Offering the subscription option on specific variants

Recharge typically applies a subscription rule to an entire product, including the variants. However, you may need to offer a subscription on just one or multiple variants of the product. This can be implemented using custom coding within the subscription-product.liquid snippet in your Recharge theme files.

This guide is not a step-by-step tutorial but provides general advice on implementing this customization. 

Before you start

• This customization requires Shopify Liquid and JavaScript knowledge. This customization is not supported by Recharge as per the Recharge design policy.
• Consider working with a Recharge Agency Partner to implement this change, as each theme is different and may require additional troubleshooting. 
• This is a complex implementation that requires the use of JavaScript. You may want to consider an alternative, less intensive build such as building a custom page from scratch using AJAX, or separating the variants as standalone products.

General implementation

Step 1 - Create JavaScript Function

1. Create a function that receives the specific variant name for the product variant from your store.
2. Perform a string match to assets to see if the value matches a variable that you have created.
   1. If the values match, both the one-time and subscription options are displayed when selected by the customer.
   2. If the values do not match, the code automatically hides both options and selects one-time in the background so that these variants cannot be added to the cart as a subscription product. When the product page is fully loaded, the code hides the one-time and subscription options until the specified variant is selected.

Step 2 - Define a listener

You must define a listener to trigger if the variant is changed. You will also need to create this listener according to the needs of your specific theme. For example:

• If you have a dropdown with the product variants you must add the ID and class into the listener and use the change function. The change function takes the name of the selected variant as a parameter in the embedded check_variant_name function to know whether to show or hide the subscription options accordingly.
• If you use buttons to select variants you must use the click function for the listener.

The script must also check whether the default variant that is pre-selected should show the subscription options or not. This is needed as the variant can be selected via a URL. 

If the variant is selected via a URL, it must be validated by the selected variant name. Use the check_variant_name function with the variant name set as a parameter to show/hide the subscription options accordingly.

Ensure that when you use the show/hide action on the radio buttons to re-check the one-time purchase radio option in case someone has the subscribe option checked and they switch it back to a non-subscription product.

Verify the JavaScript and trigger theonClickevent as well.

You can also modify your code above to support more than one variant by adjusting the variants included in the snippet.
