Laravel 验证检查数组大小最小值和最大值

有点晚了：

return [
    "ticket_photo" => ["required","array","min:2","max:4"], // validate an array contains minimum 2 elements and maximum 4 
    "ticket_photo.*" => ["required","mimes:jpeg,jpg,png,gif"], // and each element must be a jpeg or jpg or png or gif file 
];

拉拉维尔 5.6

您可以使用 ..https://laravel.com/docs/5.2/validation#rule-betweenbetween

例如：

'users' => 'required|array|between:2,4'

它在文档中没有明确说明，但它适用于数组，就像.size
