I currently have a Joomla 1.5 installation, as well as another website. They both reside on the same web server. They are in different folders within the wwwroot directory, however. I would like to place a login form within the non-joomla website, which will log the user in to Joomla. I have already tried copying and pasting the Joomla login form code into a page on the non-joomla site, and everything works fine up until the secret form value is not correct. Any help is greatly appreciated.

EDIT:
Here is the code-

Login Script:

$upswd = $_POST['password'];
$url = "http://www.mywebsite.com/joomla_site/index.php";

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url );
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE );
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE );
curl_setopt($ch, CURLOPT_COOKIEJAR, './cookie.txt');
curl_setopt($ch, CURLOPT_COOKIEFILE, './cookie.txt');
curl_setopt($ch, CURLOPT_HEADER, FALSE );
$ret = curl_exec($ch);
if (!preg_match('/name="([a-zA-z0-9]{32})"/', $ret, $spoof)) {
    preg_match("/name='([a-zA-z0-9]{32})'/", $ret, $spoof);
}

// POST fields
$postfields = array();
$postfields['username'] = urlencode($uname);
$postfields['passwd'] = urlencode($upswd);
$postfields['lang'] = '';
$postfields['option'] = 'com_login';
$postfields['task'] = 'login';
$postfields[$spoof[1]] = '1';
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postfields);
$ret = curl_exec($ch);
?>

    Ok, in order for this to work here is what needs to be done –

    1. Create a new session and get the associated token
    2. Pass the username, password, and token to create a logged in session
    3. Get the new cookie values for logged in session
    4. Transfer cookie to the browser

    Here is the code needed to accomplish all of this:

    <?php
$uname = $_POST['username'];
$upswd = $_POST['password'];
$url = "http://joomla website.com";

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url );
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE );
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE );
curl_setopt($ch, CURLOPT_COOKIESESSION, TRUE );
curl_setopt($ch, CURLOPT_COOKIEJAR, realpath('./cookie.txt'));
curl_setopt($ch, CURLOPT_COOKIEFILE, realpath('./cookie.txt'));
curl_setopt($ch, CURLOPT_HEADER, TRUE );
$ret = curl_exec($ch);
if (!preg_match('/name="([a-zA-z0-9]{32})"/', $ret, $spoof)) {
    preg_match("/name='([a-zA-z0-9]{32})'/", $ret, $spoof);
}

// POST fields
$postfields = array();
$postfields['username'] = urlencode($uname);
$postfields['passwd'] = urlencode($upswd);
$postfields['option'] = 'com_user';
$postfields['task'] = 'login';
$postfields[$spoof[1]] = '1';
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postfields);
$ret = curl_exec($ch);

// Get logged in cookie and pass it to the browser
preg_match('/^Set-Cookie: (.*?);/m', $ret, $m);
$cookie=explode('=',$m[1]);
setcookie($cookie[0], $cookie[1]);
?>

    This should work on any Joomla website as long as the URL used in the script has a login form on the page. Once you run this script you should then be able to access the website and be logged in.
