I think you have 2 possibilities:
foreach
Let's assume you have a function mail_users
within your UsersController
function mail_users($subject = 'Sample subject') {
$users = $this->User->find('all', array('fields' => array('email'));
foreach ($users as $user) {
$this->Email->reset();
$this->Email->from = '<[email protected]>';
$this->Email->to = $user['email'];
$this->Email->subject = $subject ;
$this->Email->sendAs = 'html';
$this->Email->send('Your message body');
}
}
In this function the $this->Email->reset()
is important.
using BCC
function mail_users($subject = 'Sample subject') {
$users = $this->User->find('all', array('fields' => array('email'));
$bcc = '';
foreach ($users as $user) {
$bcc .= $user['email'].',';
}
$this->Email->from = '<[email protected]>';
$this->Email->bcc = $bcc;
$this->Email->subject = $subject;
$this->Email->sendAs = 'html';
$this->Email->send('Your message body');
}
Now you can just call this method with a link to /users/mail_users/subject
For more information be sure to read the manual on the Email Component.
