Pagination questions

Question 1: Is it possible to add pagination to pages?

Yes, it is possible to add pagination to web pages. Pagination is a common technique used to split large amounts of content into smaller, more manageable sections. It allows users to navigate through the content easily by providing links or buttons to access different pages.

Question 2: How do I make it so that the pagination is limited to the content within a certain work? In the page I need help with, I don’t want the pagination to extend beyond the last page.

To limit the pagination to the content within a certain work and prevent it from extending beyond the last page, you’ll need to consider the specific structure of the content and apply appropriate logic in your pagination implementation.

In the case of the page you mentioned, https://manga.bunnyhoofsart.com/vasilisa-the-beautiful/, it appears to be a web page hosting manga content. Here’s how you can approach limiting the pagination to the manga content:

1. Determine the total number of pages: Identify the total number of pages for the manga content. This can be based on the total number of chapters, episodes, or other relevant divisions within the work.
2. Establish the desired content per page: Decide how many pages or panels from the manga you want to display per pagination page. This will depend on the layout and design of the web page and how much content you want to present at once.
3. Implement pagination logic: Based on the total number of pages and the desired content per page, implement the pagination logic. Ensure that the pagination links or buttons are generated only within the range of valid pages for the manga. For example, if the manga has 50 chapters and you want to display 10 chapters per page, the pagination should be limited to 1 to 5 (as there are 5 pages in total).
4. Update the content dynamically: When a user interacts with the pagination links, use JavaScript or a server-side programming language to dynamically fetch and display the relevant manga content for the selected page. This can involve retrieving the appropriate chapters or sections from your data source and updating the page with the new content.
5. Handle boundary cases: Consider scenarios where users try to access pages beyond the valid range. You can handle this by redirecting them to the first or last valid page or by displaying an appropriate message indicating that the requested page is not available.

By implementing these steps, you can ensure that the pagination is limited to the content within a certain work, such as a manga, and prevent it from extending beyond the last page.

Ok. Is there a way to redirect users to the first page from the last valid one?

There’s a way, but it seems illogical to me. If you have a page with valid content, why would you redirect away from it? Or do you want to redirect invalid page requests back to the first page? Either way, the procedure is the same.

You cannot redirect with PHP once output has begun. You’d need to redirect from an early “request” filter or similar. Your callback would need to confirm the request is for an invalid page on every request, valid or not, target page or not. Not terribly efficient but doable. IMO it’s better to just let the template report nothing found (soft 404 error).

You can however redirect via JavaScript at any time. Instead of outputting the usual “Nothing found” message on a template, you could output a <script> block that redirects to page 1. You could even build in a brief delay so a message can be seen prior to redirecting.

FWIW, there is a page break block where you can divide up a single page’s content into multiple section. WP will then generate pagination links for you.

If the page’s content is comprised of custom query results that you’d like to paginate, you can use the paginate_links() function.

Alright. Added all the necessary pages. Now how do I redirect users to the first page(0) from the last page(FIN)?

It occurs to me I may be misinterpreting your use of the term “redirect”. To me it means to automatically take the user somewhere else as an immediate response for requesting the last page. Thus they’d never see the last page (or see it only very briefly). If I request page FIN, right away I’d be taken to page 0 instead.

That’d be very unusual and seems undesirable to me. It can be done, but I don’t see the reason for it. More typically, on the last page there might be a navigation link taking one back to the beginning. Sometimes the nav links might look like << < page title > >> where the single angle brackets go to previous/next pages and the double ones go to the very beginning or end. Of course on the last page the right pointing brackets would not exist or would be grayed out and non-functional.

Might you be wanting a nav link back to the beginning and not a “redirect” as I understand it?

A nav link back to the first page is desired

If you don’t have too many pages you could set the “show_all” arg for paginate_links() to true.

Otherwise conditionally output an explicit link to the first page as part of the template code when the current page is the same as the query’s max_num_pages. You can get the URL for the link from get_pagenum_link(1)

I’m sorry, I’m confused XD

I’m not sure which pagination function you’re using to paginate, maybe it’s me that’s confused ??

If you use paginate_links(), you can get it to output links to all pages on every page. Not a good option if you have a lot of pages.

Aside from that, pagination functions will not put up a link from last back to the start. You’ll need code to do that independent of the pagination function output. Here’s an example, but it’s out of context. You’ll need to adjust for your specific situation.

global $wp_query;
if ( $current_page == $wp_query->max_num_pages ) {
   $url = get_page_num_link(1);
   echo "<a href=\"$url\">First Page</a>";
}
// you normal pagination function follows
