定义是MyController.php<?phpnamespaceappcomponents;useyiibaseWidget;useyiihelpersHtml;classHelloWidgetextendsWidget{{代码...}}然后调用是在view中<?phpuseappcomponentsHelloWidget;...
//定义是MyController.php
namespace appcomponents;
use yiibaseWidget;
use yiihelpersHtml;
class HelloWidget extends Widget
{
public $message;
public function init()
{
parent::init();
if ($this->message === null) {
$this->message = 'Hello World';
}
}
public function run()
{
return Html::encode($this->message);
}
}
//然后调用是在view中
use appcomponentsHelloWidget;
?>
= HelloWidget::widget(['message' => 'Good morning']) ?>
//结果报错找不到组件
Class 'appcomponentsHelloWidget' not found
请问我定义是不是错了呀?
回复内容:
//定义是MyController.php
namespace appcomponents;
use yiibaseWidget;
use yiihelpersHtml;
class HelloWidget extends Widget
{
public $message;
public function init()
{
parent::init();
if ($this->message === null) {
$this->message = 'Hello World';
}
}
public function run()
{
return Html::encode($this->message);
}
}
//然后调用是在view中
use appcomponentsHelloWidget;
?>
= HelloWidget::widget(['message' => 'Good morning']) ?>
//结果报错找不到组件
Class 'appcomponentsHelloWidget' not found

命名空间的问题
很少用app开始的明明空间,一般都是common/components;或者根据模块来,frontend backend
