    <p>I try to get 60 days facebook access token from server side request. After user is loged in I check access token through getAccessToken() function from Facebook SDK and after that I use getExtendedAccessToken() which I found somewhere here: <a href="https://stackoverflow.com/questions/8982025/how-to-extend-access-token-validity-since-offline-access-deprecation">How to extend access token validity since offline_access deprecation</a> to ask for 60 days access token:</p> <pre><code> public function getExtendedAccessToken() { try { // need to circumvent json_decode by calling _oauthRequest // directly, since response isn't JSON format. $access_token_response = $this-&gt;_oauthRequest( $this-&gt;getUrl('graph', '/oauth/access_token'), $params = array( 'client_id' =&gt; $this-&gt;getAppId(), 'client_secret' =&gt; $this-&gt;getApiSecret(), 'grant_type'=&gt;'fb_exchange_token', 'fb_exchange_token'=&gt;$this-&gt;getAccessToken(), )); } catch (FacebookApiException $e) { // most likely that user very recently revoked authorization. // In any event, we don't have an access token, so say so. return false; } if (empty($access_token_response)) { return false; } $response_params = array(); parse_str($access_token_response, $response_params); if (!isset($response_params['access_token'])) { return false; } return $response_params['access_token']; } </code></pre> <p>Unfortunanely it still won't work my access token expired after 2 hours so I tried also this:</p> <pre><code> public function getSimpleExtendedAccessToken(){ $request = 'https://graph.facebook.com/oauth/access_token? client_id='. $this-&gt;getAppId(). '&amp;client_secret=' .$this-&gt;getApiSecret(). '&amp;grant_type=fb_exchange_token &amp;fb_exchange_token=' .$this-&gt;getAccessToken(); $response = file_get_contents($request); $params = null; parse_str($response, $params); return $params['access_token']; } </code></pre> <p>and this one also expired after 2 hours. But when I checked what was inside the array <code>$params</code> in the second function there was written:</p> <blockquote> <p>Array ( [access_token] => AAAFM5sO7[...] [expires] => 4897 )</p> </blockquote> <p>(That part: "<code>AAAFM5sO7[...]</code>" is of course my access token number)</p> <p>All access tokens which I received are the same: first one from <code>getAccessToken()</code>, second one from <code>getExtendedAccessToken()</code> and third one from <code>getSimpleExtendedAccessToken()</code>. </p> <p>Of course when I ask addtionaly more and more for extended access token the expiration number doesn't renew but it's counting down, and that is correct from the point of view of the Facebook documentation, because you can't ask for new access token each minute, but why I can't get 60 days access token?</p> <p>Can anyone help me because I'm a bit cofused?</p>

    1. COIt might worth actually catching the error in your `try`/`catch` block, as that may hold the key. Save it to a text file; I believe the Facebook samples have you just simply do `error_log($e)`.

    2. COI don't think so, because I received an access token from the first function `getExtendedAccessToken()`, not false as it is indicated in the error section of `try/cach`. Also second function `getSimplyExtendedAccessToken()` gives me valid access token - and this second function doesn't have `try/cach` section.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
