title: PageRef
description: Returns the `pageRef` property of the given menu entry.

The use case for this method is rare.
In almost also scenarios you should use the [`URL`] method instead.
## Explanation
If you specify a `pageRef` property when [defining a menu entry] in your site configuration, Hugo looks for a matching page when rendering the entry.
If a matching page is found:
- The [`URL`] method returns the page's relative permalink
- The [`Page`] method returns the corresponding `Page` object
- The [`HasMenuCurrent`] and [`IsMenuCurrent`] methods on a `Page` object return the expected values
If a matching page is not found:
- The [`URL`] method returns the entry's `url` property if set, else an empty string
- The [`Page`] method returns nil
- The [`HasMenuCurrent`] and [`IsMenuCurrent`] methods on a `Page` object return `false`

Consider this content structure:
```text
content/
├── products.md
└── _index.md
```
And this menu definition:
{{< code-toggle file=hugo >}}
[[menus.main]]
name = 'Products'
pageRef = '/products'
weight = 10
[[menus.main]]
name = 'Services'
pageRef = '/services'
weight = 20
{{< /code-toggle >}}
With this template code:
{{< code file=layouts/partials/menu.html >}}
<ul>
{{ range .Site.Menus.main }}
<li><a href="{{ .URL }}">{{ .Name }}</a></li>
{{ end }}
</ul>
{{< /code >}}
Hugo render this HTML:
```html
<ul>
<li><a href="/products/">Products</a></li>
<li><a href="">Services</a></li>
</ul>
```
In the above note that the `href` attribute of the second `anchor` element is blank because Hugo was unable to find the "services" page.
With this template code:
{{< code file=layouts/partials/menu.html >}}
<ul>
{{ range .Site.Menus.main }}
<li><a href="{{ or .URL .PageRef }}">{{ .Name }}</a></li>
{{ end }}
</ul>
{{< /code >}}
Hugo renders this HTML:
```html
<ul>
<li><a href="/products/">Products</a></li>
<li><a href="/services">Services</a></li>
</ul>
```
In the above note that Hugo populates the `href` attribute of the second `anchor` element with the `pageRef` property as defined in the site configuration because the template code falls back to the `PageRef` method.

The `Ordinal` method returns the zero-based ordinal of the shortcode in relation to its parent. If the parent is the page itself, the ordinal represents the position of this shortcode in the page content.

Hugo increments the ordinal with each shortcode call, regardless of the specific shortcode type. This means that the ordinal value is tracked sequentially across all shortcodes within a given page.

This is a soft deprecation. This method will be removed in a future release, but the removal date has not been established. Although Hugo will not emit a warning if you continue to use this method, you should begin using `SHORTCODE.Store` as soon as possible.

## Methods
###### Set
Sets the value of a given key.
```go-html-template
{{ site.Store.Set "greeting" "Hello" }}
```
###### Get
Gets the value of a given key.
```go-html-template
{{ site.Store.Set "greeting" "Hello" }}
{{ site.Store.Get "greeting" }} → Hello
```
###### Add
Adds a given value to existing value(s) of the given key.
For single values, `Add` accepts values that support Go's `+` operator. If the first `Add` for a key is an array or slice, the following adds will be appended to that list.
```go-html-template
{{ site.Store.Set "greeting" "Hello" }}
{{ site.Store.Add "greeting" "Welcome" }}
{{ site.Store.Get "greeting" }} → HelloWelcome
```
```go-html-template
{{ site.Store.Set "total" 3 }}
{{ site.Store.Add "total" 7 }}
{{ site.Store.Get "total" }} → 10
```
```go-html-template
{{ site.Store.Set "greetings" (slice "Hello") }}
{{ site.Store.Add "greetings" (slice "Welcome" "Cheers") }}
{{ site.Store.Get "greetings" }} → [Hello Welcome Cheers]
```
###### SetInMap
Takes a `key`, `mapKey` and `value` and adds a map of `mapKey` and `value` to the given `key`.
```go-html-template
{{ site.Store.SetInMap "greetings" "english" "Hello" }}
{{ site.Store.SetInMap "greetings" "french" "Bonjour" }}
{{ site.Store.Get "greetings" }} → map[english:Hello french:Bonjour]
```
###### DeleteInMap
Takes a `key` and `mapKey` and removes the map of `mapKey` from the given `key`.
```go-html-template
{{ site.Store.SetInMap "greetings" "english" "Hello" }}
{{ site.Store.SetInMap "greetings" "french" "Bonjour" }}
{{ site.Store.DeleteInMap "greetings" "english" }}
{{ site.Store.Get "greetings" }} → map[french:Bonjour]
```
###### GetSortedMapValues
Returns an array of values from `key` sorted by `mapKey`.
```go-html-template
{{ site.Store.SetInMap "greetings" "english" "Hello" }}
{{ site.Store.SetInMap "greetings" "french" "Bonjour" }}
{{ site.Store.GetSortedMapValues "greetings" }} → [Hello Bonjour]
```
###### Delete
Removes the given key.
```go-html-template
{{ site.Store.Set "greeting" "Hello" }}
{{ site.Store.Delete "greeting" }}
```
## Determinate values
The `Store` method is often used to set scratch pad values within a shortcode, a partial template called by a shortcode, or by a Markdown render hook. In all three cases, the scratch pad values are indeterminate until Hugo renders the page content.
If you need to access a scratch pad value from a parent template, and the parent template has not yet rendered the page content, you can trigger content rendering by assigning the returned value to a [noop] variable:
[noop]: /getting-started/glossary/#noop
```go-html-template
{{ $noop := .Content }}
{{ site.Store.Get "mykey" }}
```
You can also trigger content rendering with the `ContentWithoutSummary`, `FuzzyWordCount`, `Len`, `Plain`, `PlainWords`, `ReadingTime`, `Summary`, `Truncated`, and `WordCount` methods. For example:
```go-html-template
{{ $noop := .WordCount }}
{{ site.Store.Get "mykey" }}
```
