Controller class example tutorial in php mvc_PHP tutorial-PHP Tutorial-php.cn

This article will tell you about the tutorial on the controller class in MVC. Through the previous two sections, we know that the program determines the only Moudle, Conttoller, Action through the route class of a single entry file, and finally executes

The code is as follows

Copy code

代码如下

复制代码

$route->run();

/**

* 执行相应的 MCA

private function run ()

{

$filePath = APPLICATION_PATH.'/controller/'.$this->_moudle.'/'.$this->_conttoller.'.inc.php';

$isNo = 0;

if(file_exists($filePath))

{

include "$filePath";

$controller_tp = $this->_conttoller.'Controller';

$controller = new $controller_tp;

if (method_exists($controller,$this->_action.'Action'))

{

$acion_tmp = $this->_action.'Action';

$controller->$acion_tmp();

}else

{

$isNo = 1;

}

}else

{

$isNo = 1;

}

if ($isNo)

{

$filePath = APPLICATION_PATH.'/controller/default/index.inc.php';

$this->_moudle = $this->_default['module'];

$this->_conttoller = $this->_default['conttoller'];

$this->_action = $this->_default['action'];

($this->_moudle != $this->_default['module']) && include "$filePath";

$controller = new indexController;

$controller->indexAction();

}

$route->run(); /** * Execute the corresponding MCA * */ private function run () { $filePath = APPLICATION_PATH.'/controller/'.$this->_moudle.'/'.$this->_conttoller.'.inc.php'; $isNo = 0; If(file_exists($filePath)) { include "$filePath"; $controller_tp = $this->_conttoller.'Controller'; $controller = new $controller_tp; if (method_exists($controller,$this->_action.'Action')) { $acion_tmp = $this->_action.'Action'; $controller->$acion_tmp(); } else { $isNo = 1; }else { $isNo = 1; } if ($isNo) { $filePath = APPLICATION_PATH.'/controller/default/index.inc.php'; $this->_moudle = $this->_default['module']; $this->_conttoller = $this->_default['conttoller']; $this->_action = $ ($this->_moudle != $this->_default['module']) && include "$filePath"; $controller = new indexController; $controller->indexAction(); } }

Executed when the relevant 'Controller' file exists

The code is as follows

Copy code

代码如下

复制代码

include "$filePath";

$controller_tp = $this->_conttoller.'Controller';

$controller = new $controller_tp;

include "$filePath";

$controller_tp = $this->_conttoller.'Controller';

代码如下

复制代码

$acion_tmp = $this->_action.'Action';

$controller->$acion_tmp();

$controller = new $controller_tp;

The above three lines of code mean to include the corresponding file according to the determined conttoller and instantiate the corresponding conttoller.

The code is as follows	Copy code
$acion_tmp = $this->_action.'Action'; $controller->$acion_tmp();

Execute the corresponding action according to the corresponding Action

All Controller classes integrate a common Controller class. In this lesson, we will analyze the public Controller class

/**

* Frontend public class interface

* Implement public part of the code

/**

* This file can only be indexed. php contains

defined("WEB_AUTH") || die("NO_AUTH");

/**

* Contains menu configuration file

The code is as follows

Copy code

class Controller

{

public $tpl;

public $controller;

public $body;//right menu

public $_route ;

public $html_;

public $tpl_;

* Constructor

public function __construct()

{

$this->init();

}

* Initialize variables, top menu and templates

protected function init()

{

global $TPL,$route;

$this->tpl = $TPL;

$this->_route = $route;

}

/**

* Template variable pass

protected function diplayTpl()

{

$this->body || $this->body = $this->_route->getActionName();

$this->tpl->assign("body",$this->body);

/*Set the template directory of this controller*/

$this->controller ||$this->controller =$this->_route->getControllerName();

$this->tpl->assign("controller",$this->controller);

$this->tpl->display($this->layout);

}

/**

* smarty encapsulation class

* @param string $name

* @param string $value

public function assign($name,$value)

{

$this->tpl->assign($name,$value);

}

/**

* Show additional templates

* @param string $name

* @param string $value

protected function displayOther($file)

{

$this->assign("otherTpl",TRUE);

$this->tpl->display($file);

}

/**

* Display the body template of a certain MCA

* 0=>m 1=>c =>a

protected function getMcaBody($array)

{

return 'http://www.cnblogs.com/../'.$array[0].'/body/'.$array[1].'/'.$array[2];

}

* Destructor, display page

protected function __destruct()

{

$this->tpl->_tpl_vars['otherTpl'] || $this->diplayTpl();

}

/**

* Exit midway

protected function _exit($msg = "")

{

$this->assign("otherTpl",TRUE);

die($msg);

}

/**

* Use $this->html_var=value to assign a value to the variable

* Use $this->tpl_var=value to assign a value to the variable

protected function __set($name,$value)

{

if(strtolower(substr($name,0,5)) == "html_" || strtolower(substr($name,0,4)) == "tpl_")

{

$this->assign(substr($name,5),$value);

}

首先看

这是所有Controller 类生命周期结束时候要执行的函数（搜索一下php魔术方法查看详情）

代码如下

复制代码

protected function __destruct()

{

$this->tpl->_tpl_vars['otherTpl'] || $this->diplayTpl();

}

复制代码

protected function __destruct()

{

代码如下

复制代码

protected function __set($name,$value)

{

if(strtolower(substr($name,0,5)) == "html_" || strtolower(substr($name,0,4)) == "tpl_")

{

$this->assign(substr($name,5),$value);

}

$this->tpl->_tpl_vars['otherTpl'] || $this->diplayTpl();

}

代码如下

复制代码

public $html_;

public $tpl_;

本框架利用这时候解析模板，这样的好处是，当Controller中相关执行完相关数据处理，后自动执行相关的模板（View）;而不用每次在程序最后调用模板
