    The page_attributes_meta_box() function in WordPress is a utility function primarily used in the WordPress backend, specifically in the page editing screen. It's designed to display the form fields related to the attributes of a page. The key details of this function are as follows:

    Function:

    • Name: page_attributes_meta_box
    • Purpose: Displays page attributes form fields in the WordPress editor.

    Parameters:

    • $post (WP_Post) [required]:
      • Description: This parameter is the current post object that is being edited.
      • Type: WP_Post
      • Role: It provides the function with the necessary data about the post/page that is currently being edited, so that the appropriate attributes (like parent page, template, and order) can be displayed and modified.

    Functionality:

    When you invoke this function, it renders the fields in the page editor that allow you to modify page attributes. These attributes typically include:

    1. Parent: This dropdown lets you select a parent page, establishing a hierarchy of pages (useful for nested pages or creating a dropdown menu structure).

    2. Template: Allows you to select a template for your page. Templates are defined by your theme and can drastically alter the layout and functionality of the page.

    3. Order: This numeric field lets you dictate the order in which the page appears in menus and lists. Lower numbers are displayed first.

    Sample Usage:

    In most cases, you won't need to call this function directly, as it's handled internally by WordPress. However, if you're creating a custom page editing screen or modifying the default WordPress behavior, you might use it like this:

    add_action('add_meta_boxes', 'custom_add_meta_boxes');
    
    function custom_add_meta_boxes() {
        add_meta_box('pageparentdiv', __('Page Attributes'), 'page_attributes_meta_box', 'page', 'side', 'high');
    }
    

    In this example, custom_add_meta_boxes is a function hooked to the add_meta_boxes action. It calls add_meta_box, specifying 'page_attributes_meta_box' as the callback function. This setup adds the standard Page Attributes meta box to the side of the page editing screen with high priority.

    Notes:

    • It's part of the WordPress Core and adheres to the design and functionality patterns of WordPress.
    • It should be used in the context of admin pages, specifically in the editing screens for posts and pages.
    • Customizing the output or behavior of this function typically involves using hooks and filters provided by WordPress rather than modifying the function directly.

    This function is a good example of how WordPress allows theme and plugin developers to interact with and modify the default behavior of post editing screens.
