原文外掛簡介
Zevvo File Upload for WooCommerce allows your customers to upload files directly on product pages and have those files automatically attached to their orders. Whether you run a print-on-demand store, a custom gift shop, or any business that needs customer-supplied files, Zevvo handles it securely and smoothly.
Built from the ground up for HPOS (High-Performance Order Storage) compatibility, it works with both the classic and block-based WooCommerce cart and checkout.
