During the development process, we often need to verify the data entered by the user. When developing in Go language, go-playground/validator/v10 is a very easy-to-use verification library. It provides rich verification rules and concise usage methods, which can help us quickly and effectively verify the legality of data. In this article, PHP editor Xinyi will introduce how to use go-playground/validator/v10 to verify two fields, and give detailed code examples. Let’s learn together!
Need to check that at least one field should exist email, at least one phone number is required
Currently I have a custom validator
func validateEmailPhone(fl validator.FieldLevel) bool { user := fl.Top().Interface().(models.User) validate := validator.Validate{} if user.Email == "" && user.Phone == "" { return false } if user.Email != "" { if err := validate.Var(user.Email, "email"); err != nil { return false } } if user.Phone != "" { if err := validate.Var(user.Phone, "e164"); err != nil { return false } } return true }
But very panic
User is gorm model
How to check these two fields in this case
There are Lots of conditionsrequired
validator## tags in #.
In your case you may want
required_without_all
omitempty.
required_without_all - Makes a field required if all fields in the list are empty.
omitempty - Only the field is allowed to be empty.
