If you want to display the entered data with error messages, you simply
display the form that failed validation. So remove the else leg of if
pform.is_valid(), where you replace the form that failed validation with a
blank one. (It's also common practice to return an HttpResponseRedirect in
the case where the post and save was successful, which you don't seem to be
doing, meaning the input form is going to be re-displayed even in the case
where there were no errors.)
What you want is something more like:
def getInfo(request):
if request.method == POST:
pform = PersonForm(request.POST)
if pform.is_valid():
pform.save()
return
HttpResponseRedirect('/your_url_for_successful_post')
else:
pform = PersonForm()
return render_to_response("person.html",{"form":pform})
