Laravel Upload Multiple Images and Files with Validation

Published on April 4, 2020 2 min read

In this article, I’m going to show how to upload multiple images and files with validation. I’m testing in Laravel 7. Let’s get started:

Table of Contents

  1. Create Model, Migration & Controller
  2. Config Model & Migration
  3. Add Methods to Controller
  4. Create View
  5. Define Routes
  6. Run & Test

Create Model, Migration & Controller

Let’s create a model, migration and controller for file upload. Run this command to create all three at once:

php artisan make:model FileUpload -mc

Config Model & Migration

Open FileUpload model from app folder and add this code:

FileUpload.php
<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class FileUpload extends Model
{
    protected $fillable = [ 'filename' ];
}

Open the migration file from database/migrations folder and update up() function like this:

timestamp_create_file_uploads_table.php
public function up()
{
    Schema::create('file_uploads', function (Blueprint $table) {
        $table->id();
        $table->string('filename');
        $table->timestamps();
    });
}

Add Methods to Controller

I’m going to create two methods. One for view and another for upload file. Open the controller from app/Http/Controller and paste this code:

FileUploadController.php
<?php

namespace App\Http\Controllers;

use App\FileUpload;
use Illuminate\Http\Request;

class FileUploadController extends Controller
{
    // show form
    public function index() {
        return view('upload');
    }

    // file upload
    public function upload(Request $request)
    {
        $validator = \Validator::make($request->all(), [
            'files' => 'required'
        ])->validate();

        $total_files = count($request->file('files'));

        foreach ($request->file('files') as $file) {
            // rename & upload files to uploads folder
            $name = uniqid() . '_' . time(). '.' . $file->getClientOriginalExtension();
            $path = public_path() . '/uploads';
            $file->move($path, $name);

            // store in db
            $fileUpload = new FileUpload();
            $fileUpload->filename = $name;
            $fileUpload->save();
        }

        return back()->with("success", $total_files . " files uploaded successfully");
    }
}

Create View

Go to resources/views folder and create a blade file named upload.blade.php. Then paste this code:

upload.blade.php
@extends('layouts.app')

@section('content')
    <div class="container">
        <div class="row justify-content-center">
            <div class="col-md-8">
                <div class="card">
                    <div class="card-header">File Uploader</div>

                    <div class="card-body">

                        <!-- print success message after file upload  -->
                        @if(Session::has('success'))
                            <div class="alert alert-success">
                                {{ Session::get('success') }}
                                @php
                                    Session::forget('success');
                                @endphp
                            </div>
                        @endif

                        <form method="post" action="{{ route('upload') }}" enctype="multipart/form-data">
                            {{ csrf_field() }}

                            <div class="form-group">
                                <label for="title">Image/file</label>
                                <input type="file" name="files[]" class="form-control-file" multiple="">
                                @if($errors->has('files'))
                                    <span class="help-block text-danger">{{ $errors->first('files') }}</span>
                                @endif
                            </div>

                            <div class="text-center">
                                <button class="btn btn-primary">Upload</button>
                            </div>
                        </form>
                    </div>
                </div>
            </div>
        </div>
    </div>

Define Routes

Open routes/web.php file and define two routes:

web.php
Route::get('upload', '[email protected]');
Route::post('upload', '[email protected]')->name('upload');

Run & Test

Our application is ready. Let’s run (php artisan serve) our application and visit upload route and test.
