WordPress: get author info / user details from post id

Some times we needed to pull out the author data from a post id. It is very easy do it in wordpress.

It can be accomplished by the_author_meta() function or get_the_author_meta() function. You will need call this function in your theme or plugin, through a hook.

the_author_meta() –> Outputs the data, just like echo
get_the_author_meta() -> holds the value in value.

We can get the data like this :

$auth = get_post($post_ID); // gets author from post
$authid = $auth->post_author; // gets author id for the post
$user_email = get_the_author_meta('user_email',$authid); // retrieve user email
$user_firstname = get_the_author_meta('user_firstname',$authid); // retrieve firstname
$user_nickname = get_the_author_meta('nickname,$authid); // retrieve user nickname

The following list of user fields you can retrieve using this function.

• user_login
• user_pass
• user_nicename
• user_email
• user_url
• user_registered
• user_activation_key
• user_status
