If you need to create one pdf file from multiple pdf files then you can follow this tutorial. If you want to create pdf file then you can follow this tutorial: Generate PDF file in Laravel.

In this tutorial, we will use lara-pdf-merger composer package and create one example. we will also create two routes GET and POST. then we will create one controller file with one blade file. When user will select multiple pdf files then it will return single file with merge.

So, let's follow few steps and get easy example.

Step 1: Install Laravel

This is optional; however, if you have not created the laravel app, then you may go ahead and execute the below command:

composer create-project laravel/laravel example-app

Step 2: Install webklex/laravel-pdfmerger Package

first of all we will install webklex/laravel-pdfmerger composer package by following composer command in your laravel application.

composer require webklex/laravel-pdfmerger

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

config/app.php

'providers' => [

....

Webklex\PDFMerger\Providers\PDFMergerServiceProvider::class

],

'aliases' => [

....

'PDFMerger' => Webklex\PDFMerger\Facades\PDFMergerFacade::class,

]

Step 3: Create Routes

In this is step we need to create routes for display form. so open your "routes/web.php" file and add following route.

routes/web.php

<?php

use Illuminate\Support\Facades\Route;

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('merge-pdf', [PDFController::class, 'index']);

Route::post('merge-pdf', [PDFController::class, 'store'])->name('merge.pdf.post');

Step 4: Create Controller

Here,we require to create new controller PDFController that will manage get and post method of route. So let's put bellow code.

app/Http/Controllers/PDFController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use Webklex\PDFMerger\Facades\PDFMergerFacade as PDFMerger;

class PDFController extends Controller

{

/**

* Show the application dashboard.

*

* @return \Illuminate\Http\Response

*/

public function index()

{

return view('mergePDF');

}

/**

* Show the application dashboard.

*

* @return \Illuminate\Http\Response

*/

public function store(Request $request)

{

$this->validate($request, [

'filenames' => 'required',

'filenames.*' => 'mimes:pdf'

]);

if($request->hasFile('filenames')){

$pdf = PDFMerger::init();

foreach ($request->file('filenames') as $key => $value) {

$pdf->addPDF($value->getPathName(), 'all');

}

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

$pdf->merge();

$pdf->save(public_path($fileName));

}

return response()->download(public_path($fileName));

}

}

Step 5: Create Blade File

In Last step, let's create mergePDF.blade.php(resources/views/mergePDF.blade.php) for layout of pdf file and put following code:

resources/views/mergePDF.blade.php

<html lang="en">

<head>
