I am designing a theme where the home page (i.e.
is_home()) should only display the latest blog post. I want to do something like
$wp_query->update_option('posts_per_page', 1) every time I am on the home page. All other pages that display posts (like archives) should just follow the user defined option.
This seems a bit unnecessary to do every single time since the option should just be set once, right? Is it possible within The Loop to just ignore the user-set option of
posts_per_page and force
have_posts() to just be set to one post?
In general, where should this kind of "set-it-once" stuff go? I don't really think it should be a plug-in because it is theme specific. I also don't want to mess with the user's options which is why
update_option isn't the best choice for this problem.
