// This is included by the program instantiating the UpdateSite class via updatesite.class.php

// The Ajax part does not need the UpdateSite class.
  // This part reads the 'page' file and replaces the '// START UpdateSite ...' marker with an array that fills the $item rather
  // than filling it via the $u->getItem() function.

session_start(); // Start the session for the ajax part!

  // The function part of this file sets up these session variables.

// Remove the Admin Notice.

$data = preg_replace('/if\(\$S->isAdmin.*?}/s', "", $data, 1);
// This works using an eval!
  // I want the file to actually execute the PHP in it. That is execute it just like if
  // the file was loaded via the server. All of the PHP in the file is executed and the
  // results is output.

// This file is included in the site specific updatesite2.php (or whatever it is called -- the second part of the site specific
// pair of files).
// This function is then called from updatesite.class.php (UpdateSite class) 'previewpage' function. 'previewpage' check to see
// that the function exists. If it does not exist then a message is presented and the user is given the option to proceed to the
// post page without a preview option.
// If this function does exist it is passed the "$this" of the UpdateSite class, the id of the item, the page name, itemname, and
// the title and bodytext text.
// This function then starts a session and sets the session variables for the AJAX part above.
// It then presents an <iframe> that is filled via the AJAX logic and a form that has a 'create' and 'discard' button.
// The iframe has the full page of the 'page' file with the insert.
// The AJAX ifram is '<iframe id="frame" style="width: 100%; height: 100%;" src="$self?ajax=1"></iframe>'. The Javascript in the
// header handles the Ajax and the buttons.
