I'm trying to create a custom form which takes an image (offsite) and attaches it to the post so I can use it as a thumbnail in the loop. I've been looking at media_handle_upload but that appears to only be working for content that's locally uploaded.
Ideas?
Thanks, Dennis
When you link to an external image, WordPress will reference the external URL. media_handle_upload is meant to handle uploaded images that are now living on your server. So unless you're telling the server to download the image from the external source and save it on your server, media_handle_upload won't apply.
It sounds like you're building your own custom importer. I recommend you take a deeper look at the process. A typical upload:
media_handle_upload, and stores it on the serverIf you're referencing an offsite image and attaching it to the post, WordPress won't do steps 2 and 3. You'll need to add your own scripts to grab the remote image and store a copy locally.
media_handle_upload on uploaded media. So if you want to use the offsite image in the loop as a thumbnail, you need to make your plugin fetch the image and store it locally on the server following the same path a file would take if the user were to upload it directly.
