I believe you are using the following code from this pastebin link function posts_by_year() { // array to use for results $years = array(); // get posts from WP $posts = get_posts(array( ‘numberposts’ => -1, ‘orderby’ => ‘post_date’, ‘order’ => ‘ASC’, ‘post_type’ => ‘my-custom-post-type’, ‘post_status’ => ‘publish’ )); // loop through posts, populating $years arrays … Read more
From what I can tell, this stems from your use of get_post_field(), which is reserved for fields found in the posts table of the database (ie: built-in to WordPress, rather than custom fields). For custom fields you should use get_post_meta().
Assuming you have a list containing the post IDs you want to exclude, you could start with something like (PHP 7.3): function exclude_posts_from_category( array $cat_args ): array { $exclude = array(); // TODO Add post IDs to exclude. $cat_args[‘exclude’] = $exclude; return $cat_args; } add_filter( ‘widget_categories_args’, ‘exclude_posts_from_category’, 10, 1 ); You can read about the … Read more
As far a I can understand you need to display the category name for the current page when viewing a category page. You can make use of the query variables to retrieve the category name, for example: $category = get_queried_object(‘cat’); echo $category->name; EDIT A global check to see what is returned by the main query … Read more
May be easier to just work with it, than against it… Instead of: $cat_id = sanitize_text_field($_POST[‘cat’]); Try: $cat_name = sanitize_text_field( $_POST[‘cat’] ); $cat = get_term_by( ‘name’, $cat_name, ‘category’ ); $cat_id = $cat->term_id;
Try using has_term(). Something like this: <?php if( has_term(‘term1’, ‘taxonomy_name’, $post) ) { ?> <img src=”http://www.site.com/wp-content/themes/site/img/stars-01.png” width=”100″ height=”21″ alt=”default”> <?php }elseif ( has_term( ‘term2’, ‘taxonomy_name’, $post) ) { ?> <img src=”http://www.site.com/wp-content/themes/site/img/stars-01.png” width=”100″ height=”21″ alt=”default”> <?php } else { ?> <img src=”http://www.site.com/wp-content/themes/site/img/stars-01.png” width=”100″ height=”21″ alt=”default”> <?php } ?> You may also want to try using shorthand … Read more
I found the correct syntax is: if ( is_single() && in_category ( ‘5’ ) ) { However, I solved the problem using this code: //add category classes to single.php add_filter(‘body_class’,’add_category_to_single’); function add_category_to_single($classes, $class) { if (is_single() ) { global $post; foreach((get_the_category($post->ID)) as $category) { // add category slug to the $classes array $classes[] = $category->category_nicename; … Read more
wp_terms_checklist() is an admin side function as you suspect. I don’t recommend trying to load admin side code on the front end (especially if you are not very very familiar with its inner workings) so essentially you are left with rolling your own code to create the checklist. You should be able to use the … Read more
This is how its done in Twenty Fourteen which uses a template tag: Note: The conditionals if ( is_sticky() && is_home() && ! is_paged() ) { will need to be changed or removed if ( ! function_exists( ‘twentyfourteen_posted_on’ ) ) : /** * Print HTML with meta information for the current post-date/time and author. * … Read more
