如何显示类别列表的最新帖子的上次更新日期

我在我的网站上创建了一个页面，只需使用以下命令列出一个类别中的所有子类别：

<?php
$args       = array(
                \'show_option_all\' => \'\',
                \'child_of\' => 8,
                \'order\' => \'DESC\',
                \'orderby\' => \'ID\'
);
$categories = get_categories($args);
foreach ($categories as $category) {
                echo \'<a href="\' . get_category_link($category->term_id) . \'" title="\' . sprintf(__("View all posts in %s"), $category->name) . \'" \' . \'>\' . $category->name . \'</a> <br>\';
}
?>

我试图在括号中的名字后面加上最近一篇文章的日期，但似乎想不出一个方法。

编辑：使其正常工作

<?php
// select all sub categories of parent cat with id \'8\'
$categories = get_categories([\'parent\' => 8,\'orderby\' => \'ID\',\'order\' => \'DESC\',]);
// For each sub category find last post
foreach ( $categories as $category ) {
    $args = array(
    \'cat\'            => $category->term_id,
    \'post_type\'      => \'post\',
    \'posts_per_page\' => \'1\',
    \'orderby\'        => \'date\',
    \'order\'          => \'DESC\'
    );
    $query = new WP_Query( $args );
    if ( $query->have_posts() ) { 
       while ( $query->have_posts() ) {
            $query->the_post();
            echo \'<a href="\' . get_category_link($category->term_id) . \'" title="\' . sprintf(__("View all posts in %s"), $category->name) . \'" \' . \'>\' . $category->name . \' (\'. get_the_date( "F j, Y", get_the_id() ) .\')</a> <br>\'; 
       }
    } else {
         echo \'<a href="\' . get_category_link($category->term_id) . \'" title="\' . sprintf(__("View all posts in %s"), $category->name) . \'" \' . \'>\' . $category->name . \'</a> <br>\'; 
    }
    wp_reset_postdata(); 
    }
?>

<?php // select all sub categories of parent cat with id \'8\' $categories = get_terms( \'category\', array( \'orderby\' => \'ID\', \'parent\' => 8 ) ); // For each sub category find last post foreach ( $categories as $category ) { $args = array( \'cat\' => $category->term_id, \'post_type\' => \'post\', \'posts_per_page\' => \'1\', \'orderby\' => \'date\', \'order\' => \'DESC\' ); $query = new WP_Query( $args ); if ( $query->have_posts() ) { while ( $query->have_posts() ) { $query->the_post(); echo \'<a href="\' . get_category_link($category->term_id) . \'" title="\' . sprintf(__("View all posts in %s"), $category->name) . \'" \' . \'>\' . $category->name . \' (\'. get_the_date( ** FORMAT HERE **, get_the_id() ) .\')</a> <br>\'; } } else { echo \'<a href="\' . get_category_link($category->term_id) . \'" title="\' . sprintf(__("View all posts in %s"), $category->name) . \'" \' . \'>\' . $category->name . \'</a> <br>\'; } wp_reset_postdata(); } ?>
