InSection
Syntax
PAGE.InSection SECTION
Returns
bool
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 with 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.
{{ with .Site.GetPage "/auctions" }}
{{ $.InSection . }} → true
{{ end }}
