advert category type

Hi,
there is no such option right now i am afraid, i will see if i can create a code snippet which will allow doing it.

That would be great if you can Greg.

You should be able to show Category column in the wp-admin / Classifieds and filter by the category after adding the code below in your theme functions.php file

function add_new_advert_column__advert_category($header_text_columns) {
  $header_text_columns['advert_category'] = "Category";
  return $header_text_columns;
}
add_filter('manage_edit-advert_columns', 'add_new_advert_column__advert_category', 1000);
add_action('manage_advert_posts_columns', 'add_new_advert_column__advert_category', 1000);
function show_order_column__advert_category($name){
  global $post;

  switch ($name) {
    case 'advert_category':
        $advert_category = get_the_terms( $post->ID, 'advert_category' );
        if( isset( $advert_category[0] ) ) {
            $c = $advert_category[0];
            echo esc_html( $c->name );
        } else {
            printf( '—' );
        }
      break;
   default:
      break;
   }
}
add_action('manage_advert_posts_custom_column','show_order_column__advert_category');
function order_column_register_sortable__advert_category($columns){
  $columns['advert_category'] = 'advert_category';
  return $columns;
}
add_filter('manage_edit-advert_sortable_columns','order_column_register_sortable__advert_category');

function filter_by__advert_category( $post_type, $which ) {

	// Apply this only on a specific post type
	if ( 'advert' !== $post_type )
		return;

	// A list of taxonomy slugs to filter by
	$taxonomies = array( 'advert_category' );

	foreach ( $taxonomies as $taxonomy_slug ) {

		// Retrieve taxonomy data
		$taxonomy_obj = get_taxonomy( $taxonomy_slug );
		$taxonomy_name = $taxonomy_obj->labels->name;

		// Retrieve taxonomy terms
		$terms = get_terms( array(
            'taxonomy' => $taxonomy_slug,
            'hide_empty' => false,
        ) );

		// Display filter HTML
		echo "<select name='{$taxonomy_slug}' id='{$taxonomy_slug}' class='postform'>";
		echo '<option value="">' . sprintf( esc_html__( 'Show All %s', 'text_domain' ), $taxonomy_name ) . '</option>';
		foreach ( $terms as $term ) {
			printf(
				'<option value="%1$s" %2$s>%3$s</option>',
				$term->slug,
				( ( isset( $_GET[$taxonomy_slug] ) && ( $_GET[$taxonomy_slug] == $term->slug ) ) ? ' selected="selected"' : '' ),
				$term->name
			);
		}
		echo '</select>';
	}

}
add_action( 'restrict_manage_posts', 'filter_by__advert_category' , 10, 2);
