class DatabaseSeeder extends Seeder
{

    public function run() {
        $faker = Faker::create();

    	foreach (range(1,10) as $index) {
            DB::table('employees')->insert([
                'name' => $faker->name,
                'email' => $faker->email,
                'phone_number' => $faker->phoneNumber,
                'dob' => $faker->date($format = 'D-m-y', $max = '2000',$min = '1990')
            ]);
        }
    }
}

Run command to generate the fake data.

php artisan db:seed

{
    public function showEmployees(){
      $employee = Employee::all();
      return view('index', compact('employee'));
    }
}

            <tbody>
                @foreach($employee ?? '' as $data)
                <tr>
                    <th scope="row">{{ $data->id }}</th>

                    <td>{{ $data->email }}</td>
                    <td>{{ $data->phone_number }}</td>
                    <td>{{ $data->dob }}</td>
                </tr>
                @endforeach
            </tbody>
        </table>

    </div>

    <script src="{{ asset('js/app.js') }}" type="text/js"></script>
</body>

</html>

Download PDF in Laravel

Now, we will learn how to export HTML to PDF and fetch users list from database and display in the PDF file format in Laravel.

Head over to app/Http/Controllers/EmployeeController.php and define the createPDF() function. This function will fetch all the records from the database, share users data with PDF blade template and, allow downloading the PDF file.

<?php

namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\Employee;
use PDF;

class EmployeeController extends Controller {

    // Display user data in view
    public function showEmployees(){
      $employee = Employee::all();
      return view('index', compact('employee'));
    }

    // Generate PDF
    public function createPDF() {
      // retreive all records from db
      $data = Employee::all();

      // share data to view
      view()->share('employee',$data);
      $pdf = PDF::loadView('pdf_view', $data);

      // download PDF file with download method
      return $pdf->download('pdf_file.pdf');
    }
}

Define Route

Open routes/web.php and insert the following code. It will create relation between the controller & the view over and above that it will also invoke the pdf download.

<?php

use Illuminate\Support\Facades\Route;
use App\Http\Controllers\EmployeeController;

/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/

Route::get('/', [EmployeeController::class, 'showEmployees']);

Route::get('/employee/pdf', [EmployeeController::class, 'createPDF']);

In the end, we have to add the following button above the table inside the index.blade.php. It will allow users to export HTML into PDF.

<a class="btn btn-primary" href="{{ URL::to('/employee/pdf') }}">Export to PDF</a>
