Problem with ajax im

[ryan2345]

Hi,
Ive downloaded ajax im messenger. I want to integrate it with my project.
Project is in PHP and MySql.
I already have a login page in my project. I wanted that it should work with the same login page.
I didnt wanted to use the ajaxim login page.
Is it possible to do it. How can it be done.
I tried learning the code but couldnt make the changes i needed.
Can you plz guide me with this

The Ajax login might be setting some cookies or session. Do the same with your PHP code.
Or in the Ajax IM page, if its validating some cookies, change the name of cookie to the one you are creating in your login page.

It is seting session and i hve also used sessioms in my login page. But still couldnt get it. I ve pasted part of the file i think that needs to be changed.

function sanitize_alphan um($string, $min='', $max='')
{
$string = preg_replace('/[^a-zA-Z0-9\s]/', '', $string);
$len = strlen($string) ;
if((($min != '') && ($len < $min)) || (($max != '') && ($len > $max)))
return FALSE;
return $string;
}

// connect to database //
$link = mysql_connect($ sql_host, $sql_user, $sql_pass);
mysql_select_db ($sql_db);
mysql_query('SE T NAMES \'utf8\'');

session_start() ;

class Ajax_IM {
function Ajax_IM($call) {
$this->json = new JSON_obj();

$this->username = $_SESSION['username'];
$this->password = $_SESSION['password'];

// run the garbage collector (chance run)
$this->gc();

// figure out which action we need to execute,
// then execute it and print the output
switch($call) {

The login page for ajax im is index.html
I tried editing it. I removed the new user register and forgot password part from it.
Now i want that when a user is logged in my sitr then just by clicking on the im option he should be able to chat without logging in again.
The code of index.html is here:
Plz help me out.
