How can I get the checkboxes to update the price and register when added to the cart in Webflow using jQuery or any other method?

To dynamically update a price based on checkboxes and send that updated price to the Webflow eCommerce cart, you’ll need a custom solution using jQuery or vanilla JavaScript, because Webflow’s eCommerce doesn’t support this natively.

Here's how you can do it:

1. Understand the Limitation

• Webflow’s native eCommerce system does not support custom prices calculated on the fly on the front end.
• Product prices are fixed based on what you set in the CMS or product list.
• Custom logic like checkboxes for add-ons or options requires JavaScript to handle calculation and cart “hacks”.

2. Set Up Your Product with Base Price

• Create a product normally in Webflow.
• Assign a base price without add-ons.
• Place checkboxes (outside or inside the product form) using standard form elements (Checkbox fields, not tied to Webflow’s variant system).

3. Use Hidden Custom Fields For Add-ons

• Add checkboxes for each add-on option.
• Use custom text fields (hidden) or JavaScript variables to track total price changes.

4. Use jQuery to Update Price on Checkbox Change

In your Page Settings → Before custom code, add a script like this:

<script>$(document).ready(function () {  let basePrice = 100; // Replace with your actual base product price  let totalAddons = 0;  // Update displayed price  function updateTotalPrice() {    let totalPrice = basePrice + totalAddons;    $('.product-price').text('$' + totalPrice.toFixed(2));  }  $('.addon-checkbox').change(function () {    let addonPrice = parseFloat($(this).attr('data-price'));    if ($(this).is(':checked')) {      totalAddons += addonPrice;    } else {      totalAddons -= addonPrice;    }    updateTotalPrice();  });});</script>

• .product-price is the class where the final price is shown.
• .addon-checkbox is the class for each checkbox.
• Ensure each checkbox has a data-price attribute, like data-price="10".

5. Send Custom Price/Data to the Cart

Because Webflow doesn’t let you change product price dynamically at checkout, you have two workarounds:

• Option A: Use Webflow forms only (no eCommerce): Submit as a form, collect selections and price, and process offline or via an automation (e.g., Zapier + Stripe).
• Option B: Fake Variants with Price Tiers: Create multiple fake variants in Webflow CMS to reflect possible combinations. Then, use JavaScript to trigger the variant that matches the selected combo.

Webflow cart doesn’t support custom pricing directly from JS, so this is a common workaround.

6. (Optional) Track Selections in Cart Note or Custom Attributes

You can push checkbox selections into the "Note" field of the cart item using JavaScript by pre-filling a text input.

$('.form-note-input').val('Addon A: Yes, Addon B: No');

Replace .form-note-input with the correct selector for a hidden input or a visible field in the product form.

Summary

To reflect checkbox selections in total price:

• Use JavaScript (like jQuery) to dynamically calculate updated prices.
• Display the new price on the page using DOM manipulation.
• Send limited data to the cart using fake variants or hidden fields (due to Webflow’s pricing structure limitations).
• For full flexibility, consider Webflow forms + external payment processor (e.g., Stripe via Zapier/Make).

Let me know if you want code for fake variant selection or Zapier integration too.
