Functions

func Equal

func Equal(value1 string, value2 string) bool

checks to see if two fields are equal

func Matches

func Matches(value string, rx *regexp.Regexp) bool

checks if field matches regular expression

func MaxChars

func MaxChars(value string, n int) bool

checks for max number of characters

func MinChars

func MinChars(value string, n int) bool

checks for min number of characters

func NotBlank

func NotBlank(value string) bool

Types

type Validator

type Validator struct {
	NonFieldErrors []string
	FieldErrors    map[string]string
}

FielErrors are associated with a form field and NonFieldErrors are just general form errors

func (*Validator) AddFieldError

func (v *Validator) AddFieldError(key, message string)

adds a new field error if it does not already exist

func (*Validator) AddNonFieldError

func (v *Validator) AddNonFieldError(message string)

create a NonFieldError

func (*Validator) CheckField

func (v *Validator) CheckField(ok bool, key, message string)

checks for a specific field error

func (*Validator) Valid

func (v *Validator) Valid() bool

checks if form is valid
