Oh, I love it when you give me an easy one. Starts to make up for all those harder ones… (well, partly. 😉 So what you want is to replace this: (source: mikeschinkel.com) With this: (source: mikeschinkel.com) How? Use the ‘wp_tag_cloud’ hook which you can put into your theme’s functions.php file or in a .php … Read more
For each propery, ask yourself these questions: Is it likely that, on average, more than 1-2 posts will have the same value for this property? If so, do I need to filter posts based on this property, or is it just for display? If you answered both with ‘yes’, then make it a taxonomy, otherwise … Read more
Too much for a comment, so I’ll leave it for an answer: You’re asking a lot of Qs that should actually be different Qs and not dumped into a single one. (Ad 1.) You don’t register “child” or “parent” taxonomies. You add (child-)terms to a hierarchical taxonomy via the WP Back-End UI. You can do … Read more
As @shanebp suggests, you could use wp_count_terms() like this: $numTerms = wp_count_terms( ‘service-category’, array( ‘hide_empty’=> false, ‘parent’ => 0 ) ); The above will list All top parent terms, empty or not. This function uses get_terms() functions arguments which can be found in the link or the arguments below: $args = array( ‘orderby’ => ‘name’, … Read more
Add flush_rewrite_rules(); after your register taxonomies. That fixed it for me. Edit Do make sure you do it on install of your plugin if you’re using it on one. It should only be run once on pug-in activation – and not on every page load. Alternatively visit Settings > Permalinks page as this flushes the … Read more
When registering your taxonomy you can pass an argument called capabilities. Simply passing capabiities that only admins and editors have. $args = array( ‘capabilities’ => array( ‘manage_options’, ‘edit_posts’ ) ); register_taxonomy( ‘foobar’, ‘post’, $args ); https://codex.wordpress.org/Roles_and_Capabilities#Editor
This has nothing to do with custom taxonomies. I was using a snippet of code from the default ‘twentytwelve’ theme for image.php that was looping through every single post in the blog to get child attachments, and thus the taxonomy associations for each of those posts. Amending my image.php by removing this foreach() loop fixed … Read more
The register_taxonomy function is designed only for adding taxonomies to existing post types and custom post types. It’s not something that can be expanded to users. I have just tried a couple of plugins that work with taxonomies and neither are able to attach a taxonomy to a user. from http://codex.wordpress.org/Function_Reference/register_taxonomy : Usage <?php register_taxonomy( … Read more
If I understand your question correctly, I think I may have your answer in this blog post: https://evowebdev.com/2017/05/using-a-dropdown-menu-to-filter-a-custom-post-type-with-custom-taxonomy/ This solution specifically uses select form element auto-populated with taxonomy terms to sort CPT posts (ie, rather than presorting posts with pre_get_posts, it lets site visitors sort by the taxonomy term[s] they select). If it’s really important … Read more
For mutually exclusive values use post meta. It is faster to read than assigned taxonomies too. It is possible to create your own interface: Set the parameter show_ui to false when you register the taxonomy. Register a meta box where you print out all existing taxons with radio boxes. Add a save action to assign … Read more
