Change Destination Of Custom File Upload Field Type

Hi Anh,

Could this be used to restrict users to accessing their own upload directory/files in the Media Library, an often requested feature in many forums.

The concept would appear to integrate nicely with all the Metabox upload fields, for example:

https://docs.metabox.io/fields/image-upload/

where the array attribute 'upload_dir' uses/creates a "home" folder which could be a user's wordpress ID or an secure, unique algorithmic hash.

Thanks,
David

Hi Anh,

Thanks for the pointers, I have come across those before, although I'm interested in logical and structural separation.

Would this pseudocode work, and could Metabox handle being returned an error?

array(
    'upload_dir' => fnCreateOrReturnFolder
)

fnCreateReturnFolder {
    $userdir = get_current_user_id()
    if $userdir != 0 {
        $userdirpath = '/path/to/users/folders/' . $userdir
        if ( !file_exists($userdirpath) ) {
            if ( wp_mkdir_p( $userdirpath ) ) {
                return $userdirpath
            }
        }
    }
    return 'error'
}

Thanks Anh,

I had shown your suggestion in my snippet:

'upload_dir' => fnCreateOrReturnFolder

Although I'm interested in how Metabox would handle an error creating or retrieving the folder, whereupon in the snippet I have set it to return 'error' instead of the folder path?

Hi Anh,

Great feature!

I would like to use it in a multisite installation. Is there a way to upload it to an upload folder within that subsite, without hardcoding the sitenumber in the path?

For multisite installation the regualar path is ../wp-contents/uploads/sites/<sitenumber>/<foldername>.
Is it possible to specify as path ../wp-contents/uploads/<foldername>, and that automatically the /sites/ and sitenumber are added?

It would make setting up a new subsite so much easier...
