下面是我的代码，我想将其更改为在术语为空时隐藏分类法：
<ul class="info-list">
<li>
<label><?php echo esc_html__( \'Actor:\', \'amy-movie\' ); ?></label>
<span><?php echo amy_movie_get_movie_taxomony( $post->ID, \'amy_actor\' ); ?></span>
</li>
<li>
<label><?php echo esc_html__( \'Director:\', \'amy-movie\' ); ?></label>
<span><?php echo amy_movie_get_movie_taxomony( $post->ID, \'amy_director\' ); ?></span>
</li>
<label><?php echo esc_html__( \'Genre:\', \'amy-movie\' ); ?></label>
<span><?php echo amy_movie_get_movie_taxomony( $post->ID, \'amy_genre\' ); ?></span>
</li>
<li>
<label><?php echo esc_html__( \'Release:\', \'amy-movie\' ); ?></label>
<span><?php echo esc_attr( date( get_option( \'date_format\' ), strtotime( $mdetails[\'movie_release\'] ) ) ); ?></span>
</li>
<li>
<label><?php echo esc_html__( \'Language:\', \'amy-movie\' ); ?></label>
<span><?php echo esc_attr( $mdetails[\'movie_language\'] ); ?></span>
</li>
<?php if ( amy_get_option( \'enable_m_cinema\', true ) == true ) : ?>
<li>
<label><?php echo esc_html__( \'Cinema:\', \'amy-movie\' ); ?></label>
<?php
if ( ! empty( $cinemas ) ) {
$numItems = count( $cinemas );
$i = 0;
foreach ( $cinemas as $cinema ) {
if ( ++$i === $numItems ) {
$space = \'\';
} else {
$space = \', \';
}
?>
<a href="<?php echo get_permalink( $cinema ); ?>"><?php echo get_the_title( $cinema ); ?></a>
<?php echo esc_attr( $space ); ?>
<?php
}
}
?>
</li>
<?php endif; ?>
</ul>

许多自动主题正是针对标准标记和类别这样做的，也强调了初学者主题。直接从GitHub上的源代码开始：
$categories_list = get_the_category_list( esc_html__( \', \', \'_s\' ) );
if ( $categories_list ) {
/* translators: 1: list of categories. */
printf( \'\' . esc_html__( \'Posted in %1$s\', \'_s\' ) . \'\', $categories_list ); // WPCS: XSS OK.
}根据分类法的需要进行调整。
