# Do not remove front matter.

Hugo determines the _next_ and _previous_ page by sorting the current section's regular pages according to this sorting hierarchy:
|
||
|
|
||
|
Field|Precedence|Sort direction
|
||
|
:--|:--|:--
|
||
|
[`weight`]|1|descending
|
||
|
[`date`]|2|descending
|
||
|
[`linkTitle`]|3|descending
|
||
|
[`path`]|4|descending
|
||
|
|
||
|
[`date`]: /methods/page/date/
|
||
|
[`weight`]: /methods/page/weight/
|
||
|
[`linkTitle`]: /methods/page/linktitle/
|
||
|
[`path`]: /methods/page/path/
|
||
|
|
||
|
The sorted page collection used to determine the _next_ and _previous_ page is independent of other page collections, which may lead to unexpected behavior.
|
||
|
|
||
|
For example, with this content structure:
|
||
|
|
||
|
```text
|
||
|
content/
|
||
|
├── pages/
|
||
|
│ ├── _index.md
|
||
|
│ ├── page-1.md <-- front matter: weight = 10
|
||
|
│ ├── page-2.md <-- front matter: weight = 20
|
||
|
│ └── page-3.md <-- front matter: weight = 30
|
||
|
└── _index.md
|
||
|
```
|
||
|
|
||
|
And these templates:
|
||
|
|
||
|
{{< code file=layouts/_default/list.html >}}
|
||
|
{{ range .Pages.ByWeight }}
|
||
|
<h2><a href="{{ .RelPermalink }}">{{ .LinkTitle }}</a></h2>
|
||
|
{{ end }}
|
||
|
{{< /code >}}
|
||
|
|
||
|
{{< code file=layouts/_default/single.html >}}
|
||
|
{{ with .PrevInSection }}
|
||
|
<a href="{{ .RelPermalink }}">Previous</a>
|
||
|
{{ end }}
|
||
|
|
||
|
{{ with .NextInSection }}
|
||
|
<a href="{{ .RelPermalink }}">Next</a>
|
||
|
{{ end }}
|
||
|
{{< /code >}}
|
||
|
|
||
|
When you visit page-2:
|
||
|
|
||
|
- The `PrevInSection` method points to page-3
|
||
|
- The `NextInSection` method points to page-1
|
||
|
|
||
|
To reverse the meaning of _next_ and _previous_ you can change the sort direction in your [site configuration], or use the [`Next`] and [`Prev`] methods on a `Pages` object for more flexibility.
|
||
|
|
||
|
[site configuration]: getting-started/configuration/#configure-page
|
||
|
[`Next`]: /methods/pages/prev
|
||
|
[`Prev`]: /methods/pages/prev
|
||
|
|
||
|
## Example
|
||
|
|
||
|
Code defensively by checking for page existence:
|
||
|
|
||
|
```go-html-template
|
||
|
{{ with .PrevInSection }}
|
||
|
<a href="{{ .RelPermalink }}">Previous</a>
|
||
|
{{ end }}
|
||
|
|
||
|
{{ with .NextInSection }}
|
||
|
<a href="{{ .RelPermalink }}">Next</a>
|
||
|
{{ end }}
|
||
|
```
|
||
|
|
||
|
## Alternative
|
||
|
|
||
|
Use the [`Next`] and [`Prev`] methods on a `Pages` object for more flexibility.
