Caution: This is an advanced tutorial and is not supported by Shopify. This tutorial has been verified to work with Debut theme only. You can try to implement this on your theme, but keep in mind that it may not function. Knowledge of technologies such as HTML, CSS, JavaScript, and Shopify Liquid is required. We suggest hiring a Shopify Expert if you are not comfortable proceeding with the following tutorial. 

Once you have completed the steps in this tutorial, the custom video will appear as a custom block on your products pages: 

Check out this demo product to see the tutorial result in action.

Step 1. Create a new Shopify Liquid snippet called custom-video.liquid

  1. From your Shopify admin, go to Online Store > Themes.

  1. Find your current theme (or the theme you want to edit) and then click Actions > Edit code.

  1. On the left side, click the Snippets heading to access your Snippets. Once you get the list of snippets, click the Add a new snippet link.

  1. Name your snippet custom-video. Click Create snippet:

  1. Copy and paste the code listed below into your new ‘custom-video.liquid’ snippet.

 <div class="custom-video-wrapper">
 {%assign custom_videos = product.metafields.custom-video %}
  {%if custom_videos.size > 0 %}  
   <h3>Check out the video guide</h3>    
     {% for file in custom_videos %}
      {% assign file_key = file | first %}
      {% assign file_link = file | last %}
      {% assign file_link = file_link | replace: '/watch?v=', '/embed/'%}
       <iframe width="560" height="315" src="{{file_link}}" frameborder="0"></iframe>

Save the file. 

Step 2. Include custom-video.liquid in your product-template.liquid

  1. On the left side of the screen (same section we used to find the Snippets), click the Sections heading to access your Sections.


  1. Under the Sections heading, locate and click product-template.liquid to open your product template in Shopify built-in online code editor.

  2. Find the perfect spot to place your custom video block within the product page. In this tutorial we’ll place it right under the product description. Find the following block of your product-template.liquid file: 


  1. copy and paste the code listed below right under the product description section:

{% render "custom-video" %}

  1. Proudly hit Save button:

Step 3. Add CSS styles (optional).

Now you may want to add some CSS rules to make the whole thing look pretty. Go to Assets section and find your theme.scss.liquid file


Open this file and add some really cool styling to the classes used in our tutorial: "custom-video-wrapper”

Have fun :)

Step 4. Populate the metafields.

The custom functionality we implemented earlier is pretty easy to use and maintain. All you need to do to add a new video block to your product is to create create a new metafield within the namespace specified in your custom-video.liquid Snippet file (the default namespace used in this tutorial is “custom-video”). The key of the metafield may be any valid and unique key. The value of the metafield should contain a valid URL of the video you want to display at the product page. For example, this is what the metafields used to add the custom relations for our demo product look like “under the hood”:
