MinChars() returns true if the length of the input string is at least n.

func NotBlank ¶

func NotBlank(value string) bool

Types ¶

type Validator ¶

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

Define a new Validator type which contains a map of validation errors for form data.

func (*Validator) AddFieldError ¶

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

AddFieldError() adds a [form field name : error message] mapping to the FieldErrors map, so long as an entry does not already exist.

func (*Validator) AddNonFieldError ¶

func (v *Validator) AddNonFieldError(message string)

AddNonFieldError adds an error message to the NonFieldErrors string array, which stores error messages for validation errors not related to the form field data.

func (*Validator) CheckField ¶

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

CheckField() adds an error message to the FieldError map only if the validation check is not 'ok'.

func (*Validator) Valid ¶

func (v *Validator) Valid() bool

Valid() returns true if the FieldErrors map contains no entries.
