Hooks for front end edits

[nsc]

Hi there,

Been working with ProcessWire for a while now and have just started having a play with Hooks.

I'm trying to generate an email when the page is updated from the front end, although I've only managed to get this to work when updating via the backend.

My code in finished.php

$this->addHookAfter('Page::changed', function(HookEvent $event) {
  $m = new WireMail();
	$m->to('email@email.com')
	  ->from('email@email.com')
	  ->subject('Page has been changed!')
	  ->body('Content')
	  ->send();
});

Can anyone help out or point me in the right direction?

Solved it by adding the code to init.php instead!
