[pmwiki-users] Don't allow saving guest post for 0 modification

[Dominique Faure]

Hi,

A solution could be to handle this in the same way it is already done with
author requirement: Looking at scripts/author.php, you'll could easily see
that the form post is interrupted by setting the $EnablePost variable to 0;

Have a try with the following code:

array_unshift($EditFunctions, "DeltaPageContent");
function DeltaPagecontent($pagename,&$page,&$new) {
  global $EnablePost, $ModifiedPageContentRequiredFmt;
  if (!$EnablePost) return;

  if ($new['text'] != $page['text']) {
    SDV($ModifiedPageContentRequiredFmt, "<h3 class='wikimessage'>$[The
page hasn't been modified.]</h3>");
    $MessagesFmt[] = $ModifiedPageContentRequiredFmt;
    $EnablePost = 0;
  }
}

Regards,
Dominique
