laravel file upload

In this post, I will be going to share how to implement a simple Laravel 9 file upload with a database implementation. We will save the generated file name base on time, size, and mime-type, and associate it with the current user logged. When developing an application using Laravel usually the file upload is always present even on a simple system.

Just follow my simple steps and learn from them.

 

 

Laravel File Upload

I assume that you have your Laravel 9 Project already in your local so we will skip that process. For more information on how to install Laravel just visit their documentation.

 

Okay, let's start.

 

 

Step 1: Create file upload migrations

First, we will create our file table migrations for our File model. Run the following command to do it:

php artisan make:migration create_files_table

 

Then we will add our migrations field. See below the complete code for our migrations.

<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

class CreateFilesTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('files', function (Blueprint $table) {
            $table->id();
            $table->unsignedBigInteger('user_id');
            $table->string('name');
            $table->string('type');
            $table->string('size');
            $table->timestamps();

            $table->foreign('user_id')
                ->references('id')
                ->on('users')
                ->onDelete('cascade');
        });
    }

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

 

Next, you have to run:

php artisan migrate

 

Step 2: Create file upload controller and model

Use the command below to create your FileController with the File model:

php artisan make:controller FilesController --model=File

 

Step 3: Create Laravel file upload routes

Now, let's create your routes for our Laravel file upload:

/**
* File Upload Routes
*/
Route::get('/files', 'FilesController@index')->name('files.index');
Route::get('/files/add', 'FilesController@create')->name('files.create');
Route::post('/files/add', 'FilesController@store')->name('files.store');

 

Step 4: Setup Model

Next, we will set up our File model. See below the completed setup.

<?php

namespace App\Models;

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

class File extends Model
{

    protected $table = 'files';

    protected $fillable = [
        'user_id',
        'name',
        'type',
        'size'
    ];

    use HasFactory;
}

 

Step 5: Setup Controller

Kindly see below the complete code of our controller including the file upload in store() method.

<?php

namespace App\Http\Controllers;

use App\Models\File;
use Illuminate\Http\Request;
use Illuminate\Http\UploadedFile;
use App\Http\Requests\StoreFileRequest;

class FilesController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        $files = File::all();

        return view('files.index', [
            'files' => $files
        ]);
    }

    /**
     * Show the form for creating a new resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function create()
    {
        return view('files.create');
    }

    /**
     * Store a newly created resource in storage.
     *
     * @param  StoreFileRequest  $request
     * @return \Illuminate\Http\Response
     */
    public function store(StoreFileRequest $request)
    {
        $fileName = auth()->id() . '_' . time() . '.'. $request->file->extension();  

        $type = $request->file->getClientMimeType();
        $size = $request->file->getSize();

        $request->file->move(public_path('file'), $fileName);

        File::create([
            'user_id' => auth()->id(),
            'name' => $fileName,
            'type' => $type,
            'size' => $size
        ]);

        return redirect()->route('files.index')->withSuccess(__('File added successfully.'));
    }

}

 

Step 6: Create StoreFileRequest

Now let's create a request class for a store/uploading file. Run the command below:

php artisan make:request StoreFileRequest

 

After the StoreFileRequest class is generated kindly check the code below for our validation:

<?php

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;

class StoreFileRequest extends FormRequest
{
    /**
     * Determine if the user is authorized to make this request.
     *
     * @return bool
     */
    public function authorize()
    {
        return true;
    }

    /**
     * Get the validation rules that apply to the request.
     *
     * @return array
     */
    public function rules()
    {
        return [
            'file' => 'required|file|mimes:jpg,jpeg,bmp,png,doc,docx,csv,rtf,xlsx,xls,txt,pdf,zip'
        ];
    }
}

 

Step 7: Create View

First, we will create our index.blade.php see below the complete code:

@extends('layouts.app-master')

@section('content')
    <div class="bg-light p-5 rounded">
        <h1>Files</h1>
        <a href="{{ route('files.create') }}" class="btn btn-primary float-right mb-3">Add file</a>

        @include('layouts.partials.messages')

        <table class="table table-striped">
          <thead>
            <tr>
              <th scope="col">#</th>
              <th scope="col">Name</th>
              <th scope="col">Size</th>
              <th scope="col">Type</th>
              <th scope="col">Action</th>
            </tr>
          </thead>
          <tbody>
            @foreach($files as $file)
              <tr>
                <td width="3%">{{ $file->id }}</td>
                <td>{{ $file->name }}</td>
                <td width="10%">{{ $file->size }}</td>
                <td width="10%">{{ $file->type }}</td>
                <td width="5%"><a href="{{ $file->type }}" class="btn btn-danger btn-sm">Delete</a></td>
              </tr>
            @endforeach
          </tbody>
        </table>
    </div>
@endsection

 

Second, create.blade.php for our uploading file.

@extends('layouts.app-master')

@section('content')
    <div class="bg-light p-5 rounded">
        <h1>Add file</h1>
        
        <form action="{{ route('files.store') }}" method="post" enctype="multipart/form-data">
            @include('layouts.partials.messages')
            @csrf
            <div class="form-group mt-4">
              <input type="file" name="file" class="form-control" accept=".jpg,.jpeg,.bmp,.png,.gif,.doc,.docx,.csv,.rtf,.xlsx,.xls,.txt,.pdf,.zip">
            </div>

            <button class="w-100 btn btn-lg btn-primary mt-4" type="submit">Save</button>
        </form>

    </div>
@endsection

 

As you can see from our input=file we added accept attribute with a value of ".jpg,.jpeg,.bmp,.png,.gif,.doc,.docx,.csv,.rtf,.xlsx,.xls,.txt,.pdf,.zip" it will help to only accept base on specified file extensions.
