Body
To begin with, the code inside the while loop is not valid PHP so the script will definitely not run as posted. What you need to do is either mark that code as non-PHP (i.e. HTML markup by closing the PHP script tag after the while loop and reopening before the end of the while) or use an output mechanism such as the <code>echo</code> function in PHP. Here's how you could rewrite the while loop using echo: <pre><code>while ($row = mysql_fetch_array($result)) { echo(" From: ".$row['from']." "); echo("Date: ".$row['date']." at ".$row['time']." "); echo($row['message']); echo(" <HR>"); } </code></pre> As far as the delete button, you could add that to your page as an HTML input element of type submit, and place it inside an HTML <code>form</code> element. When the user clicks the button then, the form will do perform a an HTTP POST, or GET (depending on the <code>method</code> attribute you put on the <code>form</code> element). The page it POSTs or GETs is controlled by yet another attribute of the <code>form</code> element, named <code>action</code>. Here's an example: <pre><code> <form id='frmMessageView' name='frmMessageView' method='POST' action='delete_message_script.php'> <input id='btnDelete' name='btnDelete' type='submit' value='Delete Message' /> </form> </code></pre> In the example above, when the user clicks the button that says "Delete Message" the browser will perform a POST HTTP request to the delete_message_script.php script. You may wish to read more about HTML form elements, and how a form works (i.e. difference between a POST and a GET request, request variables, and the different types of input elements; also, read about how PHP allows you to process HTTP request variables). In the PHP script that the form posts to you may need to track which button the user clicked to get there (if there is more than one) and which message needs to be deleted. Finally, once you get the idea, read about form post-back. That is the mechanism of posting back to the same page (script).

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.
