yii中的登錄如何實現

1、創建數據表shop_admin

CREATE TABLE `shop_admin` (   `adminid` int(10) UNSIGNED NOT NULL COMMENT '主鍵ID',   `adminuser` varchar(32) NOT NULL DEFAULT '' COMMENT '管理員賬號',   `adminpass` char(32) NOT NULL DEFAULT '' COMMENT '管理員密碼',   `adminemail` varchar(50) NOT NULL DEFAULT '' COMMENT '管理員郵箱',   `logintime` int(10) UNSIGNED NOT NULL DEFAULT '0' COMMENT '登陸時間',   `loginip` bigint(20) NOT NULL DEFAULT '0' COMMENT '登陸IP',   `createtime` int(10) UNSIGNED NOT NULL DEFAULT '0' COMMENT '創建時間' ) ENGINE=InnoDB DEFAULT CHARSET=utf8;

2、登陸頁面

<?php use yiibootstrapActiveForm; use yiihelpersHtml; $form = ActiveForm::begin([     'id' => 'abc-form',     'options' => ['class' => 'form-horizontal'], ])?> <?= $form->field($model, 'adminuser')->textInput(['placeholder' => "用戶名"])->label('賬號') ?> <?= $form->field($model, 'adminpass')->passwordInput()->label('密碼') ?> <?= Html::submitButton('提交') ?> <?php ActiveForm::end() ?>

3、控制器

<?php namespace appcontrollers; use yiiwebController; use appmodelsAdmin; use Yii;   class IndexController extends Controller {     public function actionIndex()     { //      不使用布局         $this->layout = false;         $model = new Admin; //        是否是post提交         if (Yii::$app->request->isPost) { //            獲得post提交參數             $post = Yii::$app->request->post();             if($model->login($post)){                 return "登陸成功";             } else {                 return "登陸失敗";             }         } else {             return $this->render("index", ['model' => $model]);         }     }   }

4、模型

<?php namespace appmodels; use yiidbActiveRecord; use Yii; class Admin extends ActiveRecord {     public static function tableName()     {         return "{{%admin}}";     }       public function rules()     {         return [             ['adminuser', 'required'],             ['adminpass', 'required'], //           驗證密碼是否正確             ['adminpass', 'validatePass']         ];     }       public function validatePass()     {         if (!$this->hasErrors()) { //            判斷用戶名密碼是否正確             $data = self::find()                 ->where(['adminuser' => $this->adminuser])                 ->andwhere(['adminpass' => md5($this->adminpass)])                 ->one();             if (is_null($data)) {                 $this->addError('adminpass', 'adminuser or adminpass error');             }         }     }     public function login($data)     {         if($this->load($data) && $this->validate()) { //            登陸信息寫入session             $session = Yii::$app->session;             $session->open();             $session->set('adminuser', $this->adminuser); //           更新登陸時間和IP             $this->updateAll(['logintime' => time(), 'loginip' => ip2long(Yii::$app->request->userIP)], ['adminuser' => $this->adminuser]);             return true;         }         return false;     } }
