Overview

Package validators specifies that the variables, constants and functions to validate form data.

Index

• Constants
• func Email(s string) bool
• func Empty(s string) bool
• func IntegerInRange(s string, min int, max int) (error, bool)
• func IsInteger(s string) bool
• func LengthInRange(s string, min int, max int) bool
• func MaxLength(s string, max int) bool
• func MinLength(s string, min int) bool
• func NotBlank(data interface{}) bool
• func Password(s string) bool

Constants

const EmailPattern = "" /* 130-byte string literal not displayed */

EmailPattern stores a regular expression to validate the email address.

const NamePattern = "^[A-Za-z ]{5,}$"

NamePattern stores a regular expression to validate the name.

Functions

func Email

func Email(s string) bool

Email validates s email against the EMAIL_PATTERN set in the constant.

func Empty

func Empty(s string) bool

Empty validates s value by checking if it is blank.

func IntegerInRange

func IntegerInRange(s string, min int, max int) (error, bool)

IntegerInRange validates if s contains integral value, and its value lies between min and max values. This function returns error if s is non-integral.

func IsInteger

func IsInteger(s string) bool

IsInteger validates if s contains integral value.

func LengthInRange

func LengthInRange(s string, min int, max int) bool

LengthInRange validates if the length s is between specified min and max value.

func MaxLength

func MaxLength(s string, max int) bool

MaxLength validates if the length s is smaller than or equal to the specified max value.

func MinLength

func MinLength(s string, min int) bool

MinLength validates if the length of s is greater than or equal to the specified min value.

func NotBlank

func NotBlank(data interface{}) bool

NotBlank is the validation function for validating if the current field has a value or length greater than zero, or is not a space only string.

func Password

func Password(s string) bool

Password validates s password against the rules defined below.

upp: at least one upper case letter. low: at least one lower case letter. num: at least one digit. sym: at least one special character. tot: at least eight characters long. No empty string or whitespace.
