    <p>I have just started making a new Facebook app hosted on heroku and I haven't made any changes yet, but tested the functionality a little bit, to get used to how stuff works. All good until I try the "send message button", to which a dialog appears with the following error log:</p> <pre><code>An error occurred. Please try later API Error Code: 100 API Error Description: Invalid parameter Error Message: 'link' is invalid. </code></pre> <p>I've looked a bit in the related piece of code, and I find nothing wrong, but I am quite new so maybe any of you can help me a little bit to find out what's wrong:</p> <pre><code> $('#sendToFriends').click(function() { FB.ui( { method : 'send', link : $(this).attr('data-url') }, function (response) { // If response is null the user canceled the dialog if (response != null) { logResponse(response); } } ); }); </code></pre> <p>The reason I don't think there is a problem with <code>$(this).attr('data-url');</code> is that the following works (the post to wall button):</p> <pre><code> $('#postToWall').click(function() { FB.ui( { method : 'feed', link : $(this).attr('data-url') }, function (response) { // If response is null the user canceled the dialog if (response != null) { logResponse(response); } } ); }); } </code></pre> <p>The <code>getUrl()</code> function that gets the value is:</p> <pre><code> public static function getUrl($path = '/') { if (isset($_SERVER['HTTPS']) &amp;&amp; ($_SERVER['HTTPS'] == 'on' || $_SERVER['HTTPS'] == 1) || isset($_SERVER['HTTP_X_FORWARDED_PROTO']) &amp;&amp; $_SERVER['HTTP_X_FORWARDED_PROTO'] == 'https' ) { $protocol = 'https://'; } else { $protocol = 'http://'; } return $protocol . $_SERVER['HTTP_HOST'] . $path; </code></pre> <p>}</p> <p>Can anyone please help me? I've searched a bit on facebook developers forum and on stackoverflow, but the although the error code was the same, the error message was different. I think this problem is from facebook since method <code>feed</code> works, while method <code>send</code> does not. Both methods are defined in the facebook sdk </p> <p>Note:I am using the latest php sdk</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.
