Use something else instead.</h2> <hr> <p>If you want to use the access token of the user even after he has logged out of your app, you have to ask for the <code>offline_access</code> permission.</p> <p>With the Facebook PHP SDK v3 (<a href="https://github.com/facebook/php-sdk" rel="nofollow">see on github</a>), it is pretty simple. To log someone with the <code>offline_access</code> permission, you ask it when your generate the login URL. Here is how you do that.</p> <h1>Get the offline access token</h1> <p>First you check if the user is logged in or not :</p> <pre><code>require "facebook.php"; $facebook = new Facebook(array( 'appId' => YOUR_APP_ID, 'secret' => YOUR_APP_SECRET, )); $user = $facebook->getUser(); if ($user) { try { $user_profile = $facebook->api('/me'); } catch (FacebookApiException $e) { $user = null; } } </code></pre> <p>If he is not, you generate the "Login with Facebook" URL asking for the <code>offline_access</code> permission :</p> <pre><code>if (!$user) { $args['scope'] = 'offline_access'; $loginUrl = $facebook->getLoginUrl($args); } </code></pre> <p>And then display the link in your template :</p> <pre><code><?php if (!$user): ?> <a href="<?php echo $loginUrl ?>">Login with Facebook</a> <?php endif ?> </code></pre> <p>Then you can retrieve the offline access token and store it. To get it, call :</p> <pre><code>if ($user) { $token = $facebook->getAccessToken(); // store token } </code></pre> <h1>Use the offline access token</h1> <p>To use the offline access token when the user is not logged in :</p> <pre><code>require "facebook.php"; $facebook = new Facebook(array( 'appId' => YOUR_APP_ID, 'secret' => YOUR_APP_SECRET, )); $facebook->setAccessToken("..."); </code></pre> <p>And now you can make API calls for this user :</p> <pre><code>$user_profile = $facebook->api('/me'); </code></pre> <p>Hope that helps !</p>
