Thanks for the reply David,
I found the solution, this is the code I'm using:
$crud->callback_before_delete(array($this, 'send_mail'));
function send_mail ($primary_key)
{
$query= mysql_query("SELECT * FROM table ORDER BY id DESC LIMIT 1");
$result= mysql_fetch_array($query);
$variable= $result['variable'];
$config['wordwrap']= TRUE;
$config['mailtype']= 'html';
$config['charset']= 'utf-8';
$config['crlf']= "\r\n";
$config['newline']= "\r\n";
$Eliminado= date('Y-m-d H:i:s');
$this->load->library('email');
$this->email->initialize($config);
$this->email->from('mail@sendmail.com','example');
$this->email->to('mimail@sendmail.com');
$this->email->cc('othermail@sendmail.com');
$this->email->subject('Registro eliminado en el Sistema ');
$this->email->message("Estimado ".$variable." se ha eliminado la información de un usuario en su plataforma. Fecha de Modificación:".$Eliminado."");
$this->email->send();
echo $this->email->print_debugger();
}
Regards.
