    <p>I'm building an audio player that makes 3 different API calls, and I need them all to be in JSONP format, so I made a PHP proxy file that determines the output of the JSON data like so:</p> <pre><code>$datatype = $_GET["type"]; $artist = urlencode($_GET["artist"]); $album = urlencode($_GET["album"]); $content = ""; if($datatype == 'albumart'){ $content = file_get_contents('http://ws.audioscrobbler.com/2.0/?method=album.getinfo&amp;api_key=037358e302c80571663e6a7a66b1dc05&amp;artist=' . $artist . '&amp;album=' . $album . '&amp;format=json'); } elseif($datatype == 'artistart'){ $content = file_get_contents('http://ws.audioscrobbler.com/2.0/?method=artist.getinfo&amp;api_key=037358e302c80571663e6a7a66b1dc05&amp;artist=' . $artist . '&amp;autocorrect=1&amp;format=json'); } else { $content = file_get_contents('http://cjzn.streamon.fm/metadata/recentevents/CJZN-48k.json'); } header('Content-type: application/json; charset=utf-8'); echo $_GET['callback'] . '(' . json_encode($content) . ')'; </code></pre> <p>Upon testing the output it seems to work fine, it gets the respective API data, wraps it in the JSONP <code>()</code> and accepts a JSONP callback.</p> <p>Bur when I try and use it in my Javascript file it doesn't seem to work, but I can't figure out why! Here's an example of one of the functions being used to call the JSON data:</p> <pre><code>function getAlbumArt(artist,album){ var dataArtist = artist, dataAlbum = album, albumArtURL; $.ajax({ url: 'jsonproxy.php', dataType: 'jsonp', data: { type: 'albumart', artist: dataArtist, album: dataAlbum }, success: function(data) { if(data.album.image[4]["#text"]){ var albumArtURL = data.album.image[4]["#text"]; $('section.player div.album-artwork').css({'background-image':'url("' + albumArtURL + '")'}); } else { getArtistArt(dataArtist); } }, error: function() { getArtistArt(dataArtist); alert('Sorry, unable to retrieve album artwork!'); } }); } </code></pre> <p>Can anyone help with why this doesn't work for me?</p> <p><strong>Edit</strong></p> <p>I did <code>alert(data);</code> on <code>success</code>, and that returned all of the data from the feed, after that if I did something more specific like <code>alert(data.album.image[4]["#text"]);</code> it returned <code>undefined</code>. Very confused here. Anyone have any thoughts?</p>

    3. COIn lieu of the console I did a good old `alert` to alert some of the data when the function ran, and the alert returned undefined. This makes me think it's something with the PHP file or my Ajax request in jQuery. Just not sure where, I've looked over and over

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
