验证前运行方法后的Laravel验证器

我在下面有验证规则

public function rules()
{
    return [
        'ports' => 'required|array|min:2|max:10',
        'ports.*.id' => 'required|distinct|exists:ports,id',
        'ports.*.order' => 'required|distinct|integer|between:1,10',
    ];
}

以及withValidator方法

public function withValidator($validator)
{
    // check does order numbers increasing consecutively
    $validator->after(function ($validator) {
        $orders = Arr::pluck($this->ports, 'order');
        sort($orders);

        foreach ($orders as $key => $order) {
            if ($key === 0) continue;

            if ($orders[$key - 1] + 1 != $order) {
                $validator->errors()->add(
                    "ports.$key.order",
                    __('validation.increase_consecutively', ['attribute' => __('validation.attributes.order')])
                );
            };
        }
    });
}

如果客户端没有发送

端口

数组，

Arr:pull

方法由于

$this->ports

等于

NULL

而引发异常。在formRequest中完成验证后，如何调用此代码块？

尝试写入

if ($validator->fails())
{
    // Handle errors
}

前

---

我想应该是

$validator->fails（）

，因为@akcoban希望在所有规则无误通过后，使用validator（$validator）运行公共函数

public function withValidator($validator)
{
  if ($validator->fails())
  {
    $orders = Arr::pluck($this->ports, 'order');
    sort($orders);

    foreach ($orders as $key => $order) {
       if ($key === 0) continue;

       if ($orders[$key - 1] + 1 != $order) {
           $validator->errors()->add(
               "ports.$key.order",
               __('validation.increase_consecutively', ['attribute' => __('validation.attributes.order')])
           );
       };
    }
  }
}
