With this site configuration:
|
|
|
|
{{< code-toggle file=hugo >}}
|
|
[params]
|
|
subtitle = 'The Best Widgets on Earth'
|
|
copyright-year = '2023'
|
|
[params.author]
|
|
email = 'jsmith@example.org'
|
|
name = 'John Smith'
|
|
[params.layouts]
|
|
rfc_1123 = 'Mon, 02 Jan 2006 15:04:05 MST'
|
|
rfc_3339 = '2006-01-02T15:04:05-07:00'
|
|
{{< /code-toggle >}}
|
|
|
|
Access the custom parameters by [chaining] the [identifiers]:
|
|
|
|
```go-html-template
|
|
{{ .Site.Params.subtitle }} → The Best Widgets on Earth
|
|
{{ .Site.Params.author.name }} → John Smith
|
|
|
|
{{ $layout := .Site.Params.layouts.rfc_1123 }}
|
|
{{ .Site.LastChange.Format $layout }} → Tue, 17 Oct 2023 13:21:02 PDT
|
|
```
|
|
|
|
In the template example above, each of the keys is a valid identifier. For example, none of the keys contains a hyphen. To access a key that is not a valid identifier, use the [`index`] function:
|
|
|
|
```go-html-template
|
|
{{ index .Site.Params "copyright-year" }} → 2023
|
|
```
|
