Hi Guys,

This example is focused on merge multiple pdf files laravel. step by step explain laravel 9 merge pdf files. you will learn dompdf merge pdf laravel. i would like to show you laravel merge pdf files.

As we know almost document written on pdf. so it you need to send email or fax then you might be require to merge one pdf file instead of multiple pdf files. If you need to create one pdf file from multiple pdf files then you can follow this tutorial.

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: 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 lara-pdf-merger Package

first of all we will install lara-pdf-merger composer package by following composer command in your laravel 9 application.

composer require lynx39/lara-pdf-merger

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

config/app.php 
'providers' => [
    LynX39\LaraPdfMerger\PdfMergerServiceProvider::class,
],

'aliases' => [
    'PdfMerger' => LynX39\LaraPdfMerger\Facades\PdfMerger::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\FileController;

/*
|--------------------------------------------------------------------------
| 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('file',[FileController::class,'create']);
Route::post('file',[FileController::class,'store']);
Step 4: Create Controller

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

php artisan make:controller FileController
app/Http/Controllers/FileController.php 
<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class FileController extends Controller
{
    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Http\Response
     */
    public function create()
    {
        return view('create');
    }

    /**
     * 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 = new \LynX39\LaraPdfMerger\PdfManage;

            foreach ($request->file('filenames') as $key => $value) {
                $pdf->addPDF($value->getPathName(), 'all');
            }
            
            $input['file_name'] = time().'.pdf';
            $pdf->merge('file', public_path($input['file_name']), 'P');
        }

        return response()->download(public_path($input['file_name']));
    }
}
Step 5: Create Blade File

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

resources/views/create.blade.php 
<html lang="en">
<head>
    <title>How To Merge Two PDF Files in Laravel 9 - MyWebtuts.com</title>
    <script src="jquery/1.9.1/jquery.js"></script>
    <link rel="stylesheet" href="3.3.6/css/bootstrap.min.css">
</head>
<body>
    <div class="container">
        @if (count($errors) > 0)
            <div class="alert alert-danger">
                <strong>Sorry!</strong> There were more problems with your HTML input.<br><br>
                <ul>
                    @foreach ($errors->all() as $error)
                        <li>{{ $error }}</li>
                    @endforeach
                </ul>
            </div>
        @endif
        <h3 class="well">Laravel 9 How To Merge Two PDF Files Example - MyWebtuts.com</h3>
        <form method="post" action="{{url('file')}}" enctype="multipart/form-data">
            {{csrf_field()}}
            <input type="file" name="filenames[]" class="myfrm form-control" multiple="">
            <button type="submit" class="btn btn-success" style="margin-top:10px">Submit</button>
        </form>        
    </div>
</body>
</html>

Now we are ready to run this example and check it...

So, basically you can use this way: 
$pdf = new \LynX39\LaraPdfMerger\PdfManage;

$pdf->addPDF(public_path('/upload/1547633948.pdf'), 'all');
$pdf->addPDF(public_path('/upload/test.pdf'), 'all');

$pdf->merge('file', public_path('/upload/created.pdf'), 'P');
dd('done');
