You can insert an associative array into the post_meta_field. Here is a quick little function to grab the data afterward (did not test): function grab_task_name_array($post_id) { $new_array = array(); $array = get_post_meta($post_id,’_task-name’); //do not put true as third parameter (this would return string and not array) foreach($array[0] as $key => $value) $new_array[$key] = $value; return … Read more
There are plenty of functions for grabbing the data you need, a quick look at the Codex function reference reveals many useful functions you can use to build this. Use get_term_link to get the link to that terms archive, and wp_get_object_terms to get the terms of an object/post. To get all terms in a taxonomy … Read more
The filter you are looking for is term_links-$taxonomy, where $taxonomy is the taxonomy name. This will filter the $term_links links array before outputting by the_terms(): add_filter(‘term_links-cities’, ‘ad_filter_links’); function ad_filter_links($term_links) { foreach ($term_links as $term_link) { $term_link = str_replace(‘<a ‘, ‘<a class=”fancybox”‘, $term_link); } return $term_links; }

Register your taxonomies with ‘show_ui’ => false, and then add a single meta box to manage them. function create_book_tax() { register_taxonomy( ‘genre’, ‘book’, array( ‘label’ => __( ‘Genre’ ), ‘rewrite’ => array( ‘slug’ => ‘genre’ ), ‘hierarchical’ => true, ‘show_ui’ => false, ) ); } Or unhook the boxes from the side panel and put … Read more
It sounds like you are are using get_term() for a custom taxonomy. If you’re using get_term() inside functions.php and outside of a hooked function, that code is going to be run immediately when functions.php is loaded.
