I can add an rss widget with this command:
wp widget add rss my-sidebar --title=News --items=5
But when I add a URL parameter, like this:
wp widget add rss my-sidebar --title=News --items=5 --url='https://news.example.com/feed/'
Or like this:
wp widget add rss my-sidebar --title=News --items=5 --url=https://news.example.com/feed/
Or like this:
wp widget add rss my-sidebar --title=News --items=5 --url="https://news.example.com/feed/"
Or any other configuration, it complains Error: Invalid sidebar.
. When I add the sidebar and then try to update the URL parameter, with:
wp widget update rss-6 --url='https://news.example.com/feed/'
Or even:
wp widget update rss-6 --url=https:\/\/news\.example\.com\/feed\/
It says Error: Specified widget isn't present on sidebar.
How can I get it to properly add an RSS widget? I feel like there's something I'm not properly escaping.
--url
parameter and not availabe to sub-commands, as mentioned in this open ticket
