Preview link broken on files uploaded with Dreamform (getkirby/kirby#6786)

[samlinck]

When clicking on the preview button nothing happens. The preview button of other files does work as expected.
When manually copying the file url the file can be accessed.

Also in the default mail message, nothing is said about a file being uploaded. Could be an enhancement to provide a link to the uploaded file?

In DreamForm 1.5.0 you can choose to add the files as attachment to the email. It's not possible to add the links to the email since the file is uploaded/created in Kirby after the email is send. See more here.

Honestly, I'm a bit confused about this report, it works fine on my environments - both with images and other file types.

Okay very nice that it will be available in 1.5.0!
It's indeed a strange bug, maybe some other plugin or setting is conflicting with it. I will let you know if I know some more.

So the weird thing is, that the preview button isn't a link for me.

I just found the same issue with some video files that were normally uploaded via the panel - unrelated to DreamForm. Seems like a Core bug?

I had this issue in other contexts with Kirby one day ago. If you upload a file to a page with a blueprint, where the blueprint permisson for preview is set to false, then this happens.

Also the fiel preview urls follow some more conditions - see here https://github.com/getkirby/kirby/blob/eb47158e91e74184ab291ede020664f1d2829f74/src/Cms/File.php#L652
