login with facebook using oauth

facebook, facebook-graph-api, php

Solution

You could use POST request to simulate login. I don't know Facebook's inputs, so you need to look closely into it's HTML, but here is a code for a simple PHP cURL request.

// Get cURL resource
$curl = curl_init();
// Set some options - we are passing in a useragent too here
curl_setopt_array($curl, array(
    CURLOPT_RETURNTRANSFER => 1,
    CURLOPT_URL => 'https://www.facebook.com/login.php',
    CURLOPT_USERAGENT => 'Facebook Login',
    CURLOPT_POST => 1,
    CURLOPT_POSTFIELDS => array(
        'username' => 'username',
        'password' => 'myfbpass'
    )
));
// Send the request & save response to $resp
$resp = curl_exec($curl);
// Close request to clear up some resources
curl_close($curl);

Of course, Facebook has automatic login detection by using those hidden fields for getting the sessions, but using DOM Document, you can easily get those values and emulate it, at least thats how I was able to simulate login for http://z8games.com/

Good luck
