Argument missing from 'register_post_type' codex docs

There is a label missing from the elaborate example of registering a new post type.

'view_items' is not present, and is used when archive is enabled, and the link in the admin menu bar is shown. By default, this shows 'View Posts' to open the archive page from wp-admin.

This label will rename this to suit your post type, and should be included between 'view_item' and 'all_items'.


add_action( 'init', 'codex_book_init' );
 * Register a book post type.

function codex_book_init() {
        $labels = array(
                'name'               => _x( 'Books', 'post type general name', 'your-plugin-textdomain' ),

That "elaborate" example is missing much more labels than just view_items :-) I'd say it's easier to just point to the docs instead of listing all possible labels there.

The good thing is: the codex is a wiki, which anyone can edit! So if you see an issue like this that you think is worth fixing, you can just log in with your WordPress.org username and edit the page.

That being said, the source of truth for documentation is https://developer.wordpress.org/reference as we're slowly moving away from Codex.

The relevant documentation for register_post_type() explicitly says this about the labels:

An array of labels for this post type. If not set, post labels are inherited for non-hierarchical types and page labels for hierarchical ones. See get_post_type_labels() for a full list of supported labels.

See https://developer.wordpress.org/reference/functions/get_post_type_labels/ for the full list of labels.
