ブログ記事内やページ内で特定の記述をした部分を特定のhtmlへ変換する機能。

https://github.com/culturekings/shopify-shortcodes
のshortcode-render.liquidとshortcode.liquidをassetsフォルダへ配置

　
templates/article.liquid の記事部分を下記へ書き換える

{% include 'shortcode' load:article.content %}

　
記事編集で下記コードを入力する。xxxxの部分は商品ハンドル

[product_in_blog handle="xxxx"]

　
「product_in_blog」という名称のショートコードを作成する時は、「shortcode-product_in_blog.liquid」というファイルを作成する。

　
引数「handle」を設定する場合、「shortcode-product_in_blog.liquid」で値を取得する処理は下記。

{%- capture product_handle -%}{%- include 'shortcode-render' render:'handle' default:'' -%}{%- endcapture -%}
