Laravel-使用正则表达式仅验证字母，数字和空格 [英] Laravel - Validate only letters, numbers and spaces using regex

问题描述

我正在尝试以这种方式验证由字母，数字和空格组成的字段:

I am trying to validate a field made ​​up of letters, numbers and spaces in this way:

$rules = array(
    'field'=> 'regex:/([A-Za-z0-9 ])+/'
);

但是如果我尝试插入''和其他字符，验证仍然必须成功.

but if I try to insert characters like ' " and others, the validation still has to be successful.

我的正则表达式怎么了?

What's wrong 'in my regular expression?

推荐答案

$rules = array(
    'field'=> 'regex:/(^[A-Za-z0-9 ]+$)+/'
);
