Ck editor - server preview?

We do something similar, except that we have a preview link on the page loading the editor. This approach can be used for a button in the editor, but this requires additional coding (I will describe this approach below).

The preview link looks something like this:

<a href="#" onclick="return doPreview();">Preview the page</a>

We have a doPreview function:

function doPreview() {
var hiddenForm = document.forms[ 'hidden_form' ];

// TextareaId is the id of the textarea being replaced with CKEditor (the instance name)
hiddenForm.elements[ 'preview_content' ].value = CKEDITOR.instances.TextareaId.getData();

// "myform" is the active form that contains the textarea replaced by CKEditor.
var liveForm = document.forms[ 'myform' ];
if ( ! liveForm ) {
  alert( 'Error finding "myform" form.' );
  return false;
}

hiddenForm.submit();

return true;

}

Finally, there is a form with hidden fields (hiddenForm):

<form name="hiddenForm" action="HTTP://www.yoursite.com/preview_template" method="POST" target="_blank">
  <input type="hidden" name="preview_content" value="" />
</form>

, doPreview.
CKEditor .
.
.
$_POST ['preview_content'] ( ).
