Detailed explanation of yii2.0 model rules verification

The registration that comes with Yii2 can be used as the registration function of the website, but adding repeated passwords and verification codes will be more perfect!

Question:

There are no strict restrictions on user names. User names such as "111", "123456", and "_____111" are all allowed. So how to restrict user input? What about our desired username?

General registration, there is an input box for re-entering the password, which is to allow the user to confirm the password he entered again. How to add it?

In order to improve the quality of registered users and prevent batch registration, adding a verification code is a good choice. How to add it?

How to perfectly solve the above three problems without modifying the logic code? After reading the tutorial below, it’s clear at a glance!

Take the advanced version 2.0.6 as an example, open /frontend/models/SignupForm.php

,
            ['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'],

本例为SiteController中添加[/b]

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

The modified rules

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'],
];
}
....
