Add and remove top posts
By default, WordPress supports the article top function. You can pin important or brilliant articles on the background to give users a higher priority.

During development, you may need to add and remove top articles through code. The principle of WordPress pin-to-top article is to store the ID of the pin-to-top article in the options table, and control the pin-to-top article by modifying the sticky_posts field.

However, WordPress provides two functions to easily add and remove the sticky_posts field by directly calling the function.

Stick_post ()

The stick_post () function is used to top an article. Example:

Stick_post (68); // stick_post (get_the_ID () of the article with the top ID 68; // the current article in the top loop

Unstick_post ()

The unstick_post () function is opposite to the stick_post () function to unpin a top article:

Unstick_post (425); // unstick_post (get_the_ID () of the article whose top ID is 425; // unstick_post (get_the_ID ()
