Feature request: Allow blank fields and/or fallbacks

[tobaco]

It would be a good addition to have an option to allow fields to be blank and just replace them with an empty string.

Additionally it would be great to have the option to specify a fallback value, if a field is blank.

This could look like this:

{$page->my_field|my-fallback}

So if the field my_field is empty, it should be replaced by my-fallback.

Thanks!

@tobaco - you can already do the second option using PW's built-in syntax:

{$page->get('my_field|my-fallback')}

Would that take care of all your needs in reality because I can't really see why you'd want part of the name left blank if a field is blank.

Thanks for the hint! Your suggestion would mean that my-fallback is a different field, right?
I meant it more as a string, which is used when the field is empty.

I can't really see why you'd want part of the name left blank if a field is blank.

I have the case that I want to automatically rename profile pictures of users so that their name is in the file name ({$page->name}-{$page->img_credits}). In some cases, users must also provide information about the photographer (img_credits) if the image is used publicly. However, this information is optional. However, if the credits are there, they should be included in the file name. At the moment, if the img_credits field is empty, the image is not renamed at all, but only has upload-tmp appended to the original file name. However, I would like to achieve that at least the name of the user is used as the file name or that the value of the img_credits field is replaced by private (fallback from fiel name format config) or something similar. A fallback to another field would probably not help ...

The simplest solution would probably be to omit my desired string fallback option and add an option (checkbox) in the settings that allows empty fields. In the code you would then check whether at least 1 field from the file name configuration is filled and then rename the file and simply omit empty fields. If all fields from the configuration are empty, then the upload-tmp variant would be executed.

Thanks!
