before_delete_post

HI,
I have an event calendar plugin but there is no mailing possibility.

What I want is:

sending some mails after deleting an event in the admin panel.

I have a plugin with this code but the hook is never fired!

function verstuur_mail( $pid )
//——————————
{
$to = ‘[email protected]’;
$subject = ‘afspraak’;
$headers = array(‘Content-Type: text/html; charset=UTF-8’);
$html = ‘<b>test</b><br>alles ok<br><br>Alex’;

wp_mail( $to, $subject, $html, $headers);

return $pid;
}

add_action( ‘before_delete_post’, ‘verstuur_mail’ );

Can anyone help me with this issue.

Thx, Luc
