我想获取161到166个图像,而无需调用整个媒体库阵列并拼接它们。随着时间的推移,我在那里的信息越多,我的网站速度就会越慢。这是我到目前为止所拥有的,我使用array\\u reverse来反转ID,以便最近的上载是最后一次,我使用array\\u splice来查找需要提取的图像。有没有更直接的方法让我找到ID为161到166的图像?
function get_images_from_media_library() {
                $args = array(
                    \'post_type\' => \'attachment\',
                    \'post_mime_type\' =>\'image\',
                    \'post_status\' => \'inherit\',
                    \'posts_per_page\' => -1,
                );
                $query_images = new WP_Query( $args );
                $images = array();
                foreach ( $query_images->posts as $image) {
                    $images[]= $image->guid;
                }
                $images = array_reverse($images);
                $images = array_splice($images, 3,6);
                return $images;
            }
            $img = get_images_from_media_library();
            foreach($img as $image){
                echo "<img src=\'$image\'/>";
            }

                    添加post__in (两条下划线)到您的$args:
$args = array(
    \'post_type\' => \'attachment\',
    \'post_mime_type\' =>\'image\',
    \'post_status\' => \'inherit\',
    \'posts_per_page\' => -1,
    \'post__in\' => array( 161, 162, 163, 164, 165, 166 ),
);
