Displaying Post Date with next_post() or previous_post()? (6 posts)

    The objective is to display the dates (if applicable) of the previous and next post, instead of using the post's title or something more ambiguous.

    « March 29 | March 31 »

    I've had a look into the codex and see that next_post() & previous_post() aren't setup to do as much.

    Suggestions on the best way to go about doing this?

    Cheers

    http://codex.wordpress.org/Template_Tags/next_post_link

    something like this:

    <?php previous_post_link('&laquo; %link', get_the_time('F j, Y',get_previous_post()->ID) ) ; ?> | <?php next_post_link('%link &raquo;', get_the_time('F j, Y',get_next_post()->ID) ) ; ?>

    This is pretty neat, but looks a little expensive to run (I'm going to have it at the top and bottom of each blog page).

    I came across an interesting article on get_adjacent_post here.

    Written out the long way for future searchers to understand, what about something like...

    $in_same_cat = false;
    $excluded_categories = '';
    $previous = true;
    $previous-post = get_adjacent_post($in_same_cat, $excluded_categories, $previous);

    And then pulling the necessary info out of the returned array (simplified example):
    echo $previous-post->post_date;

    this is another possible way; then you need to convert the raw output of $post_date; and get the permalink to wrap around it for the link ...
    probably not much saved.

    it would be interesting if you could run a few quantitative comparisons and report on the resources used by each method ;-)

    Indeed!

    Yeah, you'd still have to use build a lot of it out: ...the link (get_permalink($previous-post->ID)), convert the date, a sanitized post title for the anchor tag (if desired).

    I do like how I can keep all this in a variable though, for use again on the same page without querying all over again.

    Thanks for your thoughts!

    no problem to break the code into lines with variables; for 'prev' only:

    <?php
    $previous_post_id = get_previous_post()->ID;
    $previous_time = get_the_time($previous_post_is);
    $in_same_cat = false;
    $excluded_categories = '';
    previous_post_link('&laquo; %link', $previous_time, $in_same_cat, $excluded_categories );
    ?>

    probably not much difference in resources, certainly easier to understand, easier to comment for educational reasons, and better to edit in the future.
