How to&Answers:

I suggest you start learning how Facebook Graph API works first.

  1. Facebook will NEVER share the user password with you!
  2. If you just need to give the user the possibility to share link, then just use the like plugin. You may also find more interesting social plugins to use in your website.
  3. If you use the like plugin, it won’t open any popups and it would post the link directly to the user’s wall.
  4. You could always use the Feed Dialog
  5. Start reading the Facebook Documentation

Now to post on the user’s wall (on his behalf) without him being logged-in, you need the following:

  1. app access_token
  2. publish_stream permission, NO NEED for the long-lived access token:

Enables your app to post content, comments, and likes to a user’s
stream and to the streams of the user’s friends. This is a superset
publishing permission which also includes publish_actions. However,
please note that Facebook recommends a user-initiated sharing model.
Please read the Platform Policies to ensure you understand how to
properly use this permission. Note, you do not need to request the
publish_stream permission in order to use the Feed Dialog, the
Requests Dialog or the Send Dialog.

Require the permission:
This can be done in multiple of ways:
Using the Login Plugin:

<div class="fb-login-button" data-show-faces="true" data-width="200" data-scope="publish_stream" data-max-rows="1"></div>

Server-side login (Redirect to the OAuth Dialog):



$loginUrl = $facebook->getLoginUrl(array("scope"=>"publish_stream"));

JS-SDK through the FB.login method:

 FB.login(function(response) {
   if (response.authResponse) {
     console.log('Welcome!  Fetching your information.... ');
     FB.api('/me', function(response) {
       console.log('Good to see you, ' + response.name + '.');
       FB.logout(function(response) {
         console.log('Logged out.');
   } else {
     console.log('User cancelled login or did not fully authorize.');
 }, {scope: 'publish_stream'});


$USER_ID = "XXXXXXXX"; // Connected once to your APP and not necessary logged-in at the moment
$args = array(
    'message'   => 'Hello from app',
    'link'      => 'http://www.masteringapi.com/',
    'caption'   => 'Visit MasteringAPI.com For Facebook API Tutorials!'
$post_id = $facebook->api("/$USER_ID/feed", "post", $args);

While it’s possible to post without the user’s presence always remember Facebook recommends a user-initiated sharing model
