我使用以下内容将类别分配给我的WordPress媒体库（在functions.php):

function wptp_add_categories_to_attachments() {
    register_taxonomy_for_object_type( \'category\', \'attachment\' );
}
add_action( \'init\' , \'wptp_add_categories_to_attachments\' );

每个媒体库项目都分配了特定的类别。。。我有一些从媒体库返回最新5幅图像的代码，如下所示（在footer.php):

<?php
    $args = array(
        \'post_type\' => \'attachment\',
        \'post_mime_type\' => \'image\',
        \'orderby\' => \'post_date\',
        \'order\' => \'desc\',
        \'posts_per_page\' => \'5\',
        \'post_status\' => \'inherit\'
    );
    query_posts($args);
?>
    <?php if ( have_posts() ) : ?>
        <div class="wrap">
            <h5><span>Recently</span> Added</h5>
            <ul>
                <?php
                    while ( have_posts() ) : the_post();
                    $url = get_attachment_link(get_post_thumbnail_id());
                    $image = wp_get_attachment_image_src(get_the_ID(), "thumbnail");
                ?>
                    <li><a href="<?php echo $url; ?>"><img src="<?php echo $image[0]; ?>"></a></li>
                <?php endwhile; ?>
            </ul>
        </div>
    <?php else : ?>
        <div class="wrap">
            <h5>Oops...</h5>
            <p><?php _e( \'Sorry, no posts matched your criteria.\' ); ?></p>
        </div>
    <?php endif; ?>
<?php wp_reset_query(); ?>

我想做的是，如果图像具有指定的类别，则只返回这些图像。

非常感谢您的帮助。

谢谢，乔希
