    1. $field (string, optional): The user field to retrieve. The default value is an empty string.
    2. $user_id (int | false, optional): The User ID. If not provided, it defaults to the author of the current post. The default value is false.


    • Type: string
    • Description: The function returns the value of the author’s field from the current author’s database object. If the requested field is not found or if the author does not exist, it returns an empty string.

    Sample Usage:

    To use get_the_author_meta(), you can include it in your WordPress theme or plugin code. Here's an example of how it can be used:

    // Retrieve and display the display name of the post's author
    $author_display_name = get_the_author_meta('display_name');
    echo 'Author: ' . esc_html($author_display_name);

    In this example, get_the_author_meta('display_name') retrieves the display name of the author of the current post. The esc_html() function is used for sanitization before outputting the name to the browser, which is a good security practice in WordPress development.

    Remember that the actual data retrieved will depend on the fields set for each user in the WordPress database.
