@carcam one question, does joomla have some sort of default upload directory? cuz while testing the latest iteration of the quickstart i've noticed:

You have Mutagen enabled and your 'php' project type doesn't have `upload_dirs` set.
For faster startup and less disk usage, set upload_dirs to where your user-generated files are stored.
If this is intended you can disable this warning with `ddev config --disable-upload-dirs-warning`.

must have overlooked those on previous projects.

If there is not a default place for uploads/user-generated files, we can either leave this to pester the user to get it set where it belongs, or we can add --disable-upload-dirs-warning

did some quick research and it looks per default everything is uploaded into ./images

[carcam]

@rpkoller your research is right. The images folder at the root of Joomla is the common folder to place images for your content and it's kind of the place some extension developers storage user uploaded data when it's public.

Another interesting folder could be the media folder. Where extensions usually upload their public assets and finally a good one could be: templates/**/html/. Not sure if the upload_dirs support glob though...

i've quickly chatted with randy. wildcards dont work in this context here unfortunately. but out of curiosity, i knew it was possible to set more than one upload directory but was uncertain about the actual syntax. turns out all of the following works:

ddev config --project-type=php --webserver-type=apache-fpm --upload-dirs=images,templates/test
ddev config --project-type=php --webserver-type=apache-fpm --upload-dirs="images","templates/test"
ddev config --project-type=php --webserver-type=apache-fpm --upload-dirs='"images","templates/test"'

but in regards of the joomla quickstart guide i would vote to stick to only set the upload directory to the images directory?

@rpkoller simplicity is a plus when aiming quickstarts, so I see it ok.

Thanks for your work on this. It will get in!
