除非验证程序，否则无法使用必需的

Question

在我的应用程序中，我试图使用required_excess验证器，但每次我碰到控制器时都会抛出错误；

Method IlluminateValidationValidator::validateRequiredUnless,meta.app,pos does not exist.

这就是轨迹：

这是我的验证码：

$rules = [
"client" => "required_unless,meta.app,pos",
"customer" => "required",
"customer.fullname" => "required|min:4",
"customer.phone" => "required|numeric",
"customer.email" => "email|required_unless,meta.app,pos",
"payment" => "required",
"payment.type" => "required",
"items" => "required",
"items.*.id" => "required",
"items.*.quantity" => "required_if:meta.type,==,event|numeric",
"items.*.seat" => "required_if:meta.type,==,food",
"meta" => "required",
"meta.type" => "required",
"meta.timestamp" => "required",
"meta.token" => "required_unless,meta.app,pos"
];
$validator = Validator::make($request->all(), $rules, []);
// Validate incoming request
if ($validator->fails()) {
return response($validator->errors(), 400);
}

Answer 1

在required_unless之后应该是:而不是,。

required_unless:anotherfield,value,

尝试required_unless:meta.app,pos
