📝 Title: How to Get Author Info from Post ID in WordPress 🖊️

Introduction:

Do you want to display the author information, including the author's page link and avatar, in the sidebar of a single post page outside the post loop? If yes, you're in the right place. In this blog post, we'll uncover the best way to obtain the author info from a post ID in WordPress.

👉 Problem: Retrieving the Author Info from Post ID

Let's break down the problem described by the user. They have a custom function that successfully returns the post ID using the WordPress global variable $wp_query. However, they are unsure about the next step in obtaining the author meta, including the author page link and avatar.

🔍 Solution: Fetching the Author Info Using WordPress Functions

To retrieve the author information from a post ID, you can utilize the following steps:

1. Step One: Acquire the Post ID.

   You can use the provided function `this_post_id()` to get the post ID. It accesses the global `$wp_query` variable and retrieves the ID of the current post.🔢

2. Step Two: Fetch the Author's ID.

   With the post ID available, you can now use WordPress's built-in function `get_post_field()` to retrieve the author ID. You specify the post ID, the field you want (which is `'post_author'` in this case), and the filter you want the value to go through (optional). Once you have the author ID, you can proceed to the next step.🙌$author_id = get_post_field( 'post_author', $post_id );

3. Step Three: Retrieve the Author's Data.

   Now that you have the author ID, you can fetch the complete author data using the `get_userdata()` function. This function returns an object containing multiple properties such as the author's display name, website, email, and avatar. To get the author's page link, you can use `$author_data->user_url`, and for the avatar, you can use `$author_data->avatar` (or any other desired information).👤$author_data = get_userdata( $author_id );

4. Step Four: Display the Author Info.

   Finally, you can output the author info in your sidebar or anywhere you desire using HTML markup and the fetched author data. You can customize the output according to your needs, incorporating the author's page link, avatar, or any other author information.🎉

Now that you know the steps to fetch the author info from a post ID, you can enhance your WordPress website by displaying the author details prominently across your single post pages.
