Php url parameters

Question

I wanted to add url parameters to the spry menu bar widget such that they show posts with specific values like categories_id are the unique identifiers of my categories and I have added them to my post database too so I need the page to show the posts who's categories_id =1 so that all the posts under the templates category are visible only I am able to achieve this but for that I am having to create seperate pages for each category so is there any way to add such a code in the url parameter plz give a similar code's example.
Thankyou in advance.

<?php require_once('Connections/database_rfs.php'); ?>
<?php
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "")
  if (PHP_VERSION < 6) {
    $theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;
  $theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);
  switch ($theType) {
    case "text":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;   
    case "long":
    case "int":
      $theValue = ($theValue != "") ? intval($theValue) : "NULL";
      break;
    case "double":
      $theValue = ($theValue != "") ? doubleval($theValue) : "NULL";
      break;
    case "date":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;
    case "defined":
      $theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;
      break;
  return $theValue;
$maxRows_Recordset1 = 15;
$pageNum_Recordset1 = 0;
if (isset($_GET['pageNum_Recordset1'])) {
  $pageNum_Recordset1 = $_GET['pageNum_Recordset1'];
$startRow_Recordset1 = $pageNum_Recordset1 * $maxRows_Recordset1;
$colname_Recordset1 = "-1";
if (isset($_GET['categories_id'])) {
  $colname_Recordset1 = $_GET['categories_id'];
mysql_select_db($database_database_rfs, $database_rfs);
$query_Recordset1 = sprintf("SELECT * FROM posts WHERE categories_id = %s ORDER BY date_posted DESC", GetSQLValueString($colname_Recordset1, "int"));
$query_limit_Recordset1 = sprintf("%s LIMIT %d, %d", $query_Recordset1, $startRow_Recordset1, $maxRows_Recordset1);
$Recordset1 = mysql_query($query_limit_Recordset1, $database_rfs) or die(mysql_error());
$row_Recordset1 = mysql_fetch_assoc($Recordset1);
