Laravel 8 File Upload to Database With Validation

Simple steps to file uploading in laravel 8 app:

  • Step 1 – Install Laravel 8 Application
  • Step 2 – Configuring Database Details
  • Step 3 – Create File Model & Migration
  • Step 4 – Create File Upload Routes
  • Step 5 – Creating File Upload Controller
  • Step 6 – Create File Upload Blade View
  • Step 7 – Start Development Server
  • Step 8 – Run Laravel 8 File Upload with Validation App On Browser

Step 1 – Install Laravel 8 Application

In step 1, open your terminal and navigate to your local web server directory using the following command:

//for windows user
cd xampp/htdocs

//for ubuntu user
cd var/www/html

Then install laravel 8 latest application using the following command:

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

Step 2 – Configuring Database Details

In step 2, open your downloaded laravel 8 app into any text editor. Then find .env file and configure database detail like following:

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=db name
DB_USERNAME=db user name
DB_PASSWORD=db password

Step 3 – Create File Model & Migration

In step 3, open command prompt and navigate to your project by using the following command:

cd / LaravelFileUpload

Then create model and migration file by using the following command:

php artisan make:model File -m

The above command will create two files into your laravel 8 file upload tutorial app, which is located inside the following locations:

  • LaravelFileUpload/app/Models/File.php
  • LaravelFileUpload/database/migrations/create_files_table.php

So, find create_files_table.php file inside LaravelFileUpload/database/migrations/ directory. Then open this file and add the following code into function up() on this file:

    public function up()
    {
        Schema::create('files', function (Blueprint $table) {
            $table->id();
            $table->string('name');
            $table->string('path');
            $table->timestamps();
        });
    }

Now, open again your terminal and type the following command on cmd to create tables into your selected database:

php artisan migrate

Step 4 – Create File Upload Routes

In step 4, open your web.php file, which is located inside routes directory. Then add the following routes into web.php file:

<?php

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


/*
|--------------------------------------------------------------------------
| 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('/', function () {
    return view('welcome');
});


Route::get('file-upload', [FileUploadController::class, 'index']);
Route::post('file-store', [FileUploadController::class, 'storeFile']);

Step 5 – Creating File Upload Controller

In step 5, create file upload controller by using the following command:

php artisan make:controller FileUploadController

The above command will create FileUploadController.php file, which is located inside LaravelFileUpload/app/Http/Controllers/ directory.

The following laravel validation rules will validate file before upload/save into database:

        $validatedData = $request->validate([
          'file' => 'required|mimes:csv,txt,xlx,xls,pdf|max:2048'
        ]);

So open FileController.php file and add the following code into it:

<?php

namespace App\Http\Controllers;

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

class FileUploadController extends Controller
{
     public function index()
    {
        return view('file-upload');
    }

    public function storeFile(Request $request)
    {
        
        $validatedData = $request->validate([
          'file' => 'required|mimes:csv,txt,xlx,xls,pdf|max:2048'
        ]);

        $name = $request->file('file')->getClientOriginalName();

        $path = $request->file('file')->store('public/files');


        $save = new File;

        $save->name = $name;
        $save->path = $path;

        $save->save();

        return redirect('file-upload')->with('status', 'File Has been uploaded');

    }
}

The following single line of code will upload files inside storage/app/public/files directory:

        $path = $request->file('file')->store('public/files');

Step 6 – Create File Upload Blade View

In step 6, create new blade view file that named file-upload.php inside resources/views directory for file upload form.

The following code display error message in laravel file upload forms. So do not forget to add the following code along laravel forms fields:

          @error('file')
              <div class="alert alert-danger mt-1 mb-1">{{ $message }}</div>
          @enderror

Don’t worry i have already added the validation error message display code along with form fields.

So, you can add the following php and html form code into file-upload.blade.php:

<!DOCTYPE html>
<html>
<head>
  <title>Laravel 8 File Upload Tutorial</title>

  <meta name="csrf-token" content="{{ csrf_token() }}">

  <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css">

</head>
<body>

<div class="container mt-4">

  <div class="card">

    <div class="card-header text-center font-weight-bold">
      <h2>Laravel 8 File Upload Tutorial</h2>
    </div>

    <div class="card-body">
        <form method="POST" enctype="multipart/form-data" id="file-upload" action="{{ url('file-store') }}" >
                  
            <div class="row">

                <div class="col-md-12">
                    <div class="form-group">
                        <input type="file" name="file" placeholder="Choose file " id="file">
          @error('file')
              <div class="alert alert-danger mt-1 mb-1">{{ $message }}</div>
          @enderror
                    </div>
                </div>
                  
                <div class="col-md-12">
                    <button type="submit" class="btn btn-primary" id="submit">Submit</button>
                </div>
            </div>     
        </form>

    </div>

  </div>

</div>  
</body>
</html>

Step 7 – Start Development Server

Finally, open your command prompt again and run the following command to start development server for your laravel 8 file upload application:

php artisan serve

Step 8 – Run Laravel 8 File Upload with Validation App On Browser

In step 8, open your browser and fire the following url into your browser:

http://127.0.0.1:8000/file-upload
