Activities

Activity instances are created for special events in the context of a humhub\modules\content\models\ContentContainer|ContentContainer like the creation of content.

Contrary to notifications - activities are always bound to a humhub\modules\content\models\ContentContainer|ContentContainer, and are not targeted for specific users. Besides the relation to the ContentContainer - an activity can also be assigned with a Content or ContentAddon and automatically inherits some content properties such as visibility.

Similar to notifications activities can be related to an originator user and a source object. The activity will adopt some properties as the visibility in cas of Content or ContentAddon sources.

Implement a Custom Activity

Create Class & View

Your custom activites should reside in your modules activities directory.

Example activity:

<?php

namespace johndoe\example\activities;

use humhub\core\activity\components\BaseActivity;

class SomethingHappend extends BaseActivity
{
    // View Name for activity
    public $viewName = "somethingHappend";

    // Module Id (required)
    public $moduleId = "example";
}
?>

By default activity views should be located inside a activities/views directory (e.g. mymodule/activities/views/).

Example view file somethingHappend.php:

<?php

use yii\helpers\Html;

echo Yii::t('ExampleModule.views_notifications_newLike', "%someUser% did something cool.", array(
    '%someUser%' => '<strong>' . Html::encode($originator->displayName) . '</strong>'
));
?>

If you require a different view for mails, you have to add a view with the same view name to the activities/views/mail directory.

Activity creation

SomethingHappend::instance()->from($user)->about($this)->create();
