class CI_Email_Tutorial extends CI_Controller {
public function __construct() {
parent::__construct();
$this->load->helper('form');
$this->load->library('form_validation');
$this->load->library('encrypt');
}
// Show email page
public function index() {
$this->load->view('view_form');
}
// Send Gmail to another user
public function Send_Mail() {
// Check for validation
$this->form_validation->set_rules('user_email', 'User Email', 'trim|required|xss_clean');
$this->form_validation->set_rules('user_password', 'User Password', 'trim|required|xss_clean');
$this->form_validation->set_rules('to_email', 'To', 'trim|required|xss_clean');
$this->form_validation->set_rules('subject', 'Subject', 'trim|required|xss_clean');
$this->form_validation->set_rules('message', 'Message', 'trim|required|xss_clean');
if ($this->form_validation->run() == FALSE) {
$this->load->view('view_form');
} else {
// Storing submitted values
$sender_email = $this->input->post('user_email');
$user_password = $this->input->post('user_password');
$receiver_email = $this->input->post('to_email');
$username = $this->input->post('name');
$subject = $this->input->post('subject');
$message = $this->input->post('message');
// Configure email library
$config['protocol'] = 'smtp';
$config['smtp_host'] = 'ssl://smtp.googlemail.com';
$config['smtp_port'] = 465;
$config['smtp_user'] = $sender_email;
$config['smtp_pass'] = $user_password;
// Load email library and passing configured values to email library
$this->load->library('email', $config);
$this->email->set_newline("\r\n");
// Sender email address
$this->email->from('pkrock00@gmail.com', $username);
// Receiver email address
$this->email->to($receiver_email);
// Subject of email

if ($this->email->send()) {
$data['message_display'] = 'Email Successfully Send !';
