Kirby file preview cannot find files with non-standard characters

Kirby 3
1

I have recently updated Kirby from 3.5.X → 3.6.3.1, along with PHP 7.4 → 8.1 and all the required php extensions etc.

We’re now experiencing an issue with Kirby locating files with non-standard characters, which worked perfectly fine with Kirby 3.5.X.

As an example, a file called my_filename+_image.png set in a file field type. Kirby is looking for the file without the + symbol in it, i.e. my_filename_image.png in the above case. If I remove the + from the filename, it does work as expected.

Can anyone identify what may have changed with Kirby or PHP that we can remedy without Find & Replace all affected files, as there are thousands of pages and files on this Kirby installation?

Many thanks in advance

How does this manifest? I’ve just tried by putting a

myfiles:
  - my_filename+_image.png

in a content file that was next to a my_filename+_image.png file and it seemed to work in 3.6.3.1:

echo $page->myFiles()->toFiles();

got me:

home/my_filename+_image.png

But that’s PHP 8.0 Same also in 8.1.4

What exactly is in your content file?

Hi @rasteiner

It’s actually not Kirby 3.6 - we’ve now identified the issue was present before, but no one ever noticed!

However, it is still an issue. I will revise the original post to reflect, but essentially:

  • the front-end is totally fine with the file name
  • the kirby methods work on the file
  • the panel accepts them for upload, but removes the + from the filename when saving the file.
  • blueprint fields will accept it being assigned, with or without the +

The issue only occurs when you click the file in the panel and effectively open it with file blueprint; at that point the file cannot be found.

These files must have been uploaded directly to the file system, not through the panel, so the + is still in the filename, and it’s just the single file view/blueprint that doesn’t like the character.

To reproduce, what happens if you click your file in the panel to open the “single file” view? Do you get an error?

I can reproduce that files with such filenames cannot be opened in file view.
