Error when including redirect_uri with getLoginUrl (Facebook PHP SDK)

问题

I want the user to be redirected to a particular webpage after logging in using Facebook. I created a LoginUrl using Facebook PHP SDK and the user clicks on this link to log in. I followed http://developers.facebook.com/docs/reference/php/facebook-getLoginUrl/ when using the $facebook->getLoginUrl()

Problem: If I were to include the redirect_uri parameter, Facebook gives me an error An error occurred. Please try again later. The login url works fine without including the redirect_uri.

Anyone knows how to fix this? Thanks!

Non-working PHP Code

$loginUrl = $facebook->getLoginUrl(array(
        "scope" => "email,user_education_history,user_work_history",
        "redirect_uri" => "http://mydomain.com/login/facebook"
    ));

Working PHP Code

$loginUrl = $facebook->getLoginUrl(array(
        "scope" => "email,user_education_history,user_work_history",
    ));

I had this same exact problem. FB changed the parameter from redirect_url to next from v2 to v3, and is poooooorly documented. Try next, should work for you.

It's pretty old topic, but here is the solution I've found working, if someone reads it later... First thing is that you have missed the comma after "redirect_uri" in your "Non-working PHP Code". And if you have "App on Facebook" selected in your application settings (app in Canvas) then your redirect_uri must be the same as the url you have set for Canvas App. If you are using just Page Tab, the redirect_uri can be anything.

$loginUrl = $facebook->getLoginUrl(array(
    "scope" => "email,user_education_history,user_work_history",
    "redirect_uri" => "http://mydomain.com/login/facebook",
));
