Facebook and Twitter have become large in the social network world and both networks offering oAuth support. We developed a system to login with Twitter and Facebook. Nowadays web users not interested to filling the big registration forms. This script helps you to avoid registration forms, It’s is very useful and simple to integrate.



Database

Sample database users table columns id, email, oauth_uid, oauth_provider and username.

CREATE TABLE users
(
id INT PRIMARY KEY AUTO_INCREMENT,
email VARCHAR(70), 
oauth_uid int(11),
oauth_provider VARCHAR(100),
username VARCHAR(100), 
twitter_oauth_token VARCHAR(200), 
twitter_oauth_token_secret VARCHAR(200) 
);

The tutorial contains three folders called facebook,twitter and config with PHP files.

facebook //Facebook OAUTH library 
twitter //Twitter OAUTH library 
config
-- functions.php 
-- dbconfig.php //Database connection 
-- fbconfig.php //Facebook API connection
-- twconfig.php //Twitter API connection
index.php
