You’re assuming that get_terms() returns an object with a count property, but it doesn’t. From the docs: Return (WP_Term[]|int[]|string[]|string|WP_Error) Array of terms, a count thereof as a numeric string, or WP_Error if any of the taxonomies do not exist. See the function description for more information. Also, the way you’re calling get_terms() is deprecated. There … Read more
This code is certainly not perfect but it actually does the job : <?php // Store the current category ID : $current_object = get_queried_object_id(); // Get sticky post : $args = array( ‘posts_per_page’ => 1, ‘post__in’ => get_option( ‘sticky_posts’ ), ‘cat’ => $current_object, ‘ignore_sticky_posts’ => true, ); $sticky_query = new WP_query( $args ); // Get … Read more
Found the problem It was theme (Impreza) related (thank you @cjbj). When the blog post category was created, it created a loop via the theme: incorrect: correct:
Ok, I found a solution. By default in WP there is an option to filter categories by tags. E.g. https://example.com/category_name?tag=tag_name. I added a rewrite rule and redirection: https://developer.wordpress.org/reference/functions/add_rewrite_rule/ add_action( ‘init’, function () { add_rewrite_rule( ‘([a-z0-9-]+)\/tag\/([a-z0-9-]+)\/?$’, ‘index.php?category_name=$matches[1]&tag=$matches[2]’, ‘top’ ); } ); https://developer.wordpress.org/reference/hooks/template_redirect/ add_action( ‘template_redirect’, function () { if ( is_category() && is_tag() && ! empty( $_GET[‘tag’] … Read more
By default, get_categories() won’t return terms that have no posts (the hide_empty parameter is true). This should do it: $children = get_categories( array( ‘parent’ => 923, ‘hide_empty’ => false, ) );
There is number of functions that deal with categories. Some are meant to be used with other code and mostly deal with category objects, some are meant for displaying on front-end and outputting HTML. wp_list_categories() for example is meant for front-end presentation and defaults to hierarchical display.
Correct me if I’m wrong. I guess you use that code to custom display a category. If that’s the case, right before this code: <?php while (have_posts()) : the_post(); ?> You will need to add query_posts(): <?php query_posts(‘cat={categoryID}&paged=’ . $page); ?>
You should use <?php wp_dropdown_categories(); ?> http://codex.wordpress.org/Function_Reference/wp_dropdown_categories
You need to add &title_li= to your code like so to remove the word “Categories”: <?php wp_list_categories(‘orderby=id&show_count=0&use_desc_for_title=0&child_of=5&title_li=’); ?> More information on categories can be found in the codex here: http://codex.wordpress.org/Template_Tags/wp_list_categories
Look in your theme’s folder for a file called “category.php”. Open it then look for something like this: <span><a href=”https://wordpress.stackexchange.com/questions/7088/<?php the_permalink();?>”><?php the_title();?></a></span> Place this right below it: <p><?php the_excerpt();?></p> That will display an excerpt of each post below the title.
