I have a simple php script that updates my sitemap automatically. However, when you click the link to the sitemap at www.bomstudies.com/sitemap-xml.php - the last mod date is showing 1969. The php script works for files that are not in sub folders. such as /talks or /commentary. I just need to know what snippet of code i should add, change, or delete to the sitemap php side of it to show the correct last mod date for my xml sitemap. I greatly appreciate your help. Thanks - Here is some of my code: The Config Code: posted as config.php <?php /** * Change the configuration below and rename this file to config.php */ /* * The directory to check. * Make sure the DIR ends ups in the Sitemap Dir URL below, otherwise the links to files will be broken! */ define( 'SITEMAP_DIR', './'); // With trailing slash! define( 'SITEMAP_DIR_URL', 'http://www.bomstudies.com/' ); // Whether or not the script should check recursively. define( 'RECURSIVE', true ); // The file types, you can just add them on, so 'pdf', 'php' would work $filetypes = array( 'php', 'html', 'pdf', 'doc', 'docx', 'xls', 'xlsx' ); // The replace array, this works as file => replacement, so 'index.php' => '', would make the index.php be listed as just / $replace = array( 'index.php' => '' ); // The XSL file used for styling the sitemap output, make sure this path is relative to the root of the site. $xsl = 'xml-sitemap.xsl'; // The Change Frequency for files, should probably not be 'never', unless you know for sure you'll never change them again. $chfreq = 'weekly'; // The Priority Frequency for files. There's no way to differentiate so it might just as well be 1. $prio = 1; // Ignore array, all files in this array will be: ignored! $ignore = array( 'config.php' ); the xml-sitemap.php page <?php /** * XML Sitemap PHP Script * For more info, see: http://yoast.com/xml-sitemap-php-script/ * Copyright ©, 2011 - 2012 - Joost de Valk, joost@yoast.com */ require './config.php'; // Get the keys so we can check quickly $replace_files = array_keys( $replace ); // Sent the correct header so browsers display properly, with or without XSL. header( 'Content-Type: application/xml' ); echo '<?xml version="1.0" encoding="utf-8"?>' . "\n"; $ignore = array_merge( $ignore, array( '.', '..', 'config.php', 'xml-sitemap.php' ) ); if ( isset( $xsl ) && !empty( $xsl ) ) echo '<?xml-stylesheet type="text/xsl" href="' . SITEMAP_DIR_URL . $xsl . '"?>' . "\n"; function parse_dir( $dir, $url ) { global $ignore, $filetypes, $replace, $chfreq, $prio; $handle = opendir( $dir ); while ( false !== ( $file = readdir( $handle ) ) ) { // Check if this file needs to be ignored, if so, skip it. if ( in_array( utf8_encode( $file ), $ignore ) ) continue; if ( is_dir( $file ) ) { if ( defined( 'RECURSIVE' ) && RECURSIVE ) parse_dir( $file, $url . $file . '/' ); } // Check whether the file has on of the extensions allowed for this XML sitemap $fileinfo = pathinfo( $dir . $file ); if ( in_array( $fileinfo['extension'], $filetypes ) ) { // Create a W3C valid date for use in the XML sitemap based on the file modification time if (filemtime( $dir .'/'. $file )==FALSE) { $mod = date( 'c', filectime( $dir . $file ) ); } else { $mod = date( 'c', filemtime( $dir . $file ) ); } // Replace the file with it's replacement from the settings, if needed. if ( in_array( $file, $replace ) ) $file = $replace[$file]; // Start creating the output ?> <url> <loc><?php echo $url . rawurlencode( $file ); ?></loc> <lastmod><?php echo $mod; ?></lastmod> <changefreq><?php echo $chfreq; ?></changefreq> <priority><?php echo $prio; ?></priority> </url><?php } } closedir( $handle ); } ?> <urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"><?php parse_dir( SITEMAP_DIR, SITEMAP_DIR_URL ); ?> </urlset>
