The editor of Downcodes will take you to have an in-depth understanding of the secondary development of DedeCMS! DedeCMS (Dreamweaver Content Management System) is famous for its powerful scalability and flexible architecture. Its secondary development involves module expansion, plug-in development, template production and other aspects. This article will introduce in detail the key knowledge points of the secondary development of DedeCMS, including framework structure, template tags, module plug-in development process, system functions and class libraries, API integration and security reinforcement, etc. It also comes with answers to frequently asked questions to help you quickly master DedeCMS. Core skills of secondary development to improve website functionality and user experience.
The secondary development of DEDE (Dreamweaver Content Management System) includes module expansion, plug-in development, template production, core code modification, and API integration. Specific secondary development knowledge points include understanding the framework structure and main functions of DEDE, being familiar with the use and customization of template tags, mastering the module and plug-in development process, understanding system functions and class libraries, and security reinforcement. Among them, the most critical thing is to understand DEDE's architecture and core code, which provides the basis for effective extension and customization.
First, let’s expand on the usage and customization of familiar template tags in detail. In DEDECMS, it is a common practice to use template tags to display dynamic content. Template tags are divided into two categories: system tags and user-defined tags. Secondary development often requires writing custom tags based on specific business needs. The development of custom tags can be achieved by adding code to the template file, or through the "Module - Tag Wizard - Add Tag" method in the background. By understanding and using the template tag system, developers can flexibly output various content data and better customize personalized display logic for the website.
DEDECMS is developed based on PHP and MySQL technology and uses the MVC design pattern. In order to carry out effective secondary development, developers need to understand its framework structure:
Core files: This includes core components such as the system's entry files, controllers, models, and views. Modularity: DEDECMS allows developers to enable or disable different modules as needed, such as articles, photo albums, tags, etc. Scalability: The reason why the system supports secondary development is because of its good expansion interface and plug-in mechanism.The template is the presentation layer of DEDECMS and is responsible for the display of content. In secondary development, it usually involves:
In-depth understanding of system tags: You should be proficient in the use of system built-in tags such as loop tags, condition tags, and field tags. Development of custom tags: Developers can develop new tags for template use according to needs to achieve personalized content display.In DEDECMS, modules are a collection of system functions, and plug-ins are independent software packages that extend system functions.
Module development: including defining new content types, content lists, content pages, etc., which is an expansion of the system's content management capabilities. Plug-in development: Involves the use of system hooks, and the writing of plug-in installation and uninstallation logic.In order to interact with other systems, DEDECMS supports the integration of external services through APIs.
API integration: By writing interface code, DEDECMS can be integrated with other web services, such as social login, online payment, etc. Development of RESTful services: Create web services that can be accessed externally, such as content display interfaces called by mobile applications.Any website system needs to consider security, and DEDECMS is no exception.
Input and output filtering: Prevent attacks such as XSS and SQL injection, and maintain the security of website data. Optimization of permission control: refine background management permissions and only allow authorized users to perform specific operations. Code auditing and testing: Regularly conduct code auditing and security testing, and promptly patch possible security vulnerabilities.By mastering the above knowledge points, you will be able to better carry out secondary development of DEDECMS and make the system more in line with personalized business needs. Continuous learning and practice are the only ways to improve development skills. At the same time, understanding the latest version updates and community development trends can also help maintain development efficiency and quality.
1. What are the directions and knowledge points for the secondary development of Dedecms?
The secondary development of Dedecms mainly covers two directions: front-end and back-end. Front-end knowledge points include HTML, CSS, JavaScript, etc. Personalized UI design can be achieved by modifying templates, adjusting page layout, beautifying the interface, etc. The back-end knowledge points include PHP, MySQL, etc. Customized development of the system can be achieved by modifying the code, adding functional modules, optimizing the database, etc.
2. How to carry out secondary development of Dedecms?
To carry out secondary development of Dedecms, you first need to understand the basic architecture and core code of Dedecms. You can learn about the system framework and how to use the API interface by consulting the Dedecms documentation and development manual. Then, according to your own needs and ideas, determine the direction and goals of secondary development to be carried out. You can choose to create a new sub-module for development, or directly modify the code of an existing module. During the development process, you can use debugging tools and log functions to quickly locate and solve problems.
3. What are the advantages and precautions for secondary development of Dedecms?
The secondary development of Dedecms has rich development interfaces and support from the open source community, and can customize exclusive functions and interfaces for the website. Developers can carry out customized development according to their own needs to improve the user experience and functional expansion of the website. When conducting secondary development, attention should be paid to retaining the stability and compatibility of the original code and trying to avoid damaging the system framework and database structure. At the same time, we must follow the development specifications of Dedecms to avoid introducing unnecessary security risks and performance issues.
I hope this article can help you better understand the secondary development of DedeCMS, and I wish you smooth development! For more DedeCMS related content, please continue to follow the editor of Downcodes.
