Given a Vimeo ID, I can retrieve a thumbnail from the video via Vimeo Simple API. Rather than call the API every time my page loads I want to set the image as the post thumbnail using the
save_post hook (similar to this question).
My problem is that I am not familiar with URL calls in php. I would like to know:
the benefits/drawbacks of using a method like curl compared to
WP_Http. Is one "better" than the other?
the order in which I should call functions to successfully set the post thumbnail.
Any help would be greatly appreciated.
