Working with Google Sitemap through the product interface is described in the help:
But to perform this task according to a schedule we'll make a script based on the CSiteMap::Create() method:
Code
CSiteMap::Create ($site_id, $max_execution_time, $NS, $arOptions = array()) |
This method requires the following parameters:
- site_id - ID of the site for which the sitemap will be generated
- max_execution_time - an array. First element is the max step time in seconds. Second element - max number of search index records (value less than 5000 is recommended).
- NS - Step start value. The result of previous iteration should be passed to this parameter.
- arOptions - Optional. If this contains the key 'FORUM_TOPICS_ONLY' with value Y, then only the topics’ starting messages fr om the forum will be added to the sitemap.
Sitemap generation is always performed in a step-by-step manner. After one step is performed, the process receives the results of the previous step and proceeds.
The script itself with comments:
Code
<?
//specify your real 'DOCUMENT_ROOT' directory path
$_SERVER["DOCUMENT_ROOT"] = realpath(dirname(__FILE__)."/. ./..");
define("NO_KEEP_STATISTIC", true);
define("NOT_CHECK_PERMISSIONS",true);
require($_SERVER["DOCUMENT_ROOT"]."/bitrix/modules/main/include/prolog_before.php");
@set_time_limit(0);
@ignore_user_abort(true);
//including 'search' module
if(CModule::IncludeModule('search'))
{
//this will be an array containing temporary data
$NS=Array();
//two parameters should be defined:
//1. max length of the iteration. If equal to zero then no limit for the iteration time is applied
//2. maximum number of links processed during one step. Should not be too big otherwise it'll reduce script performance
$sm_max_execution_time = 0;
$sm_record_lim it = 5000;
do {
$cSiteMap = new CSiteMap;
//perform the iteration
$NS = $cSiteMap->Create("s1", array($sm_max_execution_time, $sm_record_lim it), $NS);
//CSiteMap::Create method returns array if another interation is necessary.
//It returns 'true' or 'false' if process has or hasn't been finished successfully
} while(is_array($NS));
}
require($_SERVER["DOCUMENT_ROOT"]."/bitrix/modules/main/include/epilog_after.php");
?>

We'll place this file in the /bitrix/php_interface/ folder. Now, all that is left is to set up 'cron' to launch it periodically.
As this method for creating a Sitemap doesn’t have an internal check to prevent it from running the same task several times at once, it's recommended to run the script once a day (or less frequently), preferably at a time when the number of visitors is minimal.
For example, the following crontab line will launch this script at midnight every day:
Code
0 0 * * * /usr/bin/php -f /var/www/bitrix/php_interface/sitemap_generation.php |
You may need to change the path to the PHP on your server as well as the DOCUMENT_ROOT path to your server document root folder to make script work in your environment.
