It's always good for the reader to know the author of the article that they're currently reading. It's even better if they can learn some extra information about the author, such as his website, a short bio, and so on. While many modern themes offer the option to display author info on posts, if your theme does not, you may want to consider adding this information to your posts, as it benefits both your site visitors and your authors.
In this recipe, you'll learn how to edit your single.php
theme file to automatically retrieve the author-related information, and display it at the top of the page.
Note
Note that many themes today offer the option to display author info, photos, or avatars. This recipe, therefore, is intended for themes that lack this capacity.
All you need to execute this recipe is your favorite text editor and access to the theme files of your WordPress installation.
