uc_checkout_pane_callback

7 uc_cart.api.php uc_checkout_pane_callback($op, $order, $form = NULL, &$form_state = NULL)

Builds and proceses a pane defined by hook_uc_checkout_pane().

Parameters

$op: The operation the pane is performing. Possible values are "view", "process", "review", and "settings".

$order: The order being viewed or edited.

$form: The order's edit form. NULL for non-edit ops.

&$form_state: The form state array of the edit form. NULL for non-edit ops.

Return value

Varies according to the value of $op:

  • view: An array with two keys, "contents" and an optional "description". "contents" is a form array to collect the checkout data for the pane. The description provides help text for the pane as a whole.
  • process: A boolean indicating that checkout should continue. During this op, $order should be modified with the values in $form_state['values']['panes'][PANE_ID].
  • review: An array containing review sections. A review section contains "title" and "data" keys which have HTML to be displayed on the checkout review page.
  • settings: A settings form which can be used with system_settings_form().
