Tags : php facebook-login

Facebook login is a popular way for web developer these days to capture user data and at the same time login the user to the protected part of their website. A common question about what happen next after authenticating the user is :

Is there a way to redirect to a URL after the user successfully logs in?

Yes, you can redirect your user to a particular page after authentication by including the redirect_uri parameter.

 $params = array(
 'scope' => 'read_stream, friends_likes',
 'redirect_uri' => 'https://www.myapp.com/post_login_page'
 );

 $loginUrl = $facebook->getLoginUrl($params);

In the event, that you get this error message returned :

 "error": {
 "message": "Error validating verification code.",
 "type": "OAuthException"
 }

Go to https://developers.facebook.com/apps

Make sure that the Canvas URL is set up correctly and the redirect_uri must be one of the URI under the Canvas URL

For example, your canvas URL value is set to http://www.myapps.com , the redirect_uri must be http://www.myapps.com/something or http://www.myapps.com/somecontroller and NOT http://www.someoneelseapps.com/something

Hope this tutorial can be useful.
