function uc_product_view_ajax_commands in Ubercart 7.3

Same name and namespace in other branches

1. 8.4 uc_product/uc_product.module \uc_product_view_ajax_commands()

Dynamically replaces parts of a product view based on form input.

If a module adds an input field to the add-to-cart form which affects some aspect of a product (e.g. display price or weight), it should attach an #ajax callback to that form element, and use this function in the callback to build updated content for the affected fields.

Parameters

$form_state: The current form state. This must contain a 'variant' entry in the 'storage' array which represents the product as configured by user input data. In most cases, this is provided automatically by uc_product_add_to_cart_form_validate().

$keys: An array of keys in the built product content which should be replaced (e.g. 'display_price').

Return value

An array of Ajax commands.
