Laravel max Validator not working
提问by randomor
I'm new to Laravel.
我是 Laravel 的新手。
Could someone explain why maxvalidator doesn't work as I expected in this case?
有人可以解释为什么max在这种情况下验证器不能按我预期的那样工作吗？
$input = ["schoolSeatsTotal" => '2000'];
$rules = ['schoolSeatsTotal'=>'max:300'];
$validator = Validator::make($input, $rules);
$validator->fails(); //Expected: true, Actual: false.
回答by Laurence
You have schoolSeatsTotalas a string. For string data, max value corresponds to the number of characters. You want to validate an integer instead.
你有schoolSeatsTotal一个字符串。对于字符串数据，最大值对应于字符数。您想要验证一个整数。
So change
所以改变
$input = ["schoolSeatsTotal" => '2000'];
to
到
$input = ["schoolSeatsTotal" => 2000];
To make sure you are validating numbers - do this:
为确保您正在验证数字 - 执行以下操作：
$rules = ['schoolSeatsTotal'=>'numeric|max:300'];
