推荐答案

HTML：

<a href="<?php echo get_post_meta($post->ID,'mixtape_link',true); ?>" id="thisdownloads" class="button small"><span>Download Now!</span></a>

<script>
    jQuery(document)ready(function() {

      jQuery(this).on('change', '#thisdownloads', function() {

        jQuery.ajax({
        type: "POST",
        url: "/wp-admin/admin-ajax.php",

        data: {
            action: 'update_downloads',
            ID: '<?php get_the_ID(); ?>'// if within the loop you need a correct id for this to work...........
        },
        success: function (output) {}
           console.log(output);
        });


      });
    });

</script>

PHP的：

php:

    add_action('wp_ajax_update_downloads', 'update_downloads');
add_action('wp_ajax_nopriv_update_downloads', 'update_downloads');

function update_downloads() {

  $id= sanitize_text_fields($_POST['ID']);

  $downloads= get_post_meta($id,'_downloads',true);

  if(!$downloads):
     $downloads=1;
  else:
     $downloads++;
  endif;

  update_post_meta($id,'_downloads', $downloads);
  echo $downloads;
  exit();

}

应该是足够接近，如果你不能做这项工作，你需要研究以下内容：
