At the top level of a template that receives a `Page` object in context, these are equivalent:
|
|
|
|
```go-html-template
|
|
{{ .Params.foo }}
|
|
{{ .Page.Params.foo }}
|
|
{{ page.Params.foo }}
|
|
```
|
|
|
|
When a `Page` object is not in context, you can use the global `page` function:
|
|
|
|
```go-html-template
|
|
{{ page.Params.foo }}
|
|
```
|
|
|
|
{{% note %}}
|
|
Do not use the global `page` function in shortcodes, partials called by shortcodes, or cached partials. See [warnings](#warnings) below.
|
|
{{% /note %}}
|
|
|
|
## Explanation
|
|
|
|
Hugo almost always passes a `Page` as the data context into the top level template (e.g., `single.html`). The one exception is the multihost sitemap template. This means that you can access the current page with the `.` in the template.
|
|
|
|
But when you are deeply nested inside of a [content view], [partial], or [render hook], it is not always practical or possible to access the `Page` object.
|
|
|
|
Use the global `page` function to access the `Page` object from anywhere in any template.
|
|
|
|
## Warnings
|
|
|
|
### Be aware of top-level context
|
|
|
|
The global `page` function accesses the `Page` object passed into the top-level template.
|
|
|
|
With this content structure:
|
|
|
|
```text
|
|
content/
|
|
├── posts/
|
|
│ ├── post-1.md
|
|
│ ├── post-2.md
|
|
│ └── post-3.md
|
|
└── _index.md <-- title is "My Home Page"
|
|
```
|
|
|
|
And this code in the home template:
|
|
|
|
```go-html-template
|
|
{{ range site.Sections }}
|
|
{{ range .Pages }}
|
|
{{ page.Title }}
|
|
{{ end }}
|
|
{{ end }}
|
|
```
|
|
|
|
The rendered output will be:
|
|
|
|
```text
|
|
My Home Page
|
|
My Home Page
|
|
My Home Page
|
|
```
|
|
|
|
In the example above, the global `page` function accesses the `Page` object passed into the home template; it does not access the `Page` object of the iterated pages.
|
|
|
|
### Be aware of caching
|
|
|
|
Do not use the global `page` function in:
|
|
|
|
- Shortcodes
|
|
- Partials called by shortcodes
|
|
- Partials cached by the [`partialCached`] function
|
|
|
|
Hugo caches rendered shortcodes. If you use the global `page` function within a shortcode, and the page content is rendered in two or more templates, the cached shortcode may be incorrect.
|
|
|
|
Consider this section template:
|
|
|
|
```go-html-template
|
|
{{ range .Pages }}
|
|
<h2><a href="{{ .RelPermalink }}">{{ .LinkTitle }}</a></h2>
|
|
{{ .Summary }}
|
|
{{ end }}
|
|
```
|
|
|
|
When you call the [`Summary`] method, Hugo renders the page content including shortcodes. In this case, within a shortcode, the global `page` function accesses the `Page` object of the section page, not the content page.
|
|
|
|
If Hugo renders the section page before a content page, the cached rendered shortcode will be incorrect. You cannot control the rendering sequence due to concurrency.
