一、新建Mysql数据库test,建立表:
CREATE TABLE `country` ( `code` CHAR(2) NOT NULL PRIMARY KEY, `name` CHAR(52) NOT NULL, `population` INT(11) NOT NULL DEFAULT '0' ) ENGINE=InnoDB DEFAULT CHARSET=utf8; INSERT INTO `country` VALUES ('AU','Australia',18886000); INSERT INTO `country` VALUES ('BR','Brazil',170115000); INSERT INTO `country` VALUES ('CA','Canada',1147000); INSERT INTO `country` VALUES ('CN','China',1277558000); INSERT INTO `country` VALUES ('DE','Germany',82164700); INSERT INTO `country` VALUES ('FR','France',59225700); INSERT INTO `country` VALUES ('GB','United Kingdom',59623400); INSERT INTO `country` VALUES ('IN','India',1013662000); INSERT INTO `country` VALUES ('RU','Russia',146934000); INSERT INTO `country` VALUES ('US','United States',278357000);
二、修改config/db.php中的数据库连接
'db' => [ 'class' => 'yii\db\Connection', 'dsn' => 'mysql:host=localhost;dbname=mydatabase', // MySQL, MariaDB //'dsn' => 'sqlite:/path/to/database/file', // SQLite //'dsn' => 'pgsql:host=localhost;port=5432;dbname=mydatabase', // PostgreSQL //'dsn' => 'cubrid:dbname=demodb;host=localhost;port=33000', // CUBRID //'dsn' => 'sqlsrv:Server=localhost;Database=mydatabase', // MS SQL Server, sqlsrv driver //'dsn' => 'dblib:host=localhost;dbname=mydatabase', // MS SQL Server, dblib driver //'dsn' => 'mssql:host=localhost;dbname=mydatabase', // MS SQL Server, mssql driver //'dsn' => 'oci:dbname=//localhost:1521/mydatabase', // Oracle 'username' => 'root', //数据库用户名 'password' => '', //数据库密码 'charset' => 'utf8', ],
三、新建models/Country.php:
<?php namespace app\models; use yii\db\ActiveRecord; class Country extends ActiveRecord { }
新建controllers/CountryController.php:
<?php namespace app\controllers; use yii\web\Controller; use yii\data\Pagination; use app\models\Country; class CountryController extends Controller { public function actionIndex() { $query = Country::find(); $pagination = new Pagination([ 'defaultPageSize' => 5, 'totalCount' => $query->count(), ]); $countries = $query->orderBy('name') ->offset($pagination->offset) ->limit($pagination->limit) ->all(); return $this->render('index', [ 'countries' => $countries, 'pagination' => $pagination, ]); } }
新建视图 views/country/index.php
<?php use yii\helpers\Html; use yii\widgets\LinkPager; ?> <h1>Countries</h1> <ul> <?php foreach ($countries as $country): ?> <li> <?= Html::encode("{$country->name} ({$country->code})") ?>: <?= $country->population ?> </li> <?php endforeach; ?> </ul> <?= LinkPager::widget(['pagination' => $pagination]) ?>
测试:http://test.com/index.php?r=country/index
查看结果并测试分页效果。
