next_post_link/previous_post_link

  • Can anyone help me with some php here using these tags (and I gather they are new and not yet documented in the codex)

    I want to determine if there IS a next or previous post in the navigation. Because the functions echo – any test I perform automatically displays the content which makes it hard to test to see if anything is being returned. is there any other test I can perform that if TRUE then calls one of these tags?

    Thanks

  • next_post_link() and previous_post_link() are defined in /wp-includes/template-functions-links.php. The very first line of next_post_link() is:
    $post = get_next_post($in_same_cat, $excluded_categories);

    This is a common theme with WordPress template tags / functions: there are two functions that do the same thing. One returns the result(s) and the other outputs the result(s). The returning functions are usually named get_*.
    [Note: there are a few exceptions to this, but not many.]

    So, if you do:
    $post = get_next_post();
    if ($post) { // do stuff }
    you should be set.

    skippy – you’re a marvel. Now I know this snippet of structure it might resolve a few other tweaks.
    Thanks very much – I’ll try it right away.

    Actually… yes it does work.
    But then I notice that the Archive page uses a variant. next_posts_link which is a different routine and doesn’t appear to have the same option as you gave me for the single page query. Can you by any chance offer a solution for this one? I would have liked to style it the same way!
    Thanks

    While on the subject, the ‘plural’ version s used in Archive and Search templates are phrased the opposite way to the single page version. I.e., the ‘Next’ function actually reteurns ‘previous’ posts as far as date order goes…
