When I attempted to use `func/GetFeaturedImage.html`, it did not find my resource, `images/foo-cover.webp`. Updating the match syntax to the pattern expressed here, provided expected behavior: Per: https://gohugo.io/content-management/page-resources/#pattern-matching > .Resources.Match "*sunset.jpg" 🚫 and... > .Resources.Match "*" 🚫 Are not expected to work > .Resources.Match "**/sunset.jpg" ✅ which follows this change, does.

GetFeaturedImage
|
|
|
|
This partial gets the url for featured image for a given page.
|
|
|
|
If a featured_image was set in the page's front matter, then that will be used.
|
|
|
|
If not set, this will search page resources to find an image that contains the word
|
|
"cover", and if found, returns the path to that resource.
|
|
|
|
If no featured_image was set, and there's no "cover" image in page resources, then
|
|
this partial returns an empty string (which evaluates to false).
|
|
|
|
@return Permalink to featured image, or an empty string if not found.
