Let's say I have the posts foo, bar and baz. They are published in the following order:

1. foo
2. bar
3. baz

If I call get_previous_post() while on the single.php of baz, I'll get bar.


I set bar as sticky. Now, the posts are ordered like so:

2. bar
1. foo
3. baz

If I call get_previous_post() while viewing baz, I still get bar, because it's chronologically the previous post. However, in the actual "loop display" of the posts, foo is previous.

Question

How do I get the "visually previous" post in WordPress?

Edit: Basically, I want get_previous_post() to process sticky posts as the newest, regardless of their post date.

  • So to make this clear: You are inside (the loop / a specific post) - meaning get_post() will return the viewed post - and want the first previous/next post that is not a sticky? Actually seems a bit complicated, as get_adjacent_post() doesn't take post ID into account, so you can't call it that easily on another post beside the current one ... – kero Jul 8 '17 at 11:56
  • I have a listing on my index.php as described in my question. When I'm on the single.php of a post, I want to get the previous post as seen on the listing. – Hristiyan Dodov Jul 8 '17 at 12:07

Ok, this might be overcomplicating things a bit, but at least it should work (untested).

Just call the function like so

get_adjacent_without_sticky( get_the_ID(), true); // get previous post
get_adjacent_without_sticky( get_the_ID(), false); // get next post

This could have been solved easily, if get_previous_post() allowed for an ID to pass and not only run it in the context of the current post. Now you could copy the function code of get_adjacent_post() and adjust it to your needs, but I don't like messing directly with SQL inside WordPress, so using the common functions it should work like this:

function get_adjacent_without_sticky($id, $previous = true) {

    // get date of current post as reference
    $date = explode('.', get_the_date('d.m.Y', $id));
    $date_array = array(
        'day' => $date[0],
        'month' => $date[1],
        'year' => $date[2],
    );

    // for previous post we need the first post before current one
    if ($previous) {
        $order = 'DESC';
        $date_query = array(
            'before' => $date_array,
        );
    }
    // for next post we need the first post after current one
    else {
        $order = 'ASC';
        $date_query = array(
            'after' => $date_array,
        );
    }

    $args = array(
        // order sticky posts as regular ones
        'ignore_sticky_posts' => 1,
        // get only the one post we want
        'posts_per_page' => 1,
        'order' => $order,
        'orderby' => 'date',
        'date_query' => $date_query,
    );

    // now run that query
    $the_query = new WP_Query($args);
    if ($the_query->have_posts()) {
        $the_query->the_post();
        $result = get_post( get_the_ID() );
    } else {
        $result = NULL;
    }
    wp_reset_postdata(); // Restore original Post Data

    return $result;
}

(My answer is bascially these two sources combined into a function.)

  • Actually, I want to have sticky posts. I simply want to display the previous post as seen on the listing. By default, get_previous_post() returns the chronologically previous post. It doesn't care whether the post is sticky or not. I think this would explain it best: If I set the oldest post as sticky, I want get_previous_post() to process it as the newest. – Hristiyan Dodov Jul 8 '17 at 12:31
  • Okay, sorry. Then simply removing 'post__not_in' => $sticky, should work, because ignore_sticky_posts will make them sorted regularly – kero Jul 8 '17 at 12:45
