In Hugo, you can declare [site-wide params][sitevars] (i.e. in your [configuration][]), as well as params for [individual pages][pagevars].
|
|
|
|
A common use case is to have a general value for the site and a more specific value for some of the pages (e.g., an image).
|
|
|
|
You can use the `.Param` method to call these values into your template. The following will first look for an `image` param in a specific content's [front matter][]. If not found, Hugo will look for an `image` param in your site's configuration:
|
|
|
|
```
|
|
$.Param "image"
|
|
```
|
|
|
|
{{% note %}}
|
|
The `Param` method may not consider empty strings in a content's front matter as "not found." If you are setting preconfigured front matter fields to empty strings using Hugo's archetypes, it may be best to use the [`default` function](/functions/default/) instead of `Param`. See the [related issue on GitHub](https://github.com/gohugoio/hugo/issues/3366).
