Hosting CometChat on a separate server/sub-domain
CometChat has full cross-domain support. You can run CometChat on a separate server, domain/sub-domain. Note, some plugins like page translation may not work when used in cross-domain environment.
An ideal use of this feature is when you want to load CometChat on a separate server e.g. chat.yoursite.com and want to use CometChat on www.yoursite.com.
Perform the following steps:
Modify your getUserID() function so that it is similar to below. The “basedata” value will be sent when the user logs into to your main domain.
function getUserID() {
$userid = 0;
if (!empty($_SESSION['basedata']) && $_SESSION['basedata'] != 'null') {
$_REQUEST['basedata'] = $_SESSION['basedata'];
}
if (!empty($_REQUEST['basedata'])) {
$userid = $_REQUEST['basedata'];
}
return $userid;
}
- Edit cometchat/config.php and set BASE_URL to the full path e.g. http://chat.yoursite.com/cometchat/
- Then set CROSS_DOMAIN to 1
- Add the following code to the site template (remember to include the full URL path).
Add the code immediately after <head> tag:
<script>
var userid = 'USERID'; // Must be populated programmatically
document.cookie = "cc_data="+userid;
</script>
<link type="text/css" rel="stylesheet" media="all" href="http://chat.yoursite.com/cometchat/cometchatcss.php" />
<script type="text/javascript" src="http://chat.yoursite.com/cometchat/cometchatjs.php" charset="utf-8"></script>
Use of CometService or alternatives is strongly recommended when using CometChat in cross-domain environment. This guide will work for custom coded sites only.
