基本範例
顯示目前使用者的電子郵件：[vg_display_data key="user_email" data_source="user_data"]
顯示目前使用者的名字：[vg_display_data key="first_name" data_source="user_meta"]
顯示目前使用者的全名：[vg_display_data key="first_name,last_name" data_source="user_meta"]
顯示目前文章的標題：[vg_display_data key="post_title" data_source="post_data"]
顯示目前文章的摘要：[vg_display_data key="post_excerpt" data_source="post_data"]
顯示文章 ID = 20 的分類：[vg_display_data object_id="20" key="category" data_source="post_terms" template="<b>Categories:</b> {{var}}" joiner=", "]
取得特色圖片網址：[vg_display_data key="_thumbnail_id" template="<b>Image url:</b> {{var}}" flag="file_url"]
取得特色圖片為 <img> 標籤：[vg_display_data key="_thumbnail_id" template="<b>Image:</b> {{var}}" flag="image_tag"]
進階範例
從包含參數 ?post_id=任何數字的 URL 顯示貼文 ID 的標題：[vg_display_data object_id_type="query_string" object_id="post_id" key="post_title" data_source="post_data"]
從 PHP 函式取得文章或使用者 ID：[vg_display_data object_id_type="callable" object_id="function_name" key="post_title" data_source="post_data"]
使用電話號碼 = 1234（meta_key=phone AND meta_value=1234）取得目前使用者的電子郵件：[vg_display_data object_id_type="find" object_id="phone:1234" key="user_email" data_source="user_data"]
參數
object_id = 文章 ID。如果留空，則使用目前的文章。可能的值：（留空）、current、數字、如果 object_id_type=query_string，則為查詢字串鍵；如果 object_id_type=callable，則為函式名稱；如果 object_id_type=find，則為 meta_key:meta_value
object_id_type = 如果 object_id 為空、current 或為數字，則留空。可能的值：query_string，callable，find
data_source = 用於查找資料的資料庫表。預設為 post_meta。可能的值：post_data、post_meta、user_data、user_meta、post_terms。
key = 欄位鍵值。可接受一個或多個以逗號分隔的鍵值。例如，要顯示全名=first_name,last_name。必填。
template = 用於顯示欄位的 HTML 片段。如果欄位為空，則不顯示 HTML。可選。
default = 如果欄位為空，使用的預設值。可選。
joiner = 如果欄位有多個值，則會使用此項目。可選。

原文外掛簡介
UPDATE
Our plugin now includes a settings page where you must whitelist every field that you want our shortcode to display in the front end, for security reasons. Your existing shortcodes will not work until you whitelist those field keys.
The “sanitization” parameter has been removed. All the output is sanitized with wp_kses_post always.
The “wp_filter” parameter has been removed. Now we have more specific parameters like wpautop=”yes” to turn line breaks into paragraphs, and do_shortcodes=”yes” to parse shortcodes.
Display post and user custom fields data anywhere on the frontend using a shortcode, including advanced custom fields (ACF) fields.
