Facebook Connect button alone can pretty much collect all the information we need from user.  But sometimes we need to collect additional information during the registration, such as favorite Color, number of kittens, movie star name etc. To collect such information, we can use Facebook Registration Plugin. Instead of just showing Facebook Registration plugin, we will use Facebook Login button and call Registration plugin later.  To make it even better I have used colorbox by Jack Moore.

Implementing “Login with Facebook” using just their new PHP SDK is very easy, everything can be accomplished with minimal PHP code, but some of us may want to take it little further to create a nice looking Ajax based login system. Yes, with little bit of Javascript and Facebook PHP SDK, we can create Ajax based Facebook Login system.

With Joomla Facebook Connect 4, Facebook users can quickly register and login on your Joomla websites. This free Joomla extension was re-written from ground up and should work out of the box. Facebook Login module can be configured to show only login button or form.

Posting pictures on Facebook works similar as Posting to Facebook Page Wall, you can post not just photos, but questions, status, notes etc in a similar way. In previous post we have seen how we can post a photo to page wall by specifying its relative path, but in this tutorial we will upload picture and directly post to user profile page using an upload form.
