PHP Yii：数据库在运行时连接(PHP Yii: Database connect in runtime)

PHP Yii：数据库在运行时连接(PHP Yii: Database connect in runtime)

我想在运行时使用Yii连接到第二个数据库。 用户登录后，数据库名称将来自数据库表。

我在教程中看到我应该这样做：

$db2 = Yii::createComponent(array( 'class' => 'EMongoClient', 'server' => 'mongodb://127.0.0.1:27017', 'db' => $emp['database'] )); Yii::app()->setComponent('db2',$db2);

但在我的控制器中，当我访问Yii::app()->db2得到错误：

未定义属性“CWebApplication.db2”

我究竟做错了什么？

I would like to connect to a second database with Yii at runtime. The database name would come from a database table after the user to login.

I saw in a tutorial I should do this:

$db2 = Yii::createComponent(array( 'class' => 'EMongoClient', 'server' => 'mongodb://127.0.0.1:27017', 'db' => $emp['database'] )); Yii::app()->setComponent('db2',$db2);

But in my controler when I access Yii::app()->db2 get the error:

Property "CWebApplication.db2" is not defined

What am I doing wrong?

最满意答案

以下为我工作：

Yii::app()->mongodb->setActive(false); Yii::app()->mongodb->setServer('mongodb://localhost:27017'); Yii::app()->mongodb->setDb('db1'); Yii::app()->mongodb->setActive(true);

The following works for me:

Yii::app()->mongodb->setActive(false); Yii::app()->mongodb->setServer('mongodb://localhost:27017'); Yii::app()->mongodb->setDb('db1'); Yii::app()->mongodb->setActive(true);
