InSection
Syntax
Returns
The InSection
method on a Page
object reports whether the given page is in the given section. Note that the method returns true
when comparing a page to a sibling.

A section is a top-level content directory or any content directory containing an _index.md
file.
With this content structure:
content/
├── auctions/
│ ├── 2023-11/
│ │ ├── _index.md
│ │ ├── auction-1.md
│ │ └── auction-2.md
│ ├── 2023-12/
│ │ ├── _index.md
│ │ ├── auction-3.md
│ │ └── auction-4.md
│ ├── _index.md
│ ├── bidding.md
│ └── payment.md
└── _index.md
When rendering the “auction-1” page:
{{ with .Site.GetPage "/" }}
{{ $.InSection . }} → false
{{ end }}
{{ with .Site.GetPage "/auctions" }}
{{ $.InSection . }} → false
{{ end }}
{{ with .Site.GetPage "/auctions/2023-11" }}
{{ $.InSection . }} → true
{{ end }}
{{ with .Site.GetPage "/auctions/2023-11/auction-2" }}
{{ $.InSection . }} → true
{{ end }}
In the examples above we are coding defensively using the
with
statement, returning nothing if the page does not exist. By adding an
else
clause we can do some error reporting:
{{ $path := "/auctions/2023-11" }}
{{ with .Site.GetPage $path }}
{{ $.InSection . }} → true
{{ else }}
{{ errorf "Unable to find the section with path %s" $path }}
{{ end }}
Understanding context
Inside of the with
block, the
context (the dot) is the section Page
object, not the Page
object passed into the template. If we were to use this syntax:
{{ with .Site.GetPage "/auctions" }}
{{ .InSection . }} → true
{{ end }}
The result would be wrong when rendering the “auction-1” page because we are comparing the section page to itself.
Use the $
to get the context passed into the template.
{{ with .Site.GetPage "/auctions" }}
{{ $.InSection . }} → true
{{ end }}
Gaining a thorough understanding of context is critical for anyone writing template code.
