Widget to display custom taxonomy tag cloud

Don’t know of any but you can easily create your own: <?php add_action(“widgets_init”, array(‘Widget_Custom_tax_tag_cloud’, ‘register’)); class Widget_Custom_tax_tag_cloud { function control(){ echo ‘No control panel’; } function widget($args){ echo $args[‘before_widget’]; echo $args[‘before_title’] . ‘Your widget title’ . $args[‘after_title’]; $cloud_args = array(‘taxonomy’ => ‘Your taxonomy here’); wp_tag_cloud( $cloud_args ); echo $args[‘after_widget’]; } function register(){ register_sidebar_widget(‘Widget name’, array(‘Widget_Custom_tax_tag_cloud’, … Read more

wp_insert_term doesn’t work with custom post type’s taxonomy

try init instead of after_setup_theme function example_insert_category() { wp_insert_term( ‘Example Category’, ‘friendsof’ ); } add_action( ‘init’, ‘example_insert_category’ );

Taxonomy terms sort by… Last name!

You can try the MySQL function SUBSTRING_INDEX() within the get_terms_orderby filter: /** * Order by the last word in the term name * @link https://wordpress.stackexchange.com/a/195039/26350 */ add_filter( ‘get_terms_orderby’, function( $orderby, $args ) { if( isset( $args[‘orderby’] ) && ‘wpse_last_word’ === $args[‘orderby’] ) $orderby = ” SUBSTRING_INDEX( t.name, ‘ ‘, -1 ) “; return $orderby; }, … Read more

Is there a way to disable a term rather than deleting it?

Not directly, but I have a need for this functionality as well, as part of a plugin I’m writing for a client and have what I think is a pretty good start on an implementation. The approach I’m taking is to store a term meta when the term is disabled and then to hook into … Read more

Query Custom Post Type taxonomy type based on page

To make that more efficient, instead of arguing the current page slug, you just place the current slug as the tax_query’s terms value. Something like: global $post; $args = array( ‘posts_per_page’ => -1, ‘post_type’ => ‘books’, ‘post_status’ => ‘publish’, ‘tax_query’ => array( array( ‘taxonomy’ => ‘book_category’, ‘field’ => ‘slug’, ‘terms’ => $post->post_name, // which’d be … Read more

How to group meta boxes on the post edit page

Thanks for the hint Bainternet, indeed this is very easy to implement with jQuery. Example (the four meta boxes are closed for clarity) : Here’s what I did : var $j = jQuery.noConflict(); $j(document).ready(function() { $j(“#side-sortables”).append(‘<div id=”container_div” class=”postbox meta-box-sortables ui-sortable”><div class=”handlediv” title=”Click to toggle.”><br></div><h3 class=”hndle”><span>Container Meta Box</span></h3><div id=”container_inside” class=”inside”></div></div>’); $j(“#my_metabox_div”).appendTo(“#container_inside”); $j(“#my_other_metabox_div”).appendTo(“#container_inside”); etc… }); I added … Read more

wp_set_object_terms() — prevent overwrite?

wp_set_object_terms() has a fourth argument called append. Setting that to true during the call should add the term without unsetting the already set terms. wp_set_object_terms( $post_id, ‘add_this_term’, ‘in_this_taxonomy’, true);

Custom Taxonomy Template Post List with Sort Order

The most efficient way is probably to hook into the pre_get_posts action and add your time comparison there. This way you don’t have to worry about the rest or the query options as they will still work. It should look like this (untested), and be placed in a plugin or theme functions file (not in … Read more

wp_set_object_terms() Fails to Set Terms

I don’t have a solution, but there’s a ticket #20541 on Make WordPress Core. Apparently a call to switch_to_blog() would not repopulate $wp_taxomies, which these taxonomies rely on.

wp_insert_term – parent & child problem

The issue is with the taxonomy cache. You have to clear it after you insert the terms in order to see them. I had the same issue, which someone answered for me here: delete_option(“classified-category_children”); Insert that after the term inserts and you should be good.
