I found the solution thanks to answer this question: Specify number of posts in my ‘tax_query’ I wanted to show the posts for ‘futbol’ within the ‘tipo_deporte’ taxonomy: <?php $args = array( ‘posts_per_page’ => 2, ‘tax_query’ => array( array( ‘taxonomy’ => ‘tipo_deporte’, ‘field’ => ‘slug’, ‘terms’ => array(‘futbol’), ) ) ); $query = new WP_Query( … Read more
I finally found the solution to delete all the postmeta related to the term being deleted. For this, we need to use the action hook ‘delete_term_taxonomy’ because it is executed before the term is deleted; therefore, we can find the term object and use it inside the hook. Then, we proceed to perform certain task … Read more
According to WPSeek’s page on the create_{$taxonomy} action hook, and also the new-to-me WordPress Developers’ docs on the same hook, there are two required parameters: Parameters $term_id (int) (Required) Term ID. $tt_id (int) (Required) Term taxonomy ID. So your function is missing the $tt_id parameter.
get_terms does exactly what it says, it retrieves all terms of the specified taxonomy Retrieve the terms in a taxonomy or list of taxonomies. There are a couple of functions that you can make use of here. You nedd to follow the links, each functions is well documented with examples. You just need to choose … Read more
To get children with get_terms() you have two options. You can either use the argument parent, which will only get direct children, so only one level down; or you use child_of, which gets all descendants, meaning until last level down. Both parent and child_of need an integer as value, which would in both cases be … Read more
WordPress tracks which object types taxonomy applies to. This can be established on taxonomy registration or at some point after, so you shouldn’t be trying to do this too early. The approach would be to retrieve the list of taxonomies for the native post type and use it with lower level function, which supports multiple … Read more
Sounds like the author should be a taxonomy to me. You can have multiple authors to one book and multiple books to one or multiple authors, just like you can do with tags.
You can use: $post_id = wp_insert_post($args); to get the ID of the inserted post. You can try this: $terms = wp_get_object_terms($post_id, ‘thread_tag’); to get the terms from your post with $post_id. You can check out the Codex: http://codex.wordpress.org/Function_Reference/wp_get_object_terms You can then use get_children() $args = array( ‘post_mime_type’ => ‘image’, ‘post_parent’ => $post_id, ‘post_type’ => ‘attachment’ … Read more
As I said, this is doable, but we need to do careful planning as this is quite a heavy operation. On my test installation with a post count of just 13 posts, and 3 terms per taxonomy, the db is visited 20 times and the complete operation takes 0.03613 seconds. I have tried a couple … Read more
I’m not completely sure that you do actually need get_terms() twice. It looks very ineffecient and overboard. I don’t know if you need this for ordering purposes, but still, there are better ways of doing this without hitting the db so hard. One alternative is to make one call to get_terms() and then use usort() … Read more
