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
URL structure and data storage are separate issues. You can use any data in an URL, so let’s ignore that part for now. Next step: By naming the parts sub and sub sub you went into the wrong direction. Just focus on what the information is, not where it belongs. Data objects City should probably … Read more
Any tax_query can take an include_children argument (see Codex) that defaults to true. So just add that to your code and it should work: <?php $args = array( ‘posts_per_page’ => 100, ‘post_status’ => ‘publish’, ‘tax_query’ => array( array( ‘taxonomy’ => ‘ait-dir-item-category’, ‘field’ => ‘id’, ‘terms’ => 75, ‘include_children’ => false ) ), ‘post_type’ => ‘ait-dir-item’ … Read more
I managed to work it out. Seems like the filters only work when wrapped in an ‘admin_init’ action. My final code to add an admin column for the custom taxonomy meta ‘front_page’ to the custom taxonomy ‘shopp_department’ in my themes’ functions.php // Register the column function department_add_dynamic_hooks() { $taxonomy = ‘shopp_department’; add_filter( ‘manage_’ . $taxonomy … Read more
I came up with this with the add_rewrite_rule(): add_rewrite_rule(‘^recipes-with-([^/]*)/?’,’index.php?ingredient=$matches[1]’,’top’); I did some testing for the above, and it works well when you use it for one taxonomy at time. Here is the code from my functions.php: add_action( ‘init’, ‘create_ingredient_tax’ ); function create_ingredient_tax() { register_taxonomy( ‘ingredient’, ‘post’, array( ‘label’ => ‘Ingredient’, ‘hierarchical’ => true ), array( … Read more
I am not sure why your taxonomy-my-taxonomy-my-term.php is not working… If you want all of the terms of the custom taxonomy to have the same layout use taxonomy-my-taxonomy.php. If you want all of your custom taxonomies to be displayed in the same way you could even use taxonomy.php. In case you haven’t done yet, check … Read more
The only really interesting (and very important) part of the 3rd query is this: ‘project_location_children’, ‘a:7:{i:22;a:1:{i:0;i:23;}…etc…}}’ The a:n:{i:n; etc } stuff is a serialized PHP array. WordPress – for some historical reason – keeps track of term children in one option entry per taxonomy term. The painful thing is, that a lot of people don’t … Read more
Ok, I found the plugin “Better Internal Link Search” and this does the job!
