    <p>I am creating a questionnaire for a client that requires the questions to be organized by 3 layers of levels, with a unknown amount of questions and categories. I've successfully created the U.I. and the code to pull the information from the database however I've been trying to find out how to get everything loading in the right place. The database is organized like so by the client so I have no control over it:</p> <pre><code>id description parentId 1 Level 1 0 2 Level 2 0 3 Level 1a 1 4 Level 1b 1 5 Level 1a1 3 </code></pre> <p>and the code I'm using right now is this:</p> <pre><code>function printChildQuestions($parentid) { $sql="SELECT * FROM pB_test WHERE parentID=$parentid"; $result=mysql_query($sql); $i=0; while (true) { $row=mysql_fetch_array($result); if (!$row) break; if ($row['parentId'] == 0) { echo '&lt;div class="tabs"&gt;'; echo '&lt;span class="level1"&gt;'.$row['description'].'&lt;/span&gt;'; echo '&lt;ul id="main-nav"&gt;&lt;h2 align="center"&gt;Categories&lt;/h2&gt;&lt;/ul&gt;'; echo '&lt;div&gt;'.$row['id'].'&amp;nbsp;'.$row['description'].'&amp;nbsp;'.$row['parentId'].'&lt;/div&gt;'; if ($row['parentId'] == 1) { } echo '&lt;/div&gt;'; } else { echo '&lt;div&gt;'.$row['id'].'&amp;nbsp;'.$row['description'].'&amp;nbsp;'.$row['parentId'].'&lt;/div&gt;'; } printChildQuestions($row['id']); } } printChildQuestions(0); </code></pre> <p>and the html that needs to be generated for is here: <a href="http://jsfiddle.net/Cyb2N/" rel="nofollow">http://jsfiddle.net/Cyb2N/</a></p> <p>The issue is every idea I've come up with needs me to hardcode the levels in and breaks when level 2 is introduced. Could someone shove me in the right direction? 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.
