Install Laravel Fresh New Setup
Setup Database Credentials
Generate Migration & Model

Add Route
Create Controller & Methods
Create Blade View

Run Development Server

1). Install Laravel Fresh New Setup

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

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

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

2). Setup Database Credentials

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=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

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

3). Generate Migration & Model

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

php artisan make:model document -m

1	php artisan make:model document -m

The above command will create a model name file and also create a migration file for the file table. After successfully run the command go to database/migrations file and put the following code in it:

<?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('documents', function (Blueprint $table) {
            $table->increments('id');
            $table->string('title');
            $table->timestamps();
        });
    }
 
    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('documents');
    }
}

<?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('documents', function (Blueprint $table) {

$table->increments('id');

$table->string('title');

$table->timestamps();

});

}

/**

* Reverse the migrations.

* @return void

public function down()

{

Schema::dropIfExists('documents');

}

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

php artisan migrate

1	php artisan migrate

4). Add Route

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

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

1 2	Route::get('file', 'FileController@index'); Route::post('save', 'FileController@save');

5). Create Controller

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

php artisan make:controller FileController

1	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);
           $insert['title'] = "$profilefile";
        }
         
        $check = Document::insertGetId($insert);
 
        return Redirect::to("file")
        ->withSuccess('Great! file has been successfully uploaded.');
 
    }
}

<?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);

$insert['title'] = "$profilefile";

}

$check = Document::insertGetId($insert);

return Redirect::to("file")

->withSuccess('Great! file has been successfully uploaded.');

}

6). Create Blade view

In this step we will 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">

<body>
<div class="container">
  <div class="row justify-content-center">
    <div class="card">
       <div class="card-header">Laravel Upload File Example</div>
 
         <div class="card-body">
            @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="/save" 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>

<head>

<title>Laravel File Upload Tutorial Example From Scratch</title>

</head>

<body>

<div class="card-header">Laravel Upload File Example</div>

@if ($message = Session::get('success'))

<strong>{{ $message }}</strong>

</div>

@endif

@if (count($errors) > 0)

<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

@csrf

<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>

</html>

7). Run Development Server

Now we are ready to run our example so lets start the development server using following artisan command –

php artisan serve

1	php artisan serve

Now, open the following URL in browser to see the output –

http://localhost:8000/file
 OR hit in browser
 http://localhost/blog/public/file

http://localhost:8000/file

OR hit in browser

http://localhost/blog/public/file
