Yii2自備的註冊可以作為網站的註冊功能，但添加重複密碼和驗證碼會更加完美！

問題：

用戶名沒有做嚴格的限制，類似“111”，“123456”，“_____111”這樣的用戶名都是被允許的，那麼如何限制用戶輸入我們所希望的用戶名呢？

一般的註冊，都有重複輸入密碼的input框，是為了讓使用者再次確認自己輸入的密碼，如何加入呢？

為了提高註冊用戶的質量，防止批量註冊，添加驗證碼是不錯的選擇，如何加？

如何在不修改邏輯程式碼的情況下完美解決以上三個問題？看了下面的教程，一目了然！

以高級版2.0.6為例，打開/frontend/models/SignupForm.php

,
            [&#39;username&#39;, &#39;required&#39;],
            [&#39;username&#39;, &#39;unique&#39;, &#39;targetClass&#39; => &#39;commonmodelsUser&#39;, &#39;message&#39; => &#39;This username has already been taken.&#39;],
            [&#39;username&#39;, &#39;string&#39;, &#39;min&#39; => 2, &#39;max&#39; => 255],

            [&#39;email&#39;, &#39;filter&#39;, &#39;filter&#39; => &#39;trim&#39;],
            [&#39;email&#39;, &#39;required&#39;],
            [&#39;email&#39;, &#39;email&#39;],
            [&#39;email&#39;, &#39;string&#39;, &#39;max&#39; => 255],
            [&#39;email&#39;, &#39;unique&#39;, &#39;targetClass&#39; => &#39;commonmodelsUser&#39;, &#39;message&#39; => &#39;This email address has already been taken.&#39;],

            [&#39;password&#39;, &#39;required&#39;],
            [&#39;password&#39;, &#39;string&#39;, &#39;min&#39; => 6],
        ];
    }

只需修改rules规则即可完美实现

a.添加用户字符限制,6-16位

[&#39;username&#39;, &#39;string&#39;, &#39;min&#39; => 6, &#39;max&#39; => 16],

输入限制：用户名由字母，汉字，数字，下划线组成，且不能以数字和下划线开头。

[&#39;username&#39;, &#39;match&#39;,&#39;pattern&#39;=>&#39;/^[(x{4E00}-x{9FA5})a-zA-Z]+[(x{4E00}-x{9FA5})a-zA-Z_d]*$/u&#39;,
&#39;message&#39;=>&#39;用户名由字母，汉字，数字，下划线组成，且不能以数字和下划线开头。&#39;],

b.添加重复密码字段

public $repassword;

  一般重复密码与密码的字段验证基本上是一致的，所以可以在password中添加repassword，并添加两次输入一致的限制

[[&#39;password&#39;,&#39;repassword&#39;], &#39;required&#39;],
[[&#39;password&#39;,&#39;repassword&#39;], &#39;string&#39;, &#39;min&#39; => 6],
[&#39;repassword&#39;, &#39;compare&#39;, &#39;compareAttribute&#39; => &#39;password&#39;,&#39;message&#39;=>&#39;两次输入的密码不一致！&#39;],

c.添加验证码字段

public $verifyCode;

  验证码有自带的扩展，只需添加以下代码即可

[&#39;verifyCode&#39;, &#39;captcha&#39;],

本例为SiteController中添加[/b]

    public function actions()
    {
        return [
            &#39;captcha&#39; => [
                &#39;class&#39; => &#39;yiicaptchaCaptchaAction&#39;,
                &#39;fixedVerifyCode&#39; => YII_ENV_TEST ? &#39;testme&#39; : null,
            ],
        ];
    }

修改之後的規則

class SignupForm extends Model
{
public $username;
public $email;
public $password;

public $repassword;
public $verifyCode;

public function rules()
{
return [
[&#39;username&#39;, &#39;filter&#39;, &#39;filter&#39; => &#39;trim&#39;],
[&#39;username&#39;, &#39;required&#39;],
[&#39;username&#39;, &#39;unique&#39;, &#39;targetClass&#39; => &#39;commonmodelsUser&#39;, &#39;message&#39; => &#39;该用户名已被使用！&#39;],
[&#39;username&#39;, &#39;string&#39;, &#39;min&#39; => 6, &#39;max&#39; => 16],
[&#39;username&#39;, &#39;match&#39;,&#39;pattern&#39;=>&#39;/^[(x{4E00}-x{9FA5})a-zA-Z]+[(x{4E00}-x{9FA5})a-zA-Z_d]*$/u&#39;,
&#39;message&#39;=>&#39;用户名由字母，汉字，数字，下划线组成，且不能以数字和下划线开头。&#39;],

[&#39;email&#39;, &#39;filter&#39;, &#39;filter&#39; => &#39;trim&#39;],
[&#39;email&#39;, &#39;required&#39;],
[&#39;email&#39;, &#39;email&#39;],
[&#39;email&#39;, &#39;string&#39;, &#39;max&#39; => 255],
[&#39;email&#39;, &#39;unique&#39;, &#39;targetClass&#39; => &#39;commonmodelsUser&#39;, &#39;message&#39; => &#39;该邮箱已经被注册！&#39;],

[[&#39;password&#39;,&#39;repassword&#39;], &#39;required&#39;],
[[&#39;password&#39;,&#39;repassword&#39;], &#39;string&#39;, &#39;min&#39; => 6],
[&#39;repassword&#39;, &#39;compare&#39;, &#39;compareAttribute&#39; => &#39;password&#39;,&#39;message&#39;=>&#39;两次输入的密码不一致！&#39;],

[&#39;verifyCode&#39;, &#39;captcha&#39;],
];
}
....
