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
Something like this should work for your single.php template: <?php $next_post = get_adjacent_post( false,”,false ); if( isset($next_post->ID) ): $next_id = $next_post->ID; else: $next_post = new WP_Query( ‘posts_per_page=1&post_type=photo&order=ASC’ ); $next_id = $next_post->post->ID; endif; ?> <a href=”https://wordpress.stackexchange.com/questions/27977/<?php echo get_permalink( $next_id ); ?>”> <?php echo get_the_post_thumbnail( $next_id, ‘thumbnail’ ); ?> </a>
When using custom post types I got around this problem by using the following code. Of course you will need to put in the HTML for how you want it to display on your site. <?php $temp = $wp_query; $wp_query= null; $wp_query = new WP_Query(); $wp_query->query(”); // Enter you query here ?> <?php while ($wp_query->have_posts()) … Read more
Don’t use query_posts! As Eugene pointed out, you omitted the paged variable. However, even with that in you can get unexpected behaviour. As illustrated by the various questions we get on query_posts and pagination: query_posts and pagination, still stuck after much research Pagination throws 404 Pagination throws 404 error on custom taxonomy archive pages
That should be default behavior, provided that the checkbox of the parent category was checked. From the codex: “If the post is in both the parent and subcategory, or more than one category, the next post link will lead to the next post in any of those categories.”
I’m not familiar with Genesis, but I assume you can wrap the output of your function in a check if is_single(): function custom_post_navigation() { if( is_single() ) { // output next/prev links } }
Check the published date/time for the skipped posts. You will run into problems with posts published at the same time as the current post’s publish time.
Ok, So, this is a two part question, part #1: What I would like to do is count the number of posts in a category and use the next_post_link and previous_post_link link to navigate through them, then display a count. What I did to fix this issue was install the Smarter Navigation plugin Then use … Read more
The function next_post_link() allow excludes, with the parameter excluded_terms. Add a list of the IDs of the password protected posts to this param. You get a list of all password protected posts with the follow example via DB select. $password_pages = $wpdb->get_col(“SELECT ID FROM $wpdb->posts WHERE post_status=”publish” AND post_type=”post” AND post_password !=””); Alternative can you … Read more
