How to implement article top function in PHP CMS system

In the PHP CMS system, the article top function is a very common requirement. This feature allows webmasters to prioritize certain important articles to increase the attention of website visitors. In this article, we will introduce how to implement the article top function in the PHP CMS system.

1. Modify the database

First, we need to modify the database schema and add a top flag to the top field. You can add a field to the article database table and name it top. You can use int type. A value of 1 means that it is on top, and a value of 0 means that it is not on top.

2. Modify the article list display interface

On the article list display page, you need to add a "top" column. You can use HTML elements such as Checkbox, Radio or Select for the administrator to choose whether to pin the article to the top. If selected, the value of the top field of the article is set to 1, otherwise the value of the field is 0. When the administrator selects an article to be pinned to the top, he needs to set the top value of the article to 1, and set the top value of other pinned articles to 0.

3. Sorting articles at the top

When sorting the article list, you need to consider the priority of articles at the top. You can sort by the value of the top field of the article first. Articles with a top value of 1 are sorted first, and articles with a top value of 0 are sorted by the remaining usage time. That is, the list of articles with top 1 is placed in front of the list of articles with top 0. At the same time, the articles with top 1 should be sorted by time, with the latest articles at the top.

4. Expiration of pinned articles

When there are many pinned articles, these pinned articles may occupy too long display space on the homepage. In this case, you need to consider how to handle the expiration of pinned articles. You can consider setting the expiration time of a pinned article. When the expiration time arrives, change the top field of the article to 0, indicating that the article will no longer be pinned to the top. The administrator can set the top time of the article in the article editing interface. At the same time, when the article expires, the value of the top field of the article needs to be modified at the same time.

Through the above four steps, we can implement the article top function in the PHP CMS system. Of course, during the implementation process, corresponding modifications need to be made according to the development language and framework of the specific system. However, no matter what development language and framework is used, the key is to consider article sorting and expiration issues to achieve a reliable and efficient top function.
