Step 3 : Create Controller


This is third step in which we want to make controller for handle http request of our web application. This will also handle ajax request also which has been send from view file.

app/Http/Controllers/PaginationController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use DB;

class PaginationController extends Controller
{
    function index()
    {
     $data = DB::table('posts')->paginate(5);
     return view('pagination', compact('data'));
    }

    function fetch_data(Request $request)
    {
     if($request->ajax())
     {
      $data = DB::table('posts')->paginate(5);
      return view('pagination_data', compact('data'))->render();
     }
    }
}
?>


Step 4 : Create View


Once you have make controller then for display controller data on web page we want to make on view file. Here for Ajax pagination here we have make two view file in file we will only dislay controller data and in seocnd view file we will include controller data file in second file and in second view file we have imported jQeury and Bootstrap library links.

resources/views/pagination.blade.php


<!DOCTYPE html>
<html>
 <head>
  <title>Laravel Pagination using Ajax</title>
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script>
  <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" />
  <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
  <style type="text/css">
   .box{
    width:600px;
    margin:0 auto;
   }
  </style>
 </head>
 <body>
  <br />
  <div class="container">
   <h3 align="center">Laravel Pagination using Ajax</h3><br />
   <div id="table_data">
    @include('pagination_data')
   </div>
  </div>
 </body>
</html>

<script>
$(document).ready(function(){

 $(document).on('click', '.pagination a', function(event){
  event.preventDefault(); 
  var page = $(this).attr('href').split('page=')[1];
  fetch_data(page);
 });

 function fetch_data(page)
 {
  $.ajax({
   url:"/pagination/fetch_data?page="+page,
   success:function(data)
   {
    $('#table_data').html(data);
   }
  });
 }
 
});
</script>


resources/views/pagination_data.blade.php

                                 <div class="table-responsive">
     <table class="table table-striped table-bordered">
      <tr>
       <th width="5%">ID</th>
       <th width="38%">Title</th>
       <th width="57%">Description</th>
      </tr>
      @foreach($data as $row)
      <tr>
       <td>{{ $row->id }}</td>
       <td>{{ $row->post_title }}</td>
       <td>{{ $row->post_description }}</td>
      </tr>
      @endforeach
     </table>

     {!! $data->links() !!}

    </div>


Step 5 : Set Route


This is last step in making Ajax Pagination in Laravel and lastly we want to set route for controller index() and fetch_data() method. Below you can find route code below.

routes/web.php

<?php

Route::get('/pagination', 'PaginationController@index');
Route::get('pagination/fetch_data', 'PaginationController@fetch_data');

?>

So here our code is ready, now we want to run this application we have to go to command prompt and write following command.


php artisan serve


Once this command successfully run then it will provide you base url of your Laravel Ajax pagination. For run pagination application in Laravel using Ajax you have to write following link in your web browser.
