func RegisterJSONTagNameFormatter

func RegisterJSONTagNameFormatter() string

RegisterJSONTagNameFormatter sets a custom tag name function for JSON binding validation.

This function configures the validator to use the `json` struct tag as the field name when returning validation errors. Specifically, it affects the output of FieldError.Field(), so that it returns the JSON field name (e.g., `title`) instead of the Go struct field name (e.g., `Title`).

This improves the clarity of validation error messages when working with JSON APIs.
