The problem is that different persons usually want to display different movie details, mostly in a different style. That’s why I’ve invested a lot of time into making the PHP functions as flexible as possible so that anyone with a bit HTML and PHP knowledge can build their own snippet.
The only thing I could imagine implementing would be an additional array into the PHP function that assings the Rich Snippet tag to the corresponding movie detail. But that, too, requires a bit of custom code to match the individual layout.
I’m always up for new functions, and Rich Snippets seem to be a good idea. I’m just a bit unsure about how to implement it. Displaying them as a template via a shortcode will be the worst option in my eyes since there’s very little ways for users to adjust the output to their needs. Do you have any more ideas?
