jquery datatable not pagiging except first page - datatable

Question

I have a datatable with server-sider processising.
Data come from table expected but it doesnt page by datatable. I see in debug total record count 14 of the database aaData whic gonna display is 5,
so I expect there will be 3 page.. but only 1 page diplayed and 5 rows in the page.
here is my tabl html:
<table style="text-align: center" class="table table-striped table-bordered table-hover" id="usersTable">
<thead>
<tr>
<th>
User Name
</th>
<th>
Account
</th>
<th>
Enable
</th>
<th>
Remark
</th>
</tr>
</thead>
<tbody>
</tbody>
</table>
and datatable def:
var tableObject = $("#usersTable").dataTable({
"bProcessing": true,
"bServerSide": true,
"sAjaxSource": "../../Controller/UserManagementControllercopy.php5",
"aoColumns": [
{ "mDataProp": "0", "sWidth": "40%", "bSearchable": false },
{ "mDataProp": "1", "sWidth": "20%"},
{ "mDataProp": "3", "sWidth": "20%" },
{ "mDataProp": "2", "sWidth":"20%" }
],
"fnServerData": function (sSource, aoData, fnCallback){
$.ajax({
"dataType": "json",
"contentType": "application/json; charset=utf-8",
"type": "GET",
"url": sSource,
"data": aoData,
"success": function(result){
fnCallback(result);
},
error: function (xhr, textStatus, error){
debugger
if (typeof console == "object") {
console.log(xhr.status + "," + xhr.responseText + "," + textStatus + "," + error);
}
}});
},
"oLanguage": {
"sLengthMenu": '<select>' +
'<option value="5">5</option>' +
'<option value="10">10</option>' +
'<option value="20">20</option>' +
'<option value="30">30</option>' +
'<option value="40">40</option>' +
'<option value="50">50</option>' +
'</select> Show'
},
"fnDrawCallback": function(){
},
"aaSorting": [
[1, 'asc']
],
"aLengthMenu": [
[5, 15, 20, -1],
[5, 15, 20, "All"] ],
"iDisplayLength": 5
});
and servercode:
$aColumns = array( 'USERNAME', 'ACCOUNT', 'REMARK', 'ENABLE');
$sQuery = " SELECT USERNAME,ACCOUNT,REMARK,ENABLE FROM users LIMIT ".$_GET['iDisplayStart'].", ".$_GET['iDisplayLength'].";";
$dbObject = Connection::getConnection();
$request = $dbObject->dbh->prepare($sQuery);
if ($request->execute())
{
$resultData["Data"] = $request->fetchAll(PDO::FETCH_ASSOC);
$sQuery = "SELECT COUNT(USERNAME) FROM users";
$request = $dbObject->dbh->prepare($sQuery);
$request->execute();
$iTotal = $request->fetchColumn(0);
$output = array(
"sEcho" => intval($_GET['sEcho']),
"iTotalRecords" => intval($iTotal),
"iTotalDisplayRecords" => intval($_GET['iDisplayLength']),
"aaData" => array()
);
for ( $j=0 ; $j<count($resultData["Data"]) ; $j++ )
{
$aRow = $resultData["Data"][$j];
$row = array();
$output["Success"]=true;
echo json_encode($output);
}
and here how returned data from get request of datatable seem is:
(chrome developer console)

Answer 1

you are returning the wrong value for iTotalDisplayRecords in the json array. It should be the Total records, after filtering (i.e. the total number of records after filtering has been applied - not just the number of records being returned in this result set)
see the documentation and refer this
