    <p>The first dropdown box will be populated when the page loads based on values from a database. The second dropdown box should display a set of values based on the selection from the first dropdown box. I know there have been similar questions asked on here before, but I haven't found a solution that matches my scenario.</p> <p>UI code:</p> <pre><code>&lt;tr&gt; &lt;td&gt;&lt;label for="taProj"&gt;&lt;?php echo t('Project')?&gt;:&lt;/label&gt;&lt;/td&gt; &lt;td&gt;&lt;select name="taProj" id="taProj" onchange= "get_module()"&gt; &lt;option value="" &gt;-------------------------&lt;/option&gt; &lt;?php foreach ($tap as $row){?&gt; &lt;option value="&lt;?php echo $row['proj_id']; ?&gt;" &gt;&lt;?php echo $row['proj_name'];?&gt;&lt;/option&gt; &lt;?php } ?&gt; &lt;/select&gt;&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;&lt;label for="taModule"&gt;&lt;?php echo t('Module Name')?&gt;:&lt;/label&gt;&lt;/td&gt; &lt;td&gt;&lt;select name="taModule" id="taModule" &gt; &lt;option value="" &gt;-------------------------&lt;/option&gt; &lt;?php foreach ($tam as $row){?&gt; &lt;option value="&lt;?php echo $row['mod_id']; ?&gt;" &gt;&lt;?php echo $row['mod_name'];?&gt;&lt;/option&gt; &lt;?php } ?&gt; &lt;/select&gt;&lt;/td&gt; &lt;/tr&gt; &lt;script type="text/javascript"&gt; function get_module(){ var projid = document.getElementById('taProj').value; alert(projid); } &lt;/script&gt; </code></pre> <p>mycontroller.php</p> <pre><code>public function sample(){ echo $_GET['projid']; } </code></pre> <p>its working properly..

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).
