Multiple Images Upload in Laravel with Validation

vinoy · 3 years ago · 3012 Views

Many developers face difficulties in adding image upload feature in the application. Specifically, developers are uncertain about how to upload and validate images. In this post, you will learn how to implement Laravel multiple image upload functionality with validations.

Create Laravel Project

To create a Laravel app, run the following command in the terminal:

composer create-project laravel/laravel --prefer-dist laravel-app
cd laravel-app

Database Configuration

Create database and define your database configuration in .env file.

DB_CONNECTION=mysql
DB_HOST=localhost
DB_PORT=3306
DB_DATABASE=laravel_db
DB_USERNAME=root
DB_PASSWORD=

Create Image Model and Migrations

To create Image model and images table migration use following command:

php artisan make:model Image -m

Now go to the database/migration directory and open the migration file for the images table. In this migration, add column image_path.

<?php

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

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

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

Next, run the migration to create tables in the database.

php artisan migrate

Create Routes in Laravel

Go to routes/web.php and create two routes. One route to show image upload form, and the second route is to upload the image.

// Create image upload form
Route::get('/images/upload', 'ImageUploadController@show');

// Store image
Route::post('/images/upload', 'ImageUploadController@store')->name('images.store');

Create Image Uploading Controller

Run the following command to create ImageUploadController:

php make:controller ImageUploadController

Next, in the Go to app/Http/Controllers/ImageUploadController.php file, we need to create a show() method to display image upload form and store() method to upload images as shown in the following code snippet:

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Image;

class ImageUploadController extends Controller
{
  public function show()
  {
    return view('images.show');
  }

  public function store(Request $request)
  {
        $request->validate([
        	'file' => 'required|image|max:2048'
        ]);

        $imageModel = new Image;

        if($request->file()) {
            $imagePath = $request->file('file')->store('uploads');
            
            $imageModel->image_path = '/uploads/' . $imagePath;
            $imageModel->save();

            return back()
	    ->with('success','Image has been uploaded.')
	    ->with('file', $imagePath);
        }
   }
}

Create Blade Template for image upload form

Create resources\views\images\show.blade.php file and add the following code.

<!doctype html>
<html lang="en">

<head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
    <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.0/css/bootstrap.min.css">

    <title>Laravel Image Upload</title>
    <style>
        .container {
            max-width: 500px;
        }
        dl, ol, ul {
            margin: 0;
            padding: 0;
            list-style: none;
        }
        .imgPreview img {
            padding: 8px;
            max-width: 100px;
        } 
    </style>
</head>

<body>

    <div class="container mt-5">
        <h3 class="text-center mb-5">Image Upload in Laravel</h3>
        <form action="{{route('imageUpload')}}" method="post" enctype="multipart/form-data">
            @csrf
            @if ($message = Session::get('success'))
                <div class="alert alert-success">
                    <strong>{{ $message }}</strong>
                </div>
            @endif

            @if (count($errors) > 0)
                <div class="alert alert-danger">
                    <ul>
                        @foreach ($errors->all() as $error)
                        <li>{{ $error }}</li>
                        @endforeach
                    </ul>
                </div>
            @endif

            <div class="user-image mb-3 text-center">
                <div class="imgPreview"> </div>
            </div>            

            <div class="custom-file">
                <input type="file" name="imageFile[]" class="custom-file-input" id="images" multiple="multiple">
                <label class="custom-file-label" for="images">Choose image</label>
            </div>

            <button type="submit" name="submit" class="btn btn-primary btn-block mt-4">
                Upload Images
            </button>
        </form>
    </div>
  
    <!-- jQuery -->
    <script src="https://code.jquery.com/jquery-3.5.1.slim.min.js"></script>
    <script>
        $(function() {
        // Multiple images preview with JavaScript
        var multiImgPreview = function(input, imgPreviewPlaceholder) {

            if (input.files) {
                var filesAmount = input.files.length;

                for (i = 0; i < filesAmount; i++) {
                    var reader = new FileReader();

                    reader.onload = function(event) {
                        $($.parseHTML('<img>')).attr('src', event.target.result).appendTo(imgPreviewPlaceholder);
                    }

                    reader.readAsDataURL(input.files[i]);
                }
            }

        };

        $('#images').on('change', function() {
            multiImgPreview(this, 'div.imgPreview');
        });
        });    
    </script>
</body>
</html>

Finally, we have completed the Laravel Image upload feature. Its time to run this in browser. So, in your terminal run following command:

php artisan serve

Now test this URL path (http://127.0.0.1:8000//images/upload) in your browser.
