In recent times peoples are losing interest to subscribe/ register on sites filling forms! Most people use facebook and there is a easy way to collect their information like email, name, birthday or picture etc.
I wrote a PHP script that can automatically collect user information and save the to MySQL database. It also automatically publish posts to users Wall.

Step 1: You can create MySQL table by following code:

CREATE TABLE `users` (
    `oauth_uid` INT(10) UNSIGNED NOT NULL AUTO_INCREMENT,
    `oauth_provider` VARCHAR(10),
    `username` text,
    `first_name` text,
    `last_name` text,
    `email` text,
    `pic_square` text,
    PRIMARY KEY (`oauth_uid`)
) ENGINE=MyISAM  DEFAULT CHARSET=latin1;

Step 2: Create Facebook session, Database Connect and Authentication

session_start();
 
if (!empty($_SESSION)) {
    header("Location: home.php");
}

mysql_connect('localhost', 'username', 'password');
mysql_select_db('dbname');

Step 3: Add Facebook library and create facebook application object

# require library
require("facebook.php");
 
# Creating the facebook object
$facebook = new Facebook(array(
            'appId' => '164516846996806',
            'secret' => '262fbacd9284301641d572e111113921',
            'cookie' => true
        ));

Step 4: get user id (getUser()) and user info (api->(‘/me’))

    # session active, get user id (getUser()) and user info (api->('/me'))
    try {
        $uid = $facebook->getUser();
        $fb_access_token=$session['access_token'];
        $url = $facebook->getLoginUrl(array(
            'req_perms' => 'email,status_update,publish_stream'
                ));
        $user = $facebook->api('/me');
        $photolink = 'http://graph.facebook.com/'.$user['id'].'/picture?type=square';
        $param = array(
            'method' => 'users.getInfo',
            'uids' => uid,
            'fields' => 'pic_big'
        );
        $users_getinfo = $facebook->api($param);
    } catch (Exception $e) {
 
    }

Step 4: Check if the user is already registered

47
48
49

 
$query = mysql_query("SELECT * FROM users WHERE oauth_provider = 'facebook' AND oauth_uid = " . $user['id']);
        $result = mysql_fetch_array($query);

Step 5: If user has not registered already, add user information to mysql database

53
54
55
56
57
58

 
        if (empty($result)) {
            $query = mysql_query("INSERT INTO users (oauth_provider, oauth_uid, username, first_name, last_name, email, pic_square) VALUES ('facebook', {$user['id']}, '{$user['name']}', '{$user['first_name']}', '{$user['last_name']}','{$user['email']}', '".$photolink."')");
            $query = mysql_query("SELECT * FROM users WHERE id = " . mysql_insert_id());
            $result = mysql_fetch_array($query);
        }

Step 6: Stores Varialbles in the Session

60
61
62
63
64

 
 $_SESSION['id'] = $result['id'];
        $_SESSION['oauth_uid'] = $result['oauth_uid'];
        $_SESSION['oauth_provider'] = $result['oauth_provider'];
        $_SESSION['username'] = $result['username'];

Step 7: Publish to facebook Wall if user permission is accepted

    $api_call = array(
        'method' => 'users.hasAppPermission',
        'uid' => $uid,
        'ext_perm' => 'publish_stream'
    );
    $can_post = $facebook->api($api_call);
    if ($can_post) {
        # post it!
        $facebook->api('/' . $uid . '/feed', 'post', array(
            'message' => 'Participate in Camry Slogan Contest and Win great prizes!',
            'name' => 'Camry Slogan Contest',
            'description' => 'Participate in Camry Slogan Contest and Win iPhone, iPad, Samsung Galaxy, Canono Digital Camera, Sony Play Station, Blackberry Bold and more prizes.',
            'caption' => 'WIN prizes by suggesting us a Slogan for our new Toyota Camry!',
            'picture' => 'http://www.masudonline.net/camry/headar.jpg',
            'link' => 'http://apps.facebook.com/camryslgn/'
        ));
        echo 'Posted!';
    } else {
        die('Permissions required!');
