Here’s how to add “post to” links for del.icio.us, digg, and ma.gnolia to individual articles in Textpattern.
Update: Fixed it so the links add urlencoded titles to the output. It’s a bit ugly, but seems to work ok. And I’m having some issues with displaying the PHP code properly, so bear with me.
del.icio.us
post to <a href="http://del.icio.us/post?url=<txp:permlink />&title=<txp:php>$a = title (array ());echo urlencode($a);</txp:php>">del.icio.us
digg
post to <a href="http://www.digg.com/submit?phase=2&url=<txp:permlink />">digg</a>ma.gnolia
post to <a href="http://ma.gnolia.com/bookmarklet/add?url=<txp:permlink />&title=<txp:php>$a = title (array ());echo urlencode($a);</txp:php>">ma.gnolia</a>
Clicking one of the those links will automatically post a permanent link for an article and, in the case of del.icio.us and ma.gnolia, the title to one of the above services.
