Why get_posts() not returning only selected category posts from Custom Post Type?

First, your custom post type is portfolio-item, not portfolio_item. Note that you register the post type with $this->base name and previously you did $this->base=”portfolio-item”;. Also, numberposts is obsolete, use post_per_page instead: $args = array( // ‘post_type’ => ‘portfolio_item’, ‘post_type’ => ‘portfolio-item’, ‘orderby’ => ‘rand’, ‘post_per_page’ => 1 ); Then, the taxomy argument of your query … Read more

Randomly Assign an Image’s Alt Text Based on Data From Post

Just set the image alt text when the image is saved. Hook onto the save_post action, check if any of the attached images don’t have alt text, and if not then generate the alt text you want and save it with: update_post_meta( $attachment_id, ‘_wp_attachment_image_alt’, ‘this is the alt text’ );

Meta description – template code to get category description

Is there a more “WordPress way” to do this… I don’t really know what you mean by a more WordPress way, but in general, the way you are getting the term description is a more reliable way in doing it. This way, you do not need to access the $post global which so many people … Read more

Query custom post type by custom taxonomy (category slug)

Edited to reflect question in OP’s comment. The contents of the tax_query array are not exactly right: as you’re querying by slug, the field parameter of the individual taxonomy query should be “slug”. You’re currently basically querying for all service posts from all service categories (well, not even that, because get_terms returns objects, but still). … Read more

Create a hierarchical taxonomy list in WordPress

You can use wp_list_categories() and pass in your custom taxonomy as an argument like so: $args = array( ‘taxonomy’ => ‘locations’, ‘orderby’ => ‘name’, ‘hide_empty’ => false, ‘show_count’ => false, ‘pad_counts’ => false, ‘hierarchical’ => true, ‘title_li’ => ” ); ?> <ul> <?php wp_list_categories( $args ); ?> </ul> https://developer.wordpress.org/reference/functions/wp_list_categories/

Catchable fatal error on custom category post

You can wrap it in the same check used for $category: <?php if (isset($term->term_id)) { echo ‘<a href=”‘.get_term_link($term).'”>’.$term->name.'</a>’; } ?> or check to make sure it is not an error object: <?php if (!is_wp_error($term)) { echo ‘<a href=”‘.get_term_link($term).'”>’.$term->name.'</a>’; } ?>

wp_get_post_terms on custom post type with custom taxonomies returning an empty array

Just change ‘fields’ => ‘name’ to ‘fields’ => ‘names’ If you look at the examples in wordpress documentation you can see you should use plural(names, slugs, ids for fields): https://codex.wordpress.org/Function_Reference/wp_get_post_terms#Examples

List child terms if parent but show nothing on children

For reliability, you can get the current term being viewed from the queried object from $GLOBALS[‘wp_the_query’] $current_term = sanitize_term( $GLOBALS[‘wp_the_query’]->get_queried_object() ); To answer your question, if Southern Africa is top level, it should have a parent term ID of 0. All child terms should have a numeric value as parent which corresponds to the parent … Read more

CPT UI change custom taxonomy url

You need to do this when you register your taxonomy in register_taxonomy() Pass the rewrite argument and customize to your needs: ‘rewrite’ => array(‘slug’ => ‘groceries/fruit’, ‘with_front’ => false) You’ll probably need to flush your permalinks in Settings as well.

What template files do I need to customise custom-category-term-links rather than fall back on archive.php?

Custom taxonomies have templates named taxonomy-something in this hierarchy: taxonomy-{taxonomy}-{term}.php taxonomy-{taxonomy}.php taxonomy.php archive.php index.php So, yes, if you have no taxonomy-custom-cat-term-cat.php, taxonomy-custom-cat.php or taxonomy.php then archive.php will be used. category-something.php will only be used for the built-in categories, if you are on a page showing posts from a category called “something.”
