Facebook appp only I get my email when login in the app

Question

I'm developing a Facebook app with facebook/php-sdk-v4, the scope is:

$permissions = ['email', 'public_profile'];

When I test the app all is ok, I can get my email, but whet other users login with their Facebook account I can't get their email address.

How I can get all emails of users that login in my app?

Answer 1

When you use the php sdk you need to specify the fields you want using the field parameter in the request URL :

me?field=email

You also can use the Graph API Explorer to try your Graph request :
