[pLog-svn] r2030 - in plog/branches/plog-1.0.1: class/dao templates/rss

[Oscar Renalias]

been meaning to do this for a while but it never seemed to be the
right time... But it's finally here for those into podcastig or
vlogging :-)

I've modified the resource chooser (the pop-up window one gets when
clicking the "add resource" link in the new post and edit post pages)
so that it adds an extra "id" attribute to each one of the links that
point to resources which contains the internal resource identifier of
the file. Otherwise I didn't see an easy way to keep track of the
links to files that had been added from the resource centre... and
nobody *usually* uses the "id" attribute of links nayway.

The new method Article::getArticleResources() basically extracts all
those id attributes via a regexp and then tries to load the
GalleryResource object with the given identifier. If it can be found,
it adds it to an array and if not it ignores it.

The result is an array of GalleryResource objects that can be handled
like any other object. We can query the description, size, link, etc.

The only downside is that this does not affect old posts, or links
which are manually added unless the "id" attribute is added
afterwards. As I said, I couldn't find an easy way to identify which
links point to local resources and which ones don't, so this seemed
the best alternative. Let me know if you can think of something better
:)
