如何检查表格是否以laravel格式提交？

use Illuminate\Http\Request;

class YourController extends Controller
{
    public function store(Request $request)
    {
        // 定义验证规则
        $rules = [
            'name' => 'required|string|max:255',
            'email' => 'required|email|unique:users',
            'password' => 'required|min:8|confirmed',
        ];

        // 执行验证
        $validatedData = $request->validate($rules);

        // 如果验证通过，继续处理数据
        // ...

        return response()->json(['message' => 'Data is valid'], 200);
    }
}

@if ($errors->any())
    <div class="alert alert-danger">
        <ul>
            @foreach ($errors->all() as $error)
                <li>{{ $error }}</li>
            @endforeach
        </ul>
    </div>
@endif

php artisan make:rule CustomRule

namespace App\Rules;

use Illuminate\Contracts\Validation\Rule;

class CustomRule implements Rule
{
    public function passes($attribute, $value)
    {
        // 自定义验证逻辑
        return $value === 'expected_value';
    }

    public function message()
    {
        return 'The :attribute must be "expected_value".';
    }
}

$rules = [
    'custom_field' => ['required', new CustomRule],
];
