In this tutorial, I will explain how to engender signature pad in laravel 8.You can easily use jquery ui signature pad and save image using laravel. i would like to give you full example of larevel signature pad and save image to database. we will use jquery signature pad & canvas image.

So,you can use this tutorial code and you can implement your laravel project.

We will use keith-wood jquery ui signature pad for you can create your signature on it. we will take laravel form and submit that signature image and store that image into folder. you just have to just create bellow two files and you can get example.

Here,i will show you full example of signature pad in laravel so follow my bellow steps.

Step: 1 Add Route

In this first step, we are doing from scratch so we will add two routes, one for signature pad and another for signature upload. So you have to simply add two new routes in your laravel application.

Path : /routes/web.php
<?php

use Illuminate\Support\Facades\Route;
use App\Http\Controllers\SignController;


/*
|--------------------------------------------------------------------------
| 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!
|
*/

// SignController
Route::get('sign-pad',[SignController::class ,'index']);
Route::post('sign-pad',[SignController::class ,'upload'])->name('sign.pad');

Step: 2 Create SignController

In second step, we will create new SignController file to handle request of created two new route. In this Controller we define two method, index() and upload(). Both method will handle route request. So let's create new controller and put code.

Path : /app/Http/Controllers/SignController.php
<?php

namespace App\Http\Controllers;
use Illuminate\Http\Request;

class SignController extends Controller
{
    /**
     * Write Your Code..
     *
     * @return string
    */
    public function index()
    {
        return view('signaturePad');
    }

    /**
     * Write Your Code..
     *
     * @return string
    */
    public function upload(Request $request)
    {
        $folderPath = public_path('upload/');

        $image_parts = explode(";base64,", $request->signed);

        $image_type_aux = explode("image/", $image_parts[0]);

        $image_type = $image_type_aux[1];

        $image_base64 = base64_decode($image_parts[1]);

        $file = $folderPath . time() . '.'.$image_type;

        file_put_contents($file, $image_base64);
        return back()->with('success', 'success Full upload signature');
    }
}

Step 3: Create Blade File

In last step we will create signaturePad.blade.php file and write code of signature pad code.

Path : resources/views/signaturePad.blade.php

                            <div id="sig"></div>
                            <br/>

                            <textarea id="signature64" name="signed" style="display: none"></textarea>
                        </div>
                        <br/>
                        <button class="btn btn-success btn-block">Save</button>
                    </form>
               </div>
           </div>
       </div>
   </div>
</div>
<script type="text/javascript">
    var sig = $('#sig').signature({syncField: '#signature64', syncFormat: 'PNG'});
    $('#clear').click(function(e) {
        e.preventDefault();
        sig.signature('clear');
        $("#signature64").val('');
    });
</script>
</body>
</html>

After Create one "upload" name folder in the public folder.

Now we are ready to run our example so run bellow command for quick run:
