Register a new block category for “My Plugin” if it doesn’t exist already.
Note: You can also pass a second argument
$postto generate a different category depending on the post’s content or type./** * Creating a new (custm) block category. * * @param array $categories List of block categories. * @return array */ function wpdocs_new_block_category( $categories ) { // Plugin’s block category title and slug. $block_category = array( 'title' => esc_html__( 'My Plugin', 'text-domain' ), 'slug' => 'myplugin' ); $category_slugs = wp_list_pluck( $categories, 'slug' ); if ( ! in_array( $block_category['slug'], $category_slugs, true ) ) { $categories = array_merge( $categories, array( array( 'title' => $block_category['title'], // Required 'slug' => $block_category['slug'], // Required 'icon' => 'wordpress', // Slug of a WordPress Dashicon or custom SVG ), ) ); } return $categories; } add_filter( 'block_categories', 'wpdocs_new_block_category' );Expand full source codeCollapse full source code
If you’ve come here because you’re getting deprecation notices about `block_categories`, as of 5.8 this filter is deprecated. Use `block_categories_all` instead.
If you need to apply categories based on post type or other $post data, you can do so like this:
/** * Create a custom block category for posts only. * * @param array $categories List of block categories. * @return array */ function wpdocs_post_block_category( $categories, $editor_context ) { if ( $editor_context->post instanceof WP_Post && 'post' === $editor_context->post->post_type ) { $categories = array_merge( $categories, array( 'title' => __( 'Title' ), // Required 'slug' => 'slug', // Required 'icon' => 'wordpress', // Slug of a WordPress Dashicon or custom SVG ) ); } return $categories; } add_filter( 'block_categories_all', 'wpdocs_post_block_category' );Expand full source codeCollapse full source code
