I'm php newbie and I"m trying to create pagination for some DP results and I'm having some problems. I can view the pagination at the bottom of my DB results, however when I click on the numbers I remain on the same page.  I'm using this 7 step pagination script: http://www.phpeasystep.com/phptu/29.html and I think my problem may be within step 7, im confused on what to do for that step, but it could be something else. I don't deal with code that often so this new to me. So my question is how do I get this script to work?

 


<?php require_once('Connections/myconnectboi.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;
}
}

$currentPage = $_SERVER["PHP_SELF"];

$maxRows_Recordset2 = 4;
$pageNum_Recordset2 = 0;
if (isset($_GET['pageNum_Recordset2'])) {
  $pageNum_Recordset2 = $_GET['pageNum_Recordset2'];
}
$startRow_Recordset2 = $pageNum_Recordset2 * $maxRows_Recordset2;

mysql_select_db($database_myconnectboi, $myconnectboi);
$query_Recordset2 = "SELECT * FROM hiphop ORDER BY id DESC";
$query_limit_Recordset2 = sprintf("%s LIMIT %d, %d", $query_Recordset2, $startRow_Recordset2, $maxRows_Recordset2);
$Recordset2 = mysql_query($query_limit_Recordset2, $myconnectboi) or die(mysql_error());
$row_Recordset2 = mysql_fetch_assoc($Recordset2);

if (isset($_GET['totalRows_Recordset2'])) {
  $totalRows_Recordset2 = $_GET['totalRows_Recordset2'];
} else {
  $all_Recordset2 = mysql_query($query_Recordset2);
  $totalRows_Recordset2 = mysql_num_rows($all_Recordset2);
}
$totalPages_Recordset2 = ceil($totalRows_Recordset2/$maxRows_Recordset2)-1;

$queryString_Recordset2 = "";
if (!empty($_SERVER['QUERY_STRING'])) {
  $params = explode("&", $_SERVER['QUERY_STRING']);
  $newParams = array();
  foreach ($params as $param) {
    if (stristr($param, "pageNum_Recordset2") == false && 
        stristr($param, "totalRows_Recordset2") == false) {
      array_push($newParams, $param);
    }
  }
  if (count($newParams) != 0) {
    $queryString_Recordset2 = "&" . htmlentities(implode("&", $newParams));
  }
}
$queryString_Recordset2 = sprintf("&totalRows_Recordset2=%d%s", $totalRows_Recordset2, $queryString_Recordset2);
