Retrieve user email via php facebook sdk API

Question

I followed the example (example.php) of this project: https://github.com/facebook/facebook-php-sdk

It runs very well and I can retrieve a lot of informations from a facebook account (name, id, first name, last name, city...) but I cannot see the user email, that is the only thing I need...

How can I modify that page to retrieve ONLY the user email?

Thanks!

Answer 1

You have to ask for the email permission first, when the user logs in to your app – see https://developers.facebook.com/docs/authentication/permissions/

How can I modify that page to retrieve ONLY the user email?

After getting the permission, if you don't want all the additional fields, use the fields parameter in your Graph API call, as in /me?fields=email (it'll still give you the user id as well, but not any other info you might not need).

Answer 2

You can get email by using this code

function fqlQuerynew() {
           FB.api('/me', function (response) {
                var query = FB.Data.query('select name,email,hometown_location, sex, pic_square from user where uid={0}', response.id);
                query.wait(function (rows) {
                    alert(rows[0].name);
                     alert(rows[0].email);
                     alert(rows[0].sex);
                     alert(rows[0].pic_square);
                });
            });
        }
