    <p>Well, the title is probably not very helpful. I'm not sure how to describe this error. I'm sure it's caused by something stupid on my part. For the life of me though, I can't figure it out.</p> <p>Here's what I'm trying to do: There's a list of folders in my directory "img/gallery"</p> <p>Within each of those folders are images</p> <p>There's also a folder called "img/thumbs" which is structured exactly the same but with thumbnail images</p> <p>I am writing a script that does two things: it displays the names of the folders within "img/gallery" and displays a list of thumbnails with links to the images in that folder.</p> <p>These two components, when run separately, work fine. Put together, I get an error at</p> <p><code>if ($handle = opendir('img/gallery/$file/'))</code></p> <p>saying that $file is not a valid directory. </p> <p>Here's the code:</p> <p>` <pre><code>if ($handle = opendir('img/gallery/')) { $blacklist = array('.', '..', 'somedir', 'somefile.php'); while (false !== ($file = readdir($handle))) { if (!in_array($file, $blacklist)) { echo "&lt;h2&gt;$file&lt;/h2&gt;\n"; } } closedir($handle); } echo "&lt;P class='gallery'&gt;\n"; if ($handle = opendir('img/gallery/$file/')) { while (false !== ($entry = readdir($handle))) { if ($entry != "." &amp;&amp; $entry != "..") { echo "&lt;a class='fancybox' href='img/gallery/$file/$entry' data-fancybox-group='gallery'&gt;\n&lt;img src='img/thumbs/$file/$entry' alt='' /&gt;&lt;/a&gt;\n"; } } echo "&lt;/p&gt;\n"; closedir($handle); } </code></pre> <p>`</p> <p>And advice would be wonderfully helpful. Thanks!</p>

    1. COTry it this way: `if ($handle = opendir("img/gallery/$file/"))` A common problem is that the normal quotes ' ' will not display the variables so it will just search for a directory named $file which it will obviously not find.

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.
