Getting Dropbox - 403 error when logging on using dropboxuploader.php - dropbox

Question

Hey I'm using dropboxuploader.php to login into dropbox. All was working fine, but when i came into work yesterday i could no longer connect. This is what dropbox is returning to me.
HTTP/1.1 100 Continue
HTTP/1.1 403 Forbidden
Server: nginx/1.2.3
Date: Thu, 04 Oct 2012 08:44:36 GMT

It seems you tried to do something we can't verify. Did you log into a different Dropbox account in a different window? Try clicking here to go back to the page you came from, or just go home.

Answer 1

Replace the login function with below code and it should work:
protected function login() {
$data = $this->request('https://www.dropbox.com/login');
$str = '<input type="hidden" name="t" value="';
$start = strpos($data,$str);
$val = "";
if($start !== false)
{
$val = substr($data,$start+strlen($str),24);
}
$data = $this->request('https://www.dropbox.com/login', true, array('login_email'=>$this->email, 'login_password'=>$this->password, 't'=>$val));
if (stripos($data, 'location: /home') === false)
throw new Exception('Login unsuccessful.');
$this->loggedIn = true;
}

Just update your dropbox uploader file instead doing your fixes.
