With this front matter:
|
|
|
|
{{< code-toggle file=content/news/annual-conference.md >}}
|
|
title = 'Annual conference'
|
|
date = 2023-10-17T15:11:37-07:00
|
|
[params]
|
|
display_related = true
|
|
[params.author]
|
|
email = 'jsmith@example.org'
|
|
name = 'John Smith'
|
|
{{< /code-toggle >}}
|
|
|
|
The `title` and `date` fields are standard parameters---the other fields are user-defined.
|
|
|
|
Access the custom parameters by [chaining] the [identifiers]:
|
|
|
|
```go-html-template
|
|
{{ .Params.display_related }} → true
|
|
{{ .Params.author.name }} → John Smith
|
|
```
|
|
|
|
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 .Params "key-with-hyphens" }} → 2023
|
|
```
