A short overview of how I understand trackback implementation:
blogA writes a story about blogB
blogA inserts blogB's trackback URL
blogA's software pings blogB's trackback URL
I think this contains blogA entry's URL
blogB's software pingback's blogA's URL to verify the entry's existance
blogB lists blogA's URL as an entry about blogB's entry if pingback success
and also the reverse if blogB writes a story about blogA's entry. blogA
should send a pingback to blogB's URL if it gets a trackback ping from it.
So...
I'm using MediaWiki 1.5.5, which is just a php-based wiki software.
This version of MediaWiki that I am using includes the code to handle
the incoming trackback pings already. If a blog writes an entry about a
page in the wiki, it can use the wiki page's trackback URL to ping the
wiki page it refers to. MediaWiki will list the blog that referred to
it at the bottom of the page.
So this is good to go, but MediaWiki does not provide the functionality
to ping the trackback URL of another website. I dabble in PHP a bit,
and don't think it would be too difficult to add this feature to
MediaWiki at all, but I'm not sure about the guts of trackback pinging
functions. Like I was saying, I think that you have to have:
(A) The URL to ping
(B) The URL of the wiki page / blog entry which will refer to it
(C) Something to respond to the pingback, if sent (some trackbacks don't
pingback) (and I'm not sure if you even have to send something back when
you get pingbacked - it might just be checking to see if it is a webpage
and that it loads, I'm not sure)
The main part of the code, I don't see much of a problem with. I would
write a function that takes the URLs as parameters. The only thing I'm
not sure about is what exactly to send the trackback url when I ping it.
Any help would be appreciated.
