php extract from array/query and define php session variable by row without overwriting

I have a mySQL database that is queried and displayed in tables in index.php. I have a file called up.php that handles a click on an < a > in each table that is output from the query in index.php. I need to have a variable that I can extract from a field in each seperate row that is queried, so that when the < a > is clicked it passes the variable to the up.php file to be manipulated. Right now the variable is just being over written and is equal to the value of the last row queried and the database is updated frequently, so I can't just set one to each row, it has to be dynamic.

Here is the index.php file

<?php
$sql = mysql_query("SELECT * FROM blogData ORDER BY id DESC");
//query for even numbered rows where mes_id = even
$sql2=mysql_query("SELECT * FROM messages WHERE mod(mes_id,2) = 0 ORDER BY mes_id DESC");
//query for odd numbered rows where mes_id = even
$sql3=mysql_query("SELECT * FROM messages WHERE mod(mes_id,2) = 1 ORDER BY mes_id DESC");

while(($row = mysql_fetch_array($sql))AND($row2 = mysql_fetch_array($sql2))AND($row3 = mysql_fetch_array($sql3)) ){
$id = $row['id'];
$title = $row['title'];
$content = $row['content'];
$category = $row['category'];
$podcast = $row['podcast'];
$datetime = $row['datetime'];


$message1=$row2['msg'];

//******* this is the variable from the query that needs to be held and not overwritten ********
$mes_id1=$row2['mes_id'];

$totalvotes1=$row2['totalvotes'];

$message2=$row3['msg'];

//******* this is the second variable from the query that needs to also be held and not overwritten *******
$mes_id2=$row3['mes_id'];

$totalvotes2=$row3['totalvotes'];

//attempting to implement this array...? not sure how to use it correctly...
$valuess[]=$row2['mes_id'];

//******* I was trying to use these session variables in up.php but they were being overwritten in the query ********
$_SESSION['message1'] = $row2['msg'];
$_SESSION['message2'] = $row3['msg'];
$_SESSION['mes_id1'] = $row2['mes_id'];
$_SESSION['mes_id2'] = $row3['mes_id'];
$_SESSION['totalvotes1'] = $row2['totalvotes'];
$_SESSION['totalvotes2'] = $row3['totalvotes'];
$_SESSION['valuess'] = $valuess[1];
?>

<?php
// variable used to display file name of $podcast without the extension
$noext = $podcast;
$echodub = rawurlencode($podcast);
// code to display $noext without the file extension
$info = pathinfo($noext);
$noext_name =  basename($noext,'.'.$info['extension']);
?>

<!--  ********* echo php variables in html format, in a table with the class of "podcast" -->

Thank you so much to anybody who is able to help me!
