Laravel 5.8 Dropzone Multiple Image Upload with Remove Link

In this tutorial you will learn about the Laravel 5.8 Dropzone Multiple Image Upload with Remove Link and its application with practical example.

In this Laravel 5.8 Dropzone Multiple Image Upload with Remove Link example, I will show you how to upload files with drag and drop interface using dropzone.js in your Laravel 5 applications. Dropzone is an open source light weight JavaScript library that provides drag and drop features to upload images with preview images. In this example before uploading the image we will display preview of the image along with a remove image link and then save it into directory. In order to use dropzone plugin we need to include the Dropzone javascript and CSS files in your laravel blade file. This tutorial we learn to :-

Install Laravel 5.8

First of all we need to create a fresh laravel project, download and install Laravel 5.8 using the below command

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

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

Configure Database In .env file

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.

.env

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

DB_CONNECTION=mysql

DB_HOST=127.0.0.1

DB_PORT=3306

DB_DATABASE=DropzoneImageUpload

DB_USERNAME=root

DB_PASSWORD=

Generate Migration

Now, we have to define table schema for photos table. Open terminal and let’s run the following command to generate a migration file to create photos table in our database.

php artisan make:migration create_photos_table

1	php artisan make:migration create_photos_table

Once this command is executed you will find a migration file created under “database/migrations”. lets open migration file and put following code in it –

<?php

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

class CreatePhotosTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('photos', function (Blueprint $table) {
            $table->bigIncrements('id');
            $table->string('photo_name');
            $table->timestamps();
        });
    }

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

<?php

use Illuminate\Support\Facades\Schema;

use Illuminate\Database\Schema\Blueprint;

use Illuminate\Database\Migrations\Migration;

class CreatePhotosTable extends Migration

{

/**

* Run the migrations.

* @return void

public function up()

{

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

$table->bigIncrements('id');

$table->string('photo_name');

$table->timestamps();

});

}

/**

* Reverse the migrations.

* @return void

public function down()

{

Schema::dropIfExists('photos');

}

Run Migration

Now, run following command to migrate database schema.

php artisan migrate

1	php artisan migrate

After, the migration executed successfully the photos table will be created in database along with migrations, password_resets and users table.

Create Model

Next, we need to create a model called Photo using below command.

php artisan make:model Photo

1	php artisan make:model Photo

Once, the above command is executed it will create a model file Photo.php in app directory.

Create Controller

Now, create a controller to upload image. Create a controller named ImageUploadController using command given below –

php artisan make:controller dropzone_image_upload/ImageUploadController

1	php artisan make:controller dropzone_image_upload/ImageUploadController

Once the above command executed, it will create a controller file ImageUploadController.php in app/Http/Controllers/dropzone_image_upload/ directory. Open the ImageUploadController.php file and put the following code in it.

app/Http/Controllers/dropzone_image_upload/ImageUploadController.php

<?php

namespace App\Http\Controllers\dropzone_image_upload;

use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use Validator,Redirect,Response,File;
use App\Photo;

class ImageUploadController extends Controller
{
    //
    public function index()
    {
        return view('dropzone_image_upload.index');
    }

    public function store(Request $request)
    {
        $image = $request->file('file');
        $profileImage = $image->getClientOriginalName();
        // Define upload path
        $destinationPath = public_path('/profile_images/'); // upload path
        $image->move($destinationPath,$profileImage);
        
        // Save In Database
		$imagemodel= new Photo();
		$imagemodel->photo_name="$profileImage";
		$imagemodel->save();
        return response()->json(['success'=>$profileImage]);
    }

    public function destroy(Request $request)
    {
        $filename =  $request->get('filename');
        Photo::where('photo_name',$filename)->delete();
        $path=public_path('/profile_images/').$filename;
        if (file_exists($path)) {
            unlink($path);
        }
        return $filename;  
    }
}

<?php

namespace App\Http\Controllers\dropzone_image_upload;

use Illuminate\Http\Request;

use App\Http\Controllers\Controller;

use Validator,Redirect,Response,File;

use App\Photo;

class ImageUploadController extends Controller

{

public function index()

{

return view('dropzone_image_upload.index');

}

public function store(Request $request)

{

$image = $request->file('file');

$profileImage = $image->getClientOriginalName();

// Define upload path

$destinationPath = public_path('/profile_images/'); // upload path

$image->move($destinationPath,$profileImage);

// Save In Database

$imagemodel= new Photo();

$imagemodel->photo_name="$profileImage";

$imagemodel->save();

return response()->json(['success'=>$profileImage]);

}

public function destroy(Request $request)

{

$filename = $request->get('filename');

Photo::where('photo_name',$filename)->delete();

$path=public_path('/profile_images/').$filename;

if (file_exists($path)) {

unlink($path);

}

return $filename;

}

Here In the controller, we have following methods –

index() :- It displays Drozone Multiple Image Upload Form

store() :- To Upload using Dropzone and Save Multiple Image in database.

destroy() :- To delete files from directory and database.

Note:- Before uploading any file make sure you have created following two directory in the public folder called profile_images.

Create Blade / View Files

In this step, we will create view/blade file to display Image Upload Form using Dropzone. Lets create a blade file “index.blade.php” in “resources/views/dropzone_image_upload/” directory.

Include Dropzone Javascript and CSS files

In order to use dropzone plugin we need to include following Dropzone javascript and CSS files in your laravel blade file.

Dropzone CSS :-

In this file we will be adding dropzone.min.css along with the our bootstrap.min.css as following –

Dropzone Javascript :-

Here we will add dropzone.js file along with the jquery.js as following –

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/dropzone/5.4.0/dropzone.js"></script>

1 2	<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/dropzone/5.4.0/dropzone.js"></script>

Configure Dropzone Plugin with Remove Image Link

Next, we will provide initial configurations for Dropzone plugin.We setup follwoing dropzone options –

maxFilesize:- Maximum Image size that can be uploaded.

renameFile:- It is used to rename the file before uploading.

acceptedFiles:- File types or extension that can be uploaded.

addRemoveLinks:- It is set to true to display Remove button to remove uploaded file.

removedfile:- It is a callback function invoked when image is removed from dropzone.

Now, our blade file will look something like this.

resources/views/dropzone_image_upload/index.blade.php

Create Routes

After this, we need to add following dropzone image upload routes in “routes/web.php” file along with a resource route. Lets open “routes/web.php” file and add following route.

routes/web.php

Route::get('dropzone-image-upload', 'dropzone_image_upload\ImageUploadController@index');
Route::post('dropzone-image-upload', 'dropzone_image_upload\ImageUploadController@store');
Route::post('dropzone-image-delete', 'dropzone_image_upload\ImageUploadController@destroy');

Route::get('dropzone-image-upload', 'dropzone_image_upload\ImageUploadController@index');

Route::post('dropzone-image-upload', 'dropzone_image_upload\ImageUploadController@store');

Route::post('dropzone-image-delete', 'dropzone_image_upload\ImageUploadController@destroy');

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

php artisan serve

1	php artisan serve

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

http://localhost:8000/dropzone-image-upload

Output:-

laravel-5-8-dropzone-multiple-image-upload-1

After Image Upload Screen Output:-

Select and Drop Multiple Image files to upload using dropzone.
