Notes

2019-04-27 I think what needs to happen is that things need to happen in the following order:

  • detect submitted page - $this->GetPageKey_forData();
  • detect requested page - $this->DetectPageRequest();
  • determine page to show - $this->HandlePageRequest();
    • calculate if requested page should be displayed
  • load all form controls needed to receive submitted & show display page
    • 2019-04-28 probably what needs to happen here is that we need to duplicate the logic of whatever calls vcCartDataManager::GetBuyerObject() et al. (currently includes capturing, rendering, and other stuff) and just create the requisite objects, don't try to use them yet.
    • 2019-05-04 The first problem is to figure out how to make sure that this logic gets invoked during the setup events (KI_NODE_EVENT_DO_BUILDING or KI_NODE_EVENT_DO_FIGURING, not sure which is preferable)
  • receive submitted page - $this->CapturePage($oRes);
  • process submitted page

To examine -- how do the following functions intersect with the above steps?:

  • $this->CapturePage($oRes);
  • $this->HandlePageRequest();

Calls

Code

    /*----
      PURPOSE: core form processing & page rendering
      ACTIONS:
	* dispatches to ParseInput_Login() & HandleInput_Login() to render/handle login controls
	* logs a Cart event to record which page was displayed
	* sets PageKey_forShow()
	* dispatches to RenderPage() to render the page
      HISTORY:
	2018-07-21
	  * ParseInput_Login() and HandleInput_Login() were defined in files which have now
	    been removed from VbzCart. This *should* now be handled automatically by Ferreteria
	    if the right page component class is used.
	  * Also, PageKey_forShow_default() no longer exists; I'm going to assume
	    that we can just use PageKey_forShow().
      TODO: Consider whether maybe this functionality should be moved into $oContent.
