I don’t know why, that mime type doesn’t even exist. Also if I check for
blabla/asdf it returns true. But why? I don’t understand, might someone tell me or is this a bug I’ve just encountered?
I want to check if the browser of the visitor supports
avif image format, I thought it would be best to use above method for.
Hm, yes, getting the same. It happens because in $this->acceptedMimeType() returns
foo/bar will match. The method just checks a matching pattern.
Probably makes more sense to check if
$_SERVER['HTTP_ACCEPT'] explicitly contains the string
image/avif, at least that’s what I did in a plugin.
I have no idea if that is intended behavior of the method.
On a side note, If you use a picture tag, you can provide multiple image sources (avif, webp, jpg) without having to check if the browser supports it.
