Hello,
I have written some php code to produce RSS feeds when new data is added to my database. I have a website (customised) with WordPress that is used to display this data which also works as a blog with its own RSS feed (rss2, atom) etc.
I would like to merge my other custom rss feeds into the WordPress RSS so new data is pushed through a combined RSS feed, ideally without hacking the core WordPress code.
I cannot see any hooks in the feed-xxx.php files in WordPress to do this, so was wondering if anyone knew a way this could be done?
Essentially i want to add content to the RSS feed (as separate items) without them appearing as posts on the actual blog - bonus content if you like, to subscribers.
The codex and search of wordpress.org doesn't return very much when searching for RSS and almost all of google returns RSS feed subscription button widgets or taking other site's feeds and publishing them as posts.
