Loading data from database with pagination in PHP PDO - php

Question

I have a website developed using PHP PDO programming. In this website there is one page where the details of holiday packages is listed from database along with pagination. My problem is only 6 records from database is loading in the page, but the pagination shows more than one page. Actually I am using PDO for the first time and I can't manage this problem.
Here is my code
index.class (all database functions are written here)
<?php
include_once "class/common.php";
class INDEX {
var $doAction;
var $msg;
var $objScr;
var $objCommonFunc; // This is common function object.
var $rsltInfo; // A common result set used by this class in various queries.
var $rsltOp; // A common result set used by this class in various queries.
var $arrSysVar; // Array that stores the System Variable those are used in screen.
// Other variables
var $adminEmail;
var $arrMetaContent; // For storing content and meta information.
var $leftMenuId; // Recid of 'menugroup' table for managing leftbar.
var $rightMenuId; // Recid of 'menugroup' table for managing rightbar.
var $menuPos;
function getHolydays($rgnId,$start_from, $record_per_page){
$qrySel = "SELECT h.recid recid, h.regionid regionid, h.name name, h.subtitle subtitle, h.txtDays txtDays, h.txtNights txtNights, h.pricingfrom pricingfrom, h.thumb_img thumb_img
FROM holydays h";
if($rgnId!=0){ $qrySel.= " WHERE h.regionid=".$rgnId; }
$qrySel .=" LIMIT $start_from,$record_per_page";
$objDbResult = $this->rsltInfo->getResult($qrySel);
return $objDbResult;
}
function getHolydaysPagntnCount($rgnId){
$qrySel = "SELECT h.recid recid, h.regionid regionid, h.name name, h.subtitle subtitle, h.txtDays txtDays, h.txtNights txtNights, h.pricingfrom pricingfrom, h.thumb_img thumb_img
FROM holydays h";
if($rgnId!=0){ $qrySel.= " WHERE h.regionid=".$rgnId; }
//echo $qrySel ;
$objDbResult = mysql_query($qrySel);
return $objDbResult;
}
}
$objScr = new INDEX();
?>
international-holidays.php
<?php $active_menu = 'Holidays';
include_once("index.class.php");
include_once 'header.php';
$objScr = new INDEX();
//$region_name="";
//if($_REQUEST['mcId'])$mcId=$_REQUEST['mcId'];
$rgnId=0;
if($_REQUEST['rgnId'])$rgnId=$_REQUEST['rgnId'];
if($_REQUEST['pgId'])
$pgId=$_REQUEST['pgId'];
$start_from=!empty($_REQUEST['page'])?$_REQUEST['page']:0;
//echo $start_from;
$record_per_page=6;
$rsltrgn = $objScr->getRegionname();
$rsltsdrgn = $objScr->getRegionname();
$rsltholyDetails = $objScr->getHolydays($rgnId,$start_from, $record_per_page);
$holydetailscount = mysql_numrows($objScr->getHolydayscount());
$holydaycount = mysql_numrows($objScr->getHolydaysPagntnCount($rgnId));
$total_pages = ceil($holydaycount/$record_per_page);
$rsltbannerDets= $objScr->getbannerImg($rgnId);
$rowbannerdts = $rsltbannerDets->fetchAssoc();
?>

</div>
</div>
The same code works perfectly in other page. The thing is the pagination shows 5 pages, but when i click on any page for example 2, it doesn't load the 2nd page rather it shows the first page itself.
I didn't understand what is happening. This code has been developed by someone else and my task is to do some updates on this.
Can anyone please help me.. I really needed to get this done.

What about if you use this pluggin? In my case it was very helpfull.

Or you can just do it manually using mysql.
