讨论一下mvc的C和V的维护性和健壮复用性

本帖最后由 A9925 于 2015-01-17 17:49:33 编辑 mvc大家都很熟, 基本的结构也很明白。

今天我想和大家讨论一下,
其中控制层中,一个控制器里有多少个方法为合适,
以及,一个显示层是否可以多次重复调用(像增加用户页面和修改用户页面基本上是一样的)。

如果增加和修改用一个页面的话,势必会在view中写过多的逻辑判断,判断是增加控制层进来的,还是修改层进来的,以及,做完增加或修改后跳到哪个相应的控制层。 (这些都要在显示层给个action的值,或name属性,又或都get或post提交 这些判断来传到不同的控制层。)

因为在维护一个旧系统,感到很困惑。
给大家贴段代码看看以前旧项目的代码,哪需要提高,因为每次进到一个function中,都要不断的分析这个function是做什么的,维护起来,读代码的时间太浪费。请大家不吝赐教。

举例:控制层  //写的是修改成员 但里面有些功能不是修改成员数据,这只是一个文件,项目中其它地方的代码也都类似,甚至更多,每次进到方法里要走一遍流程才知道到底执行哪个,以及在哪跳出。 甚至跳出的地方用一个控制器的名称代替view(XXX.php) ,从而重复上边我说的,进入到又一次循环分析代码中。  维护起来很不方便。 需要怎么理这思路,以及以后注意哪方面进行提高 ,希望提些建设性的意见,谢谢。

------解决思路----------------------
按模块化设计原则:有一个入口,一个出口。一个模块完成一件事情
显然你的设计是不符合的

------解决思路----------------------
$inUserid = $_GET['id'];   

不用判斷參數合法性嗎?很危險啊。

if($_POST['action']=="add"){ 。。。。

 if($_POST['action']=="alert"){

你只是做了分支,並沒有按模塊分function處理。
