LW Postcode Autofill for WooCommerce

想無痛提升轉換率？讓結帳一氣呵成就可以！LW Postcode Autofill for WooCommerce 是專為台灣 WooCommerce 商店設計的結帳小幫手。結帳時僅輸入 3 碼郵遞區號，系統自動帶入縣市與鄉鎮市區，更直覺且大幅降低人工輸入錯誤。

現在支援台灣、香港、澳門、馬來西亞、新加坡，不支援的國家或地區會維持 WooCommerce 原生地址流程，不強制套用台灣地址格式。

此版本主要支援 WooCommerce Classic Checkout，保留原本的結帳、付款與訂單流程。WooCommerce Checkout Blocks are not currently supported.

LW Postcode Autofill for WooCommerce does not modify the WooCommerce payment flow, does not change Apple Pay behavior, does not change LINE Pay or credit card payment lifecycles, does not modify order status lifecycle, and keeps WooCommerce HPOS compatibility declarations intact.

If WooCommerce is not active, if the checkout type cannot be confirmed, or if the checkout page uses Checkout Block, the helper stays conservative and does not load classic checkout field logic.

Key behavior:

• Taiwan shoppers can enter a 3-digit postcode to autofill city and district.
• Singapore and Malaysia postcode validation stays focused on the expected local postcode length.
• Unsupported countries fall back to WooCommerce native address fields.
• CVS pickup address requirements are kept separate so store-pickup flows can remain owned by the CVS pickup plugin.
• Payment gateways continue to own payment sheet, authorization, failure, and success behavior.

Features

• Mobile friendly checkout field behavior.
