yii中的登录如何实现

yii中的登录如何实现

1、创建数据表shop_admin

CREATE TABLE `shop_admin` (
 `adminid` int(10) UNSIGNED NOT NULL COMMENT '主键ID',
 `adminuser` varchar(32) NOT NULL DEFAULT '' COMMENT '管理员账号',
 `adminpass` char(32) NOT NULL DEFAULT '' COMMENT '管理员密码',
 `adminemail` varchar(50) NOT NULL DEFAULT '' COMMENT '管理员邮箱',
 `logintime` int(10) UNSIGNED NOT NULL DEFAULT '0' COMMENT '登陆时间',
 `loginip` bigint(20) NOT NULL DEFAULT '0' COMMENT '登陆IP',
 `createtime` int(10) UNSIGNED NOT NULL DEFAULT '0' COMMENT '创建时间'
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

2、登陆页面

<?php
use yiiootstrapActiveForm;
use yiihelpersHtml;
$form = ActiveForm::begin([
 'id' => 'abc-form',
 'options' => ['class' => 'form-horizontal'],
])?>
<?= $form->field($model, 'adminuser')->textInput(['placeholder' => "用户名"])->label('账号') ?>
<?= $form->field($model, 'adminpass')->passwordInput()->label('密码') ?>
<?= Html::submitButton('提交') ?>
<?php ActiveForm::end() ?>

3、控制器

相关文章教程推荐：yii教程

<?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) {
// 获得post提交参数
 $post = Yii::$app->request->post();
 if($model->login($post)){
 return "登陆成功";
 } else {
 return "登陆失败";
 }
 } 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'],
// 验证密码是否正确
 ['adminpass', 'validatePass']
 ];
 }
 
 public function validatePass()
 {
 if (!$this->hasErrors()) {
// 判断用户名密码是否正确
 $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()) {
// 登陆信息写入session
 $session = Yii::$app->session;
 $session->open();
 $session->set('adminuser', $this->adminuser);
// 更新登陆时间和IP
 $this->updateAll(['logintime' => time(), 'loginip' => ip2long(Yii::$app->request->userIP)], ['adminuser' => $this->adminuser]);
 return true;
 }
 return false;
 }
}
