I want to sort my blog posts based on publish date, so that I can show .Date as describing the date that I started writing the post, and .PublishDate as the date that the post actually exists publically.
Right now, a regular {{ range .RegularPages }} sorts based on .Date, not .PublishDate.
Have a look at this topic, as it describes the general methods that can be used on single page templates, to change the sorting order of pages called with .PrevInSection, .NextInSection etc.
Thanks a lot! I used a modified form of his code snippet:
<section class="post-navigation">
{{/*We get the posts within the section and then sort by publish date in descending order.*/}}
{{ $pages := (sort (where site.RegularPages "Section" .Section) ".PublishDate" "desc") }}
<div>{{ with $pages.Prev . }}{{ if .PublishDate }}<a href="{{.Permalink}}">
{{ with .Title }}{{ . }}{{ else }}{{ .Summary | truncate 70 }}{{ end }}</a> {{ end }}{{ end }}</div>
<div>{{ with $pages.Next . }}{{ if .PublishDate }}<a
href="{{.Permalink}}">{{ with .Title }}{{ . }}{{ else }}{{ .Summary | truncate 70 }}{{ end }} </a> {{ end }}{{ end }}</div>
{{ end }}
</section>
