How can I get the currently selected inventory location in liquid?

Topic summary

Goal: Identify, via Liquid (Shopify’s theme templating language), which inventory location (fulfillment/warehouse) is being used for a customer’s order while browsing or on the cart page.

Context: A product exists in two locations, A with 5 units and B with 3 units. Placing an order for quantity 5 would fail if location B is the selected source, so the merchant wants to detect the selected location in advance.

Key ask: Determine if Liquid exposes a variable/object for the currently selected fulfillment location per product or cart line, so quantity validation can reflect the correct location’s stock.

Status: No answers or solutions are provided in the thread. No media or code snippets are included. The question remains open with the main unknown being how (or if) the selected inventory location can be read in Liquid.

When a customer is browsing a store then how can I get which inventory location is being selected when that customer is making order?

Assume a store has product X in two locations: A with 5 units and B with 3 units. Now it’s gonna give me error if I place an order for X product of 5 quantities but the selected inventory is B.

So I need to know which inventory location is being selected for that customer.
