How to Get Post Author Name by Post ID:
Method 1: Using get_the_author_meta() Function:
One straightforward method to obtain the post author’s name is by utilizing the get_the_author_meta() function. This function retrieves the specified metadata of an author based on their user ID. To get the author’s name, we can pass the display_name parameter to this function.
$post_id = 123; // Replace with your desired post ID
$author_name = get_the_author_meta('display_name', get_post_field('post_author', $post_id));
echo "Author Name: " . $author_name;
Method 2: Using get_userdata() Function:
Another approach to retrieve the author’s name is by using the get_userdata() function. This function returns a WP_User object that contains all user data associated with a given user ID. We can then extract specific name fields from this object.
$post_id = 123; // Replace with your desired post ID
$user_info = get_userdata(get_post_field('post_author', $post_id));
$first_name = $user_info->first_name;
$last_name = $user_info->last_name;
$full_name = $user_info->first_name . ' ' . $user_info->last_name;
$nickname = $user_info->nickname;
$username = $user_info->user_login;
echo "First Name: " . $first_name;
echo "Last Name: " . $last_name;
echo "Full Name: " . $full_name;
echo "Nickname: " . $nickname;
echo "Username: " . $username;
Examples:
Let’s explore a few examples to better understand how these methods work.
Example 1: Retrieving the Author’s Name for a Single Post:
Suppose we have a post with the ID of 123, and we want to display the author’s full name in our template file. We can use Method 1 as follows:
$post_id = 123;
$author_name = get_the_author_meta('display_name', get_post_field('post_author', $post_id));
echo "Author Name: " . $author_name;
Example 2: Displaying Multiple Name Fields for an Author:
In some cases, you may need to display multiple name fields for an author, such as first name, last name, and username. Method 2 allows us to extract these details easily:
$post_id = 123;
$user_info = get_userdata(get_post_field('post_author', $post_id));
$first_name = $user_info->first_name;
$last_name = $user_info->last_name;
$username = $user_info->user_login;
echo "First Name: " . $first_name;
echo "Last Name: " . $last_name;
echo "Username: " . $username;
Conclusion:
Retrieving the author’s name by post ID in WordPress can be achieved using various methods. In this article, we covered two effective approaches using the get_the_author_meta() and get_userdata() functions. By following the provided examples and instructions, you can now easily display different name fields for a post author in your WordPress projects.
