a few hours working on it myself.

[Ryan]

Phil, thanks for the tip, but I actually use TextMate on a Macbook. Haven't touched Notepad in years :)

I've got a copy of Coda somewhere around here though. I'll try using that and seeing if it helps any.

[Ryan]

I take it by the silence that it's a negative on an IPB integration? I had a further look at the code and realized it's a bit above my skill level.

I'd be willing to pay for somebody to integrate this with IPB, hint hint :D

I just completed th AJAX Chat integration with IPB :

First download IPBWI (Invision Power Board Website Integration), it's easy to find and edit its config file (hope you can do this by your own).

Then for AJAX Chat :

1) edit /lib/custom.php
----------------------------------------
// Include custom libraries and initialization code here
require_once('../ipbwi/ipbwi.inc.php');

// Error Output
echo $ipbwi->printSystemMessages();
----------------------------------------

Note here that error messages will display very wrongly as they'll be printed before the <?xml tag.

2) edit /lib/class/CustomAJAXChat.php
----------------------------------------
class CustomAJAXChat extends AJAXChat {

    // Initialize custom request variables:
    function initCustomRequestVars() {
        global $ipbwi;

        // Auto-login IPB users:
        if(!$this->getRequestVar('logout') && $ipbwi->member->isLoggedIn()) {
            $this->setRequestVar('login', true);
        }
    }

    // Returns true if the userID of the logged in user is identical to the userID of the authentication system
    // or the user is authenticated as guest in the chat and the authentication system
    /*function revalidateUserID() {
        global $ipbwi;
       
        $m_info = $ipbwi->member->info();
        if($this->getUserRole() === AJAX_CHAT_GUEST && !$ipbwi->member->isLoggedIn() || ($this->getUserID() === $m_info["id"])) {
            return true;
        }
        return false;
    }*/

    // Returns an associative array containing userName, userID and userRole
    // Returns null if login is invalid
    function getValidLoginUserData() {
        global $ipbwi;

        if ($ipbwi->member->isLoggedIn()) {
            $m_info = $ipbwi->member->info();
            $userData = array();
            $userData["userID"] = $m_info["id"];
            $userData["userName"] = $this->trimUserName($m_info["members_display_name"]);
            if ($ipbwi->member->isAdmin()) {
                $userData["userRole"] = AJAX_CHAT_ADMIN;
            } elseif ($ipbwi->member->isSuperMod()) {
                $userData["userRole"] = AJAX_CHAT_USER;
            } else {
                $userData["userRole"] = AJAX_CHAT_USER;
            }
            return $userData;
        } else {
            // Guest users
            return $this->getGuestUser();
        }
    }
}

    // Store the channels the current user has access to
    // Make sure channel names don't contain any whitespace
    function &getChannels() {
        if($this->_channels === null) {
            $this->_channels = array();
           
            $allChannels = $this->getAllChannels();
           
            // Get the channels, the user has access to:
            if($this->getUserRole() != AJAX_CHAT_GUEST) {
                $validChannels = $allChannels;
            }
           
            // Add the valid channels to the channel list (the defaultChannelID is always valid):
            foreach($this->getAllChannels() as $key=>$value) {
                // Check if we have to limit the available channels:
                if($this->getConfig('limitChannelList') && !in_array($value, $this->getConfig('limitChannelList'))) {
                    continue;
                }
               
                if(in_array($value, $validChannels) || $value == $this->getConfig('defaultChannelID')) {
                    $this->_channels[$key] = $value;
                }
            }
        }
        return $this->_channels;
    }

    // Store all existing channels
    // Make sure channel names don't contain any whitespace
    function &getAllChannels() {
        if($this->_allChannels === null) {
            // Get all existing channels:
            $customChannels = $this->getCustomChannels();
           
            $defaultChannelFound = false;
           
            foreach($customChannels as $key=>$value) {
                $forumName = $this->trimChannelName($value);
               
                $this->_allChannels[$forumName] = $key;
               
                if($key == $this->getConfig('defaultChannelID')) {
                    $defaultChannelFound = true;
                }
            }
           
            if(!$defaultChannelFound) {
                // Add the default channel as first array element to the channel list:
                $this->_allChannels = array_merge(
                    array(
                        $this->trimChannelName($this->getConfig('defaultChannelName'))=>$this->getConfig('defaultChannelID')
                    ),
                    $this->_allChannels
                );
            }
        }
        return $this->_allChannels;
    }
    function &getCustomUsers() {
        // List containing the registered chat users:
        $users = null;
        require(AJAX_CHAT_PATH.'lib/data/users.php');
        return $users;
    }
   
    function &getCustomChannels() {
        // List containing the custom channels:
        $channels = null;
        require(AJAX_CHAT_PATH.'lib/data/channels.php');
        return $channels;
    }
?>
----------------------------------------

The channel list is not working properly and I don't get ay forum list (I still use the custom channel list), but at least, the users don't have to login to AJAX Chat.

Hope it helps

Very usefull. I was able to integrate with IPB 2.3.6.
Thanks!

[Philip Nicolcev]

Oh nice.

You can still manually add channels if you can't get that working automatically. A-la wiki:

http://ajax-chat.wiki.sourceforge.net/Custom+chat+channels

so not a big deal

[Ryan]

Thanks for posting this solution, I somehow missed it months ago!

Unfortunately for me after I followed the instructions, I simply got a bunch of error messages at the top of my chat box and the chat itself didn't work. Most of the errors seem to be variations of

Warning: Cannot modify header information - headers already sent by (output started at /home/admin/public_html/forums/chat/lib/class/CustomAJAXChat.php:132) in /home/admin/public_html/forums/chat/lib/class/AJAXChatHTTPHeader.php on line 45

while the topmost error is

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/admin/public_html/forums/chat/lib/class/CustomAJAXChat.php:132) in /home/admin/public_html/forums/chat/lib/class/AJAXChat.php on line 2471

Any idea what I may be doing wrong?

[Philip Nicolcev]

Yes. Never use notepad or word to edit php files
