## Trapping the publication event
|
|
|
|
Sometimes, you'll want to do something whenever a particular kind of page is published. This example sends an email
|
|
whenever a blog entry has been published.
|
|
|
|
:::php
|
|
class Page extends SiteTree {
|
|
// ...
|
|
function onAfterPublish() {
|
|
mail("sam@silverstripe.com", "Blog published", "The blog has been published");
|
|
parent::onAfterPublish();
|
|
}
|
|
}
