So around a week ago, every image on my site broke.
This plugin should allow you to hardcode your upload directory in the event that the UPLOADS constant doesn't work. This is a quick, and incredibly dirty fix. You can find it on github:
WordPress, by default, uses
/wp-content/uploads for uploads, usually images. You can customize this and other directories using PHP constants, usually set in wp-config.php. WordPress briefly documents these constants here.
I use the UPLOADS constant to put my uploads in
/media instead because I like it more. Until about a week ago.
I'm not sure if it was a wordpress update, a plugin, or a change with my hosting behind the scenes. I was working on developing a plugin at the time, I suspected that I'd just broken something. I tried disabling 99% of my plugins, with no dice. I triple checked the database. Etcetera. For one reason or another, wordpress started ignoring the UPLOADS constant.
Fix Uploads Dir uses the WordPress filter
upload_dir to manually ater the url WordPress fetches for attachments. It's messy and far from perfect, but functional for me. I've also created a basic settings page (an act that took twice the code of the original plugin) to allow you to configure it without just hardcoding.
I guiltily hope that this has ever been an issue for someone else, so that this proves useful. I know there were approximately 0 helpful results when I started looking into this. And it'd be neat to be that helpful person once.
