Let’s get started.

Laravel Installation

Open terminal and run this command to create a laravel project.

$ composer create-project laravel/laravel myblog

It will create a project folder with name myblog inside your local system.

To start the development server of laravel –

$ php artisan serve

URL: http://127.0.0.1:8000

Assuming laravel already installed inside your system.

Create Images Folder

Go to /public folder available at application root. Create a folder with name images. We will save generated signature images inside it.

Make sure images folder should have sufficient permission to write content into it.

Create Controller

Open project into terminal and run this command into it.

$ php artisan make:controller DataController

It will create DataController.php file inside /app/Http/Controllers folder. Open controller file and write this code into it.

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class DataController extends Controller
{
    public function index()
    {
        return view('signature');
    }
      
    public function store(Request $request)
    {
        $folderPath = public_path('images/');
        
        $image = explode(";base64,", $request->signed);
              
        $image_type = explode("image/", $image[0]);
           
        $image_type_png = $image_type[1];
           
        $image_base64 = base64_decode($image[1]);
           
        $file = $folderPath . uniqid() . '.'.$image_type_png;
      
        file_put_contents($file, $image_base64);
      
        return back()->with('success', 'Signature saved successfully !!');
    }
}

Create Template

Create a fie signature.blade.php inside /resources/views folder.

Open signature.blade.php and write this code into it.

    var sig = $('#sig').signature({syncField: '#signature', syncFormat: 'PNG'});
    $('#clear').click(function(e) {
        e.preventDefault();
        sig.signature('clear');
        $("#signature").val('');
    });
</script>
</body>

Add Route

Open web.php file from /routes folder. Add these routes into it.

//...

use App\Http\Controllers\DataController;

//...

Route::get('signature-pad', [DataController::class, 'index']);
Route::post('signature-pad', [DataController::class, 'store'])->name('signature_pad.store');

Application Testing

Open project to terminal and type the command to start development server

$ php artisan serve

URL – http://127.0.0.1:8000/signature-pad

When we hit Save button, it will save the signature image into images folder.
