I’d like to create this list of PDFs – under the 2025 bulletins heading – by using DisplayPosts to loop through the corresponding attachments (from the Media Library).<\/p>\n\n\n\n

The issue is that the typically two or three links per Sunday are offset by a blank line before and after.<\/p>\n\n\n\n

I could accomplish that either through nesting loops – <\/p>\n\n\n\n

for date = first sunday through last sunday
    for service in date.services
         <print text and link for service.bulletin>
    end service
end date
<\/code><\/pre>\n\n\n\n
or by <\/p>\n\n\n\n
previousSundayDate = \"xxx\"
for service = first service of the year through last service of the year
   thisSundayDate = service.SundayDate
   if previousSundayDate <> thisSundayDate
      <print offset>
   <print text and link for service.bulletin>
   previousSundaydate = thisSundayDate
end service
   <\/code><\/pre>\n\n\n\n
How do I accomplish either with DisplayPosts? Part of the answer may lie in https:\/\/displayposts.com\/2019\/01\/04\/enable-display-posts-within-post-listing\/<\/a><\/p>\n\n\n\n
but the way I read that I would have to create a bunch of posts, one for each Sunday, using DisplayPosts to loop through the Bulletins for that Sunday, and then loop through the bunch of posts. Seems cumbersome, since I don’t need the individual posts, one for each Sunday.<\/p>\n","protected":false},"template":"","class_list":["post-18482903","topic","type-topic","status-publish","hentry","topic-tag-nested-loop"],"jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/topic\/18482903","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/topic"}],"about":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/topic\/18482903\/revisions"}],"wp:attachment":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/media?parent=18482903"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
