通過uri在codeigniter中更新Db

Question

我試圖更新數據庫中的記錄，但由於某種原因它沒有更新。也許我通過ID的方式有問題？

模型：

<?php if (! defined('BASEPATH')) exit('No direct script access allowed'); 

class site_model extends CI_Model { 




    function __construct() 
    { 
     // Call the Model constructor 
     parent::__construct(); 

    } 


    function get_records() 
    { 
     $query = $this->db->get('posts'); 

     return $query->result(); 

    } 


    function get_records_by_id() 

    { 
     $this->db->where('postID', $this->uri->segment(3)); 
     $query = $this->db->get('posts'); 

     return $query->result(); 

    } 


    function add_records($data) { 

     $this->db->insert('posts', $data); 

     return; 


    } 

    function updata_records($data) { 

     $this->db->where('postID', $this->uri->segment(3)); 
     $this->db->update('posts', $data); 



    } 

    function delede_roe() { 

     $this->db->where('postID', $this->uri->segment(3)); 
     $this->db->delete('posts'); 



    } 

} 

/* End of file welcome.php */ 
/* Location: ./application/controllers/welcome.php */ 

controoler: 

    <?php if (! defined('BASEPATH')) exit('No direct script access allowed'); 

class site extends CI_Controller { 

    /** 
    * Index Page for this controller. 
    * 
    * Maps to the following URL 
    *  http://example.com/index.php/welcome 
    * - or - 
    *  http://example.com/index.php/welcome/index 
    * - or - 
    * Since this controller is set as the default controller in 
    * config/routes.php, it's displayed at http://example.com/ 
    * 
    * So any other public methods not prefixed with an underscore will 
    * map to /index.php/welcome/<method_name> 
    * @see http://codeigniter.com/user_guide/general/urls.html 
    */ 
    public function index() 
    { 
     $this->load->view('home'); 


    } 

    function add_post() { 

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


    } 

    function creata() { 


     $data = array (
       'title' => $this->input->post('title'), 
       'post' => $this->input->post('content') 

     ); 

     $this->load->model('site_model'); 
     $this->site_model->add_records($data); 

     redirect('site/all_posts/'); 

    } 


    function edit_post() { 

     if ($query = $this->site_model->get_records_by_id()) { 


      $data['record'] = $query; 

     } 

     $this->load->view('edit_post', $data); 

     } 


     function updata() { 



      $data = array (
       'title' => $this->input->post('title'), 
       'post' => $this->input->post('content') 

     ); 

      $this->load->model('site_model'); 
     $this->site_model->updata_records($data); 

     redirect('site/all_posts/'); 

     } 



    function all_posts() { 


    if ($query = $this->site_model->get_records()) { 


      $data['records'] = $query; 

     } 

     $this->load->view('all_posts', $data); 

    } 


    function delete() { 


    $this->site_model->delede_roe(); 
    redirect('site/all_posts/'); 

} 

} 

/* End of file welcome.php */ 
/* Location: ./application/controllers/welcome.php */ 

form: 


      <?php if (isset($record)) { 



       foreach ($record as $row) { 

       echo form_open('index.php/site/updata'); ?> 

       <label for="title"> title </label> 

       <input type="text" name="title" id="title" value="<?php echo $row->title; ?>"> 


        <label for="content"> content </label> 

        <input type="text" name="content" value="<?php echo $row->post; ?>" id="content" style="width: 630px;"> 



        <input type="submit" value="׳©׳�׳—"> 

        <?php echo form_close(); }} ?> 

Answer 1

updata_records（$的數據），我認爲這個問題是存在的，模型的功能應該有$ data數組URI數據。

$data = array (
'postID' => $this->uri->segment(3), 
'post_content' => $post_content 
); 

$this->site_model->updata_records($data);
