Basic integration

Hi. I've been trying to integrate gallery 2 with Torrent Trader (http://www.torrenttrader.org) to no avail. I've followed the documentation here and also tried to apply what's been done here.

I've created a file called gallery.php (a.k.a. embed.php) which looks like this:

#!/usr/bin/php4-cgi
<?php
require_once(dirname(__FILE__) . '/gallery/embed.php');
$userid = $_COOKIE["uid"];
$ret = GalleryEmbed::init(array( 'embedUri' => '/home/paddypunk/paddypunk/gallery2.php', 'g2Uri' =>
'/home/paddypunk/paddypunk/gallery', 'loginRedirect' => '/home/paddypunk/paddypunk/account-login.php',
'activeUserId' => $userid));
if ($ret) {
  // $ret->getAsHtml() has error details..
  exit;
}
$g2data = GalleryEmbed::handleRequest();
if ($g2data['isDone']) {
  exit; // Gallery 2 has already sent output (redirect or binary data)
}
// Use $g2data['headHtml'] and $g2data['bodyHtml']
// to display Gallery 2 content inside embedding application
// if you don't want to use $g2data['headHtml'] directly, you can get the css,
// javascript and page title separately by calling...
if (isset($g2moddata['headHtml'])) {
  list($title, $css, $javascript) = GalleryEmbed::parseHead($g2moddata['headHtml']);
}



?>

I'm also dealing with two other files, account-login.php and account-logout.php:

account-login.php:

#!/usr/bin/php4-cgi
<?
//
// CSS and Language updated 30.11.05
//
ob_start();
require_once('gallery/embed.php');
require_once("backend/functions.php");
dbconn();

unset($returnto);
if (!empty($_GET["returnto"])) {
        $returnto = $_GET["returnto"];
        if (!$_GET["nowarn"]) {
                $message = "" . SORRY_MEMBERS_ONLY . "";
        }
}

if (mkglobal("username:password")) {
        $password = md5($password);

        $res = mysql_query("SELECT id, password, secret, enabled FROM users WHERE username = " . sqlesc($username) . " AND status = 'confirm$
        $row = mysql_fetch_array($res);

        if (!$row)
                $message = "" . USERNAME_WRONG . "";
        elseif ($row["password"] != $password)
                $message = "" . PASSWORD_WRONG . "";
        elseif ($row["enabled"] == "no")
                $message = "" . ACCOUNT_DISABLED . "";
        else {
                logincookie($row["id"], $row["password"], hash_pad($row["secret"], 20));
                if (!empty($_POST["returnto"])) {
                        header("Refresh: 0; url=" . $_POST["returnto"]);
                        die();
                }
                else {
                        header("Refresh: 0; url=index.php");
                        die();
                }
        }
}

logoutcookie();

stdhead("Login");

begin_frame("" . LOGIN . "");

if ($message != "")
        bark2("Access Denied", $message);
?>

<form method="post" action="account-login.php">
        <div align="center">
        <table border="0" cellpadding=5>
                <tr><td><B><?echo "" . USERNAME . "";?>:</B></td><td align=left><input type="text" size=40 name="username" /></td></tr>
                <tr><td><B><?echo "" . PASSWORD . "";?>:</B></td><td align=left><input type="password" size=40 name="password" /></td></tr>
                <tr><td colspan="2" align="center"><input type="submit" value="<?echo "" . LOGIN . "";?>" class=btn><BR><BR><i><?echo "" . C$
        </table>
        </div>
<?

if (isset($returnto))
        print("<input type=\"hidden\" name=\"returnto\" value=\"" . htmlspecialchars($returnto) . "\" />\n");

?>

</form>
<p align="center"><a href="account-signup.php"><?echo "" . REGISTERNEW . "";?></a> | <a href="account-recover.php"><?echo "" . RECOVER_ACCOU$

<?
end_frame();
stdfoot();
?>

account-logout.php

#!/usr/bin/php4-cgi
<?
// Logout of site, clear cookie and return to index
require_once("backend/functions.php");
//require_once('/home/paddypunk/paddypunk/gallery/embed.php');
dbconn();
logoutcookie();
Header("Location: $SITEURL/index.php");

?>

As you can see account-logout.php doesn't contain any gallery 2 related code yet.
I'm really lost as to how I'm supposed to be using the code in the documentation and any helpful info would be much appreciated.

Thanks in advance,
Bernard
