我如何使alpha_dash工作阿拉伯字母？ [英] How can I make alpha_dash work for Arabic alphabets?

问题描述

我要为阿拉伯字段添加规则，以确保它只包含字符或数字。

I want to add rule for Arabic fields to ensure that it contains only characters or number.

alpha_dash 仅适用于英文字母，我如何才能支援阿拉伯语？

alpha_dash only works with English alphabets, how can I make it support Arabic?

推荐答案

Alpha dash不是标准的php函数。

Alpha dash is not a standard php function.

function alpha_dash($str)
{
   return ( ! preg_match("/^([-a-z0-9_-])+$/i", $str)) ? FALSE : TRUE;
}

这应该匹配阿拉伯字母，数字，下划线和减号。 p>

This should match arabic letters, numbers, underscores and the minus sign.

function alpha_dash($str)
{
   return ( ! preg_match("/^[\-_ \d\p{Arabic}]*\p{Arabic}[\d\p{Arabic}]*$/ui", $str)) ? FALSE : TRUE;
} 

编辑：我可能搞错了正则表达式，

edit: I might have messed up the regex, but now at least you have something to go on.
