I like to hardcode everything on my WordPress websites, without using any plugins. Is there any way to generate or update my sitemap everytime I publish/update a post on one of my Multisite blogs, without using plugins?

You realize that there is no real difference between "hardcode" and a plugin besides the fact the plugins are portable and thus easier to work with? –  Wyck Jan 20 '12 at 18:53

Downvote for the "without a Plugin" restriction. –  Chip Bennett Feb 20 '12 at 17:47
    
Not wanting to add ANOTHER plugin on a CLIENT site is perfectly acceptable for such a simple task. It's true the code is the same but perhaps the OP didn't know that –  jasondavis May 23 '13 at 3:45

I dont know whether this works on multisite or not but it is working perfect for single wordpress installation for me. check it once may be useful for you.

when you create/update any posts or page it will generate sitemap.xml file and update the links (url's) in latest first order (Last modified.)

copy and paste the below code in your active themes functions.php file

    /* function to create sitemap.xml file in root directory of site  */

//add_action("publish_post", "eg_create_sitemap");
//add_action("publish_page", "eg_create_sitemap");

add_action("save_post", "eg_create_sitemap");

function eg_create_sitemap() {
  $postsForSitemap = get_posts(array(
    'numberposts' => -1,
    'orderby' => 'modified',
    'post_type'  => array('post','page'),
    'order'    => 'DESC'
  ));



  $sitemap = '<?xml version="1.0" encoding="UTF-8"?>';

$sitemap .= "\n".'<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">'."\n";


  foreach($postsForSitemap as $post) {
    setup_postdata($post);

$postdate = explode(" ", $post->post_modified);

$sitemap .= "\t".'<url>'."\n".
  "\t\t".'<loc>'. get_permalink($post->ID) .'</loc>'.
  "\n\t\t".'<lastmod>'. $postdate[0] .'</lastmod>'.
  "\n\t\t".'<changefreq>monthly</changefreq>'.
"\n\t".'</url>'."\n";
  }

  $sitemap .= '</urlset>';

  $fp = fopen(ABSPATH . "sitemap.xml", 'w');
  fwrite($fp, $sitemap);
  fclose($fp);
}
?>

Before using this code, I had to make some improvements on it, so follow the accepted standard for XML files. But now it's great and the code goes below:

/* function to create sitemap.xml file in root directory of site  */
//add_action("publish_post", "eg_create_sitemap");
//add_action("publish_page", "eg_create_sitemap");
add_action("save_post", "eg_create_sitemap");
function eg_create_sitemap() {
if(str_replace('-', '', get_option('gmt_offset'))<10) { $tempo = '-0'.str_replace('-', '', get_option('gmt_offset')); } else { $tempo = get_option('gmt_offset'); }
if(strlen($tempo)==3) { $tempo = $tempo.':00'; }
  $postsForSitemap = get_posts(array(
'numberposts' => -1,
'orderby' => 'modified',
'post_type'  => array('post','page'),
'order'=> 'DESC'));
$sitemap .= '<?xml version="1.0" encoding="UTF-8"?>'.'<?xml-stylesheet type="text/xsl" href="' . esc_url( home_url( '/' ) ) . 'sitemap.xsl"?>';
$sitemap .= "\n".'<urlset xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.sitemaps.org/schemas/sitemap/0.9 http://www.sitemaps.org/schemas/sitemap/0.9/sitemap.xsd" xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">'."\n";
$sitemap .= "\t".'<url>'."\n".
  "\t\t".'<loc>'. esc_url( home_url( '/' ) ) .'</loc>'.
  "\n\t\t".'<lastmod>' . date( "Y-m-d\TH:i:s", current_time( 'timestamp', 0 ) ) . $tempo . '</lastmod>'.
  "\n\t\t".'<changefreq>daily</changefreq>'.
    "\n\t\t".'<priority>1.0</priority>'.
"\n\t".'</url>'."\n";
foreach($postsForSitemap as $post) {
setup_postdata($post);
$postdate = explode(" ", $post->post_modified);
$sitemap .= "\t".'<url>'."\n".
  "\t\t".'<loc>'. get_permalink($post->ID) .'</loc>'.
  "\n\t\t".'<lastmod>'. $postdate[0] . 'T' . $postdate[1] . $tempo . '</lastmod>'.
  "\n\t\t".'<changefreq>Weekly</changefreq>'.
    "\n\t\t".'<priority>0.5</priority>'.
"\n\t".'</url>'."\n";
  }
$sitemap .= '</urlset>';
$fp = fopen(ABSPATH . "sitemap.xml", 'w');
  fwrite($fp, $sitemap);
  fclose($fp);
}

Could you please explain your code and file an edit to reformat it for readability? Thanks –  kaiser Jun 23 at 0:10
