Body
<p>That code could be looked like this:</p> <pre><code><?php include('connect.php'); $result = mysql_query("SELECT DISTINCT category FROM categories") or die(mysql_error()); while ($row = mysql_fetch_array($result)) { echo "<div>"; echo "<h2 class='title'>" . $row['category'] . "</h2>"; echo "<p>"; echo "<ul class='links'>"; $result1 = mysql_query("SELECT * FROM categories WHERE category = {$row['category']}") or die (mysql_error()); while ($row1 = mysql_fetch_array($result1)) { echo "<li><a href='" . $row1['sub_category_href'] . " target='_top'>" . $row1['sub_category'] . "</a></li>"; } echo "</ul>"; echo "</p>"; echo "</div>"; } ?> </code></pre> <p>But I suggest you to optimize in this manner:</p> <pre><code><?php include('connect.php'); $result = mysql_query("SELECT * FROM categories") or die(mysql_error()); $cats = array(); while ($row = mysql_fetch_array($result)) { $category = $row['category']; $sub_category = $row['sub_category']; $sub_category_href = $row['sub_category_href']; $cat_hrefs[$category][$sub_category] = $sub_category_href; } foreach ($cat_hrefs as $category => $sub_category_hrefs) { echo "<div>"; echo "<h2 class='title'>" . $category . "</h2>"; echo "<p>"; echo "<ul class='links'>"; foreach ($sub_category_hrefs as $sub_category => $sub_category_href) { echo "<li><a href='" . $sub_category_href . " target='_top'>" . $sub_category . "</a></li>"; } echo "</ul>"; echo "</p>"; echo "</div>"; } ?> </code></pre> <p>You do not need to make three queries, because you can do it in one query, which is more optimal.</p>

Querying!

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.
