First product variant always being added to cart (Venture Theme)

Technical Q&A

Topic summary

A Shopify store using the Venture theme has a cart issue: whichever product variant is selected on the product page, the cart always adds or displays the first variant instead.

  • The problem is reported during setup of a friend’s store, and appears tied to the product form in product-template.liquid.
  • A code snippet is included and is central to the question. It shows current_variant = product.selected_or_first_available_variant, plus the product form generated with {% form 'product', product %}.
  • The visible option selectors are incomplete in the shared snippet, so the likely area of concern is whether the variant picker and hidden variant id input are correctly rendered and updated.

Current status:

  • No fix is provided in the shared discussion.
  • The issue remains unresolved and open.
  • Key unanswered question: whether the Venture theme’s JavaScript or missing form inputs are preventing the selected variant from being submitted, causing Shopify to default to the first variant.

Hi there,

I’m new to Shopify platform.

I’m recently helping my friend on his store, and there is an issue that I found and couldn’t be solved (Venture Theme)

No matter which Variant is selected, after adding a Variant to the cart, the cart always show the first Variant.

I tried to search in the community and google, seems this issue happens to some other people but never solved.

Could anyone help?

Thanks

Here is the product-template.liquid
