    <p>Ok guys, I figured out the answer, it turns out that my i variable was the number of files each time I called it, since by the time the files had finished loading, all the requests had been initialized, here is the fixed code.</p> <pre><code>&lt;!DOCTYPE html&gt; &lt;html&gt; &lt;head&gt; &lt;title&gt;Multiple DnD Uploader&lt;/title&gt; &lt;link rel="stylesheet" href="style.css" /&gt; &lt;script type = "text/javascript" src = "../music/jquery.js"&gt;&lt;/script&gt; &lt;script type="text/javascript"&gt; $(document).ready(function(){ $('#drop').change(function(event){ files = event.target.files; $('#drop').css('display', 'none'); for(var i = 0, len = files.length; i &lt; len; i++) { file = files[i]; if((file.fileName+"").substring((file.fileName+"").length-4,(file.fileName+"").length)=='.mp3'){ $.ajax({ type: "POST", url: "uploader.php?id="+i, contentType: "multipart/form-data", headers: { "X-File-Name" : file.fileName, "X-File-Size" : file.fileSize, "X-File-Type" : file.type }, beforeSend: function() { $('#info').append('&lt;li class="indicator"&gt;&lt;span class="label"&gt;File Name :&lt;/span&gt; '+file.fileName+' | &lt;span class="label"&gt;Size :&lt;/span&gt; ' + file.fileSize + ' | &lt;img id="item'+i+'" src="loading.gif" /&gt;&lt;/li&gt;'); }, processData: false, data: file, success: function(data){ $('#item'+data).attr('src', 'check.png'); },error: function(data){ $('#info').append('Error: ' + data + '&lt;br /&gt;'); } }); }else{ $('#info').append('Error: Incorrect file type. Looking for .mp3'); } } }); }); &lt;/script&gt; &lt;/head&gt; &lt;body&gt; &lt;div id="drop"&gt; &lt;h1&gt;Drop files here&lt;/h1&gt; &lt;p&gt;To add them as attachments&lt;/p&gt; &lt;input type="file" multiple="true" id="filesUpload" /&gt; &lt;/div&gt; &lt;div id="info"&gt; &lt;/div&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>Note, the uploader.php file, upon completion of uploading, echoes <code>$_GET['id']</code> back to the ajax call, which is then used to change that list item's image.</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.

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).
