我在网上看了关于 CRegularExpressionValidator 的解释，但我就是不明白.有人可以告诉我我应该做什么吗?或者甚至只是给我一个包含所有步骤的简单示例的链接

I need to validate that a username and password is in the right format. In my case 6-14 letters\digits or '*'. Since the rules may change I want to use something that is easy to maintain.
I have looked online on the explanation about CRegularExpressionValidator but I just don't get it. Can someone please tell me what exactly I should do? or even just give me a link to a simple example that cover all the steps

谢谢

推荐答案

您可以尝试使用 match (CRegularExpressionValidator) 规则来验证属性值与特定的正则表达式如:

You can try to use match (CRegularExpressionValidator) rule to validate the attribute value with the specific regular expression like:

public function rules() {
    return array(
        array('username, password', 'required'),
        array(
            'username, password',
            'match', 'pattern' => '/^[\*a-zA-Z0-9]{6,14}$/',
            'message' => 'Invalid characters in username or password.',
        ),
    );
}

注意:添加正则表达式作为'pattern'键的值.
