If you are using the code inside a custom post type template, then the get_next_post() will get the next post for you. Then you can use the ->ID and get it’s ID. So: $next_post = get_next_post(); $next_post_id = $next_post->ID; If you need their link, simply use next_post_link() or previous_post_link(). These functions use the global post … Read more
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
Try this: function remove_link( $format, $link ) { return false; } add_filter( ‘previous_post_link’, ‘remove_link’ ); add_filter( ‘next_post_link’, ‘remove_link’ ); It should work if the theme uses next_post_link() and previous_post_link(). Cheers
Update: OK. If you get to keep changing the question, I get to delete what I had written before and start all over again. To be honest, I’m a bit confused about what you are trying to do. Since this appears to be for a single post (based on the comment at the top of … Read more
Find the solution: The hole snippet looks like this: <?php function filter_next_post_sort($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 $wpdb->prepare(“WHERE … Read more
Reviewing the MySQL string functions, it looks like you could use the SUBSTRING_INDEX() function: ORDER BY SUBSTRING_INDEX( p.post_title, ‘ ‘, -1 ) {ASC|DESC} LIMIT 1 to order by the last word of the post title. You could test this method within your orderby filters. Example: Prev/Next CPT – ordered by last word in post title … Read more
I don’t see a way to make the query faster, but we can cache the result. Unfortunately, there is no hook to circumvent next_post_link() and previous_post_link(), so we have to replace those functions with custom functions. The following sample code uses a post meta field to store the result. There might be side effects – … Read more
So in order to do this, I had to filter the SQL queries. I found this snippet that filters post order by title and returns them for next and previous post links. Unfortunately, this doesn’t work in a custom post type. So I replaced ‘post’ with get_post_type($post) to grab the current post type and return … Read more
