    <p>i have a problem with my facebook canvas app that is currently on development i'm working on <a href="http://localhost:8080" rel="nofollow">http://localhost:8080</a></p> <p>my canvas url is <code>http://localhost:8080/fbcanvas/</code></p> <p>on facebook the url is set to <code>http://apps.facebook.com/app_name/</code></p> <p>the problem is i'm getting a code as an <code>$_GET['code']</code> variable after a user approves my app. in facebook documentation it doesnt say anything about getting a <code>$_GET['code']</code> it just says getting <code>signed_request</code></p> <p>this is the code i'm using from facebook examples.</p> <pre><code> require_once($_SERVER['DOCUMENT_ROOT'] . '/classes/Page.php'); require($_SERVER['DOCUMENT_ROOT'] . '/core/config.fb.php'); $canvas_page = 'http://apps.facebook.com/khawamusic/'; $auth_url = 'https://www.facebook.com/dialog/oauth?client_id=' . $app_id . '&amp;redirect_uri=' . urlencode($canvas_page); $signed_request = $_REQUEST['signed_request']; list($encoded_sig, $payload) = explode('.', $signed_request, 2); $data = json_decode(base64_decode(strtr($payload, '-_', '+/')), true); if(empty($data['user_id'])) { echo('&lt;script&gt; top.location.href="' . $auth_url .'";&lt;/script&gt;'); } else { $page = new Page; $styles = array('reset.css', 'fbcanvas.css'); $scripts = array( 'https://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js', 'https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.14/jquery-ui.min.js', 'http://connect.facebook.net/en_US/all.js#xfbml=1', '/sources/js/fbcanvas.js' ); $page-&gt;set_title('Khawa'); $page-&gt;set_styles($styles); $page-&gt;set_scripts($scripts); $page-&gt;start_page(); require($_SERVER['DOCUMENT_ROOT'] . '/fbcanvas/fb.tpl'); $page-&gt;end_page(); } </code></pre> <p>so what happens is a user approves my app then he gets redirected to <code>http://apps.facebook.com/khawamusic/?code=blabla</code></p> <p>i'm cnfused because in the documentation it doesn't say i'm suppose to get a <code>$_GET['code']</code></p>

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.
