Question

Is there a way to use the facebook connect api in a static way?

When we use the facebook php sdk the link or button to login to facebook is something like https://www.facebook.com/dialog/oauth………………

what I want is to eliminate the include of the php sdk on every page, because it will cause some extra processing and server load in peak times.

I want to make a session check to know if the user is logged in, by checking for exemple if his facebook user id and name are stored in the session, then if not, display a static login button. then after login with facebook he gets to facebook-login.php which will include the facebook php sdk and process his data and store them in the session, so that he remains logged without including the php sdk in each page.

the url structure that I get with $facebook->getLoginUrl() is:

https://www.facebook.com/dialog/oauth?client_id={MY_APP_KEY}&scope={PERMISSIONS}&redirect_uri={MY_SITE/facebook-login.php}&state={A_32_CHAR_CODE_LIKE_MD5_MAYBE}

The final question is: WHAT WOULD BE THE URL IN THE LOGIN BUTTON?

Answer 1

just load the sdk and do something like:

echo '<a href="' . $facebook->getLoginUrl( array('next'=>'http://mysite.com', 'req_perms' => 'email,read_stream,publish_stream')) . '">Connect to Facebook</a>';

that url will always be valid for a logged out user
