Laravel 8 Multiple Images Upload with Validation Example

In this step by step tutorial I’ll demonstrate example of multiple image upload with Validation in laravel 8. Please follow the step given below:

Create Project
Database Configuration

Create Model and Migrations
Create Controller
Create Routes

Create Blade File

Create Laravel Project

First of all we need to create a fresh laravel project, download and install Laravel 8 using the below command

composer create-project laravel/laravel --prefer-dist laravel-image-upload

1	composer create-project laravel/laravel --prefer-dist laravel-image-upload

Now switch to the project directory.

cd laravel-image-upload

1	cd laravel-image-upload

Database Configuration

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=localhost
DB_PORT=3306
DB_DATABASE=laravel_db
DB_USERNAME=root
DB_PASSWORD=

DB_CONNECTION=mysql

DB_HOST=localhost

DB_PORT=3306

DB_DATABASE=laravel_db

DB_USERNAME=root

DB_PASSWORD=

Create Model and Migrations

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

php artisan make:model Image -m

1	php artisan make:model Image -m

Once above command is executed there will be a migration file created inside database/migrations/ directory, open migration file and update the function up() method as following:

<?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('name')->nullable();
            $table->string('image_path')->nullable();
            $table->timestamps();
        });
    }

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

<?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('name')->nullable();

$table->string('image_path')->nullable();

$table->timestamps();

});

}

/**

* Reverse the migrations.

* @return void

public function down()

{

Schema::dropIfExists('images');

}

Now put the following code inside the app/Models/Image.php file.

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Image extends Model
{
    use HasFactory;
    protected $fillable = [
        'name',
        'image_path'
    ];

}

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;

use Illuminate\Database\Eloquent\Model;

class Image extends Model

{

use HasFactory;

protected $fillable = [

'name',

'image_path'

];

}

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

php artisan migrate

1	php artisan migrate

Create Image Uploading Controller

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

php artisan make:controller FileUpload

1	php artisan make:controller FileUpload

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

app/Http/Controllers/FileUpload.php

<?php

namespace App\Http\Controllers;

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

class FileUpload extends Controller
{
  public function createForm(){
    return view('image-upload');
  }


  public function fileUpload(Request $req){
    $req->validate([
      'imageFile' => 'required',
      'imageFile.*' => 'mimes:jpeg,jpg,png,gif,csv,txt,pdf|max:2048'
    ]);

    if($req->hasfile('imageFile')) {
        foreach($req->file('imageFile') as $file)
        {
            $name = $file->getClientOriginalName();
            $file->move(public_path().'/uploads/', $name);  
            $imgData[] = $name;  
        }

        $fileModal = new Image();
        $fileModal->name = json_encode($imgData);
        $fileModal->image_path = json_encode($imgData);
        
       
        $fileModal->save();

       return back()->with('success', 'File has successfully uploaded!');
    }
  }
}

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Models\Image;

class FileUpload extends Controller

{

public function createForm(){

return view('image-upload');

}

public function fileUpload(Request $req){

$req->validate([

'imageFile' => 'required',

'imageFile.*' => 'mimes:jpeg,jpg,png,gif,csv,txt,pdf|max:2048'

]);

if($req->hasfile('imageFile')) {

foreach($req->file('imageFile') as $file)

{

$name = $file->getClientOriginalName();

$file->move(public_path().'/uploads/', $name);

$imgData[] = $name;

}

$fileModal = new Image();

$fileModal->name = json_encode($imgData);

$fileModal->image_path = json_encode($imgData);

$fileModal->save();

return back()->with('success', 'File has successfully uploaded!');

}

The createForm() function will display image upload from in the view, and the the fileUpload() method will handle uploading, storing and validation in the image uploading controller.

Create Routes in Laravel

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

<?php

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

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

Route::get('/image-upload', [FileUpload::class, 'createForm']);

Route::post('/image-upload', [FileUpload::class, 'fileUpload'])->name('imageUpload');

<?php

use Illuminate\Support\Facades\Route;

use App\Http\Controllers\FileUpload;

|--------------------------------------------------------------------------

| 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!

Route::get('/image-upload', [FileUpload::class, 'createForm']);

Route::post('/image-upload', [FileUpload::class, 'fileUpload'])->name('imageUpload');

Create Blade Template

In this step we will create blade view file for uploading multiple images. Create resources\views\image-upload.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">

        .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">

                <div class="alert alert-success">
                    <strong>{{ $message }}</strong>
                </div>
            @endif

            @if (count($errors) > 0)
                <div class="alert alert-danger">

                        @foreach ($errors->all() as $error)
                        <li>{{ $error }}</li>
                        @endforeach

                var filesAmount = input.files.length;

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

                    reader.onload = function(event) {

                    }

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

        };

        $('#images').on('change', function() {
