• What would you like it to show? – Krzysiek Dróżdż Commented Jan 14, 2019 at 14:39
• Also, what's the context here? The function already has 2 arguments that allow you quite a bit of customisation at the moment of use, so a filter shouldn't be necessary. Are you working from a child theme? – Jacob Peattie Commented Jan 14, 2019 at 14:41

You can't easily change only the URL of that link, because there is no filter that will allow you to do that, but...

next_post_link uses get_next_post_link. There are no filters in any of these functions, but... get_next_post_link uses get_adjacent_post_link and inside of that function you can see {$adjacent}_post_link hook.

So now we can check docs for that hook. And then write some code:

function my_next_post_link($output, $format, $link, $post, $adjacent) {
    return '<a href="<MY LINK">MY LINK LABEL</a>';
}
add_filter( 'next_post_link', 'my_next_post_link', 10, 5 );

PS. Most likely you also have to add some conditions in there, so you don't change every link on your site and only the one you want to.
