Implementation method of multiple templates developed in PHP in WeChat mini program

With the popularity of WeChat mini programs, more and more developers are beginning to use WeChat mini programs to develop applications. The PHP language has become one of the most popular development languages. This article will introduce how to use PHP multi-template implementation in WeChat mini programs.

1. What is multi-template

Multi-template means that there can be multiple templates in an application, and different templates can be loaded according to different needs. In web development, most use the MVC structure, and select different views through the controller to implement multiple templates. In the WeChat applet, since there is no concept of a controller, another method needs to be used to implement multiple templates.

2. Methods to implement multiple templates

1. Use PHP template engine

PHP template engine can completely isolate PHP code and HTML code, realizing template and The separation of business logic makes it easier to maintain than the original PHP code and improves the reusability of the code. Therefore, you can use the PHP template engine to implement multiple templates.

There are many open source PHP template engines, such as Smarty, Twig, etc. Here we take Smarty as an example. Smarty is very simple to use. You only need to import the Smarty.class.php file and instantiate it.

It should be noted that when using Smarty, the template file and the compiled file need to be stored in different locations, otherwise it will cause security issues. Security issues mainly come from Smarty's parsing of template tags. If the compiled files are stored in the Web directory, users can directly access these files through URLs, which will cause security risks.

2. Use the template function of the WeChat applet to manage the background

The WeChat applet provides the template function of the management background. You can add multiple templates in the "template list" of the management background, and Correspond to different message templates respectively. As needed, different templates can be dynamically selected for use in the code.

When using the template function of the WeChat applet management backend, you need to add a template in the management backend first. After adding a template, you can see the template ID and other information of the template in the background, and save the template ID in the code. The corresponding template can then be used via the template ID.

It should be noted that when using the template function of the WeChat applet management backend, you need to authenticate first and use the corresponding API on the front end for access.

3. Summary

This article introduces the implementation method of using PHP multiple templates in WeChat mini programs, including using the PHP template engine and using the template function of the WeChat mini program management background. Among them, using the PHP template engine is relatively simple, and you can make full use of the performance advantages of the PHP template engine; using the template function of the WeChat applet management backend to design authentication issues for the WeChat public platform requires attention to some details.

No matter which method is used, implementing multiple templates will have great benefits for the scalability and maintainability of the application. Therefore, when developing WeChat mini programs, especially when it is necessary to implement services such as message push, multiple templates will be a very effective solution.
