Laravel验证检查数组大小最小值和最大值

Question

我只需要在Laravel验证中检查一个数组包含最少2个值和最多4个值.是否可以使用默认验证规则？在size为完全一致的尺寸元支票和其他规则喜欢min和max是字符串,数字和文件大小.

Answer 1

你可以用between.. https://laravel.com/docs/5.2/validation#rule-between

例如:

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

它没有在文档中明确说明,但它适用于数组,就像size.

Answer 2

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 
];
