    <p>I have come to the conclusion that the most probable reason that you are getting <code>NULL</code> values is that you are trying to execute PHP within <code>cgi-bin</code> which is mostly used/reserved for <code>.pl</code> or <code>.cgi</code> scripts. <strong>(PERL/CGI)</strong> – <code>.php</code> scripts will not execute under this folder.</p> <p>Having tested your code with the fixed named inputs, and testing under <code>cgi-bin</code> produced the same results.</p> <p>Move your <code>register.php</code> file outside of your <code>cgi-bin</code> and place it under <code>public_html</code> or sub-folder of your choice with the following code:</p> <p>(Copy/paste exactly as shown and use inside the same folder under public html and not cgi-bin)</p> <h2>HTML form</h2> <pre><code>&lt;form action="register.php" method="POST"&gt; &lt;table border="0"&gt; &lt;tr&gt; &lt;td&gt; &lt;label for="username"&gt; New Username: &lt;/label&gt; &lt;/td&gt; &lt;td&gt; &lt;input type="text" id="username" name="username"/&gt; &lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt; &lt;label for="password"&gt; New Password: &lt;/label&gt; &lt;/td&gt; &lt;td&gt; &lt;input type="password" id="password" name="password" /&gt; &lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt; &lt;input type="submit" value="Submit"&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; &lt;/form&gt; </code></pre> <h2>PHP handler</h2> <pre><code>&lt;?php $user = $_POST['username']; $pass = $_POST['password']; $encrypted_pass = md5($pass); //... insert terrible code here ... var_dump($user); var_dump($pass); ?&gt; </code></pre>

Guidance
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).
