In my application, I have a "user" table that has the following structure.
CREATE TABLE IF NOT EXISTS `users` (
`userId` int(10) unsigned NOT NULL auto_increment,
`username` varchar(128) NOT NULL default '',
`password` varchar(32) NOT NULL default '',
`email` text NOT NULL,
`newsletter` tinyint(1) NOT NULL default '0',
`banned` enum('yes','no') NOT NULL default 'no',
`admin` enum('yes','no') NOT NULL default 'no',
`signup_ip` varchar(20) NOT NULL default '',
`activation_key` varchar(60) NOT NULL default '',
`resetpassword_key` varchar(60) NOT NULL default '',
`createdon` datetime NOT NULL default '0000-00-00 00:00:00',
PRIMARY KEY (`userId`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=27 ;
I want to implement social login via Facebook, Twitter, and OpenID in my application, just like StackOverflow did. Please suggest to me what all changes I will require in my DB and how the logic will be implemented in PHP, alongside with existing login facility.
Thanks!
