Codeigniter联系表单提交返回超时

Question

您好我想知道是否有人可以让我深入了解为什么我的Codeigniter联系表格会提交时间？

我知道这是一个初学者错误，但我觉得这是我完全忽视的事情。我提供了控制器和视图。

我在Config文件中也设置了email.php，并加载了各种帮助程序和库。提前谢谢！

控制器

<?php
class contactform extends CI_Controller
{
    public function __construct()
    {
        parent::__construct();
        $this->load->helper(array('form','url'));
        $this->load->library(array('session', 'form_validation', 'email'));
    }

    function index()
    {
        //set validation rules
        $this->form_validation->set_rules('name', 'Name', 'trim|required|xss_clean|callback_alpha_space_only');
        $this->form_validation->set_rules('email', 'Emaid ID', 'trim|required|valid_email');
        $this->form_validation->set_rules('subject', 'Subject', 'trim|required|xss_clean');
        $this->form_validation->set_rules('message', 'Message', 'trim|required|xss_clean');

        //run validation on form input
        if ($this->form_validation->run() == FALSE) {
            //validation fails
            $this->load->view('contact_form_view');
        } else {
            //get the form data
            $name       = $this->input->post('name');
            $from_email = $this->input->post('email');
            $subject    = $this->input->post('subject');
            $message    = $this->input->post('message');

            //set to_email id to receive emails
            $to_email = 'littleliongirldesigns@gmail.com';

            //configure email settings
            $config['protocol']  = 'smtp';
            $config['smtp_host'] = 'ssl://smtp.gmail.com';
            $config['smtp_port'] = '465';
            $config['smtp_user'] = 'email';
            $config['smtp_pass'] = 'password';
            $config['mailtype']  = 'html';
            $config['charset']   = 'iso-8859-1';
            $config['wordwrap']  = TRUE;
            $config['newline']   = "\r\n"; //use double quotes
            $this->load->library('email', $config);
            $this->email->initialize($config);                        

            //send mail
            $this->email->from($from_email, $name);
            $this->email->to($to_email);
            $this->email->subject($subject);
            $this->email->message($message);

            if ($this->email->send()) {
                // mail sent
                $this->session->set_flashdata('msg','<div class="alert alert-success text-center">Your mail has been sent successfully!</div>');
                redirect('contactform/index');
            } else {
                //error
                $this->session->set_flashdata('msg','<div class="alert alert-danger text-center">There is error in sending mail! Please try again later</div>');
                redirect('contactform/index');
            }
        }
    }

    //custom validation function to accept only alphabets and space input
    function alpha_space_only($str)
    {
        if (!preg_match("/^[a-zA-Z ]+$/",$str)) {
            $this->form_validation->set_message('alpha_space_only', 'The %s field must contain only alphabets and space');
            return FALSE;
        } else {
            return TRUE;
        }
    }
}
?>
