How to hide wap.php in thinkphp

With the popularity of mobile Internet, more and more web applications need to support mobile phone access, so many sites will have a dedicated WAP site to facilitate users to access on mobile devices. However, accessing WAP sites through URLs is not very friendly. URLs usually have suffixes such as "wap.php", which causes trouble for users. This article will introduce a method to hide "wap.php" to make the WAP site more friendly.

1. Introduction

thinkphp is an open source PHP framework. It is based on object-oriented programming and relies heavily on the MVC design pattern. It encapsulates the ORM layer and connects Data source to quickly develop web applications. For thinkphp applications that need to support WAP layout, hiding "wap.php" is an effective method to improve user access experience.

2. Idea analysis

In the thinkphp framework, URL address mapping and routing rules are responsible for the core routing component. Therefore, we can achieve the purpose of making the WAP site URL friendly by modifying the routing rules and hiding the "wap.php" suffix. The specific implementation method is as follows:

1. Modify the App/Conf/config.php file:

'URL_ROUTER_ON'   => true,
'URL_ROUTE_RULES' => array(
    'wap'        => 'Index/Wap/index',
    ':action'   => 'Index/:1',
),

2. Create a Wap module and modify the Action corresponding to the module:

class WapAction extends Action {
    public function _empty() {
        $this -> display('Index:index');
    }
    public function index() {
        $this -> display();
    }
}

3. Implementation steps

1. Create Wap module

In thinkphp, an application can build multiple modules. A module is an independent directory and contains independent views. and controller. We can create a Wap module by executing the following command:

php thinkphp.php -m -a Index -s Wap

After executing this command, the Wap directory will be created in the application directory, and an Index controller will be created in this directory. We need to rename this controller to WapController.class.php.

2. Modify the App/Conf/config.php file

Modify the routing rules in the configuration file and map "wap" to the Index controller of the Wap module.

'URL_ROUTER_ON'   => true,
'URL_ROUTE_RULES' => array(
    'wap'        => 'Wap/Index/index',
    ':action'   => 'Index/:1',
),

At this time, when the user visits "http://example.com/wap", the indexAction method of the Index controller of the Wap module will be called.

3. Modify the Wap module controller

Modify the Index controller in the Wap module to hide the "wap.php" suffix. First, we need to intercept all non-existing methods through the _empty() method. When the specified method does not exist in the Wap module, the result specified in the _empty() method will be executed, and we can return to render the specified template file. For example:

class WapController extends Controller {
    protected $is_wap = true;
    public function _empty() {
        $this -> display('Index:index');
    }
    public function index() {
        $this -> display();
    }
}

When a method does not exist, _empty() will be executed and the Index:index template will be rendered.

4. Summary

By modifying the routing rules and module controller of the thinkphp framework, we can hide the "wap.php" suffix and improve the friendliness of the WAP site URL. degree, thereby improving user experience. By intercepting non-existent methods, we can also achieve error handling and prevent the site from being crawled by crawlers.
