注册后发送激活码

Question

这是我的简单注册。我想在提交此注册form.How按钮后发送电子邮件给用户，我可以这样做吗？？提前谢谢。1.在视图中，我做了一个简单的注册表，如您所见，我添加了一些基本信息。2.在我的控制器中添加了验证。并将它们保存在数据库中。4.模型具有简单的插入查询。

form_view.php

<table>
    <tr>
        <td>Name</td><td><?php echo form_input($name);?></td>
        <td><?php echo form_error('name');?></td>

    </tr>
    <tr>
        <td>Email</td><td><?php echo form_input($email);?></td>
        <td><?php echo form_error('email');?></td>

    </tr>


<tr>
        <td>Phone</td><td><?php echo form_input($phone);?></td>
        <td><?php echo form_error('phone');?></td>

    </tr>

    <tr>
        <td>Address</td><td><?php echo form_input($address);?></td>
        <td><?php echo form_error('address');?></td>

    </tr>

       <tr>
           <td>Division</td><td><?php echo form_dropdown('division',$division,'Please Select');?></td>

    </tr>

          <td></td><td><?php echo form_submit($submit);?></td>

    </tr>


</table>

main.php

 <?php

    class main extends CI_Controller{
    public function viewForm(){

            $this->load->view('form_view');


        }

        public function insertData(){
            $this->load->library('form_validation');
            $this->form_validation->set_rules('name', 'Full Name', 'required|min_length[5]|max_length[12]|is_unique[address.name]');
            $this->form_validation->set_rules('phone', 'Contact field', 'required|min_length[5]|max_length[12]|is_unique[address.phone]');
            $this->form_validation->set_rules('address', 'Full Address', 'required|min_length[5]|max_length[12]|is_unique[address.address]');
              $this->form_validation->set_rules('email', 'Email Address', 'required|min_length[5]|max_length[12]|is_unique[address.email]');
            if($this->form_validation->run()==FALSE){
           $this->load->view('form_view');     
            }else{

            $sql="Select MAX(id) from address";// Auto Increment
            $query=  mysql_query($sql);
            $selectid=  mysql_fetch_array($query);
            $finalid=$selectid[0]+1;

            $data=array();
            $data['id']=$finalid;

            $data=array();
            $data['name']=$this->input->post('std_name');
            $data['phone']=$this->input->post('std_phone');
            $data['address']=$this->input->post('std_address');
            $data['division']=$this->input->post('division');
            $data['email']=$this->input->post('email');

            $this->load->model('main_model');
            $this->main_model->save_user($data);
            redirect('main/viewForm');
          }
        }

main_model.php

 <?php

    class main_model extends CI_Model{
        public function save_user($data){
        $this->db->insert('address',$data);

        }
    ?>

    }
    ?>

您可能需要考虑在用户info表中添加两列。比如varchar activation_code & tinyint activated。在保存用户信息时，生成激活码，并在您的应用程序url的链接中向用户发送带有该代码的邮件，并使用激活的false值为该特定用户保存该代码。验证使用该链接的代码是否已激活为true。这将是我的方法。

在我们开始之前，我只想指出你的控制器中不应该有查询。该零件必须在模型中。

要发送电子邮件，您可以使用codeigniter的库：https://ellislab.com/codeigniter/user-guide/libraries/email.html

以下是如何在您的案例中使用它：

if($this->form_validation->run()==FALSE)
{
   $this->load->view('form_view');     
}
else
{
     $email = $this->input->post('email');

    //Your stuff before the redirect

    //If you have any particular smtp configuration (here, gmail)
    $config = Array(
         'protocol'  =>  'smtp',
         'smtp_host' =>  'smtp.gmail.com',
         'smtp_user' =>  'myemail@gmail.com',
         'smtp_pass' =>  'mypassword',
         'smtp_port' =>  '465',
         'charset' => 'utf-8',
         'wordwrap' => TRUE
     );

    $this->load->library('email', $config);
    $this->email->from('MyName@MySite.com', 'MyName');
    $this->email->to($email); 
    $this->email->subject('Mail subject');
    $msg = "Welcome to my website !";
    $this->email->message($msg);

    if($this->email->send())
    {     
        //Stuff if mail succeded
    }
    else 
    {
        //Stuff if mail failed
    }

    redirect('main/viewForm');

}
