Some considerations:

  • The user / site builder is creating regular expressions
  • Do we want to validate beforehand if the regex is going to be valid?
  • Extremely expensive regexes can be forged. Do we assume users who can set #pattern can be trusted not to abuse that?

Maybe better to implement some API to allow contrib easily ship custom set of patterns

I think that would be an ok solution. We can ship with internal support for patterns for the relevant widgets, but not expose them in the UI.

Is this issue still valid? Client-side validation would probably improve usability so tagging it for usability review.

Assigned: dave reid » Unassigned

My conclusion after some research I did to this issue:

- Added "Needs usability review" as client-side validation could improve Field API usability.
- No activity in 4 years so removing assignment to Dave
- This issue was created (and commented) before we started using validation constraints on Entity API level. Using 2 different validation systems with no common settings can give unexpected or even invalid output.

IMO this issue needs to be closed (won't fix).

I came across this issue as it's blocking validation issues (like #2004136: Input validation is missing).

Thanks for looking at this. I don't know what to review here, so scaling back to just "usability" for now.
