If you want to query for a large set of posts, but don’t need full information for each you can use ‘fields’ => ‘ids’m see Return Fields Parameter. In this case, I concur with comment, it might make more sense to simply retrieve adjacent post several times. You’ll have to use setup_postdata() and wp_reset_postdata() since … Read more
You can do this by using the get_{$adjacent}_post_where filter. Basically all we are doing is replacing the part of the query that says “find published posts” with “find published or future posts”. /** * Amend the ‘WHERE’ clause in the SQL query to find an adjacent post * * @param required string $where The default … Read more
Harman, don’t use get_posts() when pagination is required. You may also accomplish this task using WP_Query. Refer to this answer explained beautifully by Chip Bennett at How to fix pagination for custom loops? <?php $user_fav = get_user_favorites($user_id); $paged = ( get_query_var( ‘paged’ ) ) ? get_query_var( ‘paged’ ) : 1; $args = array( ‘posts_per_page’ => … Read more
If you have a look at what next_post_link you’ll see that it takes a parameter $link as the second argument: next_post_link( $format, $link, $in_same_term = false, $excluded_terms=””, $taxonomy = ‘category’ ); Your parameter for this currently doesn’t include the post thumbnail: _x( ‘%title <span class=”meta-nav”>→</span>’, ‘Next post link’, ‘nicosite’ ) So we need to add … Read more
previous_image_link looks like it uses adjacent_image_link. You can probably do more with the post ID. This example shows how to get the previous and next post, then gets any image data out of the post thumbnail. While this doesn’t directly answer your question but I’m pretty confident you can use the ID to get what … Read more
Unfortunately, your logic doesn’t quite work out. The reason is because the order of operations, just like math, works inside to outside. So, your short_title() function is running with just passing the string %title, which then returns, I assume, the same string because that string meets your requirements. Then it passes %title onto previous_post_link and … Read more
Use the_post_navigation( $args ); to display next and previous links in your template for a single post. To restrict links to the same category, your $args array, in its simplest form, should be: $args = array( ‘in_same_term’ => true, ); Other parameters are optional. Get their list here.
I made some updates in your code. Please, try this updated version. <div id=”demo”> <?php $wp_query = new WP_Query( array( ‘category_name’ => ‘Case Study’, ‘posts_per_page’ => 1, )); ?> <?php if ( $wp_query->have_posts() ) : ?> <?php while ( $wp_query->have_posts() ) : the_post(); ?> <?php the_title(); ?> <?php the_content(); ?> <?php endwhile; ?> <div class=”nav-previous … Read more
When in_same_term parameter in get_next_post() / get_previous_post() function is set to TRUE, a post is selected from any category assigned to the current post. As you wrote, you can not use the exclude parameter in this case. Using the get_{$adjacent}_post_where filter, you can skip product in the category list, which you are looking for posts. … Read more
get_next_post returns null if there is no post anymore. And then get_permalink will have a null value for $next_post, so it will get the permalink for the current post, resulting in linking to the same post again and again. You should thus check for null, and if so, link to the first (latest) post. Something … Read more
