Getting Started

So, let’s get started with your first Facebook application written with CodeIgniter. By the end of it, you’ll have everything you need to create a Facebook application.

1. Download CodeIgnier Framework and Install it. if you install currently , You should see the generic message, “Welcome to CodeIgniter!” If you don’t, you’ve missed something along the way. Reinstall CodeIgniter and start over.

2. Go to Facebook.com/developers and set up a new application.

3. now download Codeigniter Facebook SDK library, to download click here

4.copy and place config and library directory in your ci app.

How do I use it?

You can load the facebook sdk like other libraries in Codeigniter , but you need to set config values in config/facebook.php , Enter your app ID and secret code there.

That’s it your done!.

    But how to get email and other information

    Please reply me

    • To fetch email address you must have the permission to access it. To request permissions, add email to the scope as shown below –

      $facebook->getLoginUrl(array(‘scope’ => ’email,read_stream’));

      • Payer Centavos

        Hi I’ve tried that but it comes with an FB error:
        Invalid Scopes: read_stream. This message is only shown to developers. Users of your app will ignore these permissions if present.
