Conclusion

Install Laravel App

First, we need to download the Laravel fresh setup. Use the below command and download fresh new Laravel setup :

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

Setup Database

After successfully install Laravel Application, Go to your project .env file and set up database credential and move next step :

 DB_CONNECTION=mysql 
 DB_HOST=127.0.0.1 
 DB_PORT=3306 
 DB_DATABASE=here your database name here
 DB_USERNAME=here database username here
 DB_PASSWORD=here database password here

Generate Migration & Model

Now we will create a table named documents and it’s migration file. use the below command :

php artisan make:model document -m

Its command will create one model name file and also create one migration file for the file table. After successfully run the command go to database/migrations file and put the below here :

<?php
 
use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
 
class CreatedocumentsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('files', function (Blueprint $table) {
            $table->increments('id');
            $table->string('name');
            $table->timestamps();
        });
    }
 
    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('documents');
    }
}

Next, migrate the table using the below command :

php artisan migrate

Make Route

We will create two routes in the web.php file. Go to app/routes/web.php file and create two below routes here :

 Route::get('file', 'fileController@index');
 Route::get('save', 'fileController@save');

Create Controller

We need to create a controller name FileController. Use the below command and create Controller :

php artisan make:controller FileController

After successfully create controller go to app/controllers/FileController.php and put the below code :

<?php
 
namespace App\Http\Controllers;
 
use Illuminate\Http\Request;
use Validator,Redirect,Response,File;
Use App\Document;
 
class FileController extends Controller
{
 
    public function index()
    {
        return view('file');
    }
 
    public function save()
    {
       request()->validate([
         'file'  => 'required|mimes:doc,docx,pdf,txt|max:2048',
       ]);
 
       if ($files = $request->file('fileUpload')) {
           $destinationPath = 'public/file/'; // upload path
           $profilefile = date('YmdHis') . "." . $files->getClientOriginalExtension();
           $files->move($destinationPath, $profilefile);
           $insert['file'] = "$profilefile";
        }
         
        $check = Document::insertGetId($insert);
 
        return Redirect::to("file")
        ->withSuccess('Great! file has been successfully uploaded.');
 
    }
}

Create Blade view

In this step, we need to create a blade view file. Go to app/resources/views and create one file name file.blade.php :

<html lang="en" class="">
<head>
<meta charset="UTF-8">

            @if ($message = Session::get('success'))
 
                <div class="alert alert-success alert-block">
 
                    <button type="button" class="close" data-dismiss="alert">×</button>
 
                    <strong>{{ $message }}</strong>
 
                </div>
            @endif
 
            @if (count($errors) > 0)
                <div class="alert alert-danger">
                    <strong>Whoops!</strong> There were some problems with your input.<br><br>
                    <ul>
                        @foreach ($errors->all() as $error)
                            <li>{{ $error }}</li>
                        @endforeach
                    </ul>
                </div>
            @endif
 
            <form action="/file" method="post" enctype="multipart/form-data">
                @csrf
                <div class="form-group">
                    <input type="file" class="form-control-file" name="file" id="file" aria-describedby="fileHelp">
                    <small id="fileHelp" class="form-text text-muted">Please upload a valid image file. Size of image should not be more than 2MB.</small>
                </div>
                <button type="submit" class="btn btn-primary">Submit</button>
            </form>
 
         </div>
     </div>
  </div>
</div>
</html>
