封裝MVC(五)

        完成封裝（四）後，新建model.class.php，代碼如下：

<?php

    class Model extends SQLQuery{

        protected $_model;

        function __construct() {

            $this->connect(DB_HOST,DB_USER,DB_PASSWORD,DB_NAME);

            $this->_model = get_class($this);

            $this->_table = strtolower($this->_model)."s";

        }

        function __destruct() {

        }

    }

         如圖所示：

               

          

           新建視圖基類爲template.class.php，具體代碼如下：

 

<?php

    class Template {

       protected $variables = array();

       protected $_controller;

       protected $_action;

       function __construct($controller,$action) {

           $this->_controller = $controller;

           $this->_action =$action;

       }

       /* 設置變量 */ 

       function set($name,$array)
       {
            if(!empty($name)){

               $this->_action = $name;
            }
            $this->variables = $array;
       }

       /* 顯示模板 */

       function render() {

           if(!empty($this->variables)){
                foreach ($this->variables as $key => $value) {

                    extract(array($key=>$value));    //將變量導入當前符號表
                }
           }

           if (file_exists(ROOT.DS. 'application' .DS. 'views' .DS. $this->_controller .DS. 'header.php')) {

               include(ROOT.DS. 'application' .DS. 'views' .DS. $this->_controller .DS. 'header.php');

           } else {

               include(ROOT.DS. 'application' .DS. 'views' .DS. 'header.php');

           }

           include (ROOT.DS. 'application' .DS. 'views' .DS. $this->_controller .DS. $this->_action . '.php');

           if (file_exists(ROOT.DS. 'application' .DS. 'views' .DS. $this->_controller .DS. 'footer.php')) {

               include (ROOT.DS. 'application' .DS. 'views' .DS. $this->_controller .DS. 'footer.php');

           } else {

               include (ROOT.DS. 'application' .DS. 'views' .DS. 'footer.php');

           }

        }

    }

       如圖所示：

             

       做完了以上這麼多操作，基本上整個MVC框架已經出來了，下面就該製作我們的站點了。我們要做的站點其實很簡單，一個ToDo程序。
