【问题描述】：

我在codeigniter中创建了一个注册页面，一切都很好，但是当我点击注册时，它会将所有数据插入数据库，但是它不会向邮件发送确认信并给出错误：

遇到以下 SMTP 错误：99 无法分配请求 地址无法使用 php SMTP 发送电子邮件。您的服务器可能不是 配置为使用此方法发送邮件。

这是我的控制器：

<?php
class User extends CI_Controller

    public function __construct()
    
        parent::__construct();
        $this->load->helper(array('form','url', 'security'));
        $this->load->library(array('session', 'form_validation', 'email'));
        $this->load->database();
        $this->load->model('User_model');
    

    function index()
    
        $this->register();
    



    function register()
    
        //set validation rules
        $this->form_validation->set_rules('username', 'Username', 'trim|required|alpha|min_length[3]|max_length[30]|is_unique[instructors.instructors_slug]xss_clean');
        $this->form_validation->set_rules('mail', 'Email', 'trim|required|valid_email|is_unique[instructors.mail]');
        $this->form_validation->set_rules('password', 'password', 'trim|required|md5');
        $this->form_validation->set_rules('password2', 'Confirm Password', 'trim|required|md5|matches[password]');
        $to_email= $this->input->post('mail');

        $data['courses'] = $this->Popular_courses_model->get_popular_courses();
        $data['news'] = $this->News_model->get_news();


        //validate form input
        if ($this->form_validation->run() == FALSE)
        
            // fails


            $this->load->view('templates/header');
            $this->load->view('pages/index', $data);
            $this->load->view('templates/footer');
        
        else
        
            //insert the user registration details into database
            $data = array(
                'instructors_slug' => $this->input->post('username'),
                'mail' => $to_email,
                'password' => $this->input->post('password')
            );

            // insert form data into database
            if ($this->User_model->insertUser($data)) 



                if ($this->User_model->sendEmail($to_email)) 
                    // successfully sent mail
                    $this->session->set_flashdata('msg','<div class="alert alert-success text-center">You are Successfully Registered! Please confirm the mail sent to your Email-ID!!!</div>');
                    redirect('user/register');
                
                else
                
                    // error
                    $this->session->set_flashdata('msg','<div class="alert alert-danger text-center">'.$to_email.'  gondermir '.$this->email->print_debugger().'</div>');
                    redirect('user/register');
                
            
            else
            
                // error
                $this->session->set_flashdata('msg','<div class="alert alert-danger text-center">daxil elemir</div>');
                    redirect('user/register');
            
        
    



    function verify($hash=NULL)
    
        if ($this->User_model->verifyEmailID($hash))
        
            $this->session->set_flashdata('verify_msg','<div class="alert alert-success text-center">Your Email Address is successfully verified! Please login to access your account!</div>');
            redirect('user/register');
        
        else
        
            $this->session->set_flashdata('verify_msg','<div class="alert alert-danger text-center">Sorry! There is error verifying your Email Address!</div>');
            redirect('user/register');
        
    

?>

这是我的模型：

<?php
class User_model extends CI_Model

    function __construct()
    
        // Call the Model constructor
        parent::__construct();
    

    //insert into user table
    function insertUser($data)
    
        return $this->db->insert('instructors', $data);
    


    //send verification email to user's email id
    function sendEmail($to_email)
    
        $from_email = '[e-mail]'; //change this to yours
        $subject = 'Verify Your Email Address';
        $message = 'Dear User,<br /><br />Please click on the below activation link to verify your email address.<br /><br /> http://www.wtf.az/user/verify/' . md5($to_email) . '<br /><br /><br />Thanks<br />Mydomain Team';

        //configure email settings
        $config['protocol'] = 'smtp';
        $config['smtp_host'] = 'ssl://smtp.gmail.com'; //change this
        $config['smtp_port'] = '465';
        $config['smtp_user'] = '[e-mail]'; //change this
        $config['smtp_pass'] = 'mypass'; //change this
        $config['mailtype'] = 'html';
        $config['charset'] = 'utf-8';
        $config['wordwrap'] = TRUE;
        $config['newline'] = "\r\n";
        $this->email->initialize($config);

        //send mail
        $this->load->library('email');
        $this->email->from($from_email, 'WTF');
        $this->email->to($to_email);
        $this->email->subject($subject);
        $this->email->message($message);
        return $this->email->send();
    

    //activate user account
    function verifyEmailID($key)
    
        $data = array('status' => 1);
        $this->db->where('md5(mail)', $key);
        return $this->db->update('instructors', $data);
    

?>

【问题讨论】：

我的直觉是它无法绑定到发送邮件的端口。您应该只使用PHP 创建一个minimal reproducible example，看看是否得到相同的结果。您还应该使用操作系统和网络服务器更新您的问题。

【参考方案1】：

尝试在您的 User_model 中更改此代码

$config['protocol'] = 'smtp';

到

$config['protocol'] = 'mail';
