## PageInner details
|
|
|
|
{{< new-in 0.125.0 >}}
|
|
|
|
The primary use case for `PageInner` is to resolve links and [page resources] relative to an included `Page`. For example, create an "include" shortcode to compose a page from multiple content files, while preserving a global context for footnotes and the table of contents:
|
|
|
|
{{< code file=layouts/shortcodes/include.html >}}
|
|
{{ with site.GetPage (.Get 0) }}
|
|
{{ .RenderShortcodes }}
|
|
{{ end }}
|
|
{{< /code >}}
|
|
|
|
Then call the shortcode in your Markdown:
|
|
|
|
{{< code file=content/posts/p1.md >}}
|
|
{{%/* include "/posts/p2" */%}}
|
|
{{< /code >}}
|
|
|
|
Any render hook triggered while rendering `/posts/p2` will get:
|
|
|
|
- `/posts/p1` when calling `Page`
|
|
- `/posts/p2` when calling `PageInner`
|
|
|
|
`PageInner` falls back to the value of `Page` if not relevant, and always returns a value.
|
|
|
|
{{% note %}}
|
|
The `PageInner` method is only relevant for shortcodes that invoke the [`RenderShortcodes`] method, and you must call the shortcode using the `{{%/*..*/%}}` notation.

As a practical example, Hugo's embedded link and image render hooks use the `PageInner` method to resolve markdown link and image destinations. See the source code for each:
|
|
|
|
- [Embedded link render hook]({{% eturl render-link %}})
|
|
- [Embedded image render hook]({{% eturl render-image %}})
