Greetings,
this is a simplified version of the only part of this other thread
https://wordpress.org/support/topic/sharing-uploads-folder-among-different-blogs?replies=3
that is still a very "open issue" to me, that is I fear that even if I test it and it seems to work, I have no idea if it would continue to work after the first updates!
If I create several, independent wordpress blogs, each with its own database, installed side by side under the server root:
$ROOT/blog1
$ROOT/blog2
$ROOT/blog3
but configure ALL of them, in their wp-config.php, to use as uploads folder the SAME place, that is $ROOT/uploads...
will this corrupt the databases, and therefore the blogs? I mean, what will happen if an image is uploaded by user1 of blog1, what will happen to the databases and media library interfaces/caches whatever... of blog2, blog3?
- Will they crash, because they find in there a file that they did not upload?
- Will they NOT see that file, just because it was not updated from blog2, blog3?
- Something else?
I want to do this because while they would be independent blogs, they WOULD share a lot of images. So having one upload folder only, that is only one copy of each image, would save a lot of space AND time (you only upload one image once, then it appears in the media library of all the blogs.
