Section Variables and Methods
Also see Sections.
{{< readfile file="/content/en/readfiles/sectionvars.md" markdown="true" >}}
The .Pages
Variable
.Pages
is an alias to .Data.Pages
. It is conventional to use the
aliased form .Pages
.
.Pages
compared to .Site.Pages
{{< readfile file="/content/en/readfiles/pages-vs-site-pages.md" markdown="true" >}}
Page-level Params
Any other value defined in the front matter in a content file, including taxonomies, will be made available as part of the .Params
variable.
---
title: My First Post
date: 2017-02-20T15:26:23-06:00
categories: [one]
tags: [two,three,four]
With the above front matter, the tags
and categories
taxonomies are accessible via the following:
.Params.tags
.Params.categories
{{% note "Casing of Params" %}}
Page-level .Params
are only accessible in lowercase.
{{% /note %}}
The .Params
variable is particularly useful for the introduction of user-defined front matter fields in content files. For example, a Hugo website on book reviews could have the following front matter in /content/review/book01.md
:
---
...
affiliatelink: "http://www.my-book-link.here"
recommendedby: "My Mother"
...
---
These fields would then be accessible to the /themes/yourtheme/layouts/review/single.html
template through .Params.affiliatelink
and .Params.recommendedby
, respectively.
Two common situations where this type of front matter field could be introduced is as a value of a certain attribute like href=""
or by itself to be displayed as text to the website's visitors.
{{< code file="/themes/yourtheme/layouts/review/single.html" >}}
Buy this book
It was recommended by {{ .Params.recommendedby }}.
{{< /code >}}This template would render as follows, assuming you've set uglyURLs
to false
in your site config
:
{{< output file="yourbaseurl/review/book01/index.html" >}}
Buy this book
It was recommended by my Mother.
{{< /output >}}{{% note %}}
See Archetypes for consistency of Params
across pieces of content.
{{% /note %}}
The .Param
Method
In Hugo, you can declare params in individual pages and globally for your entire website. A common use case is to have a general value for the site param and a more specific value for some of the pages (i.e., a header image):
{{ $.Param "header_image" }}
The .Param
method provides a way to resolve a single value according to it's definition in a page parameter (i.e. in the content's front matter) or a site parameter (i.e., in your config
).
Access Nested Fields in Front Matter
When front matter contains nested fields like the following:
---
author:
given_name: John
family_name: Feminella
display_name: John Feminella
---
.Param
can access these fields by concatenating the field names together with a dot:
{{ $.Param "author.display_name" }}
If your front matter contains a top-level key that is ambiguous with a nested key, as in the following case:
---
favorites.flavor: vanilla
favorites:
flavor: chocolate
---
The top-level key will be preferred. Therefore, the following method, when applied to the previous example, will print vanilla
and not chocolate
:
{{ $.Param "favorites.flavor" }}
=> vanilla
