这是我的代码：

this->load->library('email');       
    $config['mailtype'] = 'html';
    $config['wordwrap'] = TRUE;
    $this->email->initialize($config);
        $this->email->from('<email>','Alega');
        $this->email->to('<email>'); 
        $this->email->subject('Email Test');
        $this->email->message('<iframe title="YouTube video player" width="480" height="390" src="<url>" frameborder="0" allowfullscreen></iframe>');   

            $this->email->send();
