problem with session variable and while loop

[steviecee]

I'm trying to work out a way to do the following, and I'm stumped! I'm querying a database and I'm using a while loop to display the data, at the end of every run through of the while loop I'm saving one of the returned fields in a session variable, to be passed to another page. The problem is that the session variable always sets itself to the value of the last run through, so it just passes one value to the next page, how can I set it up to pass all the values through?
code is:

[code]
$result = mysqli_query($conn, "select * from pm where userToID = 'steviece'");

while ($row = mysqli_fetch_array($result))
{
    echo "<tr>";
echo "<td>".$row['pmID']."</td>";
echo "<td>".$row['pmTopic']."</a></td>";
echo "<td>".$row['userID']."</td>";
echo "<td>";
$pmID = $row['pmID'];

session_start();
$_SESSION["messID"] = $pmID;
echo "<a href='viewMess.php'>View Message</a>";

echo "</td>";
echo "</tr>";
}
[/code]

Cheers

Actually the above question isn't strictly right. the session variable needs to pass the data of whatever row is selected, so if someone clicked the second row of the the table that data would be sent via the session variable  ::)
