cara mengirimkan detail transaksi pembelian produk ke email pembeli

Assalamualaikum,.. Pada script sebenarnya sudah ada pengiriman ke email,
namun mungkin tidak terkirim karena harus diubah ke smtp seperti pada pembahasan sebelumnya,
pada topic lupa password email yang tidak terkirim, sekarang tinggal diperbaiki/ubah menjadi smtp.
 
buka file : C:\xampp\htdocs\marketplace\application\controllers\Members.php
 
lalu cari baris : function selesai_belanja(){
 
lalu didalamnya cari script :
$this->email->from($iden['email'], $iden['nama_website']);
$this->email->to($email_tujuan);
$this->email->cc('');
$this->email->bcc('');
 
$this->email->subject($subject);
$this->email->message($message);
$this->email->set_mailtype("html");
$this->email->send();
 
$config['protocol'] = 'sendmail';
$config['mailpath'] = '/usr/sbin/sendmail';
$config['charset'] = 'utf-8';
$config['wordwrap'] = TRUE;
$config['mailtype'] = 'html';
$this->email->initialize($config);
 
ubah menjadi :
$this->load->library('email');
$config['protocol']    = 'smtp'; 
$config['smtp_host']    = 'ssl://smtp.googlemail.com';
$config['smtp_port']    = '465';
$config['smtp_timeout'] = '7';
$config['smtp_user']    = "xxxxxxxxx@gmail.com";
$config['smtp_pass']    = "xxxxxxxxxxxxxxx"; 
$config['charset']    = 'utf-8';
$config['newline']    = "\r\n";
$config['mailtype'] = 'html'; 
$config['validation'] = TRUE; 
$this->email->initialize($config);
$this->email->from("xxxxxxxxx@gmail.com", "$identitas[nama_website]");
$this->email->to($email);
$this->email->cc('');
$this->email->bcc('');
$this->email->subject($subject);
$this->email->message($message);
$this->email->send();
