Nutrition Facts Label

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.

 <?php echo do_shortcode( '[embed_nutrition_label]' ) ?> 

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.

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.
