can't get field permission granted on facebook api 4.0.1

Question

I'm using

        $request = new FacebookRequest($session, 'GET', '/me');
        $response = $request->execute();
        $graphObject = $response->getGraphObject();

to access my profile data on my app (I've accepted the app's specific request for permission to get my primary email address)

I don't get any email field on the response. It works with any test user I create, though. What am I missing?

Even more weird: When I run

    $request = new FacebookRequest($session, 'GET', '/me/permissions');
    $response = $request->execute();
    $graphObject = $response->getGraphObject();
    var_export($graphObject);

I get:

Facebook\GraphObject::__set_state(array(
   'backingData' => 
  array (
    0 => 
    stdClass::__set_state(array(
       'permission' => 'public_profile',
       'status' => 'granted',
    )),
  ),
))

How come the email permission is not even on the list, when I have explicitly added it to "requested permissions" on the app's settings?

Answer 1

I would use the Graph Explorer here to see what you can/should get back: https://developers.facebook.com/tools/explorer/

email is listed under the Extended Permissions tab.

How did you log the user in? You should pass in the scopes including 'email' to the getLoginUrl method.

Answer 2

Solved.

Had to switch

$helper->getLoginUrl();

for

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

('scope' must contain all permissions on a comma separated list)

Answer 3

I did something like this in SDK 4-dev and is working

//permissions request
$request = new \Facebook\FacebookRequest(
    $session,
    'GET',
    '/me/permissions'
);
$response = $request->execute();
$graphObjectPermissions = $response->getGraphObject()->asArray();
//echo '<pre>' . print_r( $graphObjectPermissions,1 ) . '</pre>';

$permissions = [];//create permissions array

foreach ($graphObjectPermissions as $key => $permObject) {
    $permissions[$permObject->permission] = $permObject->status;
}

//check for email permission
if (array_key_exists('email', $permissions ) &&  $permissions['email']=='granted') {
    echo '<pre> email permission granted </pre>';
} else {
    echo '<pre> email Permission denied </pre>';
}

Answer 5

see the 90 line in FacebookRedirectLoginHelper.php ... it looks like

public function getLoginUrl($scope = array(), $version = null)

I change by

public function getLoginUrl($scope = array('email'), $version = null)

and works!!!
