Laravel Signature Pad Tutorial From Scratch

We will be using Laravel kenth-wood jquery UI signature pad library to implement digital signature pad in laravel application.

Step 1: Install Laravel New App

Step 2: Connect Database To App
Step 3: Create One Model and Migration
Step 4: Add Routes For digital Signature Pad

Step 5: Create Controller by Artisan Command
Step 6: Create Blade View
Step 7: Make Upload Directory

Step 8: Start Development Server

Step 1: Install Laravel New App

First of all we need to create a fresh laravel project, download and install Laravel using the below command

composer create-project --prefer-dist laravel/laravel blog

1	composer create-project --prefer-dist laravel/laravel blog

Step 2: Connect Database To App

Now, lets create a MySQL database and connect it with laravel application. After creating database we need to set database credential in application’s .env file.

 DB_CONNECTION=mysql 
 DB_HOST=127.0.0.1 
 DB_PORT=3306 
 DB_DATABASE=here your database name here
 DB_USERNAME=here database username here
 DB_PASSWORD=here database password here

DB_CONNECTION=mysql

DB_HOST=127.0.0.1

DB_PORT=3306

DB_DATABASE=here your database name here

DB_USERNAME=here database username here

DB_PASSWORD=here database password here

Step 3: Create Model and Migration

Now, in this step we will create model and migration file. Please run the following command:

php artisan make:model Signature -m

1	php artisan make:model Signature -m

Now, go to database/migrations directory and open create_signatures_table.php file in text editor. Then put the following code in your create_signatures_table.php file inside public directory.

<?php
 
use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
 
class CreateSignaturesTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('signatures', function (Blueprint $table) {
            $table->increments('id');
            $table->string('name');
            $table->string('signature');
            $table->timestamps();
        });
    }
 
    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('signatures');
    }
}

<?php

use Illuminate\Support\Facades\Schema;

use Illuminate\Database\Schema\Blueprint;

use Illuminate\Database\Migrations\Migration;

class CreateSignaturesTable extends Migration

{

/**

* Run the migrations.

* @return void

public function up()

{

Schema::create('signatures', function (Blueprint $table) {

$table->increments('id');

$table->string('name');

$table->string('signature');

$table->timestamps();

});

}

/**

* Reverse the migrations.

* @return void

public function down()

{

Schema::dropIfExists('signatures');

}

Now, run the migration to create database table using following artisan command:

php artisan migrate

1	php artisan migrate

Step 4: Add Routes For digital Signature Pad

After this, we need to define routes in “routes/web.php” file. Lets open “routes/web.php” file and add the following routes in it.

routes/web.php

Route::get('laravel-signature-pad','SignatureController@index');
Route::post('laravel-signature-pad','SignatureController@store');

1 2	Route::get('laravel-signature-pad','SignatureController@index'); Route::post('laravel-signature-pad','SignatureController@store');

Step 5: Create Controller by Artisan Command

Now, lets create a controller named SignatureController using command given below –

php artisan make:controller SignatureController

1	php artisan make:controller SignatureController

Then, Navigate to app/http/controllers directory and open SignatureController.php file. And put following code into SignatureController.php file:

<?php
 
namespace App\Http\Controllers;
 
use Illuminate\Http\Request;
use App\Signature;
 
class SignatureController extends Controller
{
    public function index()
    {
        return view('signature-pad');
    }
 
    public function store(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]);
 
        $signature = uniqid() . '.'.$image_type;
           
        $file = $folderPath . $signature;
 
        file_put_contents($file, $image_base64);
 
        $save = new Signature;
        $save->name = $request->name;
        $save->signature = $signature
        $save->save();
    
 
        return back()->with('success', 'Form successfully submitted with signature');
    }
}

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Signature;

class SignatureController extends Controller

{

public function index()

{

return view('signature-pad');

}

public function store(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]);

$signature = uniqid() . '.'.$image_type;

$file = $folderPath . $signature;

file_put_contents($file, $image_base64);

$save = new Signature;

$save->name = $request->name;

$save->signature = $signature

$save->save();

return back()->with('success', 'Form successfully submitted with signature');

}

Step 6: Create a blade view

Now, we will create one blade view file that name signature-pad.blade.php file for digital signature pad. Then put the following code into your signature-pad.blade.php file:

<!DOCTYPE html>

signaturePad.signature('clear');
$("#signature64").val('');
});
</script>
</body>
</html>

<h5>Laravel 7 Signature Pad Tutorial From Scratch</h5>

@if ($message = Session::get('success'))

<strong>{{ $message }}</strong>

var signaturePad = $('#signaturePad').signature({syncField: '#signature64', syncFormat: 'PNG'});

$('#clear').click(function(e) {

e.preventDefault();

signaturePad.signature('clear');

$("#signature64").val('');

});

</script>

</body>

</html>

Step 7: Make Upload Directory

In this step, navigate to your laravel project root directory and open public directory. Inside public directory, create one new directory name upload.

Step 8: Start Development Server

Now we are ready to run our example so lets start the development server using following artisan command –

php artisan serve
If you want to run the project diffrent port so use this below command 
php artisan serve --port=8080

php artisan serve

If you want to run the project diffrent port so use this below command

php artisan serve --port=8080

Now, open the following URL in browser to see the output –

http://127.0.0.1:8000/laravel-signature-pad
