I’m not sure, if you already found a solution for this, but when I searched for a similar one yesterday, I found this tutorial on WPtuts very helpful. It uses radio buttons, but you can easily modify it to get it working with checkboxes as well. http://wp.tutsplus.com/tutorials/creative-coding/how-to-use-radio-buttons-with-taxonomies/
Solved! add_action( ‘create_category’, ‘save_extra_taxonomy_fields’, 10, 2 ); Props to the Category Meta plugin. I downloaded various category meta plugins from the WP repo, and this one has the ability to add the meta data on the Add New screen. I dug through the code and found the elusive create_{term} hook.
tax_query takes an array of tax query arguments arrays (it takes an array of arrays) but you are using only single array. The correct code is as following. $uposts = get_posts( array( ‘post_type’ => ‘product’, ‘numberposts’ => -1, ‘tax_query’ => array( array( ‘taxonomy’ => $cat->taxonomy, ‘field’ => ‘slug’, ‘terms’ => array($cat->slug), ‘operator’ => ‘IN’, ) … Read more
Tag and Category archive queries default to querying only the post post type, to add your custom post type to those queries, you can use the pre_get_posts action: function wpa_cpt_tags( $query ) { if ( $query->is_tag() && $query->is_main_query() ) { $query->set( ‘post_type’, array( ‘post’, ‘object’ ) ); } } add_action( ‘pre_get_posts’, ‘wpa_cpt_tags’ );
Attributes are stored on wp_term_relationships. Ex: +————–+——————-+——————-+ | object_id | term_taxonomy_id | term_taxonomy_id | +————–+——————-+——————-+ | 91 | 48 | 0 | +————–+——————-+——————-+ Product 91 has an attribute 48
I’ve logged a ticket against this with trac: http://core.trac.wordpress.org/ticket/20536 However, it turns out that for the time being it IS necessary, as WordPress currently (since 2.x) has a bug that DOES associate two terms with the same name to the same term_id! So it IS possible (though incorrect) for a single term to be associated … Read more
Hmmm, can’t remember or find fitting function either. There is wp_set_object_terms() that is used in multiple wrappers like wp_set_post_categories(). It can overwrite categories for a post. So you can get post categories, check for unwanted one and write it back excluding unwanted in that case.
Normally to add fields to the quick edit field, we should use ‘quick_edit_custom_box’ action hook that is triggered only for custom columns, because core columns are explicitly excluded (see code). If we add a custom column, then it will be shown in the list table, but it doesn’t make sense, because the column description is … Read more
You can have the term input empty, e.g. if( has_term( ”, ‘genre’ ) ) { // do something } to see if the current post object has any terms in the genre taxonomy. It uses is_object_in_term() where: The given terms are checked against the object’s terms’ term_ids, names and slugs. Terms given as integers will … Read more
I came up with a solution for your first question. i.e the tax metabox that only suggests terms from existing terms list but does not allow you to add new terms. The solution is jQuery based and modifies the default behavior of the tags (i.e non heirarchical taxonomies) meta box. Limitation: Currently it only allows … Read more
