Video Tutorial The custom post type

As with taxonomies, it is possible to record new types of content which can then be administered and consulted.

function montheme_types () {
    register_post_type ('good', (
        'label' => 'Good',
        'public' => true,
        'menu_position' => 3,
        'menu_icon' => 'dashicons-building',
        'supports' => ('title', 'editor', 'thumbnail'),
        'show_in_rest' => true,
        'has_archive' => true,
add_action ('init', 'montheme_types');

Once this type of content has been declared, you can manage it from the backoffice. However, if you try to view your content, you may get a 404 error. You will need to update your site's permalinks so that the URLs corresponding to your new content are managed.
