phpcms(1)phpcms V9 MVC mode and URL access parsing (transfer), phpcmsmvc

[1]URL access parsing

Observe the URL when accessing the web page , you can get the module access method, as shown in the following example:

http://www.abcd.com.cn/phpcms/index.php?m=content&c=index&a=show&id=1

The parsing of this URL is as follows:

m = content is the module/model name located in phpcms/modules/content (Required )

c = index is the controller name located phpcms/modules/content/index.php (Required)

a = show is the event name located in the show method in phpcms/modules/content/index.php

id = 1 is the same as the normal get passed parameter form for other parameters

Then, here comes the problem! The URL we often visit on the homepage is: http://www.abcd.com.cn/phpcms/index.php Why are there no values ​​for m and c?

Let me explain here, when the system does not specify a module or controller, it will execute the default module and operation. For the above URL, the PHPCMS default route will locate the init operation in the index controller of the content module. Therefore, the result is the same as the following URL:

http://www.abcd.com.cn/phpcms/index.php?m=content&c=index&a=init

The system also supports URL routing functions, these can bring other URL access effects.

The routing file is located at phpcmscachesconfigsroute.php and the content is organized as follows:

 1 <?php
 2 /**
 3  * 路由配置文件
 4  * 默认配置为default如下：
 5  * 'default'=>array(
 6  *     'm'=>'phpcms', 
 7  *     'c'=>'index', 
 8  *     'a'=>'init', 
 9  *     'data'=>array(
10  *         'POST'=>array(
11  *             'catid'=>1
12  *             ),
13  *         'GET'=>array(
14  *             'contentid'=>1
15  *             )
16  *         )
17  * )
18  * 其中“m”为模型,“c”为控制器，“a”为事件，“data”为其他附加参数。
19  * data为一个二维数组，可设置POST和GET的默认参数。
20  * POST和GET分别对应PHP中的$_POST和$_GET两个超全局变量。
21  * 在程序中你可以使用$_POST['catid']来得到data下面POST中的数组的值。
22  * data中的所设置的参数等级比较低。如果外部程序有提交相同的名字的变量，将会覆盖配置文件中所设置的值。
23  * 如：外部程序POST了一个变量catid=2那么你在程序中使用$_POST取到的值是2，而不是配置文件中所设置的1。
24  */
25 return array(
26     'default'=>array('m'=>'content', 'c'=>'index', 'a'=>'init'),
27 );

For a more specific understanding, a simple example is as follows:

1. In the phpcms/modules directory, create a new folder and name it demo, that is, the module name is demo

2. In the demo folder, create a new text file, name it test, and change the file type to php. Open the test file with Notepad and edit the content as follows:

1 <?php
2     class test
3     {
4         public function show()
5         {
6             echo "I Love PHPCMS V9.";
7         }
8     }
9 ?>

Note: The content in test.php must be written in class, otherwise it will prompt that control cannot be found, that is, c in mvc cannot be found. If a is not specified, the init method is called. If the init method is not implemented, it will display: Action does not exist.

3. Enter in the browser’s URL bar: http://localhost/phpcms/index.php?m=demo&c=test&a=show and press Enter. The result is as shown below:

【2】Module

The modules in the phpcms V9 framework are located in the phpcms/modules directory. Each directory is called a module. That is the m in the URL access above.

If you need to create a module, just create a folder in the phpcms/modules directory and put your controller class in it.

【3】Controller

Regarding the controller class, please refer to the article "phpcms V9 Adding Modules"

Good Good Study, Day Day Up.
