The digits
checker checks if the given string consists of only digit characters. If the string contains non-digit characters, the checker will return the NOT_DIGITS
result. Here is an example:
type User struct {
Id string `checkers:"digits"`
}
user := &User{
Id: "1234",
}
_, valid := checker.Check(user)
if !valid {
// Send the mistakes back to the user
}
In your custom checkers, you can call the digits
checker function IsDigits
to validate the user input. Here is an example:
result := checker.IsDigits("1234")
if result != checker.ResultValid {
// Send the mistakes back to the user
}
