I am using the SiteMapModule, so it will be a little different for you, but in the module, there is a makeChildList function for creating the nested links. I passed an additional parameter to this function for the parent page's url, which I called $parentURL which I amended to the beginning of the href tag as shown below:
If you are upgrading a site just don't add "SiteTree::enable_nested_urls()" to your config file and the URLs will stay the same as your old 2.3 site. Keep in mind that users are automatically redirected from old non-nested URLs to new nested URLs if you do enable them.
I've got my sitemap working, but is there any way for it to include the image galleries within a gallery page?
For example, the sitemap includes "bikes" which is a gallery page, but I would also like it to include the galleries titles within that.
I suspect that, since this will probably require db queries to the image gallery data, that it might not be a trivial task?
Any pointers on where to start looking? My php is rusty at best, but I know my way around MySQL.
