[WordPress] How to return status 404 on the second and subsequent pages when the top page is a fixed page
![[WordPress] How to not create author/poster archives](https://naouniverse.com/wp-content/uploads/2015/03/wordpresslogo.jpg)
naouniverse.com is built on WordPress.
The top page (https://naouniverse.com) uses home.php, and the top page of the blog (https://naouniverse.com/blog) is coded with conditional branching within page.php.
Yes, the top page is a fixed page.
There is one thing that I noticed recently.
As the number of blog articles increases, there is a serious problem that the second and subsequent pages exist in home.php.
You can access it at https://naouniverse.com/page/2...
This is not a problem for regular WordPress blogs (I think), but if you want to display a completely fixed top page like this site, page duplication will occur, which is not a good thing from an SEO perspective. )is.
I decided to deal with the problem as follows.
Returns status 404 from second page onwards
Yes, as you read, the status 404 is returned from the second page onwards.
Added the following description to functions.php.
<?php add_action( 'template_redirect', 'status404' ); function status404() { if (is_home() && is_paged()){ global $wp_query; $wp_query-> set_404(); status_header(404); } } ?>
Home.php and from the second page onwards, a status 404 is returned.
When I preview it...↓
It seems to be working well.
good···
Afterword
When I first noticed this problem, I tried various things such as writing in the Apache configuration file .htaccess (dot Htaccess), but it didn't work.
It seems safe to write it in functions.php above.
