    <p>Here's my test case. If the form is posted, a 500 error response is sent. If not, the form is sent.</p> <p>If the file input tag is commented out, the error handler is called. If the file input tag is present, the error handler isn't called. I think this might have something to do with the fact that jQuery needs to use an iframe to handle the upload and iframes <a href="http://api.jquery.com/error/#comment-34139831" rel="nofollow noreferrer">don't seem to respond to the error handler</a>.</p> <p>Edit: If I add <code>iframe: true</code> to the options passed to <code>ajaxSubmit</code> to force the use of an iframe, the non-file-upload case stops working also, so it definitely has to do with the iframe.</p> <p>Edit2: I'm using the <a href="http://jquery.malsup.com/form/" rel="nofollow noreferrer">jQuery Form Plugin</a>.</p> <pre><code>&lt;?php if($_SERVER['REQUEST_METHOD'] == 'POST') { header('HTTP/1.1 500 Internal Server Error'); die; } else {?&gt; &lt;html&gt;&lt;head&gt; &lt;script type='text/javascript' src='http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js?ver=2.9.2'&gt;&lt;/script&gt; &lt;script type='text/javascript' src='http://github.com/malsup/form/raw/master/jquery.form.js?v2.43'&gt;&lt;/script&gt; &lt;script type="text/javascript"&gt; jQuery(document).ready(function() { jQuery('a').click(function() {jQuery('form').ajaxSubmit({error: function(){alert('error handler called');}})}); }); &lt;/script&gt; &lt;/head&gt;&lt;body&gt; &lt;form method="POST"&gt; &lt;input type="text" name="mytext" /&gt; &lt;input type="file" name="myfile" /&gt;&lt;!-- comment this element out --&gt; &lt;input type="hidden" name="blah" value="blah" /&gt; &lt;a&gt;submit&lt;/a&gt; &lt;/form&gt; &lt;/body&gt;&lt;/html&gt; &lt;?php } </code></pre> <p>Is there any way to get the error handler to be called in both situations?</p>

    1. COWhat exactly is "ajaxSubmit"? Is that a plugin or something? Your own code? It's not in jQuery 1.4.2.

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.

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