Step 3: Create Routes

In this step, we will add routes to the web.php file.

routes/web.php

<?php
  
use Illuminate\Support\Facades\Route;
  
use App\Http\Controllers\PDFMergeController;
  
/*
|--------------------------------------------------------------------------
| 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-files', [PDFMergeController::class, 'index']);
Route::post('merge-pdf-files', [PDFMergeController::class, 'store'])->name('merge.pdf.files.post');

Step 4: Create PDFMergeController

Now, we will create a PDFMergeController.php file. So, add the following code to that file.

app/Http/Controllers/PDFMergeController.php

<?php
    
namespace App\Http\Controllers;
     
use Illuminate\Http\Request;
use Webklex\PDFMerger\Facades\PDFMergerFacade as PDFMerger;
  
class PDFMergeController extends Controller
{
     
    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        return view('merge-pdf');
    }
      
    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {   
        $this->validate($request, [
                'pdf_files' => 'required',
                'pdf_files.*' => 'mimes:pdf'
        ]);
      
         if($request->hasFile('pdf_files')){
            $pdf = PDFMerger::init();
      
            foreach ($request->file('pdf_files') as $key => $value) {
                $pdf->addPDF($value->getPathName(), 'all');
            }
       
            $fileName = time().'.pdf';
            $pdf->merge();
            $pdf->save(public_path($fileName));
  
        }
      
        return response()->download(public_path($fileName));
    }
     
}
