I don’t see this as excessively heavy. Just use is_user_logged_in() and current_user_can(). Obviously if user isn’t logged in then you can skip checking for any roles. I am not sure, but user data is probably held in memory so there will be no extra database calls and such.
In the case of custom fields- if you fetch them in a single query to the database, fetching one or ten is not going to differ much, it’s the same relatively simple query in both instances. If you were to do a lot of complex meta queries on those fields you’d definitely see a performance … Read more
You need to take a look at /core_root/wp-admin/includes/class-wp-terms-list-table.php and then add an extended class and make use of the WP_list_Table Class and documentation. basically you’re overriding the order and orderby in some custom plugin. Btw: “No Plugins” is never a good idea as plugins may show you how it works in code and therefore be … Read more
There is no default rewrite to a template for a category or taxonomy landing page. You are correct, that this can be done by creating a custom template and applying it to a page.
The easiest way would be to use a function which accepts a region taxonomy term as an argument, and outputs a list of posts with that term (i.e. ‘in that region’). So your template looks like: <!–nw–> <div id=”nw” class=”counties-container”> <h2>North West</h2> <p class=”nw-t”><?php my_posts_by_region(‘nw’); ?></p> </div> I’m assuming that ‘nw’ is the term name … Read more
You are using wp_set_object_terms wrong, the second parameter should be the term slug or id and the 3 parameter should be the taxonomy name, so try: function set_default_object_terms( $id, $post ) { if ( ‘publish’ === $post->post_status ) { log_me (‘be in function while “publish” i pressed with this id: ‘.$id); $taxonomy_ar = get_terms( ‘property-features’ … Read more
Just looking at the term_taxonomy table, you are selecting everything correctly, but the last part: WHERE $wpdb->posts.post_type=”publications” AND $wpdb->terms.slug = %s AND $wpdb->term_taxonomy.taxonomy = ‘category’ ORDER BY $wpdb->term_taxonomy.taxonomy = ‘topics’ DESC from the post_type of publications, the terms slug of %s, and has the taxonomy of categories, but you are never selecting the taxonomy topics. … Read more
Here’s part of the answer… how to query for the terms you’re looking for. But it sounds like you’ll need some ajax to re-query for each selection. City and cuisine would be dynamic, but essentially the when the user selects the city populate that data into the $city variable, and so on. Someone else will … Read more
I encountered a very similar situation, and I believe it may very well be the same situation you are experiencing. Please read the WPSE question Programmatically insert hierarchical terms & set terms for post causes glitch? and follow up with the answer provided by @Manny Fleurmond.
Why not use a hierarchical taxonomy? I can’t think of a better use for hierarchy than what you are describing. As far as your perceived disadvantages: Admin needs to select all applicable classification parts when associating to a plant (eg; a family, a genus and a species) Rhamnaceae – Ziziphus — Ziziphus Jujuba If you … Read more
