Just another random blog
By default WordPress allows us to use page specific templates by having files like
page-contact.php (page slug specific)
page-10.php (page ID specific)
but when it comes to custom post types, we’re left with no option but to use same template for all the custom posts of that custom post type.
We know that adding <!–nextpage–> allows you to paginate the content of the post/page in WordPress.
Also if you want to append the content you can use the_content filter.
This filter though works but adds that content to all the pages instead of creating a new page for that content.
