Scope parameter is ignored by facebook login

Question

I am trying to use Facebooks PHP SDK to login to my page. However, Facebook ignores the permissions given as an array in getLoginUrl()

$loginUrl = $helper->getLoginUrl(
    ['publish_actions']
);

The login url looks like:

https://www.facebook.com/v2.3/dialog/oauth?client_id=206265226055767&redirect_uri=http://host.tld/remote/gateway.php&state=67096befe627aa603cb086da681626c1&sdk=php-sdk-4.0.23&scope=publish_actions

However, Facebook still ask for my public_profile and my email

• I have administrator privileges
• The app is still in development mode

My Question is why Facebook ignores the scope parameter on the oauth login dialog.

Answer 1

Try with this code:

$params = array(
  'scope' => 'publish_actions',
  'redirect_uri' => 'https://www.myapp.com/post_login_page'
);

$loginUrl = $facebook->getLoginUrl($params);

Not sure if it works the same way with the PHP SDK 4.x though, but you can try this:

$scope = array('publish_actions');
$loginUrl = $helper->getLoginUrl($scope);

...from the well upvoted answer in this thread: Specify app scopes in php facebook sdk 4.0.0 or greater

Of course you can also write it like this:

$loginUrl = $helper->getLoginUrl(array('publish_actions'));

Not sure if it helps in your case, the literal array definition should definitely work in PHP...but you never know ;)
