php - Jquery DataTable serverside rendering and pagination error in front end -


i using php , query select * table , result want show in jquery datatable in server side processing means want use jquery datatable's own ajax method. have total 58 rows. default should have 6 page. 10 rows per page. data coming , shown in table. wrong pagination.

actually shows 58 rows in first page , showing 6 pagination buttons. if click on nothing working. searching , sorting not working.

i not pasting sql code here pasting procedural code of php here.

php code:

require_once("logic/logsdatalogic.php");  $ldl = new logsdatalogic(); $data = $ldl->getdatabyfromdatetodate();  $arr = [     "draw" => $_post["draw"],     "recordstotal" => count($data),     "recordsfiltered" => count($data),     "data" => $data ];  echo json_encode($arr);

jquery code:

$(document).ready(function(){                            $('#logs_table').datatable( {                 "processing": true,                 "serverside": true,                 ajax: {                     url: '../app/getdata.php',                     type: "post"                 }             } );     });

i have attached image of final result.table image here

sol 1:

if dont want pagination server set "serverside": false, bring record ie 58 @ 1 go pagination work.

sol 2:

if want pagination server side means fetch 10 record each time follow these steps

you have added "serverside": true, when console along other parameters some additional parameters passed. need handle in server side query limit 20,10

refer: https://datatables.net/examples/server_side/simple.html

eg: 

draw:4 columns[0][data]:0 start:20 length:10 search[value]: search[regex]:false

explanation:

when set serverside false

datatable gets records server(in case 58) , paginate in ui suggested(10 rec each page) when chnage page no ajax call fired

when set serverside true

datable gets first 10 record , when change page ajax call fired set of 10 records. datatable adds parameters along request , expect handle in server side eg: first record , total no of record per set , total no of record available

so each request start , length passed no of records index

in response datable expect "draw":2,"recordstotal":57,"recordsfiltered":57 along data

draw unique key can use request recordstotal no no of record : need additiona query count of records
