Is it possible to modify the output of pagination urls?

Question

I'm currently using the following code for pagination:

{pagination_links}
    {page}
        <a href="{pagination_url}">{pagination_page_number}</a>
    {/page}
{/pagination_links}

Because of an addon I'm using, I need to modify the output of the {pagination_url} variable.

{pagination_url} outputs http://sitename.com/blog/P20, and I need to add a segment before blog.

I attempted to use the Find and Replace Plus addon, but due to the parse order, I'm not able to use the {site_url} variable to find/replace.

Is there an easier way to accomplish this?

Answer 1

If you just need to modify the part of the URL before the pagination segment (and your use case is relatively simple) you can use the paginate_base parameter on your entries loop (docs here):

{exp:channel:entries paginate_base="blog/foo"
  {pagination_links}
    {page}
        <a href="{pagination_url}">{pagination_page_number}</a>
    {/page}
  {/pagination_links}
{/exp:channel:entries}

Now your output should look like this: http://example.com/blog/foo/P20

If you're feeling brave, you can also head to:

system/codeigniter/system/libraries/Pagination.php

All of the opening and closing elements are there and you can override them. Just make a note of those changes so you can restore them after an upgrade.
