facebook php sdk设置重定向网址

Question

What I do is,

I start by making a call with ajax to the controller/function "users/authenthicate"

This function get's the loginurl from the sdk and returns it to javascript wich does the window.open.href... sofar sogood.. I get directed to the facebook loginpage,

but after a successvol login, it redirects back to the same users/authenticate.

QUESTION: is this the normal behaviour? or can I set the redirecturl..

QUESTION: it returns the url without a slash between the questionmark so the function is never recognized like this "users/authenthicate?bladeblibla".

*I did set some url when I registred the application, but that was a completely different url something like "http://www.domain/users/facebook_login"*

thanks Richard

Answer 1

You can set the redirect URI as follows:

$linkToOauthDialog = $this->facebook->getLoginUrl(

  array(
     'scope'         =>  SCOPE_OF_THE_APP,
     'redirect_uri'  =>  REDIRECT_URI
  )

);

You should also have in mind that Safari doesn't allow setting third party cookies in an iframe, that's why you need to redirect to your own domain first, where you set a cookie and redirect to facebook again. Otherwise you end up in an infinite loop.

I have described this method in more detail here: Safari 3rd party cookie iframe trick no longer working?

Yes, this is the default behaviour of the php sdk. When you call getLoginUrl() and you don't specify the redirect_uri at the param array, it will try to use the current url.

I think what you would want to use is the JS sdk's FB.login() method instead of redirects with window.open (will be opening popups trough but you will get information back in you page's js).
