在WordPress中的作者存档页面上获取作者姓名

Question

I am making template for archives in WordPress website, but my template will not work for author name on author archive.

I have this:

<?php if (is_category('')) { ?>
<?php single_cat_title(); ?>

<?php } elseif (is_author('')) { ?>
<?php get_userdata( get_query_var('author') );?>

<?php } elseif (is_day('')) { ?>
<?php echo get_the_time('F j, Y'); ?>

<?php } elseif (is_month('')) { ?>
<?php echo get_the_time('F Y'); ?>

<?php } elseif (is_year('')) { ?>
<?php echo get_the_time('Y'); ?>

<?php } elseif (is_tag('')) { ?>
<?php echo single_tag_title(''); ?>
<?php } ?>

This part will not work:

<?php } elseif (is_author('')) { ?>
<?php get_userdata( get_query_var('author') );?>

Answer 1

The function you're using in is_author returns a user object. It doesn't output anything.

Correct usage would be:

<?php 
// Get current author.
$curauth = ( get_query_var( 'author_name' ) ) ? get_user_by( 'slug', get_query_var( 'author_name' ) ) : get_userdata( get_query_var( 'author' ) ); ?>

Author: <?php echo $curauth->nickname; ?>

Also the empty string isn't necessary with is_category etc.
