Laravel 验证十进制 0-99.99 [英] Laravel validate decimal 0-99.99

问题描述

Laravel 没有对 decimal 的验证，所以我需要一个 regex 或其他验证方法来验证 0 - 99.99

Laravel does not have a validation for decimal, so I need a regex or other validation method to validate a numeric value of 0 - 99.99

我试过了

required|regex:^d{0,2}(.d{1,2})?$/
required|regex:[1-9]d?(.dd?)?|0.[1-9]d?||0.0[1-9]
required|regex:/[1-9]d?(.dd?)?|0.[1-9]d?||0.0[1-9]/
required|regex:/[d]{2}.[d]{2}/
required|regex:/[d]{0-2}.[d]{0,2}/

我在尝试输入 0.05 或 preg_match 的未知修饰符时遇到无效格式"

I am either getting "invalid format" when trying to enter 0.05 or unknown modifiers for preg_match

对于在 laravel 中验证小数所需的 regex 的任何帮助表示赞赏(在小数点之前或之后提供可选值

any help with the regex needed to validate a decimal in laravel is appreciated (with optional values before or after decimal

推荐答案

Laravel between 验证规则实际上非常强大，也可以处理十进制值.因此无需使用正则表达式，只需执行以下操作:

The Laravel between validation rule is actually pretty powerful and can handle decimal values as well. So there's no need to use regex just do this:

'required|between:0,99.99'
