To get next/prev posts, usually all you need is to se to true the parameter that indicates that next/prev post should be in the same taxonomy term in the get next/prev post functions, you don’t need to deal with any filter. For example: To get next and prev post objects: // First parameter for these … Read more
Building on Bainternet’s answer above, but making it more generic, I wrote this quick plugin. You can probably modify the link building function at the bottom to do what you want more exactly. <?php /* Plugin Name: Search Context Description: Use search context on single post pages when they’re reached from a search results page … Read more
Here’s a little coding that should implement this for you: <?php $max_length = 5; // set max character length here $next = get_next_post()->ID; $prev = get_previous_post()->ID; if( $prev ) { $title = get_the_title( $prev ); $link = get_the_permalink( $prev ); $post_name = mb_strlen( $title ) > $max_length ? mb_substr( $title, 0, $max_length ) . ‘ … Read more
Update: OK. If you get to keep changing the question, I get to delete what I had written before and start all over again. To be honest, I’m a bit confused about what you are trying to do. Since this appears to be for a single post (based on the comment at the top of … Read more
Find the solution: The hole snippet looks like this: <?php function filter_next_post_sort($sort) { global $post; if (get_post_type($post) == ‘MyCustomPostType’) { $sort = “ORDER BY p.post_title ASC LIMIT 1”; } else{ $sort = “ORDER BY p.post_date ASC LIMIT 1”; } return $sort; } function filter_next_post_where($where) { global $post, $wpdb; if (get_post_type($post) == ‘MyCustomPostType’) { return $wpdb->prepare(“WHERE … Read more
Reviewing the MySQL string functions, it looks like you could use the SUBSTRING_INDEX() function: ORDER BY SUBSTRING_INDEX( p.post_title, ‘ ‘, -1 ) {ASC|DESC} LIMIT 1 to order by the last word of the post title. You could test this method within your orderby filters. Example: Prev/Next CPT – ordered by last word in post title … Read more
All right, here it is, fully working: <?php $pagelist = get_pages(“child_of=”.$post->post_parent.”&parent=”.$post->post_parent.”&sort_column=menu_order&sort_order=asc”); $pages = array(); foreach ($pagelist as $page) { $pages[] += $page->ID; } $current = array_search($post->ID, $pages); $prevID = $pages[$current-1]; $nextID = $pages[$current+1]; ?> <div class=”navigation”> <?php if (!empty($prevID)) { ?> <div class=”previous”> <a href=”https://wordpress.stackexchange.com/questions/54422/<?php echo get_permalink($prevID); ?>” title=”<?php echo get_the_title($prevID); ?>”>Previous</a> </div> <?php } … Read more
First of all I suggest you to use a function to return the terms to exclude, that will help you to get them in different places without having to repeat code, e.g. in the ‘pre_get_posts’ filter and the adjacent post filters. So: function get_level_term_to_exclude() { if ( current_user_can (‘manage_options’) || current_user_can (‘view_level1_posts’) ) { return … Read more
I don’t see a way to make the query faster, but we can cache the result. Unfortunately, there is no hook to circumvent next_post_link() and previous_post_link(), so we have to replace those functions with custom functions. The following sample code uses a post meta field to store the result. There might be side effects – … Read more
So in order to do this, I had to filter the SQL queries. I found this snippet that filters post order by title and returns them for next and previous post links. Unfortunately, this doesn’t work in a custom post type. So I replaced ‘post’ with get_post_type($post) to grab the current post type and return … Read more
