WSN has had an "add from web search" option for a while which can be very useful for filling up a directory with websites appropriate to a category. For a business directory, however, it would make things a lot easier if WSN could determine the address and phone number of the business which each search result references.

With the cooperation and forethought of the website owner, the geo.position and icbm meta tags can help. These meta tags allow a web page to specify its' latitude and longitude. As of today's 9.2.31 Beta 2 release, WSN now detects this and also does a reverse geocode to get the address.

Unfortunately, very few websites are currently using geodata in their meta tags. To get a few more addresses, I've used some regular expression page parsing to look for a couple of common USA address formats in pages. Also added USA phone number detection. Detection remains very spotty due to the infinite variety of ways that web pages represent addresses, but it's a start.

Thanks to clipboard.js, I've just added cross-platform copy-to-clipboard functionality to WSN's template editor. This replaces an archaic javascript which had only been able to select the contents without copying in most browsers. Are there any other places where cut/copy to clipboard functionality would be useful?

Another change today was a formatting change to the RSS Feed template to achieve full Atom feed support by default. WSN's rssfeed.php now outputs a feed which is valid both as RSS 2.0 and Atom.

9.2.30 also brings some fixes. These includes a fix to processing template conditionals in non-mime email headers and footers (notably the default email footer with the unsubscribe link now only shows to members, as it should). Also fixed watermarking for images and added an easier AJAXy remove watermark option.

Did a lot of work on RSS feeds today. A comments url is now included in listing feeds whenever the comments switch is on and the combine details and comments switch is off. Article and topic feeds from WSN Knowledge Base and WSN Forum now include content:encoded fields to syndicate the complete article text or topic message. Any listing that has a physical address now includes the georss point field with the coordinates. On the other end, I fixed a WSN Knowledge Base bug which was affecting display of article text from feed submissions.

In the process of this work, I stumbled across the website fulltextrssfeed.com. That site will take RSS feed which only contain introductory stubs about articles and will pull in the complete article text to create a much more useful feed. Of course, you can't just do that with any feed without running into copyright issues -- but it can make the process of syndicating content between your own websites a whole lot easier.

I've demoed these changes in the WSN Knowledge Base user demo by submitting this blog as a feed: http://demo.wsnforum.com/wsnkb/blog-feed/

Let me know if you have any creative ideas for making the feed-posting system even more powerful.

For many years, WSN has been using an open source flash script called OSFLV for embedding uploaded videos. This required activating the "convert videos to flv" switch and ensuring that ffmpeg was installed on your web server, which wasn't always possible in shared hosting environments and could be a pain on unmanaged dedicated servers. Also, more importantly, it meant your mobile users couldn't watch the videos because mobile devices don't usually support Flash.

Recently I found that OSFLV was no longer working correctly -- the osplayer.swf player wasn't showing up. I looked for documentation and discovered that the OSFLV script is no longer developed and the online materials for it have been taken down. Since it's dangerous to continue relying on a component that's abandoned (it could develop security holes), I set out to find a replacement video player component.

In the end, I settled on Flow Player. It has good documentation, is easy to integrate, and has the popularity and longevity to indicate that it'll stick around for years to come. It's integrated now in WSN 9.2.27.

A bonus from this change is that Flow Player isn't limited to flv videos -- any type of video can now be played. Under the hood, this uses the HTML 5 <video> tag. The upshot is that you no longer need ffmpeg (or youtube) in order to show uploaded videos with a listing. You also no longer need flash, which means if you upload a .mov, .mp4, .m4v or .avi file it can play on an ipad, iphone or other mobile devices that don't have Flash.

FFmpeg is still useful for autogenerating thumbnail images from videos, so the autoconversion switch will remain.

Sorry for the downtime on some parts of the websites this week. After selling my most server-intensive site I've been downsizing from a dedicated server to shared hosting, and the process has proved more complicated than anticipated. Everything except the demos is back up now, and I'll get to the demos shortly.

In the process I found and fixed a moving-related bug with integrated sites. The uploadpath value in the database doesn't change automatically when the config.php version of that value changes, and this results in integrated scripts failing to find the themes. Run upgrade.php to fix that.

Just as a tip for anyone else moving a website, make sure you don't copy the cache directory -- those thousands of small files take forever and aren't necessary.
