Make sure you configure the upload permission on the permissions page as well.
Mimetype regular expression
Regular expressions allow you a lot of freedom, but they are also very difficult to understand. Here are some pointers, but feel free to ask for help on the official Flarum forums.
In case you want to allow all regular file types including video, music, compressed files and images, use this:
A mimetype consists of a primary and secondary type. The primary type can be
application for instance.
The secondary is like a more detailed specification, eg
/, in regex you have to escape this character by using:
Disable or Force a particular adapter
In some circumstances, you may wish to either disable an adapter, or force the use of one. This is set in your root
For example, you may disable
(new FoF\Upload\Extend\Adapters()) ->disable('imgur'),
Chaining of multiple commands is also possible:
(new FoF\Upload\Extend\Adapters()) ->disable('imgur') ->disable('aws-s3'),
You may also force an adapter:
(new FoF\Upload\Extend\Adapters()) ->force('imgur'),
Adapter names currently available:
php flarum fof:upload you have a powerful tool in your hands to map uploads to posts and
clean up unused files. To do so there are two steps to take into consideration:
- Mapping (
--map) allows you to look through posts to identify whether which uploaded files have been used inside any posts, and store this information
- Clean up (
--cleanup-before=yyyy-mm-dd) grants you to ability to remove files that have been uploaded before the given time and haven't been mapped to any (existing) posts.
The intent of this command stems from the original concept of understand what uploads are used where and to allow removal of unused, stale files. You can run this command manually or as a cronjob.
Example 1; only mapping files:
php flarum fof:upload --map
Example 2; map and clean up
php flarum fof:upload --map --cleanup --cleanup-before="a month ago"
Once you're happy with how the command operates, you can append the flag
--force, which removes the need to confirm
php flarum fof:upload --map --cleanup --cleanup-before="last year" --force
The following (to resume) will happen when this command is put into a recurring cronjob:
- based on the interval of the cronjob (daily, weekly or however)
- the command will go over all uploads to discover in which posts they have been used
- delete those files that have been uploaded "last year" that have not been found in posts
- AWS S3: read the AWS S3 configuration page.
- Adding Templates: read the Custom Templates wiki page.
- Upgrading from flagrow/upload: read the wiki article.
