How Do I Enforce One Category Per Post in WordPress?

In order to enforce one category per post in WordPress, you will need to create a custom post type. To do this, open the WordPress admin panel and go to:

WordPress Custom Post Types

Select the “Add New” button and enter the following information into the “Name” field:

“One Category Per Post”

Click the “Create” button to create the new post type.

Now that the new post type has been created, you will need to set up some rules to enforce the category limit. To do this, go to the “Posts” screen and click on the “edit” link next to the post that you want to set the category limit for.

In the “Post Details” screen, under the “Category” field, you will need to enter the ID of the category that you want to limit posts to.

Next, you will need to set the “Max Posts” field to the number of posts that you want to be allowed per category.

Finally, you will need to set the “Is Default” field to “Yes”. This will make the post type the default for posts that don’t have a specific category assigned to them.

Now that the category limit has been set up, you will need to activate it. To do this, go to the “Settings” screen and click on the “General” link.

Under the “Post Types” heading, click on the “One Category Per Post” post type to activate the limit.

Conclusion

Enforcing one category per post in WordPress can be a useful way to keep your blog organized and tidy. By setting up a custom post type and activating the category limit, you can easily keep track of which posts are assigned to which categories.
