    <p><em>There is data called 'session' in the URL. Does this need to be stored in order to continually get the user ID?</em></p> <p>Yes, it needs to be stored, but the Facebook class parses it and stores it in a cookie for you.</p> <hr> <p><em>Also, would it be easier to just cut out the PHP library altogether and just handle the reponse myself, storing it in a session variable.</em></p> <p>The <code>Facebook</code> class provided in <strong>facebook.php</strong> is not necessary to use the API but provides a few conveniences for you, such as putting together common URLs, parsing session data (which is sent to the URL and then stored in a cookie), turning error messages (a JSON object with an "error" key) into a PHP Exception, etc.</p> <p>So, in short, no, it wouldn't be easier to cut out the PHP library because you'd end up writing basically the same stuff.</p> <p>As you can see from the example, they are getting the User ID (<code>$uid</code>) by calling <code>getUser</code>:</p> <pre><code>if ($session) { try { $uid = $facebook-&gt;getUser(); $me = $facebook-&gt;api('/me'); } catch (FacebookApiException $e) { error_log($e); } } </code></pre> <p>$uid is just an integer, and <code>$me</code> is the data for the current user (which it sounds like you don't need). The same data could be retrieved by calling:</p> <pre><code>$me = $facebook-&gt;api('/' . $uid); //Generates https://graph.facebook.com/[uid] </code></pre> <p>The problem I have right now with the example is that the curl function inside the Facebook class (<code>makeRequest</code> method) is for some reason returning NO content. So, <code>$me</code> is ending up with nothing, which makes the example still say <em>"You are not connected".</em> But, if you were to output <code>$uid</code>, you would see that it does indeed contain the current user's ID.</p>

    1. CODoes it store it in a cookie by itself or do i need to specifically run a function to do this? I have set cookie to true when declaring the facebook class but on inspecting the cookies in Firefox it doesn't appear to have stored anything.

    2. CO@briggins5 It looks like it does it when you call `getSession`.

    3. COI have called <code>$facebook->getLoginUrl()</code> and <code>getSession</code> but still no cookies are stored, apart from some under the Facebook category, but these don't appear related specifically, and probably wouldn't be anyway.

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.
