The arguments for get_adjacent_post is not formatted correctly. $excluded_terms needs to be either a string or an array. Also be careful with the category. If ‘portcats’ is a category name and not a taxonomy, that won’t work. This is looking for posts that are in the same ‘portcats’ taxomony with certain terms in ‘portcats’ excluded. … Read more
There is no way to do this natively, so you will need to do this by custom functions. Here is what you will need to do: (This complete solution is based on the build-in taxonomy, category) You will need to implement a system whereby you will need to determine the current post position of the … Read more
If you want to query for a large set of posts, but don’t need full information for each you can use ‘fields’ => ‘ids’m see Return Fields Parameter. In this case, I concur with comment, it might make more sense to simply retrieve adjacent post several times. You’ll have to use setup_postdata() and wp_reset_postdata() since … Read more
get_next_posts_link() won’t work in is_single() context – see source – and is intended for paged content. For the is_single() context use next_post_link() and previous_post_link() to echo the output. Or to return the output get_next_post_link() and get_previous_post_link().
You can do this by using the get_{$adjacent}_post_where filter. Basically all we are doing is replacing the part of the query that says “find published posts” with “find published or future posts”. /** * Amend the ‘WHERE’ clause in the SQL query to find an adjacent post * * @param required string $where The default … Read more
Harman, don’t use get_posts() when pagination is required. You may also accomplish this task using WP_Query. Refer to this answer explained beautifully by Chip Bennett at How to fix pagination for custom loops? <?php $user_fav = get_user_favorites($user_id); $paged = ( get_query_var( ‘paged’ ) ) ? get_query_var( ‘paged’ ) : 1; $args = array( ‘posts_per_page’ => … Read more
If you have a look at what next_post_link you’ll see that it takes a parameter $link as the second argument: next_post_link( $format, $link, $in_same_term = false, $excluded_terms=””, $taxonomy = ‘category’ ); Your parameter for this currently doesn’t include the post thumbnail: _x( ‘%title <span class=”meta-nav”>→</span>’, ‘Next post link’, ‘nicosite’ ) So we need to add … Read more
previous_image_link looks like it uses adjacent_image_link. You can probably do more with the post ID. This example shows how to get the previous and next post, then gets any image data out of the post thumbnail. While this doesn’t directly answer your question but I’m pretty confident you can use the ID to get what … Read more
Unfortunately, your logic doesn’t quite work out. The reason is because the order of operations, just like math, works inside to outside. So, your short_title() function is running with just passing the string %title, which then returns, I assume, the same string because that string meets your requirements. Then it passes %title onto previous_post_link and … Read more
Use the_post_navigation( $args ); to display next and previous links in your template for a single post. To restrict links to the same category, your $args array, in its simplest form, should be: $args = array( ‘in_same_term’ => true, ); Other parameters are optional. Get their list here.
