Datatables, There is no problem when writing the initial function, but when it is added more and more, if you suddenly select all, not work
Hi there,
i have a table with over 8.000 entries (until now, data will rise in future). In some cases i have to export all of them to Excel, therefor i set the lengthMenu to:
Plain text
"lengthMenu": [[10, 25, 50, 250, -1], [10, 25, 50, 250, "All"]],
It works fine until i use the "All" statement. With "All" i get the following error:
Unable to get property 'length' of undefined or null reference
Can anybody help me? Normally it makes no sense to show all 8.000 entries on the webpage, but i have to export them all to Excel. Perhaps someone knows a better way.
이것은 ajaxfile.php
<?php
include 'config.php';
$request = $_POST['request'];
// Datatable data
if($request == 1){
## Read value
$draw = $_POST['draw'];
$row = $_POST['start'];
$rowperpage = $_POST['length']; // Rows display per page
$columnIndex = $_POST['order'][0]['column']; // Column index
$columnName = $_POST['columns'][$columnIndex]['data']; // Column name
$columnSortOrder = $_POST['order'][0]['dir']; // asc or desc
$searchValue = mysqli_real_escape_string($con,$_POST['search']['value']); // Search value
## Search
$searchQuery = " ";
if($searchValue != ''){
$searchQuery .= " and (emp_name like '%".$searchValue."%' or
email like '%".$searchValue."%' or
city like'%".$searchValue."%' ) ";
}
## Total number of records without filtering
$sel = mysqli_query($con,"select count(*) as allcount from employee");
$records = mysqli_fetch_assoc($sel);
$totalRecords = $records['allcount'];
## Total number of records with filtering
$sel = mysqli_query($con,"select count(*) as allcount from employee WHERE 1 ".$searchQuery);
$records = mysqli_fetch_assoc($sel);
$totalRecordwithFilter = $records['allcount'];
## Fetch records
$empQuery = "select * from employee WHERE 1 ".$searchQuery." order by ".$columnName." ".$columnSortOrder." limit ".$row.",".$rowperpage;
$empRecords = mysqli_query($con, $empQuery);
$data = array();
while ($row = mysqli_fetch_assoc($empRecords)) {
$data[] = array(
"action"=>"<input type='checkbox' class='delete_check' id='delcheck_".$row['id']."' onclick='checkcheckbox();' value='".$row['id']."'>",
"emp_name"=>$row['emp_name'],
"email"=>$row['email'],
"gender"=>$row['gender'],
"salary"=>$row['salary'],
"city"=>$row['city'],
);
}
## Response
$response = array(
"draw" => intval($draw),
"iTotalRecords" => $totalRecords,
"iTotalDisplayRecords" => $totalRecordwithFilter,
"aaData" => $data,
);
echo json_encode($response);
exit;
}
// Delete record
if($request == 2){
$deleteids_arr = $_POST['deleteids_arr'];
foreach($deleteids_arr as $deleteid){
mysqli_query($con,"DELETE FROM employee WHERE id=".$deleteid);
}
echo 1;
exit;
}
?>

Datatables search input doesn't work in OctoberCMS

I'm working with Datatables server-side processing in OctoberCMS.
Everything works fine but search input doesn't work.
Search input works fine as I tried it in client-side processing.
Datatables part Javascript
$(document).ready(function() {
var tableId = "datalist";
var table = $('#' + tableId).DataTable({
processing: true,
serverSide: true,
ajax: {
url: '/ajax?tb={{ tableName|raw() }}&fd={{ fields|raw() }}',
type: 'GET',
//tb: 'BYAPPS_apps_data',
error: function(e) {
console.log(e);
}
},
paging: true,
pageLength: 50,
"info": false,
"autoWidth": true,
"fixedHeader": false,
"responsive": true,
"orderClasses": false,
"stateSave": true,
"dom": 'Bfrtip',
"buttons": [
'excel', 'copy'
],
});
$('.dataTables_filter input').bind('keyup', function () {
console.log('here');
table.search(this.value).draw();
});
});
Ajax part PHP file
function onStart()
{
$table = $_GET['tb'];
$length = $_GET['length'];
$start = $_GET['start'];
$fields = explode("|", $_GET['fd']);
$result = DB::table($table)->skip($start)->limit($length)->get();
$data = array();
foreach($result as $row) {
$sub_array = array();
for ($i = 0; $i < count($fields); $i++) {
$sub_array[] = $row->{$fields[$i]};
}
$data[] = $sub_array;
}
$output = array(
"draw" => intval($_GET['draw']),
"recordsTotal" => DB::table($table)->count(),
"recordsFiltered" => DB::table($table)->count(),
"data" => $data,
);
echo json_encode($output);
}
How can I fix this and make the search input work?

json works on localhost but not on server

I have the below part of code which works on my local machine but not on the server.
When I execute it on the server then am getting an error as "Uncaught SyntaxError: Unexpected token ;"
<?php
$checkValue = array();
$i= 0;
while ($row = mysql_fetch_array($searchdetails)) {
$checkValue[$i][] = $row['ID'];
$checkValue[$i][] = $row['1'];
$checkValue[$i][] = $row['2'];
$checkValue[$i][] = $row['3'];
if(#$row['4'] == "NULL" || #$row['4'] == NULL) {
$checkValue[$i][] = "NULL";
}else{
$sql = "SELECT * FROM Class WHERE ID_Class =".#$row['4'];
$data = mysql_query( $sql );
$class = mysql_fetch_assoc($data);
$checkValue[$i][] = $class['Class'];
}
if(#$row['5'] == "NULL" || #$row['5'] == NULL) {
$checkValue[$i][] = "NULL";
}else{
$sql = "SELECT * FROM Place WHERE ID_Place =".#$row['5'];
$data = mysql_query( $sql );
while($row1 = mysql_fetch_array($data)) {
$checkValue[$i][] = $row1['1'];
}
}
$i++;
}
?>
<script>
var grid;
var columns = [
{ id: "switch", name: "switch", field: "switch", formatter: imageFormatter, sortable: true },
{ id: "college", name: "college", field: "college", width: 50 },
{ id: "Number", name: "Number", field: "Number", width: 50 },
{ id: "Class", name: "Class", field: "Class",sortable: true },
{ id: "Place", name: "Place", field: "Place", width: 40 },
];
$(function () {
var MS_PER_DAY = 24 * 60 * 60 * 1000;
var data = [];
**var listdata = <?php echo json_encode($checkValue);?>;**
console.log(listdata);
for (var i = 0; i < listdata.length; i++) {
data[i] = {
switch: listdata[i][0],
college: listdata[i]['1'],
Number: listdata[i]['2'],
Strength: listdata[i]['3'],
Place: listdata[i]['4'],
};
}
})
</script>
I tried this after searching for different answers in Stackoverflow
var listdata = <?php echo json_encode($checkValue)?>;
but still it doesn't work.
What might be the issue thats stopping it here. Any help on this is much more appreciated!!
EDIT: I identified the reason, The table class has some Spanish characters in it and so it is not displaying the data. How to overcome with these characters?

How to do data tables in codeigniter?

I am fetching records from database and converting data into json array. I am getting json response correctly. but table shows no entry in my view.. please see once . Thanks.
my controller
function test() {
$list = $this->get_data_model->get_apartment_details();
$data = array();
$no = $_POST['start'];
foreach ($list as $apartments) {
$no++;
$row = array();
$row[] = $no;
$row[] = $apartments->a_id;
$row[] = $apartments->a_name;
$data[] = $row;
}
$output = array(
"draw" => 5,
"recordsTotal" => 2,
"recordsFiltered" => 1,
"data" => $data
);
echo json_encode($output);//
}
my view
<section class="tab-pane fade in active" id="newPanel">
<table style='width:100%'' class='table' id='example'>
<thead>
<tr>
<th> ID </th>
<th> Name </th>
<th> Activate </th>
<th> Edit </th>
</tr>
</thead>
</table>
</section>
my ajax call
$('#example').DataTable( {
"processing" : true,
"serverSide" : true,
"ajax" : {
"type" : "POST",
"url": "<?php echo base_url("apartments/test");?>",
"dataSrc" : ""
},
"columns": [
{ "data": "a_id"},
{ "data": "a_name" }
],
"dom": 'Bfrtip',
"buttons": [
{
"extend": 'copyHtml5',
"exportOptions": {
"columns": ':contains("Office")'
}
},
'excelHtml5',
'csvHtml5',
'pdfHtml5'
]
} );
} );

Your Table ID attribute and your ajax call id attribute is different. hope below code will help you.
$('#newPanel').DataTable( {
"processing" : true,
"serverSide" : true,
"ajax" : {
"type" : "POST",
"url": "<?php echo base_url("apartments/test");?>",
"dataSrc" : ""
},
"columns": [
{ "data": "a_id"},
{ "data": "a_name" }
],
"dom": 'Bfrtip',
"buttons": [
{
"extend": 'copyHtml5',
"exportOptions": {
"columns": ':contains("Office")'
}
},
'excelHtml5',
'csvHtml5',
'pdfHtml5'
]
} );
} );

Data Tables Jquery Dynamic Fill

I am using DataTables in one of my projects in which I have to fill it with the Oracle query results. I am referring to this document.
Problem:
All the 10 columns returned by query get displayed in row 1 column 1 of the table.
Javascript
$('#inquiryForm').submit(function(){
var cnic = "data="+ $( "#cnicInd" ).val();
//alert(cnic);
$.ajax({
type: "POST",
url: "php/inquiryInd.php",
data: cnic,
success: function(datapage) {
//$("#errmsg").html(data).show();
var datacopy = [[datapage]];
prompt("Result",datacopy);
$('#dataTables-example').DataTable({
responsive: true,
"data": datacopy,
columns: [
{ title: "Policy No." },
{ title: "Client Name" },
{ title: "Gross Premium" },
{ title: "Next Due Date" },
{ title: "Commencement Date" },
{ title: "Cash Value" },
{ title: "Total Amount Paid" },
{ title: "Total Amount Due" },
{ title: "Total unconsumed Amount" },
{ title: "Status" }
]
});
}
});
$('#searchTable').show();
return false;
});
inquiryInd.php
while (($row = oci_fetch_array($stmnt)) != false) {
$result = "";
$result .= '"'.$row['PROPOSAL']."\"";
$result .= ',"'.$row['FULLNAME']."\"";
$result .= ',"'.$row['GROSSPREMIUM']."\"";
$result .= ',"'.$row['NEXTDUEDAT']."\"";
$result .= ',"'.$row['COMMENDATE']."\"";
$result .= ',"'.$row['CASH_VALUE']."\"";
$result .= ',"'.$row['TOTAL_AMOUNT_PAID']."\"";
$result .= ',"'.$row['TOTAL_AMOUNT_DUE']."\"";
$result .= ',"'.$row['TOTAL_AMOUNT_DUE']."\"";
$result .= ',"'.$row['STATUS']."\"";
//$result .= ']';
$dataset .= $result;
//Something like "Tiger Nixon", "System Architect", "Edinburgh", "5421", "2011/04/25", "$320,800"
}
Please let me know what am I doing wrong. Any help will be highly appreciated.
