drop down preselect

[onthespot]

Ok if you could help me with this, i would be grateful.

So I have a dropdown menu on my messaging system with all the site users.

I want to be able to click a link on the user profile called "PM Me".

Then that bring up the send message page but with the username of the users profile you are messaging already selected on the drop down.

 

This would also be useful for replying to messages sent to you.

 

Could any offer some help on this, I really don't know where to start. Thankyou

$selectUsername = !empty($_GET['username']) ? $_GET['username'] : null;
..
$query = 'SELECT id, username FROM users';
$result = mysql_query($query, $db); // $db = mysql_connect()
$htmlSelect = '<select name="users">';
while (list($id, $username) = mysql_fetch_array($result, MYSQL_NUM)) {
    $selected = !strcmp($username, $selectUsername) ? ' selected="selected"' : '';
    $htmlSelect .= "<option value=\"$id\"$selected>$username</option>";
}
$htmlSelect .= '</select>';

 

<form action="" method="post">
   <label>Users: <?php print $htmlSelect; ?></label>
</form>

Thanks for the reply, but could you explain it a little bit. If i just click send message, will it just start at the top of the users list, so say A, as normal?

if ?username=someUsername then it will pre-select the user from the list otherwise it will not.
