Here's a little plugin that interfaces with the Feedsplitter service to enable javascript driven access to RSS feeds from your template. It takes the following parameters, all optional except for "feed":
feed - url to the rss feed you wish to display
maxitems - number of items to display
target - name of target window (use "_blank" for new windows)
stylesheet - set to true to use Feedsplitter's stylesheet
recache - set to true to recache the feed at Feedster
noscript - message to display in place of feed if javascript is not available
eg:
Code: | {feedsplitter feed="http://www.phpinsider.com/smarty-forum/rdf.php" target="_blank" stylesheet=true} |
Enjoy!

ps. Just to fend off any questions, I realize that the smarty_function_feedsplitter_verify() function can be folded directly into the plugin function. It is actually stripped out (and down) from a class I am working on that is meant to be a helper for plugin writers by abstracting repeated patterns like checking plugin inputs and instead only requiring a "simple" definition of the requirements for the plugin. If it gets to the point where I am happy with it, I will post the results of that experiment. In the meantime, just include both of the above functions in the plugin file (function.feedsplitter.php) and you can ignore the fact that it contains two functions. |
