2019-05-05 Revised order of events:

  • PHASE I: receive
    • detect submitted page - $this->GetPageKey_forData();
    • load controls to receive that
    • receive form data
    • save form data
      • save back to blob -- the Cart should save the blob field on return
  • PHASE II: display
    • determine page to show - $this->HandlePageRequest();
      • calculate if requested page should be displayed (if any required fields are missing, can't advance)
    • load controls to display that
    • load any saved values from blob
    • DON'T display the page because that is handled by the vcPageContent_ckout::Render() event.

Old notes:


  • 2019-05-22 This has been renamed to DoPage() and substantially rewritten; other related objects gutted
  • 2019-05-05 Order of events revised
  • 2019-04-27 old notes archived



      PURPOSE: core form processing & page rendering
	* 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
	  * 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.
