I want to be able to inject fields from one post into another using a shortcode. I thought a good way to do this would be to have the user insert a link to the page, like this:
[shortcode]Link - to - http://example.com/taxonomy/term/post-name[/shortcode]
I want to parse that link using something like
WP->parse_request(), however that won't do it. How can I parse a URL and get its post (or even just its ID)?
Is there another way to inject one post's content into an arbitrary point in another?
