laravel 多檔案上傳

============================================================
*資料庫:
news
news_file

*laravel 檔案:
model
migration
controller
route

*postman:
title
content
photo (單一檔案)
file[] (多個檔案)(使用陣列)

============================================================
*資料庫:

news:

id            int auto key
title        vc
content        text
photo        vc

migration:

$table->id();
$table->string('title');
$table->text('content');
$table->string('photo');
$table->timestamps();

--------------------------------
news_file:

id            int auto key
news_id        int
file_name    vc                檔案名稱
org_name    vc                檔案原始名稱

migration:

$table->id();
$table->unsignedBigInteger('news_id');
$table->string('file_name');
$table->string('org_name');
$table->timestamps();

============================================================
*laravel 檔案:

model
migration
controller

route

--------------------------------
php artisan make:model news -rmc

--------------------------------
route:

use App\Http\Controllers\NewsController;

Route::apiResource('news', NewsController::class);

php artisan route:list

============================================================
*新增

| POST | api/news | news.store | App\Http\Controllers\NewsController@store | api |

POST

http://localhost/animal/public/api/news

============================================================
app\Models\news.php

<?php

namespace App\Models;

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

class news extends Model
{
    use HasFactory;

    //可以被批量寫入的屬性
    protected $fillable = [
        'title',
        'content',
        'photo',
    ];
}

============================================================
app\Models\news_file.php

<?php

namespace App\Models;

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

class news_file extends Model
{
    use HasFactory;

    //可以被批量寫入的屬性
    protected $fillable = [
        'news_id',
        'file_name',
        'org_name',
    ];
}

============================================================
*多檔上傳:

1.把檔案儲存到uploads資料夾

2.把檔案資料儲存到: 資料表 news_file
news_id
file_name
org_name

3.回傳資料
