Laravel验证检查数组大小的最小值和最大值 [英] Laravel Validation check array size min and max

问题描述

我只需要检查Laravel验证数组是否包含最小2个值和最大4个值.是否有任何默认的验证规则可用于此? size 元素检查是否完全匹配大小，而其他规则(例如 min 和 max )则用于字符串，数字和文件大小.

I just need to check in Laravel validation that an array contains minimum 2 values and maximum 4 values. Is there any default validation rule can be used for this ? The size element checks for exact size match and the other rules likes min and max are for strings, digits and file size.

推荐答案

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 
];
