As I previously said in a comment You are using invalid values in get_previous_post() and get_next_post(). You are better of here writing your own function I came up with the following. : Get an array of all the posts and determine the current post’s position. Get the post ID’s of the posts on both sides … Read more
@Milo solved this one – It was because the posts were imported using an import plugin hence having all the same date bar a few that ticked over every second! All posts must have a unique date / time in order for next and prev links to work.
You want to change the in_same_term value to TRUE as follows: function crunchify_post_navigation(){ ?> <div class=”arrowNav”> <div class=”arrowLeft”> <?php previous_post_link(‘%link’, ‘↞’, TRUE); ?> </div> <div class=”arrowRight”> <?php next_post_link(‘%link’, ‘↠’, TRUE); ?> </div> </div> <?php } add_action(‘wp_footer’, ‘crunchify_post_navigation’);
OK, so there’s a problem with Codes in this part, I guess. The Codex article on Next and Previous Links contradicts the article specifically on next_post_link() In that article you can clearly see, that it looked a little bit different. In the part describing next_post_link there is a note: Deprecated: previous_post() and next_post(). Use: –> … Read more
Take a look at the get_adjacent_post function. It takes three paramters, all of which are optional: a boolean, whether the post should be from the same category a string of category IDs that should be excluded a boolean, whether the previous (true) or next (false) post should be retrieved. Hence the previous post, regardless of … Read more
This seems to do the trick: add_filter( ‘next_post_link’, ‘wpse_post_link’, 10, 4 ); add_filter( ‘previous_post_link’, ‘wpse_post_link’, 10, 4 ); function wpse_post_link( $output, $format, $link, $post ) { if( $url = get_permalink( $post ) ) $output = str_replace( $url, $url . ‘#anchor’, $output ); return $output; } i.e. appending the #anchor to the previous/next permalinks. ps: I … Read more
What you call “slugs” here is more appropriately called terms. It is a little confusing with native taxonomies because it turns into tautology: individual categories are terms of the category taxonomy. So sports and tech are terms of native category taxonomy. The function arguments operate on taxonomy level, not term level. That is you need … Read more
The function behind the function behind the function… next_post_link(); is a wrapper for adjacent_post_link(); which then calls get_adjacent_post(); where the 3rd argument is $previous and set to true/false to get the previous or next post. This gives you two opportunities: Use the output or the query filter. Output filter This might sound easier, but you’ll … Read more
next_posts_link and previous_posts_link (plural) are for archive pagination. For single posts you want next_post_link and previous_post_link (singular).
You can use get_adjacent_post function for retrieving that data. This function retrieve adjacent post. Can either be next or previous post. For previous post <?php $prevpost = get_adjacent_post( false, ”, true, ‘category’ ); $image = get_the_post_thumbnail( $prevpost ); $name = get_the_title( $prevpost ); $url = get_permalink( $prevpost ); ?> For next post <?php $nextpost = … Read more
