Hi E's, I am a beginner in Facebook Developers using Javascript or other language:
I have this code, that I copy from the examples of FB developers site:
<html>
<head></head>
<body>
<div id="fb-root"></div>
<script>
  window.fbAsyncInit = function() {
  FB.init({
    appId      : '463164587035065', // App ID
    channelUrl : 'www.wwdablio.org', // Channel File
    status     : true, // check login status
    cookie     : true, // enable cookies to allow the server to access the session
    xfbml      : true  // parse XFBML
  });
  
  FB.Event.subscribe('auth.authResponseChange', function(response) { 
    if (response.status === 'connected') {
      testAPI();
    } else if (response.status === 'not_authorized') {
      FB.login();
    } else {
      FB.login();
    }
  });
  };

  // Load the SDK asynchronously
  (function(d){
   var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0];
   if (d.getElementById(id)) {return;}
   js = d.createElement('script'); js.id = id; js.async = true;
   js.src = "//connect.facebook.net/en_US/all.js";
   ref.parentNode.insertBefore(js, ref);
  }(document));

  function testAPI() {      
    console.log('Welcome!  Fetching your information.... ');
    FB.api('/me', function(response) {
      console.log('Good to see you, ' + response.name + '.');
    });
  }
  
</script>
<fb:login-button show-faces="true" width="200" max-rows="1"></fb:login-button>
</body>
</html>

Open in new window

What the above code do, is verify if the user is login in FB, if not, the user have the opportunity to make login.
The problem is by default the API just give the basic permission, and I want try more kind of permissions, like "user_birthday" and "user_location".
I just need to know, and using the code above, where I can request the permissions "user_birthday" and "user_location", and how?

The best regards, JC

Go here : https://developers.facebook.com/docs/reference/plugins/login/
Attributes section :
scope - a comma separated list of extended permissions. By default the Login button prompts users for their public information. If your application needs to access other parts of the user's profile that may be private, your application can request extended permissions. A complete list of extended permissions can be found here.

Permissions : https://developers.facebook.com/docs/reference/login/#permissions

Extended Profile Properties
- user_birthday
- user_location

<fb:login-button show-faces="true" width="200" max-rows="1" scope="user_birthday,user_location"></fb:login-button>
