Select from a menu a listing from a database?

<?php

# Set page title and display header section.
$page_title = 'database' ;
include ( 'includes/header.html' ) ;

# Open database connection.
require ( 'connect_db.php' ) ;


$q = "SELECT * FROM forum" ;
$r = mysqli_query( $dbc, $q ) ;
if ( mysqli_num_rows( $r ) > 0 )
{
  echo '<table><tr><th>Posted By</th><th>Subject</th><th id="msg">Message</th></tr>';
  while ( $row = mysqli_fetch_array( $r, MYSQLI_ASSOC ))
  {
    echo '<tr><td>' . $row['first_name'] .' '. $row['last_name'] . '<br>'. $row['post_date'].'</td>
    <td>' . $row['subject'] . '</td><td>' . $row['message'] . '</td> </tr>';
  }
  echo '</table>' ;

I would like to select one row list of the following. As this old example displays a bunch of rows, so a drop down menu would individual select one item from the sql. Can I do that with this example, is it complicated to do so?

 

 

[phpuserlogin]

$q = "SELECT * FROM forum" ;
$r = mysqli_query( $dbc, $q ) ;
if ( mysqli_num_rows( $r ) > 0 )
{
  echo '<table><tr><th>Posted By</th><th>Subject</th><th id="msg">Message</th></tr>';
  while ( $row = mysqli_fetch_array( $r, MYSQLI_ASSOC ))
  {
    echo '<tr><td>' . $row['first_name'] .' '. $row['last_name'] . '<br>'. $row['post_date'].'</td>
    <td>' . $row['subject'] . '</td><td>' . $row['message'] . '</td> </tr>';
  }
  echo '</table>' ;
}

So row Posted by, do I make a link in order to select that column, or use a drop down. to select a specific row for the data. Posted by is just an example. Record data 1, a very basic example is just what I'm trying to tinker with, with this code. Subject and so on.

I've updated it, so it just displays the words in the subject row from the sql.

So Playstation 2 model no would be selected from the actual subject row, via link, and a drop down menu would be the select method.

I've solved the display of the data.

How do I create a link to select subject row or what ever.

It isn't the link, it is the drop down menu.

I was thinking of the old drop downs before Html 5.😐
