模型中的第二個參數是什麼（「pagemodel」，'pages'）

Question

我有以下模型和控制器。而數據庫表頁面有ID，標題，內容和slu。。

Q1。爲什麼控制器中的線路，

$this->load->model("pagemodel", 'pages'); // Load the page model, 

有'網頁'？

它是否將頁面模型命名爲頁面？

我看一條線，

$page_data = $this->pages->fetch($page_slug); // Pull the page data from the database 

使用的頁面。

型號代碼

<?php 

class Pagemodel extends Model 
{ 

    /** 
    * Constructor 
    */ 
    function Pagemodel() 
    { 
     parent::Model(); 
    } 

    /** 
    * Return an array of pages — used in the manage view 
    * 
    * @access public 
    * @return array 
    */ 
    function pages() 
    { 
     $query = $this->db->query("SELECT * FROM `pages` ORDER BY `id` ASC"); 
     return $query->result_array(); 
    } 

    /** 
    * Return a list of a single page — used when editing a page 
    * 
    * @access public 
    * @param integer 
    * @return array 
    */ 
    function page($id) 
    { 
     $query = $this->db->query("SELECT * FROM `pages` WHERE `id` = '$id' LIMIT 1"); 
     return $query->result_array(); 
    } 

    /** 
    * Return an array of a page — used in the front end 
    * 
    * @access public 
    * @param string 
    * @return array 
    */ 
    function fetch($slug) 
    { 
     $query = $this->db->query("SELECT * FROM `pages` WHERE `slug` = '$slug'"); 
     return $query->result_array(); 
    } 

    /** 
    * Add a record to the database 
    * 
    * @access public 
    * @param array 
    */ 
    function add($data) 
    { 
     $this->db->query("INSERT INTO `pages` (`title`, `content`, `slug`) VALUES (".$this->db->$data['title'].", ".$this->db->$data['content'].", ".$this->db->escape($data['slug']).")"); 
    } 

    /** 
    * Update a record in the database 
    * 
    * @access public 
    * @param integer 
    * @param array 
    */ 
    function edit($id, $data) 
    { 
     $this->db->query("UPDATE `pages` SET `title` = ".$this->db->escape($data['title']).", `content` = ".$this->db->escape($data['content']).", `slug` = ".$this->db->escape($data['slug'])." WHERE `id` = '$id'"); 
    } 

    /** 
    * Remove a record from the database 
    * 
    * @access public 
    * @param integer 
    */ 
    function delete($id) 
    { 
     $this->db->query("DELETE FROM `pages` WHERE `id` = '$id'"); 
    } 

} 

?> 

控制器代碼

<?php 

class Page extends Application 
{ 

    function Page() 
    { 
     parent::Application(); 
     $this->load->model("pagemodel", 'pages'); // Load the page model 
    } 

    function _view($page, $page_data) 
    { 
     $meta = array (
     'meta_title' => 'title here', 
     'meta_keywords' => 'keywords here', 
     'meta_description' => 'description here', 
     'meta_robots' => 'all', 
     'extra_headers' => ' 
     <script language="javascript" type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.0/jquery.min.js"></script> 

     ' 
     ); 

     $data = array(); 
     // add any data 

     // merge meta and data 
     $data = array_merge($data,$meta); 

     // load view with data 
     $this->load->view('header', $data); 


     $this->load->view($page, $page_data); 
     $this->load->view('footer'); 
    } 

    function index() 
    { 
     $page_slug = $this->uri->segment('2'); // Grab the URI segment 

     if($page_slug === FALSE) 
     { 
      $page_slug = 'home'; //Change home if you change the name in the back-end 
     } 

     $page_data = $this->pages->fetch($page_slug); // Pull the page data from the database 

     if($page_data === FALSE) 
     { 
      show_404(); // Show a 404 if no page exists 
     } 
     else 
     { 
      $this->_view('index', $page_data[0]); 
     } 
    } 




} 

?> 

Answer 1

從系統/庫/ Loader.php

/** 
* Model Loader 
* 
* This function lets users load and instantiate models. 
* 
* @access public 
* @param string the name of the class 
* @param string name for the model 
* @param bool database connection 
* @return void 
*/ 
function model($model, $name = '', $db_conn = FALSE) 
{ 
    ... 

所以，是的，第二個參數是剛剛設置模型中的「友好」的名稱，並且不需要。它在我看來增加了一層混淆。

你可能是正確的，嘗試重命名「頁」和我打賭它不是提供了通過調用控制器 $這個 - >頁碼。
