In many applications, you have been observed file upload process is bit attractive. Inside this article we will see the concept of Laravel 8 drag and drop file upload using dropzone jquery plugin.

Dropzone.js is a jquery plugin, dropzone.js through we can select one by one image and also with preview.

Uploading files in application using dropzone plugin is super easy. This tutorial is very interesting and easy to learn.

We can upload any type of file using dropzone but for this tutorial we will use the feature to upload only images via dropzone jquery plugin.

Let’s get started.


Laravel Installation

We will create laravel project using composer. So, please make sure your system should have composer installed. If not, may be this article will help you to Install composer in system.

Here is the command to create a laravel project-

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

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 Database & Connect

To create a database, either we can create via Manual tool of PhpMyadmin or by means of a mysql command.

CREATE DATABASE laravel_app;

To connect database with application, Open .env file from application root. Search for DB_ and update your details.

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=laravel_app
DB_USERNAME=root
DB_PASSWORD=root

Create Model & Migration

We will create a model and a migration file. These are because when we upload images from dropzone we will save it to database.

Open terminal and run this artisan command

$ php artisan make:model ImageUpload -m

It will create a model (ImageUpload.php) and a migration file (2021_04_30_152115_create_image_uploads_table.php). -m to create migration file.

You should see these two files.

  • Model file is at /app/Models
  • Migration file is at /database/migrations

Open Migration file and write this updated code into it.

<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

class CreateImageUploadsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('image_uploads', function (Blueprint $table) {
            $table->id();
            $table->text('filename');
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('image_uploads');
    }
}

Migrate Migration

Back to terminal and run this artisan command.

$ php artisan migrate

It will create a table image_uploads into database.


Create Controller

Next, we need to create a controller file.

$ php artisan make:controller DropzoneController

It will create a file DropzoneController.php at /app/Http/Controllers folder.

Open DropzoneController.php and write this updated code.

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Models\ImageUpload;

class DropzoneController extends Controller
{
    /**
     * Generate Image upload View
     *
     * @return void
     */
    public function dropzone()
    {
        return view('upload-view');
    }

    /**
     * Image Upload Code
     *
     * @return void
     */
    public function dropzoneStore(Request $request)
    {
        $image = $request->file('file');

        $imageName = $image->getClientOriginalName();

        $image->move(public_path('images'), $imageName);

        $imageUpload = new ImageUpload();
        $imageUpload->filename = $imageName;
        $imageUpload->save();

        return response()->json([
            'status' => 1,
            'filename' => $imageName
        ]);
    }
}

Create Routes

Open web.php from /routes folder.

# Add this header
use App\Http\Controllers\DropzoneController;

//...
Route::get('image-upload', [ DropzoneController::class, 'dropzone' ]);
Route::post('dropzone/store', [ DropzoneController::class, 'dropzoneStore' ])->name('dropzone.store');

Create Blade Layout File

Next, need to create upload-view.blade.php inside /resources/views folder.

Open this view file and write this updated code.

        </div>
    </div>
    <script type="text/javascript">
        Dropzone.options.imageUpload = {
            maxFilesize: 1,
            acceptedFiles: ".jpeg,.jpg,.png,.gif",
        };
    </script>
</body>

</html>

Application Testing

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

$ php artisan serve

URL: http://127.0.0.1:8000/image-upload
