使用oauth登录facebook

Question

<?php
require "facebook.php";

$facebook = new Facebook(array(
    'appId'  => '3288@@@@@@@@@@',
    'secret' => 'ca2@@@@@@@@@@@@@@@@@@',
));

$user = $facebook->getUser();

I have made the app in the graph api and I have very little knowledge of graph api . I want to make a facebook login page in which user clicked on it and my app will generate the oauth for the user . after that i need the USERNAME, EMAIL,BIRTHDAY,NAME in the fre filled forms

I'm searching for this code from 3 night, but i didn't find the solution! If you have a suggestion, please write to me it! Please, anyway thanks and good day :)

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

Temboo makes it simple to implement Facebook OAuth by breaking the process down into two steps:

• ÌnitializeOAuth returns the Facebook authorization URL that you need to show your users so that they can grant your app access to their Facebook accounts.
• FinalizeOAuth returns the access token you need to programmatically read/write a user's Facebook data.

What's more, you can test these calls from your browser and generate the source code you need in the language of your choice.

Here's a short video that shows you how to do this with Temboo, and you can check out an example and source code here .
