Laravel规则与问题正则表达式(OR)运算符 [英] Issue with Laravel Rules & Regex (OR) operator

问题描述

我的Laravel规则和正则表达式操作有一个小问题:

I'm having a small issue with my Laravel rules and regex operation :

基本上，规则是这样的数组:

Basically a rule is an array as such :

'room'=>'required|alpha_num|min:2|max:10',

我遇到的问题是使用正则表达式和|时. (或)运算符，例如:

The problem i'm having is when using regex and the | (or) operator such as :

'cid'=>'required|regex:/^((comp)|(soen)|(engr)|(elec))\d{3}$/i',

我收到服务器错误消息:

I'm getting a server error saying :

ErrorException

preg_match(): No ending delimiter '/' found

我猜想preg_match在/.../内部的第一个|处停止.

I'm guessing the preg_match is stopping at the first | inside the /.../.

反正还有编写上面的代码来使其工作吗?

Is there anyway to write the above code to make it work ?

完整代码:

public static $rules = array(

'cid' => array('required', 'regex:/^((comp)|(soen)|(engr)|(elec))\d{3}$/i'),

'description'=>'required|regex:/^[A-Za-z \t]*$/i|min:3|unique:courses',

'credits'=>'required|regex:/^\d+(\.\d)?$/'

);

推荐答案

http://laravel. com/docs/validation#rule-regex

regex:pattern

regex:pattern

正在验证的字段必须与给定的正则表达式匹配.

The field under validation must match the given regular expression.

注意:使用正则表达式模式时，可能需要在数组中指定规则而不是使用管道定界符，尤其是在正则表达式包含管道字符的情况下.

Note: When using the regex pattern, it may be necessary to specify rules in an array instead >of using pipe delimiters, especially if the regular expression contains a pipe character.

要澄清: 你会做这样的事情

To clarify: You would do something like this

$rules = array('test' => array('size:5', 'regex:foo'));
