这是解决方案

<?php
        if ( $gallery_sliders ) {
          foreach ( $gallery_sliders as $attachment_id => $img_full_url ) {
            echo "<li>";
            echo '<div class="item">'. $full = wp_get_attachment_link($attachment_id, 'ashmawi_post_standard'); echo esc_url($full[0]) .'</div>';
            echo "</li>";
            }
        }
  ?>
