Create dynamic sitemap, humans.txt and robots.txt files

Most of the method described in this tutorial is ported into a new module for CMS Made Simple named SitemapMgr! Read all about is in this tutorial: How to use SitemapMgr »

To help search engines like Bing and Google index your website you can use sitemaps and a robots.txt file. A module like SiteMapMadeSimple is a great solution to create your static sitemap. A disadvantage of the module is that after each content change the sitemap file is recreated. For very large websites it can take a while...

I had that problem at one of my own websites. A few hundred pages, a few thousand Products entries, dozens of news articles and a few dozen Company Directory entries. Working in the admin wasn't fun anymore because the admin was very slowwww. In the CMSMS forum I found some posts from SjG, Kermit and Arnoud talking about dynamic sitemaps. I liked the idea and worked it out for myself, resulting in good SEO-friendly sitemaps and an admin panel in normal speed.

How to use

Required preparations

1. Create a new User Defined Tag named "content_type"

$content_type = get_parameter_value($params,'type');
if ($content_type != '') { cmsms()->set_content_type($content_type); }

2. Create a new Core::Page template named "blank", that only contains:

{content}

3. For each sitemap you want to create, you need to make a regular content page. To keep the listcontent page a bit tidy I put them all under a dummy page or section header.

Parent page or section header: SEO
- Humans.txt
- Robots.txt
- Sitemap Index
- Sitemap Pages
- Sitemap News
- Sitemap CGBlog
- Etc.

In the options tab of the page editor, all pages must be set non-searchable, not in menu and WYSIWYG switched off.
I will show you some example sitemaps, a dynamic robots.txt file and a dynamic humans.txt file.

4. Permissive Smarty

In the latest Smarty releases due to security settings PHP functions aren't available by default... If you do want to use PHP functions, you have to enable them by adding this line to your CMSMS config.php file:

$config['permissive_smarty'] = 1;

This config variable loosens some of the security configuration for Smarty templates. Particularly enabling this option allows the use of any PHP function as a Smarty plugin. You better not use this option if you are allowing content to be submitted for display on your website from untrusted sources!
If the feed reader works without this line, you better not add it!

Sitemap for content pages

Template

Create a new Navigator template named "sitemap_pages" with the content:

<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">

{function name=Nav_sitemap}
{foreach $data as $node}
{page_attr key=searchable page=$node->id assign=isSearchable}
{if $node->type=='content' && !empty($isSearchable)}
<url>
<loc>{$node->url}</loc>
<lastmod>{$node->modified|date_format:'%Y-%m-%d'}</lastmod>
<changefreq>{math now=$smarty.now modified=$node->modified equation='(now-modified)/86400' assign='days'}{if $days < 2}hourly{elseif $days < 14}daily{elseif $days < 61}weekly{elseif $days < 365}monthly{else}yearly{/if}</changefreq>
<priority>{$level=$node->hierarchy|substr_count:'.'}{if $node->url|substr:0:-1 == {root_url}}1{elseif $level == '0'}0.8{elseif $level == '1'}0.6{elseif $level == '2'}0.4{else}0.2{/if}</priority>
</url>
{/if}
{if isset($node->children)}{Nav_sitemap data=$node->children}{/if}
{/foreach}
{/function}

{if isset($nodes)}{Nav_sitemap data=$nodes}{/if}

</urlset>

Page

Create a new content page "Sitemap Pages" with the page content:

{content_type type='text/xml'}
{Navigator template='sitemap_pages'}

All content pages that are included in the menu will be shown in the sitemap, other pages are hidden.
If you want to have them also included you have to add the show_all parameter in the menu call:

{content_type type='text/xml'}
{Navigator template='sitemap_pages' show_all=1}
