Has a User Added My App?
Problem
I need to check whether a user has added my app.
Solution
Use the Users.isAppAdded()
method:
$hasAdded = $facebook->api_client->users_isAppAdded();
Discussion
Users.isAppAdded()
returns a boolean indicating whether the specified user has installed your app. This will check for
the current loggedinuser
by
default, but web-based Facebook apps can also pass in a different
uid
:
$hasAdded = $facebook->api_client->users_isAppAdded('12345');
