I am trying my hand at Wordpress plugin development. From all of the getting started examples and tutorials I have seen, it seems as though plugins can do little more than, say, add a "Bookmark This" at the end of a post, add an icon next to external links, or other relatively minor enhancements to existing features.
I would like to develop an extension (might that be the better word?) where a user can go to my-wordpress-site.com/the-extension
and access the features of the web application. However, since all extensions must placed within wp-includes/plugins/the-extension
, does that mean that is the only way the plugins can be accessed?
How could I design the extension and containing pages to be accessed with a URL like this: my-wordpress-site.com/the-extension
?
