In order to use CometChat mobile app with your website, you need to make sure that you are using CometChat version 5.0.0+
Also, refer to the following steps for troubleshooting any login issues:
1. If you have white labelled CometChat on your web site, then please use http://<your site URL>/<white labelled name for cometchat>/ as URL.
for example: http://www.mysite.com/
mywhitelabelledcometchat/
2. If you are getting an error message “Username and password do not match” then please make sure you have configured chatLogin function correctly.
This function takes username/email and password as input and returns encrypted userID (primary key of your site’s users table) after authenticating user based on your authentication mechanism.
For example:
function chatLogin($userName, $userPass) {
$userid = 0;
if (filter_var($userName, FILTER_VALIDATE_EMAIL)) {
$sql = ("SELECT * FROM `".TABLE_PREFIX.DB_USERTABLE.
"` WHERE email ='".$userName.
"'");
} else {
$sql = ("SELECT * FROM `".TABLE_PREFIX.DB_USERTABLE.
"` WHERE username ='".$userName.
"'");
}
$result = mysqli_query($GLOBALS['dbh'], $sql);
$row = mysqli_fetch_assoc($result);
$salted_password = md5($row1['value'].$userPass.$row['salt']);
if ($row['password'] == $salted_password) {
$userid = $row['user_id'];
if (isset($_REQUEST['callbackfn']) && $_REQUEST['callbackfn'] == 'mobileapp') {
$sql = ("insert into cometchat_status (userid,isdevice) values ('".mysqli_real_escape_string($GLOBALS['dbh'], $userid).
"','1') on duplicate key update isdevice = '1'");
mysqli_query($GLOBALS['dbh'], $sql);
}
}
if ($userid && function_exists('mcrypt_encrypt') && defined('ENCRYPT_USERID') && ENCRYPT_USERID == '1') {
$key = "";
if (defined('KEY_A') && defined('KEY_B') && defined('KEY_C')) {
$key = KEY_A.KEY_B.KEY_C;
}
$userid = rawurlencode(base64_encode(mcrypt_encrypt(MCRYPT_RIJNDAEL_256, md5($key), $userid, MCRYPT_MODE_CBC, md5(md5($key)))));
}
return $userid;
}
3. Please make sure you have added the following code in getUserID function after $userid=0; like:
function getUserID() {
$userid = 0;
if (!empty($_SESSION['basedata']) && $_SESSION['basedata'] != 'null') {
$_REQUEST['basedata'] = $_SESSION['basedata'];
}
if (!empty($_REQUEST['basedata'])) {
if (function_exists('mcrypt_encrypt') && defined('ENCRYPT_USERID') && ENCRYPT_USERID == '1') {
$key = "";
if (defined('KEY_A') && defined('KEY_B') && defined('KEY_C')) {
$key = KEY_A.KEY_B.KEY_C;
}
$uid = rtrim(mcrypt_decrypt(MCRYPT_RIJNDAEL_256, md5($key), base64_decode(rawurldecode($_REQUEST['basedata'])), MCRYPT_MODE_CBC, md5(md5($key))), "");
if (intval($uid) > 0) {
$userid = $uid;
}
} else {
$userid = $_REQUEST['basedata'];
}
}
if (!empty($_SESSION['userid'])) {
$userid = $_SESSION['userid'];
}
$userid = intval($userid);
return $userid;
}
