facebook incorrect ids being compared

I am having difficulty with facebook user ids in our system. After retrieving the information via the facebook api, i store the information in the database and then use the $facebook->getUser() method on the page load to log the user in.

Here is the insert code I am using:

           $user = $facebook->getUser();
           //insert sql statement using $user as `fuid`

My problem is that it keeps asking for the same incorrect facebook id no matter how many times I do the following:

  • clean out cookies and history
  • use the $facebook->destroySession() method

It looks like it's the id from my initial usage of the api.

Any ideas what I should be doing?

Solution

  • Probably you're having the "old" global ids in you database, and you app now returns app-scoped user ids.
