function hook_cart_display in Ubercart 5

Same name and namespace in other branches

1. 6.2 docs/hooks.php \hook_cart_display()

Control the display of an item in the cart.

Product type modules allow the creation of nodes that can be added to the cart. The cart determines how they are displayed through this hook. This is especially important for product kits, because it may be displayed as a single unit in the cart even though it is represented as several items.

Parameters

$item: The item in the cart to display.

Return value

A form array containing the following elements:

• "nid"
  • #type: value
  • #value: The node id of the $item.
• "module"
  • #type: value
  • #value: The module implementing this hook and the node represented by $item.
• "remove"
  • #type: checkbox
  • #value: If selected, removes the $item from the cart.
• "options"
  • #type: markup
  • #value: Themed markup (usually an unordered list) displaying extra information.
• "title"
  • #type: markup
  • #value: The displayed title of the $item.
• "#total"
  • "type": float
  • "value": Numeric price of $item. Notice the '#' signifying that this is not a form element but just a value stored in the form array.
• "data"
  • #type: hidden
  • #value: The serialized $item->data.
• "qty"
  • #type: textfield
  • #value: The quantity of $item in the cart. When "Update cart" is clicked, the customer's input is saved to the cart.
