Multiple File Images Upload Trong Laravel
Bài đăng này đã không được cập nhật trong 2 năm
Hi mọi người.
Bài viết này mình sẽ chia sẻ cách upload multiple file images trong laravel 8. Ở ví dụ mình demo sẽ bao gồm các chức năng như create, edit file images.
Các bạn hãy theo dõi các bước bên dưới để hiểu hơn nhé.
Màn hình Preview create.
Màn hình Preview edit.
Step1: Tạo Migration và Model
Mình sẽ tạo migration và model cho table files như bên dưới nhé
php artisan make:migration create_files_table
Migration:
<?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->string('filenames');
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::dropIfExists('files');
}
}
Chạy migration bằng command bên dưới.
php artisan migrate
Tiếp theo mình sẽ tạo model file bằng command bên dưới.
php artisan make:model File
app/Models/File.php
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
class File extends Model
{
use HasFactory;
protected $fillable = [
'filenames'
];
/**
* Set the user's first name.
*
* @param string $value
* @return void
*/
public function setFilenamesAttribute($value)
{
$this->attributes['filenames'] = json_encode($value);
}
}
Step2: Create Routes
Mình sẽ tạo 4 routes như bên dưới để demo chức năng upload, edit ảnh nhé.
<?php
use Illuminate\Support\Facades\Route;
/*
|--------------------------------------------------------------------------
| 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('create/', 'FileController@create');
Route::post('create/', 'FileController@store');
Route::get('edit/{id}', 'FileController@edit')->name('file.edit');
Route::post('edit/', 'FileController@update');
Step3: Create Controller
app/Http/Controllers/FileController.php
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\File;
use Illuminate\Support\Facades\File as File2;
class FileController extends Controller
{
/**
* Show the application dashboard.
*
* @return \Illuminate\Http\Response
*/
public function create()
{
$files = File::all();
return view('create', ['files' => $files]);
}
/**
* Show the application dashboard.
*
* @return \Illuminate\Http\Response
*/
public function store(Request $request)
{
$this->validate($request, [
'filenames' => 'required',
'filenames.*' => 'required'
]);
$files = [];
if($request->hasfile('filenames'))
{
foreach($request->file('filenames') as $file)
{
$name = time().rand(1,100).'.'.$file->extension();
$file->move(public_path('files'), $name);
$files[] = $name;
}
}
$file= new File();
$file->filenames = $files;
$file->save();
return back()->with('success', 'Data Your files has been successfully added');
}
/**
* Show the application dashboard.
*
* @return \Illuminate\Http\Response
*/
public function edit($id)
{
$files = File::find($id);
return view('create', ['list_images' => $files->filenames, 'id' => $id]);
}
/**
* Show the application dashboard.
*
* @return \Illuminate\Http\Response
*/
public function update(Request $request)
{
$input = $request->all();
$files = [];
$files_remove = [];
if($request->hasfile('filenames'))
{
foreach($request->file('filenames') as $file)
{
$name = time().rand(1,100).'.'.$file->extension();
$file->move(public_path('files'), $name);
$files[] = $name;
}
}
if (isset($input['images_uploaded'])) {
$files_remove = array_diff(json_decode($input['images_uploaded_origin']), $input['images_uploaded']);
$files = array_merge($input['images_uploaded'], $files);
} else {
$files_remove = json_decode($input['images_uploaded_origin']);
}
$file = File::find($input['id']);
$file->filenames = $files;
if($file->update()) {
foreach ($files_remove as $file_name) {
File2::delete(public_path("files/".$file_name));
}
}
return back()->with('success', 'Data Your files has been successfully updated');
}
}
Tham khảo 3 cách lưu ảnh vào thư mục nhé.
Store File in Storage Folder
$file->storeAs('files', $imageName);
// storage/app/files/file.png
Store File in Public Folder
$file->move(public_path('files'), $imageName);
// public/files/file.png
Store File in S3
$file->storeAs('files', $imageName, 's3');
Step4: Create Blade File
Bước này mình sẽ tạo file create.blade.php trong resources nhé.
resources/views/create.blade.php

Cuối cùng là chạy và kiểm tra code đã hoạt động hay chưa .
