I would like to use article names which contains "/" (slash) and/or "\" (backslash).
how to do this?
# Enable subpages in the main namespace $wgNamespacesWithSubpages[NS_MAIN] = true;
If you do this,
Media/Wiki will be a subpage of "Media" and it will show a link to the parent page under the page title (like this):
By default, MediaWiki enables subpages for all namespaces except main (ns0).
About page titles, the MediaWiki manual says:
It's not possible to use forward slashes in the title of a page from a namespace where subpages are activated, however back slashes (
\) are treated as normal characters in subpage naming and can be used in place of forward slashes.
