    <p>I'm relatively new to this, so sorry if I'm posting in the wrong place. I've got a table in my database which holds 4 things - id, time put in and user and message (for a basic chat-room style thing). I'm trying to call these using a PHP page. But my page just gets returned blank when I put an argument in the address bar. I'm trying to call it so that only lines with a certain user in the user column get shown. My code is below - can anybody see what I am doing wrong? The URL of the file is <a href="http://freedom-apps.co.uk/chat/messages.php" rel="nofollow">http://freedom-apps.co.uk/chat/messages.php</a>. You see a load of entries - at the start, there is u m u m u m. U represents the user entered, m is the message. So I tried: <a href="http://freedom-apps.co.uk/chat/messages.php?user=u" rel="nofollow">http://freedom-apps.co.uk/chat/messages.php?user=u</a> which returns an error. Any ideas? My code is:</p> <pre><code>&lt;?php header( 'Content-type: text/xml' ); mysql_connect('localhost:/var/lib/mysql/mysql.sock', 'freedom_ASAPPS', '********'); mysql_select_db( 'freedom_chat_alpha' ); if ( $_REQUEST['user'] ) { $user = mysql_escape_string($_REQUEST['user']); $result = mysql_query('SELECT * FROM chatitems WHERE user = '$user' ORDER BY added LIMIT 50'); } else { $result = mysql_query('SELECT * FROM chatitems ORDER BY added LIMIT 50'); } ?&gt; &lt;chat&gt; &lt;?php while ($row = mysql_fetch_assoc($result)) { ?&gt; &lt;message added="&lt;?php echo( $row['added'] ) ?&gt;" id="&lt;?php echo( $row['id'] ) ?&gt;"&gt; &lt;user&gt;&lt;?php echo( htmlentities( $row['user'] ) ) ?&gt;&lt;/user&gt; &lt;text&gt;&lt;?php echo( htmlentities( $row['message'] ) ) ?&gt;&lt;/text&gt; &lt;/message&gt; &lt;?php } var_dump($result); mysql_free_result($result); ?&gt; &lt;/chat&gt; </code></pre> <p>I believe it is something wrong with line 6 and 7, or in the way I call the php page with the argument (see above). I've being referring to the book I have used to learn this stuff, and still can't figure it out (Learning PHP, MySQL, and JavaScript: A Step-by-Step Guide to Creating Dynamic Websites).</p> <p>Thanks, Sam</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.
