DedeCMS database customization modification practical guide

With the rapid development of the Internet, website construction has received more and more attention. As an excellent CMS system, DedeCMS has a wide range of applications in the field of website construction. However, for some specific needs, the default functionality of DedeCMS may not be fully satisfied. At this time, it is necessary to make customized modifications to its database to achieve more personalized functions.

1. Database structure analysis

First, we need to analyze the database structure of DedeCMS. DedeCMS uses a MySQL database to store website data, mainly including content models, columns, articles, comments and other information. By analyzing the database structure, we can determine the tables, fields and relationships that need to be modified.

2. Preparation work

Before making customized modifications to the database, you need to make preparations. First, back up the database to avoid data loss due to operational errors. Secondly, establish a new test environment and perform modification operations in this environment to avoid affecting the normal operation of the online website.

3. Database customized modification operation

The following uses a practical example to introduce how to customize the database of DedeCMS to achieve specific functional requirements.

3.1 Add a new custom field

Suppose we need to add a new custom field "Author" to the article model to record the author information of the article.

First, add a new field in the "dede_addonarticle" table:

ALTER TABLE `dede_addonarticle` ADD `author` VARCHAR(50) NOT NULL DEFAULT '';

Then, modify the template file of the article publishing page and add an input box for the author field so that users can enter author information.

Finally, when saving the article information, save the author information to the corresponding field in the "dede_addonarticle" table.

3.2 Modify column association rules

Suppose we need to set articles in a specific column to be displayed on top.

First, find the record of this column in the "dede_arctypes" table, assuming that the column ID is 1.

Then, find the typeid corresponding to this column in the "dede_arctiny" table, assuming it is 1.

Next, find the define of the column in the "dede_arctype" table, that is, the column association rule. Add "top=1" to this field to indicate that the articles under this column need to be displayed at the top.

Finally, in the page template that displays the article list, the article display is adjusted according to the rules of the define field, and the top article is displayed in the front.

4. Testing and Launch

After completing the customized modification of the database, testing is required to ensure the normal operation of the function. User operations can be simulated in the test environment to check whether the new functions meet expectations. If everything goes well, the modified database can be deployed to the online environment so that users can experience the convenience of the new features.

In general, customized modifications to the DedeCMS database need to be combined with specific needs and have a certain understanding of the database structure. Be careful during operation to ensure data integrity and security. We hope that the practical guide in this article can help readers successfully implement customized modifications to DedeCMS functions.
