成功注册后，当我刷新页面时，它会进入索引页面。

Answer 1

if ($x['error']=='')
   {
   $this->user_model->register_user($data['img']);
   $this->load->view('register_view');
   }

将此更改为

if ($x['error']=='')
   {
   $this->user_model->register_user($data['img']);
   redirect('home/registersuccess');
   }

编写新功能

function registersuccess(){
    $this->load->view('register_view');
}
