Nobunobu’s Xoops version of the WordPress Module includes a file called wp-rss.php. This file generates RSS for the blog in question. Specifying cat=n, where n is a category number, extracts only the posts in that category, but it has the following problems:
(1) The channel title becomes the blog name rather than the category name.
(2) The link destination becomes the whole site rather than the page filtered by category.
So I created a modified version that generates RSS for each category.
http://www.sakimura.org/modules/wordpress/wp-rss-cat.php.txt is that file.
On another topic, it seems that the WordPress module’s ping destinations can be changed by editing wp-config.php, but I was not quite sure how to do it. I posted a question on Nobunobu’s BBS. A reply came back immediately.
I apologize for the confusion in some of the documentation, but settings are now made not in wp-config.php, but in themes/xxxxx/wp-config-custom.php.
For details, please refer to the discussion of PING on this BBS.
I see…
