V15: Text character length validation should be more helpful

[alanwthom]

Which Umbraco version are you using? (Please write the exact version, example: 10.1.0)

v15

Bug summary

In versions 10-13, character length validation messages for text inputs (both textstring and textarea) show in the format "Maximum X characters, Y too many.". This provides content editors with the a) the maximum character limit on the input, and b) the number of characters they need to remove for their input to be accepted. Content editors are also provided with a live update of their input, for example "24 characters left."

In version 15, the validation message is "This field exceeds the allowed amount of characters". This provides no information to content editors as to a) what the character limit is, or b) what action they are required to take to have their input accepted. Content editors do not receive any other context of their input.

Suggestion: Update character length validation messages in v15 to match the previous structure of the error message, providing context to content editors as to why the field is invalid and how to fix their input, and reintroduce live character count message informaing content editors how many characters they have left.

Specifics

No response

Steps to reproduce

Add character validation to either default textarea or textstring data types and create content exceeding maximum number of allowed characters to show error message.

Hi there @alanwthom!

Firstly, a big thank you for raising this issue. Every piece of feedback we receive helps us to make Umbraco better.

We really appreciate your patience while we wait for our team to have a look at this but we wanted to let you know that we see this and share with you the plan for what comes next.

• We'll assess whether this issue relates to something that has already been fixed in a later version of the release that it has been raised for.
• If it's a bug, is it related to a release that we are actively supporting or is it related to a release that's in the end-of-life or security-only phase?
• We'll replicate the issue to ensure that the problem is as described.
• We'll decide whether the behavior is an issue or if the behavior is intended.

We wish we could work with everyone directly and assess your issue immediately but we're in the fortunate position of having lots of contributions to work with and only a few humans who are able to do it. We are making progress though and in the meantime, we will keep you in the loop and let you know when we have any questions.

Thanks, from your friendly Umbraco GitHub bot 🤖 🙂

Thanks @alanwthom. We have this as of 15.3:

But agree it would be nice to have the "how many are you over" part of the message too - will look to add that.

Ah, apologies @AndyButland - I didn't see this when searching for an existing issue. The reintroduction of "X too many" would be great, many thanks 🙏

This is fixed on the server-side only via #18722 and will be in 15.4. However we need to consider this on the front-end still, as currently the message presented there is different (coming from the UI library and without the tokens needed to replace with the numerical values).

The text used server-side which should align on the client is "The string length exceeds the maximum length of %0% characters, %1% too many"
