PHP: Reuse JQGrid response for Displaying data in DataTable - php

Question

First of all I am using JQGrid in my application. After changing my CSS to Bootstrap CSS.
I have to use DataTable. I want to reuse my controller pages which makes query to display the data in JQGrid.
Here is my controller page.
<?php
require_once("JsonHeader.php");
$at = $_SESSION['abc'];
$start_date = $_SESSION['start_date'];
$end_date = $_SESSION['end_date'];
if ($_SESSION['list'] == '-1') {
$user_query = "";
} else {
$user_list = $_SESSION['list'];
$user_query = " AND a.user_id IN ($list)";
}
$start_date = $_SESSION['start_date'];
$end_date = $_SESSION['end_date'];
if ($_SESSION['list'] == '-1') {
$user_query = "";
} else {
$user_list = $_SESSION['list'];
$user_query = " AND a.user_id IN ($list)";
}
$page = $_GET['page']; // get the requested page
$limit = $_GET['rows']; // get how many rows we want to have into the grid
$sidx = $_GET['sidx']; // get index row - i.e. user click to sort
$sord = $_GET['sord']; // get the direction
$qtype = ''; // Search column
$query = ''; // Search string
if (isset($_GET['searchField'])) {
$qtype = mysql_real_escape_string($_GET['searchField']);
}
if (isset($_GET['searchString'])) {
$query = mysql_real_escape_string($_GET['searchString']);
}
if (isset($_GET['searchOper'])) {
switch ($_GET['searchOper']) {
case 'eq':
$oper = '=';
$query = mysql_real_escape_string($_GET['searchString']);
break;
case 'ne':
$oper = '!=';
$query = mysql_real_escape_string($_GET['searchString']);
break;
case 'cn':
$oper = 'like';
$query = "%".mysql_real_escape_string($_GET['searchString'])."%";
break;
}
}
$searchSql1 = ($qtype != '' && $query != '') ? "and $qtype $oper '$query'" : '';
if (!$sidx)
$sidx = 1; // connect to the database
$result = mysql_query(sprintf("SELECT ae.col1,ae.col2,ae.col3, ae.col4,ae.col5,ae.col6,ae.col7,a.col8,a.col9,r.col10,p.col11
FROM $tablename3 ae,$tableName a, $tablename1 p, $tablename2 r
WHERE ae.col1=$at $searchSql1
AND a.col1 = $at
AND a.col5=r.col5
AND a.col6=p.col6
$user_query"));
$row = mysql_num_rows($result);
$count = $row;
if ($count > 0) {
$total_pages = ceil($count / $limit);
} else {
$total_pages = 0;
}
if ($page > $total_pages)
$page = $total_pages; $start = $limit * $page - $limit; // do not put
$limit * ($page - 1);
$SQL = sprintf("SELECT ae.col1,ae.col2,ae.col3, ae.col4,ae.col5,ae.col6,ae.col7,a.col8,a.col9,r.col10,p.col11
FROM $tablename3 ae,$tableName a, $tablename1 p, $tablename2 r
WHERE ae.col1=$at $searchSql1
AND a.col1 = $at
AND a.col5=r.col5
AND a.col6=p.col6
$query");
$result = mysql_query($SQL) or die("Couldn t execute query." . mysql_error());
$responce = new stdClass();
$responce->page = new stdClass();
$responce->total = new stdClass();
$responce->records = new stdClass();
$responce->page = $page;
$responce->total = $total_pages;
$responce->records = $count;
$i = 0;
while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) {
$responce->rows[$i]['id'] = $row['col1'];
$responce->rows[$i]['cell'] = array($row['col1'], $row['col2'], $row['col3'], $row['col4'], $row['col5'], $row['col6'], $time, $row['col7']);
$i++;
}
echo json_encode($responce);
?>
HOW can I change this for DataTable?.
Please provide me the best way...

Answer 1

Finally I found how to resue my controller page for DataTable. Simply change the post variables in the controller page.
Like
$_GET['page']; By $_REQUEST['sEcho']
$_GET['rows']; By $_REQUEST['iDisplayStart'],$_REQUEST['iDisplayLength']
$_GET['sord']; $_REQUEST['sSortDir_0']
$_GET['searchString']: $_GET['sSearch']:
And some changes the json response like
$ans['iTotalRecords'] = $count;
$ans['iTotalDisplayRecords'] = $count;
$ans['aaData'] = $aadata;
echo json_encode($ans);
