php - PHP jqgridで合計、レコード、ページを指定する方法

Question

Web サービスに接続する getdocuments メソッドを使用するこの php コードがあります。 limit 、 pageNumber 、およびオプションのフィルター配列を渡すと、レコードの総数とページ番号に加えてデータの配列が返されます

結果をjqgridに表示したいのですが、たとえば20個のレコードを持ってきて、ユーザーが次のページに行くと次の20個のレコードを持ってきます。

<?php

//ini_set("display_errors","1");
require_once 'grid/jq-config.php';
// include the jqGrid Class
require_once "grid/jqGrid.php";
// include the driver class
require_once "grid/jqGridArray.php";

// include the calendar
require_once "grid/jqCalendar.php"; 

// include the document class 
require_once "lib/document.php";
// include heler.php which contain some helper functions
require_once "lib/helper.php";
// create the array connection
$conn = new jqGridArray();
// Create the jqGrid instance
$grid = new jqGridRender($conn);
// prepare array that contains fileds name which user can filter on 
$fields = array("BatchNumber", "SenderCode","ReceiverCode","DocumentNumber","DocumentType","InResponse","SubmitDate");


if(get_magic_quotes_gpc()){
  $d = stripslashes($_REQUEST["filters"]);
}else{
  $d = $_REQUEST["filters"];
}
$d = json_decode($d);

for($i = 0; $i < count($d->rules); $i++){
    foreach ($fields as $value) {
        if($d->rules[$i]->field == $value){
            $option[$value] == $d->rules[$i]->data;
        }
    }
}


if(isset($_GET["page"])){
 $option["PageNumber"] = $_GET["page"];
}

    $option["PageNumber"] = 1;

    $option["Limit"]  = $_GET["rows"];

$grid->dataType = 'json';
$grid->setPrimaryKeyId('BatchNumber');

$grid->setColModel();

$grid->setUrl('grid_documents.php');



$grid->setGridOptions(array(

// Enable search

// Activate single search

// Enjoy

$grid->renderGrid('#grid','#pager',true, null, null, true,true);

firebug {"records":20,"page":1,"total":1} で http リクエストを調べたところ、グリッドは 1 ページで 20 レコードしか表示しませんでした。20 件のレコードを表示し、ページネーションを有効にして、[次へ] を押して次の 20 件のレコードを表示できるようにしたいと考えています。これらの値を {"total":"56","page":"1","re​​cords":"560" のようにしたい
