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，因此我需要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

我尝试过

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

尝试输入0.05时出现无效格式"或preg_match的未知修饰符

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

感谢对regex进行验证的regex所需的任何帮助(在小数点之前或之后有可选值

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，并且还可以处理十进制值.因此，无需使用正则表达式即可:

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'
