    <p>I have some code which retrieves user comments from my database:</p> <pre><code>$comments = mysql_query("SELECT * FROM comments WHERE ref = '$theID'LIMIT 0, 3;") or die(mysql_error()); while ($rowC = mysql_fetch_array($comments)) { echo "&lt;p&gt;On " .$rowC['date']. ", "; echo $rowC['username']. " said: &lt;br/&gt;"; echo $rowC['comment']; echo "&lt;/p&gt;&lt;hr/&gt;"; } if (mysql_num_rows($comments) == 0) { echo "&lt;p&gt;(No comments have been made yet)&lt;/p&gt;"; } </code></pre> <p>Comments are stored with a unique user reference in the database, and retrieved where they match the user id, this is called at the top of the page:</p> <pre><code>$theID = $_GET['id']; </code></pre> <p>What I am trying to do is limit the comments shown, and if there are more than 3, show a 'click to see more' type button or link which displays all the user comments on the same page in the same way as above. </p> <p>UPDATE, i am now using this, Trying to implement Johan's suggestion, but still cant get it to display more when link is clicked: </p> <pre><code> $comments = mysql_query("SELECT * FROM comments WHERE ref = '$theID' LIMIT 0, 4") or die(mysql_error()); while ($rowC = mysql_fetch_array($comments)) { echo "&lt;p&gt;On " .$rowC['date']. ", "; $username = htmlspecialchars($rowC['username']). " said: &lt;br/&gt;"; echo $username; $comment = htmlspecialchars($rowC['comment']); echo $comment; echo "&lt;/p&gt;&lt;hr/&gt;"; } $num_rows = mysql_num_rows($result); if ($num_rows &gt; 3) { $query = "SELECT * FROM comments WHERE ref = '$theID' LIMIT 4, 20"; } echo "&lt;p&gt;&lt;a href=''&gt;click to see more&lt;/a&gt;&lt;/p&gt;"; if (mysql_num_rows($comments) == 0) { echo "&lt;p&gt;(No comments have been made yet)&lt;/p&gt;"; } </code></pre>

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.
