Hi.

I am trying to create a discussion board where you can click on the title of a post (from a list of many) to be taken to a page where only the post the user clicked on is displayed. I then want to put comments underneath.

However, I cant figure out how to display just 1 record instead of all of them in the database. (I think that is because of the array).

This is the code I have. it displays all the records in the database table instead of just showing 1.

<?php
		//connect to database
			require_once ('dbconnect.php');
$displayPosts = "select postID, postDate, postName, postTitle, postBody from pmf_discussion
                order by PostDate";
                $rsAllPosts = mysql_query($displayPosts);
                echo "<table id=\"posts\" border=\"1\">\n";
                while ($Post = mysql_fetch_array($rsAllPosts)){
                    $postID = $Post['postID'];
                    $postDate = $Post['postDate'];
                    $postName = $Post['postName'];
                    $postTitle = $Post['postTitle'];
		    $postBody = $Post['postBody'];
 
                    echo "<tr>
						<td>$postName</td>
						<td>$postBody</td>
					</tr>";
                }
                echo "</table>\n";
            ?>
