Can I make Getsimple actualize sitemap entries manually?

[Carlos]

Small plugin that adds a "Update Sitemap" button to the Page management sidebar:

Code:

<?php

$thisfile = basename(__FILE__, ".php");

register_plugin(
  $thisfile,
  'Sitemap Update',
  '0.1',
  'Carlos',
  '#',
  '...',
  'pages',
  'sitemap_update'
);

add_action('pages-sidebar', 'createSideMenu', array($thisfile, 'Update Sitemap'));

function sitemap_update() {
  create_pagesxml(true);
  generate_sitemap();
  echo 'Sitemap updated.';
}

// end

Save as sitemap_update.php in plugins folder, then activate.
