如何在yii2中使用自定义扩展/小部件？

Question

I use gii to generate a extension in yii2.0, here is the code

namespace ms\editor;

/**
 * This is just an example.
 */
class AutoloadExample extends \yii\base\Widget
{
    public function run()
    {
        return "Hello!";
    }
}

when I want to use it in my view file,

use ms\editor\AutoloadExample;
...
<?= AutoloadExample::widget();?>

I use yii2 baisic template, and I put the "ms" folder in "vendor" folder, but it just tell me class ms\editor\AutoloadExample not found, what should I to make yii2 to find the class?is there something like "components"or "extension" folder in yii1.1? can you help me?

Answer 1

Your widget should inherit the CWidget class and place the widget in components.

public class AutoloadExample extends CWidget 
{
   public function run() { }
}

You can then run the widget in your view like this;

$this->widget('application.components.AutoloadExample', array('your variables'));
