SaveTo Wishlist and Advanced Product Fields work together to ensure your customers always purchase fully configured items. Many products require specific choices before they can be bought, such as an engraving, an uploaded file, or a custom size. However, adding these items directly from a wishlist to the cart normally skips these required steps.
To handle add-on products safely, this integration flags any wishlist product that carries Advanced Product Fields option fields as needing configuration. Instead of adding an incomplete item straight to the cart or failing, the wishlist automatically routes the shopper back to the product page. There, they can fill in the required fields and add the product to the cart fully configured, so nothing important is skipped.
This helpful routing works completely automatically out of the box with zero settings to configure. It also works efficiently in the background—only products that actually carry option fields are flagged, so all your standard items still add to the cart as usual. Plus, data lookups are cached per request to keep your site fast even on long wishlists.
