WordPress使用標簽無法加載相關帖子

Question

我正在使用WordPress PHP代碼獲取當前帖子的相關帖子，但是當我使用此代碼時，它僅顯示當前帖子

我的代碼如下

$posttags = wp_get_post_tags(get_the_id(), array( 'fields' => 'slugs' ));

        $args = array( 
                'posts_per_page' => 3,
                'tax_query'      => array(
                    array(
                        'taxonomy'  => 'post_tag',
                        'field'     => 'slug',
                        'terms'     => $posttags
                    )
                )
            );

        $postslist = get_posts( $args );

誰能幫我使用當前的帖子標簽獲取其他相關帖子。 謝謝

請參考此鏈接以獲取更多詳細信息： https : //developer.wordpress.org/reference/classes/wp_query/

<?php
// For use in the loop, list 3 post titles related to first tag on current post
$tags = wp_get_post_tags($post->ID);

if ($tags) {
    echo 'Related Posts';

    $first_tag = $tags[0]->term_id;

    $args = array(
        'tag__in' => array($first_tag),
        'post__not_in' => array($post->ID),
        'posts_per_page' => 3,
        'caller_get_posts' => 1
    );
    $my_query = new WP_Query($args);

    if ( $my_query->have_posts() ) {
        while ($my_query->have_posts()) : $my_query->the_post();
        ?>
            <a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a>
        <?php
        endwhile;
    }
    wp_reset_query();
}
?>
