(Boolean) whether the article is at the top.

Examples

Other

Add and remove functions for top articles

WordPress supports articles at the top by default, and you can put important or wonderful articles at the top in the background for users to see first.

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

However, WordPress provides two functions that make it easier to add and remove top articles, and directly call the function to modify the sticky_posts field.

Stick_post ()

The stick_post () function is used to top an article, for example:

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

Unstick_post ()

The unstick_post () and stick_post () functions, in contrast, are used to untop a top article:

Unstick_post (425); / / unset the article unstick_post (get_the_ID ()) with the top ID of 425; / / cancel the current article in the top loop. Thank you for reading!
