Using the_author to display the author of a WordPress post

The the_author function in WordPress is used to display the name of the author of a post. When this function is called within the WordPress Loop, it retrieves the author’s name associated with the current post being processed. This can be useful for themes and templates that need to show the name of the person who wrote the content.

By using the_author, developers can dynamically display the author’s name without manually inputting it for each post. This function fetches the author’s name directly from the WordPress database, ensuring that the correct author’s name is displayed for each post.

Some common scenarios where the_author might be used include:

  • Displaying the author’s name in the post’s metadata section.
  • Showing the author’s name in the byline of a blog post.
  • Including the author’s name in post excerpts or summaries.

Parameters

  • $deprecated (string), optional. Default is ”. This parameter is deprecated.
  • $deprecated_echo (bool), optional. Default is true. This parameter is deprecated. Use get_the_author() instead. It determines whether to echo the string or return it.

Return Value

The function returns the author’s display name as a string, or null if the author’s name is not available, sourced from get_the_author().

Examples

How to Display the Author’s Name in a Post

<?php
if ( have_posts() ) {
 while ( have_posts() ) {
 the_post();
 the_author();
 }
}
?>

This snippet checks if there are posts using have_posts() and then iterates through each post using while ( have_posts() ). Inside the loop, it calls the_post() to set up post data and then displays the author’s name using the_author().

How to Display the Author’s Name with Custom HTML

<?php
if ( have_posts() ) {
 while ( have_posts() ) {
 the_post();
 echo '<p>Written by: ';
 the_author();
 echo '</p>';
 }
}
?>

This snippet also checks for posts and iterates through them. However, it wraps the author’s name in a custom HTML paragraph. The the_author() function is used to display the author’s name within the <p> tags.

How to Display the Author’s Name Only if Logged In

<?php
if ( is_user_logged_in() ) {
 if ( have_posts() ) {
 while ( have_posts() ) {
 the_post();
 the_author();
 }
 }
}
?>

This snippet first checks if a user is logged in using is_user_logged_in(). If the user is logged in, it then checks for posts and iterates through them, displaying the author’s name with the_author().

Conclusion

The the_author function in WordPress serves as a straightforward method for displaying the author of a post. This function retrieves and echoes the name of the post’s author, providing a seamless way to include author attribution in themes and templates. It can be particularly useful in blog posts, news articles, and any other content types where author information is relevant. By leveraging the_author, developers can ensure that author details are consistently and accurately presented, enhancing the overall content structure and user experience on WordPress sites.
