You can add a checkbox to Site.EditForm like this:

   (:input checkbox previewchanges:) Preview changes

Then in config.php, use:


To have a new button instead of a checkbox, in Site.EditForm:

  (:input submit preview "Show changes":)

Then in config.php:

  if(@$_REQUEST['preview']=='Show changes') # same label as the button

If a "reset" button is pressed, all form fields are reset to their default  
content (before any changes).
