发送电子邮件

要使用CodeIgniter发送电子邮件，首先必须使用以下方式加载电子邮件库 -

$this->load->library('email');

加载库之后，只需执行以下功能即可设置发送电子邮件所需的元素。在 从（） 函数用来设置-从正在发送的电子邮件，其中并 以（） 函数用于- 谁被发送的电子邮件。所述 主体（） 和 消息（） 函数是用来设置电子邮件的主题和消息。

$this->email->subject('Email Test');
$this->email->message('Testing the email class.');

之后，执行 send（） 函数，如下所示发送电子邮件。

$this->email->send();

例

创建一个控制器文件 Email_controller.php 并将其保存在 application / controller / Email_controller.php中 。

<?php
   class Email_controller extends CI_Controller {

      function __construct() {
         parent::__construct();
         $this->load->library('session');
         $this->load->helper('form');
      }

      public function index() {

         $this->load->helper('form');
         $this->load->view('email_form');
      }

      public function send_mail() {
         $from_email = "your@example.com";
         $to_email = $this->input->post('email');

         //Load email library
         $this->load->library('email');

         $this->email->from($from_email, 'Your Name');
         $this->email->to($to_email);
         $this->email->subject('Email Test');
         $this->email->message('Testing the email class.');

         //Send mail
         if($this->email->send())
         $this->session->set_flashdata("email_sent","Email sent successfully.");
         else
         $this->session->set_flashdata("email_sent","Error in sending Email.");
         $this->load->view('email_form');
      }
   }
?>

创建一个名为 email_form.php 的视图文件并将其保存在 application / views / email_form.php中

<!DOCTYPE html>
<html lang = "en">

   <head>
      <meta charset = "utf-8">
      <title>CodeIgniter Email Example</title>
   </head>

   <body>
      <?php
         echo $this->session->flashdata('email_sent');
         echo form_open('/Email_controller/send_mail');
      ?>

      <input type = "email" name = "email" required />
      <input type = "submit" value = "SEND MAIL">

      <?php
         echo form_close();
      ?>
   </body>

</html>

在 application / config / routes.php 中的 routes.php 文件中进行更改，并在文件末尾添加以下行。

$route['email'] = 'Email_Controller';
