    <p>I know I can loop through the playlists to compare if the playlist exists on Youtube but that is making two calls (example below) and since I already know the playlist ID I should just be able to make one call.</p> <p>Two calls to YouTube to loop through playlists (not the way I want to do it):</p> <pre><code># Playlist ID from URL $playlist=$_GET['playlist']; # Playlists from YoUtube $playlists=$yt-&gt;PlaylistsListFeed(); # Loop through the playlists. foreach($playlists as $playlist_feed) { if($playlist_feed['id']==$playlist) { # This is a playlist $this-&gt;setIsPlaylist(TRUE); # Assign the Playlist Items to a variable. $video_search=$yt-&gt;PlaylistItems($playlist_feed['id']); break; } } # If $video_search is not set then playlist does not exist. if(!isset($video_search)) { return $display='That playlist doesn\'t exist. Please choose another.'; } </code></pre> <p>I have the code working for the single call but I can't figure out how to get the 404 error it returns if the playlist ID does not exist (results from YouTube below).</p> <p>YouTube method (<code>PlaylistItems</code>):</p> <pre><code>/** * PlaylistItems * * Retrieves videos from a playlist. * * @param int $playlist_id The ID of the playlist. * @param string $part The part parameter specifies a comma-separated list of * one or more playlistItem resource properties that the API * response will include. The part names that you can include * in the parameter value are id, snippet, and contentDetails. * @access public */ public function PlaylistItems($playlist_id, $part='snippet') { # Set the Database instance to a variable. $doc=Document::getInstance(); try { # Bring $youtube_service into the scope global $youtube_service; $playlistsItems_optParams=array('maxResults' =&gt; 50, 'playlistId' =&gt; $playlist_id); $playlistsItems=$youtube_service-&gt;playlistItems-&gt;listPlaylistItems($part, $playlistsItems_optParams); $new_array=$this-&gt;rebuildArray($playlistsItems, TRUE); # Instantiate a new Utility object. $utility=new Utility(); # Sort the playlist array by date. $items=$utility-&gt;sortByDate($new_array, 'publishedAt'); return $items; } catch(Exception $e) { # Print Results (below) print_r($e); exit; if($e-&gt;getCode()==404) { $doc-&gt;setError('That playlist doesn\'t exist.

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.
