Many of these will be defined in the front matter, derived from file location, or extracted from the content itself. {{% note "`.Scratch`" %}} See [`.Scratch`](/functions/scratch/) for page-scoped, writable variables. {{% /note %}} ## Page Variables .AlternativeOutputFormats : contains all alternative formats for a given page; this variable is especially useful `link rel` list in your site's `
`. (See [Output Formats](/templates/output-formats/).) .Content : the content itself, defined below the front matter. .Data : the data specific to this type of page. .Date : the date associated with the page; `.Date` pulls from the `date` field in a content's front matter. See also `.ExpiryDate`, `.PublishDate`, and `.Lastmod`. .Description : the description for the page. .Dir : the path of the folder containing this content file. The path is relative to the `content` folder. .Draft : a boolean, `true` if the content is marked as a draft in the front matter. .ExpiryDate : the date on which the content is scheduled to expire; `.ExpiryDate` pulls from the `expirydate` field in a content's front matter. See also `.PublishDate`, `.Date`, and `.Lastmod`. .File : filesystem-related data for this content file. See also [File Variables][]. .FuzzyWordCount : the approximate number of words in the content. .Hugo : see [Hugo Variables](/variables/hugo/). .IsHome : `true` in the context of the [homepage](/templates/homepage/). .IsNode : always `false` for regular content pages. .IsPage : always `true` for regular content pages. .IsTranslated : `true` if there are translations to display. .Keywords : the meta keywords for the content. .Kind : the page's *kind*. Possible return values are `page`, `home`, `section`, `taxonomy`, or `taxonomyTerm`. Note that there are also `RSS`, `sitemap`, `robotsTXT`, and `404` kinds, but these are only available during the rendering of each of these respective page's kind and therefore *not* available in any of the `Pages` collections. .Lang : language taken from the language extension notation. .Language : a language object that points to the language's definition in the site `config`. .Lastmod : the date the content was last modified. `.Lastmod` pulls from the `lastmod` field in a content's front matter. - If `lastmod` is not set, and `.GitInfo` feature is disabled, the front matter `date` field will be used. - If `lastmod` is not set, and `.GitInfo` feature is enabled, `.GitInfo.AuthorDate` will be used instead. See also `.ExpiryDate`, `.Date`, `.PublishDate`, and [`.GitInfo`][gitinfo]. .LinkTitle : access when creating links to the content. If set, Hugo will use the `linktitle` from the front matter before `title`. .Next : pointer to the following content (based on the `publishdate` field in front matter). .NextInSection : pointer to the following content within the same section (based on `publishdate` field in front matter). .OutputFormats : contains all formats, including the current format, for a given page. Can be combined the with [`.Get` function](/functions/get/) to grab a specific format. (See [Output Formats](/templates/output-formats/).) .Pages : a collection of associated pages. This value will be `nil` for regular content pages. `.Pages` is an alias for `.Data.Pages`. .Permalink : the Permanent link for this page; see [Permalinks](/content-management/urls/) .Plain : the Page content stripped of HTML tags and presented as a string. .PlainWords : the Page content stripped of HTML as a `[]string` using Go's [`strings.Fields`](https://golang.org/pkg/strings/#Fields) to split `.Plain` into a slice. .Prev : Pointer to the previous content (based on `publishdate` in front matter). .PrevInSection : Pointer to the previous content within the same section (based on `publishdate` in front matter). For example, `{{if .PrevInSection}}{{.PrevInSection.Permalink}}{{end}}`. .PublishDate : the date on which the content was or will be published; `.Publishdate` pulls from the `publishdate` field in a content's front matter. See also `.ExpiryDate`, `.Date`, and `.Lastmod`. .RSSLink : link to the taxonomies' RSS link. .RawContent : raw markdown content without the front matter. Useful with [remarkjs.com]( http://remarkjs.com) .ReadingTime : the estimated time, in minutes, it takes to read the content. .Ref : returns the permalink for a given reference (e.g., `.Ref "sample.md"`). `.Ref` does *not* handle in-page fragments correctly. See [Cross References](/content-management/cross-references/). .RelPermalink : the relative permanent link for this page. .RelRef : returns the relative permalink for a given reference (e.g., `RelRef "sample.md"`). `.RelRef` does *not* handle in-page fragments correctly. See [Cross References](/content-management/cross-references/). .Site : see [Site Variables](/variables/site/). .Summary : a generated summary of the content for easily showing a snippet in a summary view. The breakpoint can be set manually by inserting<!--more-->
at the appropriate place in the content page. See [Content Summaries](/content-management/summaries/) for more details.
.TableOfContents
: the rendered [table of contents](/content-management/toc/) for the page.
.Title
: the title for this page.
.Translations
: a list of translated versions of the current page. See [Multilingual Mode](/content-management/multilingual/) for more information.
.Truncated
: a boolean, `true` if the `.Summary` is truncated. Useful for showing a "Read more..." link only when necessary. See [Summaries](/content-management/summaries/) for more information.
.Type
: the [content type](/content-management/types/) of the content (e.g., `post`).
.URL
: the URL for the page relative to the web root. Note that a `url` set directly in front matter overrides the default relative URL for the rendered page.
.UniqueID
: the MD5-checksum of the content file's path.
.Weight
: assigned weight (in the front matter) to this content, used in sorting.
.WordCount
: the number of words in the content.
## Section Variables and Methods

{{< readfile file="/content/readfiles/sectionvars.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" >}}
It was recommended by {{ .Params.recommendedby }}.
{{< /code >}} This template would render as follows, assuming you've set [`uglyURLs`](/content-management/urls/) to `false` in your [site `config`](/getting-started/configuration/): {{< output file="yourbaseurl/review/book01/index.html" >}}It was recommended by my Mother.
{{< /output >}} {{% note %}} See [Archetypes](/content-management/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 ``` [gitinfo]: /variables/git/ [File Variables]: /variables/files/
