[pmwiki-users] Enforce Data Entry on Zap Forms -- Modal Dialogs in PMwiki?

[Sivakatirswami]

Posting again in hopes of some light:
---------

  I'm having  a little problem with ZAP forms
  -- not  specific to ZAP as such any form could have the same issue

  where we need to enforce data entry of all fields and option selections.

  Some users are just  filling in a TO DO form Description field and then
  submitting.
  It gets submitted OK, but with some page variables are empty and
  the pagelists that display the entries don't show them because the
  conditionals are looking for data in fields that are empty.

  How do you alert a the user that
  he needs to fill in a field  before he can finalize submit and then
  return him to the
  form with the data he previous entered still intact in those fields that
  he *did* fill in? I'm used to writing CGI's that do this,  but don't know
    the PMwiki way for data entry enforcement and verification.

  I guess I might as well ask also for  the data type verification snippet
  as well--where  user enters some data that does not meet some criteria...
  and PMwiki needs to respond  with an intelligent user prompt.

  Does  PhP have modal dialogs for PMWiki with an "OK" button to dismiss
  and drop the user back to the page as it was? That would be ideal.
