Hello all! I am trying to tackle what I think is a two step process.
1) Use PHP to upload and add a new piece of media
2) Use PHP to set the featured image for a known post ID to the media ID I just uploaded.
I think I found a function to cover the second part but I am struggling to come up with a solution that will allow me to programmatically upload media to the media library. Any tips or advice would be appreciated.
