    Can someone explain how a button placed in a post can trigger the content of a widget to be updated – how to request the widget content to refresh? I’ve read the Codex but it’s still unclear. Thanks.

    [FYI, I am replacing a short code and an ID argument with a button. When the button is clicked, the ID argument from the shortcode will display in the widget’s content.]

    There’s a number of ways, one common method is the button click event triggers a javascript or jquery function. This begins an AJAX or similar transaction where the function requests data from your server. If the data is successfully received, it is placed into a DOM container using the innerHTML method or equivalent.

    The only thing the codex is really useful for is how to enqueue javascript and a brief AJAX ovewrview. Turn to the web in general for AJAX techniques, it is not specific to WordPress.
