This RSS import feature was the kicker for me to install Pligg for testing, and I've played somewhat with it over the past couple of days. A few things I've noticed:
1. I agree with the previous poster that it would be great to have some pre-set field configs available. I imported 12 feeds, and ended up doing the same <title> -> link_title, <link> -> link_url, <description> -> link_content config for each one of them straight into the database because the UI is currently too slow for that.
2. Any site which syndicates their feed through FeedBurner is shown in the postings as "www.feedburner.com" with FeedBurner's thumbnail instead of their own. This makes the thumbnail feature (which is a VERY nice touch) practically useless for these sites (which are plenty..). I take it this is because the site's address is taken from each post's link? For the case of RSS feeds, and in particular for FeedBurner's feeds, the RSS's <channel><link> field has the right address. Unfortunately that seems to mean a new DB field would be required - otherwise I might have tried to hack that together already.
3. I noticed a bug in the "paginator" compontent (html1.php/do_pages) that caused the pages beyond the first one in queued news to break. My fix was pretty trivial, replacing "?page=" with "&page=" for all occurrencies within that function. What's the preferred way to submit patches (sorry, I'm new here)?
4. Some feeds (such as Read/WriteWeb at
http://feeds.feedburner.com/readwriteweb) contain a lot of HTML markup, including links to pictures etc. Importing such a feed to Pligg breaks the posts pretty badly when the HTML is stripped. Hard to describe, easy to experience; just try importing this feed. Personally, I'd prefer that the feed wasn't stripped at all, but I can see why that might be desirable.
Good job on the software, by the way. Even with these items, I'm very happy with the results I've seen, especially given how little time I've needed to spend getting this far. Thanks!
