Following is a rewrite of action.php (in detail, a rewrite of handle_parser_wikitext_preprocess). Enhancements are:

1. Support for non default storage path for data, especially for farms. Uses Dokuwiki functions instead of custom written
2. Support for inheritance, using __header.txt and __footer.txt (two underscores). Mechanism is same and the implementation is based on code for namespace_templates
3. Support for replacement patterns as shown here.

The plugins below is rewrite and enhanced:
HeaderFooter Enhanced

To add header or footer text to pages in a namespace, you need to create a file named _header.txt or _footer.txt in the namespace directory (root namespace is under data/pages), which contains all you need to add. Then, put the file in a namespace. It's all! Easy enough ? Yes, just like what the page template does!

• Remember: the _header.txt and _footer.txt support the same markup syntax as you use in any common wiki page.
• Be careful for using head line, because we don't want to see any “EDIT” button in the suplus text.
• Currently in a namespace, only the same level pages are influenced by _header.txt or _footer.txt, subdirectories are not influenced. (If needed, just put the same _header.txt/_footer.txt in subdirectories)
• For some non-English languages, think of the files' encoding. UTF-8 is preferable.

• The most common reason is that due to the page cache, your page will delay to correctly display the newest version. A convenient way is that closing the plugin in plugin management and reopen it again. It'll refresh the cache. Another way to refresh a page is to add the parameter purge to the URL. Example:

  http://www.example.com/namespace/page?purge=true

• Be sure that your pages and _header.txt/_footer.txt are in the same level directory.
