如何在 Laravel 中配对两个 arrays 输入验证？

Question

我有一个带有规则的表单请求

return [
    'brand_id' => ['required', 'integer'],
    'color_id' => ['required', 'integer'],
    'name' => ['required', 'max:255', 'string'],
    'capital' => ['required', 'string'],
    'price' => ['required', 'string'],
    'size' => ['required', 'string', 'max:255'],
    'incoming.*' => ['required', 'integer', 'gte:outgoing.0'],
];

我想通过它的每个索引来配对验证，可以在 Laravel 中做到这一点吗？

我结束了这种方式

foreach ($this->incoming as $key => $value) {
    $incoming["incoming.{$key}"] = ['required', 'integer', "gte:outgoing.{$key}"];
}

return array_merge([
    'brand_id' => ['required', 'integer'],
    'color_id' => ['required', 'integer'],
    'name' => ['required', 'max:255', 'string'],
    'capital' => ['required', 'string'],
    'price' => ['required', 'string'],
    'size' => ['required', 'string', 'max:255'],
], $incoming);

我会建议更优雅的方式：

return array_merge(
  [
    'brand_id' => ['required', 'integer'],
    'color_id' => ['required', 'integer'],
    'name' => ['required', 'max:255', 'string'],
    'capital' => ['required', 'string'],
    'price' => ['required', 'string'],
    'size' => ['required', 'string', 'max:255'],
  ],
  ...array_map(
    fn ($key) => ["incoming.{$key}" => ['required', 'integer', "gte:outgoing.{$key}"]],
    array_keys($this->incoming),
  )
);
