內容簡介
我們發佈這個外掛的動機是基於在食品烹調主題支援網站的論壇討論。
我們認為我們已經有一些能夠作為產生該外掛基礎的代碼，其他美食部落客可以從中受益甚至可能改進。
這個外掛適用於使用食品烹調主題的博客網誌。
對於非基於食品烹調主題的美食部落格，可以建立一個名為“recipe”的自定義文章類型，並在其中加入一個元數據項，其鍵值為“RECIPE_META_ingredients”。
我們強烈建議選擇這種方法或在WordPress開發人員的指導下使用這個外掛。
從技術方面來看，為了生成營養成分標籤，您可以生成一個圖像或生成一個帖子元數據鍵（gfb_recipe_meta_nutrition_facts），該鍵保存了JSON數據（每個食譜）用於生成營養標籤。
這個外掛還在管理區中的食譜帖子編輯頁面中包含一個元數據框，該框自動讀取關鍵為“RECIPE_META_ingredients”的元數據項，該項主要包含您的配料清單，並使用它來生成營養標籤。
為了自動顯示每個食譜的營養標籤，您的WordPress開發人員應將此代碼添加到最佳位置。
<?php echo do_shortcode( '[embed_nutrition_label]' ) ?>
也可以從文字編輯器中嵌入短代码。
但基於食品烹調食譜頁面佈局的限制，您的選擇可能會受到限制，因此最好由WordPress開發人員在此幫助。

影片教學
這個外掛為美食部落客提供了在他們的食譜帖子中添加營養成分標籤的能力。
這個外掛提供圖像下載選項或短碼作為分享營養見解的可能方法。它還提供了一個更新設施，可以為已有的食譜帖子添加營養成分標籤。
非常感謝nutritionix的人分享他們在javascript nutrition label 的使用，我們對此進行了微調並使用了它們。
我們在www.globalfoodbook.com 是開源和敏捷的倡導者。我們在github 上公開了這個外掛，並將繼續改進它。
我們感謝使用其他外掛而獲得的幫助，並希望能夠在每一個可能的機會貢獻給這個令人驚嘆的WordPress社區。
目前，我們正在努力改進後端算法，如果您有興趣可以加入我們。
我們希望聽到您對此有何改進方式。您可以通過我們的網站或電子郵件（we [at] globalfoodbook.com）聯繫我們。
謝謝。

原文外掛簡介
Our motivation for releasing this plugin is based on a forum discussion on the food-cook theme support site.
We felt that we already had some code that could serve as a basis for producing this plugin, other food bloggers could benefit and possibly improve on.
This plugin will work best on blogs that use food-cook theme.
For food blogs that are not based on the food-cook theme, It is possible to create a custom post type called “recipe” and an ingredients post_meta entry with key “RECIPE_META_ingredients”.
We strongly recommended taking this route or using this plugin under the guidance of a WordPress developer.
From a more technical side, In order to generate a nutrition facts label, you can either generate an image or generate a post_meta key (gfb_recipe_meta_nutrition_facts) that holds JSON data (for each recipe) which is used to generate a nutrition label.
This plugin also includes a meta box within the recipe post edit page in the admin area, which automatically reads the post_meta entry with key “RECIPE_META_ingredients” which mainly contains your ingredients list and uses that to generate the nutrition label.
In order to automatically display a nutrition label on the every recipe, your WordPress developer should add this line of code to the best possible place.
It is also possible to embed this as a short-code from the text editor.
But based on the food-cook recipe page layout your options may appear limited, hence why it is best that a WordPress developer helps out here.

How to Video
This plugin provides food bloggers with the ability to add a nutrition facts label to their recipe post(s).
This plugin provides image download option or short-codes as possible ways of sharing nutritive insights. It also provides an update facility that adds a nutrition facts label to already existing recipe posts.
Big thanks to the guys at nutritionix for sharing their javascript nutrition label which we have tweaked and used here.
We at www.globalfoodbook.com are open source and agile proponents. We have open sourced this plugin on github and will continue to improve this.
We appreciate the help we have received from using other plugins and would like to contribute back to this awesome WordPress community at every chance possible.
At the moment we are working on improving our algorithms on the backend and would like it if you could join us.
We would love to hear from you on ways this can be improved, give us a shout via the our website or via email (we [at] globalfoodbook.com).
Thanks
