    <p>Maybe it's a dumb question, but I wasn't able to solve it myself.</p> <p>I have the following code:</p> <pre><code>&lt;?php $path = "galeria01"; $dir_handle = @opendir($path) or die("Not found: $path"); list_dir($dir_handle,$path); function list_dir($dir_handle,$path) { global $div; $div = 001; global $zindex; $zindex = 200; global $margem; $margem = 114; while ((($file = readdir($dir_handle)) !== false)) { if ($file != "." &amp;&amp; $file != ".." ) { echo PHP_EOL . '&lt;div id="'; echo str_pad($div, 3, 0, STR_PAD_LEFT); echo '" style="position:absolute;left:'; echo $margem; echo 'px;z-index:'; echo $zindex; echo '"&gt;&lt;img src="galeria01/'; echo $file; echo '" width="675" height="450" /&gt;&lt;/div&gt;'; echo'&lt;span class="clear"&gt;&lt;/span&gt;'; $div++; $zindex--; $margem = $margem - 675; } } } closedir($dir_handle); ?&gt; </code></pre> <p>As you can see, it read all files in a folder, and generates the following code:</p> <pre><code>&lt;div id="001" style="position:absolute;left:114px;z-index:200"&gt;&lt;img src="001.jpg" width="675" height="450" /&gt;&lt;/div&gt;&lt;span class="clear"&gt;&lt;/span&gt; &lt;div id="002" style="position:absolute;left:-561px;z-index:199"&gt;&lt;img src="002.jpg" width="675" height="450" /&gt;&lt;/div&gt;&lt;span class="clear"&gt;&lt;/span&gt; &lt;div id="003" style="position:absolute;left:-1236px;z-index:198"&gt;&lt;img src="003.jpg" width="675" height="450" /&gt;&lt;/div&gt;&lt;span class="clear"&gt;&lt;/span&gt; &lt;div id="004" style="position:absolute;left:-1911px;z-index:197"&gt;&lt;img src="004.jpg" width="675" height="450" /&gt;&lt;/div&gt;&lt;span class="clear"&gt;&lt;/span&gt;&lt;/div&gt; </code></pre> <p>I just need to re-run the code a few times and generate all those dinamically generated divs, in the same order again, but ALWAYS decreasing the left margin and z-index values, like this:</p> <pre><code> &lt;div id="001" style="position:absolute;left:114px;z-index:200"&gt;&lt;img src="001.jpg" width="675" height="450" /&gt;&lt;/div&gt;&lt;span class="clear"&gt;&lt;/span&gt; (...) &lt;div id="004" style="position:absolute;left:-1911px;z-index:197"&gt;&lt;img src="004.jpg" width="675" height="450" /&gt;&lt;/div&gt;&lt;span class="clear"&gt;&lt;/span&gt;&lt;/div&gt; &lt;div id="001" style="position:absolute;left:-2586px;z-index:196"&gt;&lt;img src="001.jpg" width="675" height="450" /&gt;&lt;/div&gt;&lt;span class="clear"&gt;&lt;/span&gt; (...) </code></pre> <p>How do I do that?</p> <p>I hope it's simple and that you can kindly help me.</p> <p>Thanks.</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).
