DataTables add tag to column based on another attribute's value

I am trying to get the <span> tag into the "salesStatusName" column cell that already has some data in it. The tag should be placed in there when the value of the last column "completelyDelivered" is true. However, I also don't want "completelyDelivered" to even be a column in the table, so I assume I somehow need to access the value of "completelyDelivered" attribute in the received JSON.
How it looks now:

How I want it to look:
https://i.imgur.com/74nCnGu.png circle within Status Name column
I looked around and there are very similar questions, but I was unable to implement any solution.
DataTables instantiation code:
Note that I use AJAX and get JSON code returned
$(document).ready(function () {
$.fn.dataTable.moment('MM-DD-YYYY');
var datatableObj = $('#salesOrdersTable').DataTable({
"ajax": {
"url": "/Orders/GetAll",
"type": "GET",
error: function (error) {
RedirectUserToErrorPage();
}
},
"columns": [
{ "data": "salesOrderNumber" },
{ "data": "salesOrderNumber" },
{ "data": "poNumber" },
{ "data": "orderDateString" },
{ "data": "company" },
{ "data": "salesPerson" },
{ "data": "salesStatusName" },
{ "data": "completelyDelivered" }
],
"columnDefs": [
{
"targets": 0, //salesOrderNumber col
"orderable": false,
"render": function (data) {
return '<input type="button" value="+" onclick="location.href=\'/Shipments/Get?salesOrderNumber=' + data + '\'">';
}
},
{
"targets": 7, //completelyDelivered col
"render": function (data) {
if (String(data) == "true") {
return '<span class="SalesOrderDelivered">⬤</span>';
}
return "";
}
},
{ className: "salesOrderNumber", "targets": 1 },
],
});

I've done some research and figured it out.
Basically, if you write { "data": null }, as a definition for a column, you gain access to all properties of that row. So, in "render": function(data) function, write data["propertyName"] to get the value.
Code:
$(document).ready(function () {
$.fn.dataTable.moment('MM-DD-YYYY');
var datatableObj = $('#salesOrdersTable').DataTable({
"ajax": {
"url": "/Orders/GetAll",
"type": "GET",
error: function (error) {
RedirectUserToErrorPage();
}
},
{"data": "salesOrderNumber",},
{ "data": "salesOrderNumber" },
{ "data": "poNumber" },
{ "data": "orderDateString" },
{ "data": "company" },
{ "data": "salesPerson" },
{ "data": null, },//this is Sales Status column.
//"data: null" accesses all JSON data. We need this so that in "columnDefs" section
//we can use the values of both "completelyDelivered" and "salesStatusName" properties.
],
"columnDefs": [
{
"targets": 0, //button col
"orderable": false,
"render": function (data) {
return '<input type="button" value="+" onclick="location.href=\'/Shipments/GetShipments?salesOrderNumber=' + data + '\'">';
}
},
{
"targets": 6, //Sales Status col.
"render": function (data) { //This is where we can use values of "completelyDelivered" and "salesStatusName" JSON properties.
if (String(data["completelyDelivered"]) == "true") {
return (String(data["salesStatusName"]) + '<span class="AllDelivered"> ⬤</span>');
} else {
return String(data["salesStatusName"]);
}
}
},
{ className: "salesOrderNumber", "targets": 1 },
],
});

Datatable send current page number

I've been try to send current page number to server by overwrite a variable called pgno
here is my code :
function fill_datatable(status='',pgno='')
{
var pgno = 0;
table = $('.tb_scoin_available').DataTable({
"processing": true,
"serverSide": true,
"ordering" : false,
"infoCallback": function( settings, start, end, max, total, pre ) {
var api = this.api();
var pageInfo = api.page.info();
pgno = pageInfo.page+1;
return pgno;
},
"ajax":{
"url": base_url+'/adminPath/management_scoin/ajaxGetScoinAvailable',
"type": "POST",
"data":{ _token: csrf_token, status : status,pgno : pgno}
},
"columnDefs": [ { orderable: false} ],
"columns": [
{ "data": "no" },
{ "data": "created_at" },
{ "data": "serial_scoin" },
{ "data": "unit_scoin" },
{ "data": "unit_scoin_desc" },
{ "data": "unit_scoin_sc" },
{ "data": "unit_scoin_idr" },
],
});
}
when I try to alert on infoCallback :
alert(pgno) the variable already overwrited, but when I try to dump the request on backend the pgno POST give me null result like this :
Anyone can help me out ?

You can get the table page with the page() function, no need for the whole "page.info". It's better explained in Datatable's API: https://datatables.net/reference/api/page()
The method you're trying to access is only to get the information, not to set it. That is probably why it isn't working. Check their docs for better understanding of their API: https://datatables.net/reference/api/page.info()
EDIT:
You can get the current page through a simple calculation. Since you're using serverSide processing, you already have start and length. You just need to do start/length + 1 and you will get the current page number.

Send Data from Cassandra to DataTables (NoSQL)

Hey Guys I have a problem. I`m new to Cassandra and DataTables and my task is to send data from our 'Cassandra-Server' to the Table plug-in 'DataTables'.
I was looking for some examples or tutorials but I never found one for Cassandra-NoSQL.
I tried the following and this Error is always occurring:
PHP:
//setting header to json
header('Content-Type: application/json');
include 'connect.php';
$statement = new Cassandra\SimpleStatement("SELECT * FROM table1");
$result = $session->execute($statement);
//loop through the returned data
$data = array();
foreach ($result as $row) {
$data[] = $row;
}
//now print the data
print json_encode($data);
JS:
$(document).ready(function () {
'use strict';
var table = $('#main').DataTable({
"processing": true,
"serverSide": true,
"ajax": {
"url": "php/server-side.php",
"type": "GET"
},
"columns": [
{ "data": "name" },
{ "data": "type1" },
{ "data": "type2" },
{ "data": "type3" },
{ "data": "land" },
{
"data": "id",
"orderable": false
}
],
"order": [[0, 'asc']]
});
});
Error:
*Uncaught TypeError: Cannot read property 'length' of undefined
jquery.dataTables.min.js: 39*
I think DataTables don't know what to do with the information (json/$data).
In this example https://datatables.net/examples/data_sources/server_side.html
sspclass.php is used but it is written in SQL so no use for me =(
Can somebody help me with this specific problem?

Datatable row grouping

I have a working datatable that is retrieving data from a file :
I want to group row, something like this :
https://datatables.net/examples/advanced_init/row_grouping.html
My goal would to have my datatable to look like this, grouping row by the date (last column), but even looking at the code, I have trouble to make it work. I'd like some help to make that work if you could.
Here is the code of my datatable :
$(document).ready(function() {
$('#datatable').DataTable( {
"ajax": "<?php echo base_url()."assets/files/data/data.txt"; ?>" ,
"columns": [
{ "data": "etat" },
{ "data": "dest" },
{ "data": "message" },
{ "data": "exp" },
{ "data": "date" }
],
"order": [[ 0, "desc" ]],
"responsive": true
} );
} );

You should use drawCallback function.
Try.
$(document).ready(function() {
$('#datatable').DataTable({
"columns": [
{ "data": "etat" },
{ "data": "dest" },
{ "data": "message" },
{ "data": "exp" },
{ "data": "date" },
{ "data": "extra" }
],
"order": [[ 4, "desc" ]],
"responsive": true,
drawCallback: function (settings) {
var api = this.api();
var rows = api.rows({ page: 'current' }).nodes();
var last = null;
api.column(4, { page: 'current' }).data().each(function (group, i) {
if (last !== group) {
$(rows).eq(i).before(
'<tr class="group"><td colspan="8" style="BACKGROUND-COLOR:rgb(237, 208, 0);font-weight:700;color:#006232;">' + 'GRUPO ....' + group + '</td></tr>'
);
last = group;
}
});
}
});
} );
Result: https://jsfiddle.net/cmedina/7kfmyw6x/13/

It seems you get the error when outputting the url by PHP into the Javascript.
Try this instead:
ajax: "<?php echo base_url() . 'assets/files/data/data.txt'; ?>"
Not the single-qoutes in the PHP-code.

Post row datas from DataTable to an Ajax Form

I have a set of JSON data that are displayed using datatables. In one of the columns, I add a button and a text box only if the value in that column and another column meets a certain condition. this is the bit of code I used to do this:
$(document).ready(function (){
var alertTable = $('#alert-table').DataTable({
"jQueryUI": true,
"order": [ 3, 'desc' ],
"columns": [
{ "data": "source", "visible": false },
{ "data": "host" },
{ "data": "priority" },
{ "data": "ack", "render": function( data, type, row ) {
if (row.ack == "0" && row.priority > "2") {
return '<form><input class="ackname" type="text" value="Enter your name"><input class="ackbutton" type="button" value="Ack Alert" onclick="<get all items for that row and POST to a URL>"></form>';
}
return data;
}
},
],
"language": {
"emptyTable": "No Alerts Available in Table"
}
});
});
This works fine by adding a button and text in the cell. What I am looking to achieve is, when any of the button is been clicked, it should POST all the values for that row including what is typed in the text box to a URL which has another function that would extract those details and update the database and send back the refreshed data. I am new to datatables and jquery, any guide would be highly appreciated.

Have made some changes to the code, instead of form you can use div.
$(document).ready(function (){
var alertTable = $('#alert-table').DataTable({
"jQueryUI": true,
"order": [ 3, 'desc' ],
"columns": [
{ "data": "source", "visible": false },
{ "data": "host" },
{ "data": "priority" },
{ "data": "ack", "render": function( data, type, row ) {
if (row.ack == "0" && row.priority > "2") {
return '<div><input class="ackname" type="text" value="Enter your name"><input class="ackbutton" type="button" value="Ack Alert"></div>';
}
return data;
}
},
],
"language": {
"emptyTable": "No Alerts Available in Table"
}
});
$(document).on("click",".ackbutton",function() {
var currentIndex = $(this).parent().parent().index();
var rowData = alertTable.row( index ).data();
//extract the textbox value
var TextboxValue = $(this).siblings(".ackname").val();
var objToSave = {}; //Create the object as per the requirement
//Add the textbox value also to same object and send to server
objToSave["TextValue"] = TextboxValue;
$.ajax({
url: "url to another page"
data: JSON.stringify({dataForSave : objToSave}),
type: "POST",dataType: "json",
contentType: "application/json; charset=utf-8",
success: function(datas) {
//Your success Code
},
error: function(error) {
alert(error.responseText);
}
});
});
});
Since both the pages are in same project, you can also do it using single ajax, passing all the values to server at once and then calling the other page internally from server and passing in the values using query string.
This is not a running code, rather to give you a basic idea on how to proceed.
Hope this helps :)
