laravel中动态输入字段的验证

use Illuminate\Support\Facades\Validator;
use Illuminate\Http\Request;

public function validateDynamicFields(Request $request)
{
    $rules = [
        'common_field' => 'required|string',
        'dynamic_field' => 'required_if:common_field,value1|string',
    ];

    $validator = Validator::make($request->all(), $rules);

    if ($validator->fails()) {
        // 验证失败，处理错误逻辑
        return response()->json(['error' => $validator->errors()], 400);
    }

    // 验证通过，继续处理其他逻辑
    // ...
}
