The WP_Query object contains a max_num_pages field which contains how many pages of posts there are. You can compare the current page number with it. (This is how get_next_posts_link() does it.) global $wp_query; $current_page = $wp_query->get( ‘paged’ ); if ( ! $current_page ) { $current_page = 1; } if ( $current_page == $wp_query->max_num_pages ) { … Read more
Here’s a very basic example.. /* Code assumes it will be in the theme functions.php file Update the enqueue path if using it elsewhere */ add_action( ‘add_meta_boxes_post’, ‘add_post_metabox’ ); function add_post_metabox() { wp_enqueue_script( ‘mytabs’, get_bloginfo( ‘stylesheet_directory’ ). ‘/mytabs.js’, array( ‘jquery-ui-tabs’ ) ); add_meta_box( ‘examplebox’ , __(‘Example box’), ‘my_example_metabox’, ‘post’, ‘side’, ‘core’/*,array()*/); } function my_example_metabox() { … Read more
Aside from the technical aspects, Categories are for broad topics while Tags are for adding more detail to your posts’ subject. Lorelle has written the definitive guide on the difference between categories and tags. You might also want to check out the WordPress.com guide on Categories vs. Tags.
Figured it out! The code below automatically lists all categories and each categories posts! $args = array( ‘number’ => $number, ‘orderby’ => ‘title’, ‘order’ => ‘ASC’, ‘hide_empty’ => $hide_empty, ‘include’ => $ids ); $product_categories = get_terms( ‘product_cat’, $args ); $count = count($product_categories); if ( $count > 0 ){ foreach ( $product_categories as $product_category ) { … Read more
You will need to use the ID value returned by $category[0]->category_parent and pass it through get_term(). Example: $category = get_the_category(); $category_parent_id = $category[0]->category_parent; if ( $category_parent_id != 0 ) { $category_parent = get_term( $category_parent_id, ‘category’ ); $css_slug = $category_parent->slug; } else { $css_slug = $category[0]->slug; }
Multiple categories can be separated by comma like below http://example.com/wp-json/wp/v2/posts?categories=20,30 hope this helps

You can’t just pass the string “parent” to get_categories. You have to pass the ID of the parent. $categories=get_categories( array( ‘parent’ => $cat->cat_ID ) ); Notice that there are two similar but not equal “get child” parameters that you can use. child_of (integer) Display all categories that are descendants (i.e. children & grandchildren) of the … Read more
