A preview begins with "Page is unsaved". That makes sense for "Preview", but
would be confusing for "Save and edit".
Unless someone can suggest a better way, I'd create markup for a conditional
test so the edit form can ask whether the request was "postedit". Something
like this:
$Conditions['savingwithpreview'] = 'SavingWithPreview()';
function SavingWithPreview()
{
return (@$_REQUEST['postedit']>'')
}
Then on the edit form I'd put (:if savingwithpreview:) Page is unsaved (:ifend:)
This raises a question that I've been meaning to ask anyway: does adding custom
conditional tests or custom page variables slow PmWiki's processing? If it
doesn't slow my already slow wiki, I can think of all sorts of ways I might
want to use them.
