Laravel 9 PDF File Download using JQuery Ajax Request Example

Hi Guys,

In this example, I will learn you how to download a pdf file using jquery ajax in laravel 9. you can easily and simply download a pdf file using jquery ajax in laravel 9.

In this example, we will install barryvdh/laravel-dompdf composer package, and then after we will add a new route with a new controller file.

PDF is one of the basic requirement when you are working with erp level project or e-commerce website. we may need to create a pdf file for report or invoice etc. So, here I will give you a very simple example for create and download file in laravel 9.

Step 1: Download Laravel


Let us begin the tutorial by installing a new laravel application. if you have already created the project, then skip following step.

composer create-project laravel/laravel example-app

Step 2: Install dompdf package

We need dompdf package for html design to generate pdf So let's open terminal run bellow command to install dompdf package:

composer require barryvdh/laravel-dompdf

After successfully install package, open config/app.php file and add service provider and alias.

config/app.php

'providers' => [

....

Barryvdh\DomPDF\ServiceProvider::class,

],

'aliases' => [

....

'PDF' => Barryvdh\DomPDF\Facade::class,

]

Step 3: Add Route

In this step, We have to create two route for one route is preview pdf and second route to generate pdf and download pdf file. So let's open web.php file put bellow route:

routes/web.php

<?php

use App\Http\Controllers\PdfController;

/*

|--------------------------------------------------------------------------

| 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('pdf/preview', [PdfController::class, 'index']);

Route::get('pdf/generate', [PdfController::class, 'create']);

Step 4: Add Controller

Here you can create new controller as PdfController and add two method in this controller, first method is preview and last one is generate pdf and download pdf. So let's open terminal and put bellow command to create controller file.

php artisan make:controller PdfController

Now we can add two methods in PdfController file So let's open PdfController.php file put bellow code.we will store pdf file in public folder.

app/Http/Controllers/PdfController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use PDF;

class PdfController extends Controller

{

/**

* Write code on Method

*

* @return response()

*/

public function index()

{

return view('pdf.index');

}

/**

* Write code on Method

*

* @return response()

*/

public function create()

{

$pdf = PDF::loadView('pdf.pdf');

$path = public_path('pdf/');

$fileName = time().'.'. 'pdf' ;

$pdf->save($path . '/' . $fileName);

$pdf = public_path('pdf/'.$fileName);

return response()->download($pdf);

}

}

Step 5: Add Blade File

In last step. In this step we have to create preview blade file. So mainly we have to create preview file. So finally you have to create one preview blade file for preview pdf design:

resources/views/pdf/index.blade.php

},

success: function(response){

var link = document.createElement('a');

link.href = window.URL.createObjectURL(blob);

},
