You can do this by using previous_post_link() and next_post_link(). These functions will create the links for you, and you should be able to get rid of all of the logic you are using for pagination. As you wish to only link to posts in the same category you should use the functions with the following … Read more
It makes perfect sense, but kind of backwards. I think the query that is executed to “exclude” posts from categories is grabbing all of the categories (this may return category IDs 1, 2, 5, 7, 11, 13, 15, 16, and 23) initially then checking the “exclude_category” param (“11 and 13 and 15”) and running the … Read more
<?php next_post_link(‘format’, ‘link’, ‘in_same_cat’, ‘excluded_categories’); ?> <?php previous_post_link($format, $link, $in_same_cat = false, $excluded_categories=””); ?>
previous_post_link() and next_post_link() work perfectly with custom post types. You need to paste this code in your single-customposttype.php (which in your case is single-portfolio.php): <div class=”previous-post-link”> <?php previous_post_link(‘%link’, ‘<< Previous Post’, $in_same_term = true, $excluded_terms=””, $taxonomy = ‘the-custom-taxonomy-associated-with-your-custom-post-type’); ?> </div> <div class=”next-post-link”> <?php next_post_link(‘%link’, ‘Next Post >>’, $in_same_term = true, $excluded_terms=””, $taxonomy = ‘the-custom-taxonomy-associated-with-your-custom-post-type’); ?> … Read more
“Inside the Loop” essentially means that function relies on data from global variables (such as $post) that are set up when Loop runs. Note that this is not necessarily done by main Loop of query_posts(). In your specific code those variables are filled by $custom_posts->the_post() calls and after that wp_reset_query() gets those values back to … Read more
To get next/prev posts, usually all you need is to se to true the parameter that indicates that next/prev post should be in the same taxonomy term in the get next/prev post functions, you don’t need to deal with any filter. For example: To get next and prev post objects: // First parameter for these … Read more
Update: OK. If you get to keep changing the question, I get to delete what I had written before and start all over again. To be honest, I’m a bit confused about what you are trying to do. Since this appears to be for a single post (based on the comment at the top of … Read more
First of all I suggest you to use a function to return the terms to exclude, that will help you to get them in different places without having to repeat code, e.g. in the ‘pre_get_posts’ filter and the adjacent post filters. So: function get_level_term_to_exclude() { if ( current_user_can (‘manage_options’) || current_user_can (‘view_level1_posts’) ) { return … Read more
So in order to do this, I had to filter the SQL queries. I found this snippet that filters post order by title and returns them for next and previous post links. Unfortunately, this doesn’t work in a custom post type. So I replaced ‘post’ with get_post_type($post) to grab the current post type and return … Read more
