    <p><code>file_get_contents</code> doesn't take the "r" parameter - see <a href="http://ie2.php.net/file_get_contents" rel="nofollow noreferrer">the PHP manual page</a>:</p> <pre><code>string file_get_contents ( string $filename [, int $flags...) </code></pre> <p>Valid <code>$flag</code> values are <code>FILE_USE_INCLUDE_PATH, FILE_TEXT, FILE_BINARY</code>.</p> <p>Try removing the "r" flag and trying again</p> <p><strong>Edit</strong> - question updated, "r" flag was being ignored so evidently not the root of the problem. </p> <p>It looks like there's a <a href="http://bugs.php.net/bug.php?id=33359" rel="nofollow noreferrer">reported bug in PHP</a> regarding <code>file_get_contents</code> returning an empty string for a HTTP POST. From the bug description:</p> <blockquote> <p><code>file_get_contents('php://input')</code> (and also <code>file, fopen+fread</code>) does not return POST data, when submited form with enctype="multipart/form-data".</p> <p>When submited the same form without enctype specified (so default "application/x-www-form-urlencoded" is used) all works OK.</p> </blockquote> <p>So it looks like a work-around is to change the specified form enctype away from <code>multipart/form-data</code>, which obviously isn't ideal for an image upload - from the <a href="http://www.w3.org/TR/html401/interact/forms.html" rel="nofollow noreferrer">W3 FORM specification</a>:</p> <blockquote> <p>The content type "application/x-www-form-urlencoded" is inefficient for sending large quantities of binary data or text containing non-ASCII characters. The content type "multipart/form-data" should be used for submitting forms that contain files, non-ASCII data, and binary data.</p> </blockquote> <p><strong>Further Edit</strong></p> <p>This bug seems to have been resolved in your PHP version. Have you checked to make sure that the buffer being read in doesn't start with a carriage-return / newline char? There's a problem somewhat similar to yours that was discussed <a href="http://www.sitepoint.com/forums/showthread.php?t=555002" rel="nofollow noreferrer">on Sitepoint</a>.</p> <p>Try running <a href="http://ie2.php.net/strlen" rel="nofollow noreferrer"><code>strlen</code></a> on the input and see what the length is.</p>

    3. COThis is a curly one! :) That bug is old, and I've confirmed that it's fixed by changing the request method to POST, and it's working fine. My problem is _only_ with the PUT method.

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).
