Identifying the First Failed Field During Validation (StopOnError=true)
I'm using the go-playground/validator library in Go, with the StopOnError=true setting enabled. During validation, I want to determine which field failed the validation and why. For example:
type SomeStruct struct { Name string validate:"required"Email stringvalidate:"required,email"`
}
d := &SomeStruct{ Name: "John", Email: "not an email", }
err := validate.Struct(d)
if err != nil {
// How can I extract the specific field (Email) that failed validation here?
}
`
In this case, I expect the validation to stop at the first error (StopOnError=true) and want to extract the following details:
-
The name of the failed field (e.g., Email).
-
The validation tag or reason for failure (e.g., email).
How can I achieve this with the go-playground/validator library
