Wiebe uses his author Atom feed to generate a list of his blog posts here on his own website. WordPress feeds only display the latest 10 entries. He has written 16 so far. What he needs is a feed with all his entries.
First, I tried if pagination works for feeds. Appending “/page/2” (as is used an non-feed lists) to a feed URL gives a 404 so I was kind of stuck there. Four days ago, after Googling for some time, unable to find a solution anywhere, I asked on the forum. Still no answer today so I tried to find out which parameters WordPress accepts in the QUERY_STRING. The WordPress Codex does explain how queries are handled but not which parameters are accepted.
Digging into wp-includes/query.php, with much trial and error, I found out that I can append
?paged=2 to the URL to get the next page. At least I got that sorted then. There are a number of much more promising parameters supported by get_posts(), but these don’t seem to be parsed by parse_query(). Next time, I’d like to find out how how to use two of these: nopaging and posts_per_page.
Wiebe could complete his list by merging together all the pages of the feed, but I’d much prefer to find a relatively painless method to produce a feed with an unlimited number of posts.
