首先看SiteController.php

以下是必须引入的

use frontend\models\SiteLoginForm;
use frontend\models\User;
use frontend\models\SignupForm;

public function actionSignup()
{
    $model = new SignupForm();
    if ($model->load(Yii::$app->request->post())) {
        if ($user = $model->signup()) {
           // $login = new SiteLoginForm();             
            if(Yii::$app->getUser()->login($user)) {
                return $this->goHome();
            }
            else
            {
                var_dump($user);
            }
        }
    }

    return $this->render('signup', [
        'model' => $model,
    ]);
}
public function actionLogin()
{
    if (!\Yii::$app->user->isGuest) {
        return $this->goHome();
    }

    $model = new SiteLoginForm();
    if ($model->load(Yii::$app->request->post()) && $model->login()) {
        return $this->goBack();
    } else {
        return $this->render('login', [
            'model' => $model,
        ]);
    }
}

frontend/models/User.php文件

config/main.php代码

'components' => [
    'user' => [
        'identityClass' => 'frontend\models\User',
        'enableAutoLogin' => true,
    ],
],

SignupForm.php代码

//注意这里的规则由你自己定义有几个地段哈
public function rules()
{
     return [
        ['username', 'filter', 'filter' => 'trim'],
        ['username', 'required','message' => '用户名不能为空'],
        ['username', 'unique', 'targetClass' => '\frontend\models\User', 'message' => '用户名已存在'],
        ['username', 'string', 'min' => 2, 'max' => 255],
    

        ['password', 'required','message' => '密码不能为空'],
        ['password', 'string', 'min' => 6],
    ];
}

//注意这个方法里user表的字段
public function signup()
{
    if ($this->validate()) {
        $user = new User();
        $user->username = $this->username;            
        $user->setPassword($this->password);
        $user->create_time = time();            
        if ($user->save()) {
            return $user;
        }
    }

    return null;
}
