在codeigniter中获取URL中的最后一个insert_id

Question

我的应用程序中有一个要求..所以当用户在要求中插入详细信息时.然后提交..邮件将通过一个链接发送到特定供应商..当供应商单击链接时我重定向页面到登录页面..

所以我想做的是我想用最后插入的 id 发送电子邮件链接..

这是我的控制器：

public function requirement()

{

  $data["msg"]="";
  $this->load->model('RequirementModel');
  $data['user']=$this->RequirementModel->getusers();
  $data['rolename']=$this->RequirementModel->getrolename();


if($this->input->post())
 {

   $this->RequirementModel->add_requirement($this->input->post());
   $all_users = $this->input->post('user_id');
   foreach($all_users as $key)
      {
         $get_email = $this->RequirementModel->get_user_email_by_id($key);
         $req_id = $this->input->post('req_id');
         $role_name = $this->input->post('role_name');
         $vacancies = $this->input->post('vacancies');
         $experience = $this->input->post('experience');
         $jd = $this->input->post('jd');
         $hiring_contact_name = $this->input->post('hiring_contact_name');
         $hiring_contact_number = $this->input->post('hiring_contact_number');
         $config = Array(
          'protocol' => 'smtp',
          'smtp_host' => 'ssl://md-in-42.webhostbox.net',
          'smtp_port' => 465,
          'smtp_user' => 'test3@clozloop.com',
          'smtp_pass' => 'test3'
      );
         $this->load->library('email',$config);
         $this->email->set_mailtype("html");
         $this->email->from('test3@clozloop.com', 'bharathi');
         $this->email->to($get_email); 
         $this->email->subject('this is our requirements pls go through it');
         $link = 'Click on this link - <a href="http://localhost/job_portal/index.php/Login/signin>Click Here</a>';
         $this->email->message($link);
         print_r($get_email);
         if($this->email->send())
         {

              echo "email sent";
          }
          else
          {
              echo "email failed";
          }

}

}

$this->load->view('Requirements/requirements',$data);

}

谁能帮帮我.. 提前谢谢..

你需要的是数据库辅助函数insert_id()，它返回最后插入的id：https://www.codeigniter.com/userguide3/database/helpers.html?highlight=insert_id

让 RequirementModel 模型的 add_requirement 函数返回 insert_id，如下所示：

return $this->db->insert_id();

然后在调用函数时保存该值：

$insert_id = $this->RequirementModel->add_requirement($this->input->post());
