yii2怎么自适应切换模板

1、创建behavior

// frontend/behaviors/MobileBehavior.php
class MobileBehavior extends yiiaseBehavior{ public function events()
 { return [
 yiiwebController::EVENT_BEFORE_ACTION => 'beforeAction'
 ];
 } public function beforeAction($event)
 { if (strpos($_SERVER['HTTP_USER_AGENT'], 'iPhone') || strpos($_SERVER['HTTP_USER_AGENT'], 'Android') {
 $event->sender->module->setViewPath($event->sender->module->getBasePath().DIRECTORY_SEPARATOR.'H5Views');
 } 
 }
}

2、建一个基类BaseController.php（免费学习教程分享：php教程）

/ frontend/controllers/BaseController.php
class BaseController extends yiiwebController{ public function behaviors()
 { return [
 frontendehaviorsMobileBehavior::className()
 ];
 } // 其他action}

其他控制器继承BaseController。
3、在frontend下面创建H5Views, H5模板文件放在这里面就可以了。
