<?php
foreach((get_the_category()) as $category) {
if ($category->category_parent == \'7\') {
echo \'<a href="\' . get_category_link( $category->term_id ) . \'" title="\' . sprintf(__( "View all posts in %s" ), $category->name ) . \'" \' . \'>\' . $category->name.\'</a> \';
}
}
?>
您只需将7替换为您想要包含的任何类别
