下面是我如何实现一个简单的媒体工作流的。安全检查和消毒取决于每个人。

基于Wordpress版本：4.9.8

创建附件帖子|处理介质

if (!empty($_FILES) && isset($_POST[\'postid\'])) {
  media_handle_upload("attachments", $_POST[\'postid\']);
}

使用时，附件不可能处于挂起状态media_handle_upload. 在这种情况下，需要使用过滤器。使用前应添加此筛选器media_handle_upload.

add_filter(\'wp_insert_attachment_data\', \'SetAttachmentStatusPending\', \'99\');

function SetAttachmentStatusPending($data) {
  if ($data[\'post_type\'] == \'attachment\') {
    $data[\'post_status\'] = \'pending\';
  }

  return $data;
}

现在，附件帖子添加了挂起的post\\u状态。

在媒体库中显示挂起的帖子

Worpress媒体库仅显示具有private或inherit post\\u状态的帖子。要显示具有挂起状态的帖子，我们可以挂接

add_action(\'pre_get_posts\', array($this, \'QueryAddPendingMedia\'));

function QueryAddPendingMedia($query)
{
  // Change query only for admin media page
  if (!is_admin() || get_current_screen()->base !== \'upload\') {
    return;
  }

  $arr = explode(\',\', $query->query["post_status"]);
  $arr[] = \'pending\';
  $query->set(\'post_status\', implode(\',\', $arr));
}

操作和批量操作要完成工作流，我们需要发布挂起的媒体。为此，我们可以向媒体库添加（批量）操作。

添加批量操作

add_filter(\'bulk_actions-upload\', \'BulkActionPublish\');

function BulkActionPublish($bulk_actions)
{
  $bulk_actions[\'publish\'] = __(\'Publish\');

  return $bulk_actions;
}

添加行操作要添加到行操作的链接，此代码很有用

add_filter(\'media_row_actions\', \'AddMediaPublishLink\', 10, 3);

function AddMediaPublishLink(array $actions, WP_Post $post, bool $detached)
{
  if ($post->post_status === \'pending\') {
    $link = wp_nonce_url(add_query_arg(array(\'act\' => \'publish\', \'itm\' => $post->ID), \'upload.php\'), \'publish_media_nonce\');
    $actions[\'publish\'] = sprintf(\'<a href="%s">%s</a>\', $link, __("Publish"));
  }

  return $actions;
}

处理操作

add_action(\'load-upload.php\', \'RowActionPublishHandle\');
add_filter(\'handle_bulk_actions-upload\', \'BulkActionPublishHandler\', 10, 3);

function BulkActionPublishHandler($redirect_to, $doaction, $post_ids)
{
  if ($doaction !== \'publish\') {
    return $redirect_to;
  }

  foreach ($post_ids as $post_id) {
    wp_update_post(array(
      \'ID\' => $post_id,
      \'post_status\' => \'publish\'
    ));
  }

  return $redirect_to;
}

function RowActionPublishHandle()
{
  // Handle publishing only for admin media page
  if (!is_admin() || get_current_screen()->base !== \'upload\') {
    return;
  }

  if (isset($_GET[\'_wpnonce\']) && wp_verify_nonce($_GET[\'_wpnonce\'], \'publish_media_nonce\')) {
    if (isset($_GET[\'act\']) && $_GET[\'act\'] === \'publish\') {
      wp_update_post(array(
        \'ID\' => $_GET[\'itm\'],
        \'post_status\' => \'publish\'
      ));
    }
  }
}
