   Display a User Email Address
   Displays the email address for user ID 25.

   
   <p><?php printf( __( 'The email address for user id 25 is %s', 'textdomain' ), get_the_author_meta( 'user_email',25 ) ); ?></p>
   

Advanced Uses
A plugin may add an additional field in the registration or manage users, which adds a new value in the wp_usermeta (where wp_ is your data base prefix. For this example we will use a Twitter ID if a plugin set meta_key value to “twitter” and meta_value to “wordpress” then

<p><?php printf( __( 'This author’s Twitter name is %s', 'textdomain' ), get_the_author_meta( 'twitter' ) ); ?></p>

would return:

This author’s Twitter name is WordPress

And if you actually want to show the Author description using this function you can just do:

<?php $authorDesc = the_author_meta('description'); echo $authorDesc; ?>
