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.
taxonomy
get a specific taxonomy term name
Use get_term() to get the name, slug, or description: $term = get_term( 1, ‘taxonomy_slug’ ); // Name echo $term->name; // Link echo get_term_link(1, ‘taxonomy_slug’); // OR echo get_term_link( $term );
Using pre_get_posts to set posts per page, how do I?
You’re almost there mate. Try this though. <?php add_action(‘pre_get_posts’, ‘filter_press_tax’); function filter_press_tax( $query ){ if( $query->is_tax(‘press’) && $query->has_term(‘press’)): $query->set(‘posts_per_page’, 5); return; endif; } ?> You can use any conditional tag or any argument that can be passed to WP_Query to test your condition or set a new value via pre_get_posts. Also try $query->get(‘taxonomy’) / $query->get(‘term’). … Read more
How to organize and cache additional data associated with terms?
I’d say your third option is the way to go. Incidentally, why did you roll your own static cache in taxonomy_image_plugin_get_associations() instead of using the built-in WP_Cache API for that? Is there a reason wp_cache_get wouldn’t work here? Seems like using the WP object cache would optimize better when people do have caching plugins turned … Read more
get term by id without taxonomy
Yes, but you need you make your own SQL query. A modified version of WP’s get_term(): function &get_term_by_id_only($term, $output = OBJECT, $filter=”raw”) { global $wpdb; $null = null; if ( empty($term) ) { $error = new WP_Error(‘invalid_term’, __(‘Empty Term’)); return $error; } if ( is_object($term) && empty($term->filter) ) { wp_cache_add($term->term_id, $term, ‘my_custom_queries’); $_term = $term; … Read more
Automatically Assign Parent Terms When A Child Term is Selected
Hooking into save_post action. add_action(‘save_post’, ‘assign_parent_terms’, 10, 2); function assign_parent_terms($post_id, $post){ if($post->post_type != ‘product’) return $post_id; // get all assigned terms $terms = wp_get_post_terms($post_id, ‘product_cat’ ); foreach($terms as $term){ while($term->parent != 0 && !has_term( $term->parent, ‘product_cat’, $post )){ // move upward until we get to 0 level terms wp_set_post_terms($post_id, array($term->parent), ‘product_cat’, true); $term = get_term($term->parent, … Read more
What is wp_insert_term “alias_of” arg for?
In the Code Reference it says: ‘alias_of’ (string) Slug of the term to make this term an alias of. Default empty string. Accepts a term slug. This makes a term an alias of another term. Using your example this is how you would use it: wp_insert_term( ‘e’, ‘tax’, array( ‘alias_of’ => ‘a’ ) ); This … Read more
tax_query in get_posts() not working?
tax_query takes an array of tax query arguments arrays (it takes an array of arrays) but you are using only single array. The correct code is as following. $uposts = get_posts( array( ‘post_type’ => ‘product’, ‘numberposts’ => -1, ‘tax_query’ => array( array( ‘taxonomy’ => $cat->taxonomy, ‘field’ => ‘slug’, ‘terms’ => array($cat->slug), ‘operator’ => ‘IN’, ) … Read more
How does Woocommerce store variation attributes, and how can they be retrieved per-variation? [closed]
Attributes are stored on wp_term_relationships. Ex: +————–+——————-+——————-+ | object_id | term_taxonomy_id | term_taxonomy_id | +————–+——————-+——————-+ | 91 | 48 | 0 | +————–+——————-+——————-+ Product 91 has an attribute 48
Why does get_term() require taxonomy? Are term_ids not unique?
I’ve logged a ticket against this with trac: http://core.trac.wordpress.org/ticket/20536 However, it turns out that for the time being it IS necessary, as WordPress currently (since 2.x) has a bug that DOES associate two terms with the same name to the same term_id! So it IS possible (though incorrect) for a single term to be associated … Read more
