Yii2自带的注册可以作为网站的注册功能,但添加重复密码和验证码会更加完美!
问题:
-
用户名没有做严格的限制,类似“111”,“123456”,“_____111”这样的的用户名都是被允许的,那么如何限制用户输入我们所希望的用户名呢?
-
一般的注册,都有重复输入密码的input框,是为了让用户再次确认自己输入的密码,如何添加呢?
-
为了提高注册用户的质量,防止批量注册,添加验证码是不错的选择,如何加?
如何在不修改逻辑代码的情况下完美解决以上三个问题?看了下面的教程,一目了然!
以高级版2.0.6为例,打开/frontend/models/SignupForm.php
class SignupForm extends Model { public $username; public $email; public $password; /** * @inheritdoc */ public function rules() { return [ ['username', 'filter', 'filter' => 'trim'], ['username', 'required'], ['username', 'unique', 'targetClass' => 'commonmodelsUser', 'message' => 'This username has already been taken.'], ['username', 'string', 'min' => 2, 'max' => 255], ['email', 'filter', 'filter' => 'trim'], ['email', 'required'], ['email', 'email'], ['email', 'string', 'max' => 255], ['email', 'unique', 'targetClass' => 'commonmodelsUser', 'message' => 'This email address has already been taken.'], ['password', 'required'], ['password', 'string', 'min' => 6], ]; }
只需修改rules规则即可完美实现
a.添加用户字符限制,6-16位
['username', 'string', 'min' => 6, 'max' => 16],
输入限制:用户名由字母,汉字,数字,下划线组成,且不能以数字和下划线开头。
['username', 'match','pattern'=>'/^[(x{4E00}-x{9FA5})a-zA-Z]+[(x{4E00}-x{9FA5})a-zA-Z_d]*$/u','message'=>'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。'],
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
[['password','repassword'], 'required'], [['password','repassword'], 'string', 'min' => 6], ['repassword', 'compare', 'compareAttribute' => 'password','message'=>'两次输入的密码不一致!'],
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
['verifyCode', 'captcha'],
注意:需要在对应的控制器中添加以下代码,本例为SiteController中添加
public function actions() { return [ 'captcha' => [ 'class' => 'yiicaptchaCaptchaAction', 'fixedVerifyCode' => YII_ENV_TEST ? 'testme' : null, ], ]; }
修改之后的规则
class SignupForm extends Model { public $username; public $email; public $password; public $repassword; public $verifyCode; public function rules() { return [ ['username', 'filter', 'filter' => 'trim'], ['username', 'required'], ['username', 'unique', 'targetClass' => 'commonmodelsUser', 'message' => '该用户名已被使用!'], ['username', 'string', 'min' => 6, 'max' => 16], ['username', 'match','pattern'=>'/^[(x{4E00}-x{9FA5})a-zA-Z]+[(x{4E00}-x{9FA5})a-zA-Z_d]*$/u','message'=>'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。'], ['email', 'filter', 'filter' => 'trim'], ['email', 'required'], ['email', 'email'], ['email', 'string', 'max' => 255], ['email', 'unique', 'targetClass' => 'commonmodelsUser', 'message' => '该邮箱已经被注册!'], [['password','repassword'], 'required'], [['password','repassword'], 'string', 'min' => 6], ['repassword', 'compare', 'compareAttribute' => 'password','message'=>'两次输入的密码不一致!'], ['verifyCode', 'captcha'], ]; } ....
