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($post) to grab the current post type and return … Read more
this is very simple to do… // next function next_shortcode($atts) { // global $post; -unnecessary return ‘<div class=”nav-next”>’.next_post_link( ‘%link’, ‘%title <span class=”meta-nav”>’ . _x( ”, ‘Next post link’, ‘ ‘ ) . ‘</span>’,true ).'</div>’; } add_shortcode( ‘next’, ‘next_shortcode’ ); //prev function prev_shortcode($atts) { //global $post; -unnecessary return ‘<div class=”nav-previous”>’.next_post_link( ‘%link’, ‘%title <span class=”meta-nav”>’ . _x( … Read more
get_adjacent_post(), which is used by all functions that return a (link to) the next or previous post, only has a $in_same_cat argument, which looks at the categories the post is in, not the tags. You could hook into the get_[next|previous]_post_join to modify the join query for your call, but then it’s probably easier to copy … Read more
Update As I deleted the Repo on GitHub, here’s a new answer. add_filter( ‘previous_post_link”https://wordpress.stackexchange.com/questions/13044/,”wpse13044_adjacent_post_link_tooltip’, 10, 2 ); add_filter( ‘next_post_link”https://wordpress.stackexchange.com/questions/13044/,”wpse13044_adjacent_post_link_tooltip’, 10, 2 ); function wpse13044_adjacent_post_link_tooltip( $format, $link ) { $previous=”previous_post_link” === current_filter(); // Get the next/previous post object $post = get_adjacent_post( false ,” ,$previous ); // Copypasta from cores `get_adjacent_post_link()` fn ” === $title = get_the_title( … Read more
I managed to get this working using nothing but WordPress filters, thanks to @Milo’s hint. Just note that these are pretty specific to my case but you shouldn’t have a problem modifying them for your own use. I am using Advanced Custom Fields with a Date Picker field called date and Prev/Next links only point … Read more
Take a look at get_previous_post() and get_next_post() and you’ll see they both use the get_adjacent_post() to find the previous or next post. Let’s say you want to fetch the ID of the immediately previous post based on the current post’s ID. This is what you’d do: function get_previous_post_id( $post_id ) { // Get a global … Read more
try to work with http://codex.wordpress.org/Function_Reference/get_adjacent_post; example: $next_post_link_url = get_permalink( get_adjacent_post(false,”,false)->ID ); $prev_post_link_url = get_permalink( get_adjacent_post(false,”,true)->ID );
Understanding the internals The “sort” order of adjacent (next/prev) posts is not really a sort “order”. It’s a separate query on each request/page, but it sorts the query by the post_date – or the post parent if you have a hierarchical post as currently displayed object. When you take a look at the internals of … Read more
