在 Codeigniter 中刷新相同 url 时，控制器正在从一个视图重定向到另一个视图

Question

我有 create_student 视图，它只获取学生姓名并生成自动递增主键 ID，user_info 会话在用户登录后保存，如果存在验证错误 create_student 视图，否则会从 student_model 返回最近插入的学生 ID 和学生详细信息的视图已打开，即 student_detail 视图。

问题出在我刷新这个 url http://localhost/MyProject/create_student/Create_Student 我从 student_detail 视图转到第一个视图，即 create_student，每次我在 student_detail 查看重复学生条目时重新加载此 url 每次都保存在数据库中。请帮助解决我的问题。

create_student Controller:

public function Create_Student() {


   $this->form_validation->set_rules('student_title', 'Create Student', 'trim|required|xss_clean');
   $this->form_validation->set_error_delimiters('<div class="error">', '</div>');

   $course_name=$this->input->post('title_title');  
   $user_info=$this->session->userdata('user_info');
   $user_id=$user_info['id'];

   if ($this->form_validation->run() == FALSE) 
   {
    $this->load->view('create_student');
   }
   else
   {

    $data=array('u_id'=>$user_id,'course_title'=>$course_name);
    $result_student = $this->student_model->Create_Student($data);

    if($result_course!=false)
    {
        $data['result'] = $result_student;
        $this->load->view('student_detail',$data);
    }
    else
    {
        $this->load->view('create_student');

    }
   }

}

create_student View:

    <?php echo form_

open('create_student/Create_Student') ?>
  <?php echo validation_errors(); ?>
  <input type="text" class="middle" name="student_title" class="middle"/>
  <button class="middle green" name="submit" type="submit">Create Student</button>
<?php echo form_close();  ?>

Student_Model :

public function Create_Student($data) {

   $this->load->database();
   $this->db->insert('user', $data);
   $insert_id = $this->db->insert_id();
   if ($this->db->affected_rows() > 0) {
   return $insert_id;
   }
   else
   {
   return false;
   }
}

在 Controller 中试试这个编码

<?php create_student Controller:
public function Create_Student() {


   $this->form_validation->set_rules('student_title', 'Create Student', 'trim|required|xss_clean');
   $this->form_validation->set_error_delimiters('<div class="error">', '</div>');

   $course_name=$this->input->post('title_title');  
   $user_info=$this->session->userdata('user_info');
   $user_id=$user_info['id'];

   if ($this->form_validation->run() == FALSE) 
   {
    $this->student();
   }
   else
   {

    $data=array('u_id'=>$user_id,'course_title'=>$course_name);
    $result_student = $this->student_model->Create_Student($data);

    if($result_student)
    {
        redirect('create_student/student_details/'.$result_student);
    }
    else
    {
        $this->student();
    }
   }

 public function student_details() {
         $data['result'] = $this->uri->segment(3);
        $this->load->view('student_detail',$data);
 }

 public function student() {
      $this->load->view('create_student');
 }

}
?>
