When you create a term for a hierarchical taxonomy, if you don’t specify a parent, its parent ID is set to 0. In other words, it becomes a parent term. Edited with regards to comments: Add specifically each term you wish to add to the post (parent terms aren’t automatically added if their children are). … Read more
The meta_key field for the wp_postmeta table is set as varchar type entries with a length of 255 characters. Seems pretty lengthy. It’s meta_value partner parameter is set as longtext type.

You can use wp_dropdown_categories(): Display or retrieve the HTML dropdown list of categories. $args = array( ‘show_count’ => 1, ‘hierarchical’ => 1, ‘taxonomy’ => ‘my_taxonomy’, ); wp_dropdown_categories( $args );
The problem you are facing is that get_the_terms() returns an array (or false or a WP_Error-Object), not a string. So, assuming that you have multiple terms for images, you could use a code like this: if( $labels && !is_wp_error( $labels ) ) { foreach( $labels as $label ) { $labelarray[] = $label->name; } $labelstring = … Read more
Instead of get_the_terms try using get_terms and set the hierarchal argument to true. Also make sure you show empty so you are not hiding your empty categories. Try something like this: $args = array( ‘hide_empty’ => false, ‘hierarchical’ => true ); $terms = get_terms(‘portfolio_pt’, $args); foreach($terms as $term) echo $term->name;
You can use the count property of the taxonomy term and if it is > 1, then show the term linked to archive. // inside loop, get the terms of a custom taxonomy for the current post $terms = get_the_terms( get_the_ID(), ‘your_custom_taxonomy’ ); // cycle the terms and display the name, linked to archive if … Read more
You can use get_term_by() for this <?php $term_id = array_pop(get_sub_field(‘sector_selector’)); $catinfo = get_term_by( ‘id’, $term_id, ‘name_of_the_taxonomy’ ); print $catinfo->slug;

Editing the taxonomy archive page, the user would see checkboxes (or radio buttons, or a select menu) for the taxonomy terms. In the corresponding “taxonomy archive” template (from link above)… <?php $terms … Read more
My bad – the mark up for the edit page is different than add. Used this instead add_action(‘provider_edit_form_fields’, array($this, ‘category_metabox_edit’), 10, 1); // add image field in edit form function category_metabox_edit($tag) { $term_val = get_term_meta($tag->term_id, ‘show_on_provider’, true); $term_val == 1 ? $checked = ‘checked’ : $checked = ”; echo ‘<tr class=”form-field”> <th scope=”row” valign=”top”><label for=”show_on_provider”>’ … Read more
Keep in mind that the return value of get_the_terms() can be of the type of array|WP_Error Your snippet should check if you get the correct type returned $terms = get_the_terms( 0, ‘product_tag’ ); if ( ! is_wp_error( $terms ) AND is_array( $terms ) AND ! empty( $terms ) ) { foreach( $terms as $term ) … Read more
