Cart, wishlist, and reviews

Visitor commerce state, discounts, wishlist items, and shopper-visible reviews.

These pages list the exact data fields available to hosted Vascula themes. Add a root name such as product to a section's ctx_needs, then read it directly as product.title in the template. The ctx. prefix shown here identifies the public contract; do not include that prefix in a Vascula expression. Required fields are present whenever their containing object is present. Optional fields may be absent, and nullable fields may be present as null. [] marks an array item and {key} marks a key selected at runtime. Named types such as Price and Media are detailed on Shared data shapes.
