[4.0.2]: Twig variable in asset folder path causes upload button to not be displayed if folder doesn't exist

[richhayler]

What happened?

Description

Upload button not displayed on file selection modal due to twig variable used in sub folder path for a path that doesn't exist, e.g. if using {slug} in the folder path

Steps to reproduce

• Create a new filesystem
• Create a new volume that references the filesystem
• Create a new field that points to the volume
• For the field settings....
• Select "restrict assets to a single location'
• Select folder location from the dropdown
• Add {slug} in the subfolder path
• Ensure "Allow sub folders" and "Allow uploading directly to the field" are both unchecked
• Save and assign field to entry type in a new section
• Create a new entry and click the asset file to upload a new file
• Modal is displayed without the upload button in the bottom left

Expected behavior

Event though the folder for the slug doesn't appear (as this would be created when the entry is created), the upload button should be displayed in the file selection modal.

Thanks for pointing that out! Just fixed for the next release.

Craft 4.0.3 is out now with that fix.

I have updated to 4.0.3 and it's now working as expected using {slug} in the sub folder path.

Should I be able to use access globalSet variables in the folder subpath? - e.g. I have a globalSet named "global" with a text field, "mytext" (which is a single word, no spaces)?

If I use {global.mytext} this results in an error stating that "the field’s Asset Location setting has an invalid subpath (“{global.domain}”)".

You would need to use normal Twig syntax for that ({{ global.mytext }}). The {shorthand} syntax is exclusively for properties of the entry being saved (or the Matrix block if the Assets field is nested in a Matrix field.)

Thank you for responding and providing those tips!
