A good place to activate this is a package init function or the main() function. + +`SetNilPtrAllowedByRequired` causes validation to pass when struct fields marked by `required` are set to nil. This is disabled by default for consistency, but some packages that need to be able to determine between `nil` and `zero value` state can use this.

+Here's some code to explain it: +```go +// this struct definition will fail govalidator.ValidateStruct() (and the field values do not matter): +type exampleStruct struct { + Name string `` + Email string `valid:"email"` +} + +// this, however, will only fail when Email is empty or an invalid email address: +type exampleStruct2 struct { + Name string `valid:"-"` + Email string `valid:"email"` +} + +// lastly, this will only fail when Email is an invalid email address but not when it's empty: +type exampleStruct2 struct { + Name string `valid:"-"` + Email string `valid:"email,optional"` +} +``` + +#### Recent breaking changes (see [#123](https://github.com/asaskevich/govalidator/pull/123)) +##### Custom validator function signature +A context was added as the second parameter, for

+println(govalidator.IsType(&i, "*int")) +``` + +IsType can be used through the tag `type` which is essential for map validation: +```go +type User struct { + Name string `valid:"type(string)"` + Age int `valid:"type(int)"` + Meta interface{} `valid:"type(string)"` +} +result, err := govalidator.ValidateStruct(User{"Bob", 20, "meta"}) +if err != nil { + println("error: " + err.Error()) +} +println(result) +``` +###### ToString +```go +type User struct { + FirstName string + LastName string +} + +str := govalidator.ToString(&User{"John", "Juan"}) +println(str) +``` +###### Each, Map, Filter, Count for slices +Each iterates over the slice/array and calls Iterator for every item +```go +data := []interface{}{1, 2, 3, 4, 5} +var fn govalidator.Iterator = func(value interface{}, index int) { + println(value.(int)) +} +govalidator.Each(data, fn) +``` +```go +data := []interface{}{1, 2, 3, 4, 5} +var fn govalidator.ResultIterator = func(value interface{}, index int) interface{} { +

govalidator.ConditionIterator = func(value interface{}, index int) bool { + return value.(int)%2 == 0 +} +_ = govalidator.Filter(data, fn) // result = []interface{}{2, 4, 6, 8, 10} +_ = govalidator.Count(data, fn) // result = 5 +``` +###### ValidateStruct [#2](https://github.com/asaskevich/govalidator/pull/2) +If you want to validate structs, you can use tag `valid` for any field in your structure. All validators used with this field in one tag are separated by comma. If you want to skip validation, place `-` in your tag. If you need a validator that is not on the list below, you can add it like this: +```go +govalidator.TagMap["duck"] = govalidator.Validator(func(str string) bool { + return str == "duck" +}) +``` +For completely custom validators (interface-based), see below. + +Here is a list of available validators for struct fields (validator - used function): +```go +"email": IsEmail, +"url": IsURL, +"dialstring": IsDialString, +"requrl": IsRequestURL, +"requri": IsRequestURI, +"alpha": IsAlpha, +"utfletter": IsUTFLetter, +"alphanum": IsAlphanumeric, +"utfletternum": IsUTFLetterNumeric, +"numeric": IsNumeric, +"utfnumeric": IsUTFNumeric, +"utfdigit": IsUTFDigit, +"hexadecimal": IsHexadecimal, +"hexcolor": IsHexcolor, +"rgbcolor": IsRGBcolor, +"lowercase": IsLowerCase, +"uppercase": IsUpperCase, +"int": IsInt, +"float": IsFloat, +"null": IsNull, +"uuid": IsUUID, +"uuidv3": IsUUIDv3, +"uuidv4": IsUUIDv4, +"uuidv5": IsUUIDv5, +"creditcard": IsCreditCard, +"isbn10": IsISBN10, +"isbn13": IsISBN13, +"json": IsJSON, +"multibyte": IsMultibyte, +"ascii": IsASCII, +"printableascii": IsPrintableASCII, +"fullwidth": IsFullWidth, +"halfwidth": IsHalfWidth, +"variablewidth": IsVariableWidth, +"base64": IsBase64, +"datauri": IsDataURI, +"ip": IsIP, +"port": IsPort, +"ipv4": IsIPv4, +"ipv6": IsIPv6, +"dns": IsDNSName, +"host": IsHost, +"mac": IsMAC, +"latitude": IsLatitude, +"longitude": IsLongitude, +"ssn": IsSSN, +"semver": IsSemver, +"rfc3339": IsRFC3339, +"rfc3339WithoutZone": IsRFC3339WithoutZone, +"ISO3166Alpha2": IsISO3166Alpha2, +"ISO3166Alpha3": IsISO3166Alpha3, +"ulid": IsULID, +``` +Validators with parameters + +```go +"range(min|max)": Range, +"length(min|max)": ByteLength, +"runelength(min|max)": RuneLength, +"stringlength(min|max)": StringLength, +"matches(pattern)": StringMatches, +"in(string1|string2|...|stringN)": IsIn, +"rsapub(keylength)" : IsRsaPub, +"minstringlength(int): MinStringLength, +"maxstringlength(int): MaxStringLength, +``` +Validators with parameters for any type + +```go +"type(type)": IsType, +``` + +And here is small example of usage: +```go +type Post struct { + Title string `valid:"alphanum,required"` + Message string `valid:"duck,ascii"` + Message2 string `valid:"animal(dog)"` + AuthorIP string `valid:"ipv4"` + Date string `valid:"-"` +} +post := &Post{ + Title: "My Example Post", + Message: "duck", + Message2: "dog", + AuthorIP: "123.234.54.3", +} + +// Add your own struct validation tags +govalidator.TagMap["duck"] = govalidator.Validator(func(str string) bool { + return str == "duck" +}) + +// Add your own struct validation tags with parameter +govalidator.ParamTagMap["animal"] = govalidator.ParamValidator(func(str string, params ...string) bool { + species := params[0] + return str == species +}) +govalidator.ParamTagRegexMap["animal"] = regexp.MustCompile("^animal\\((\\w+)\\)$") + +result, err := govalidator.ValidateStruct(post) +if err != nil { + println("error: " + err.Error()) +} +println(result) +``` +###### ValidateMap [#2](https://github.com/asaskevich/govalidator/pull/338) +If you want to validate maps, you can use the map to be validated and a validation map that contain the same tags used in ValidateStruct, both maps have to be in the form `map[string]interface{}` + +So here is small example of usage: +```go +var mapTemplate = map[string]interface{}{ + "name":"required,alpha", + "family":"required,alpha", + "email":"required,email", + "cell-phone":"numeric", + "address":map[string]interface{}{ + "line1":"required,alphanum", + "line2":"alphanum", + "postal-code":"numeric", + }, +} + +var inputMap = map[string]interface{}{ + "name":"Bob", + "family":"Smith", + "email":"foo@bar.baz", + "address":map[string]interface{}{ + "line1":"", + "line2":"", + "postal-code":"", + }, +} + +result, err := govalidator.ValidateMap(inputMap, mapTemplate) +if err != nil { + println("error: " + err.Error()) +} +println(result) +``` + +###### WhiteList +```go +// Remove all characters from string ignoring characters between "a" and "z" +println(govalidator.WhiteList("a3a43a5a4a3a2a23a4a5a4a3a4", "a-z") == "aaaaaaaaaaaa") +``` + +###### Custom validation functions +Custom validation using your own domain specific validators is also available - here's an example of how to use it: +```go +import "github.com/asaskevich/govalidator" + +type CustomByteArray [6]byte // custom types are supported and can be validated + +type StructWithCustomByteArray struct { + ID CustomByteArray `valid:"customByteArrayValidator,customMinLengthValidator"` // multiple custom validators are possible as well and will be evaluated in sequence + Email string `valid:"email"` + CustomMinLength int `valid:"-"` +} + +govalidator.CustomTypeTagMap.Set("customByteArrayValidator", func(i interface{}, context interface{}) bool { + switch v := context.(type) { // you can type switch on the context interface being validated + case StructWithCustomByteArray: + // you can check and validate against some other field in the context, + // return early or not validate against the context at all – your choice + case SomeOtherType: + // ... + default: + // expecting some other type? Throw/panic here or continue + } + + switch v := i.(type) { // type switch on the struct field being validated + case CustomByteArray: + for _, e := range v { // this validator checks that the byte array is not empty, i.e. not all zeroes + if e != 0 { + return true + } + } + } + return false +}) +govalidator.CustomTypeTagMap.Set("customMinLengthValidator", func(i interface{}, context interface{}) bool { + switch v := context.(type) { // this validates a field against the value in another field, i.e. dependent validation + case StructWithCustomByteArray: + return len(v.ID) >= v.CustomMinLength + } + return false +}) +``` + +###### Loop over Error() +By default .Error() returns all errors in a single String. To access each error you can do this: +```go + if err != nil { + errs := err.(govalidator.Errors).Errors() + for _, e := range errs { + fmt.Println(e.Error()) + } + } +``` + +###### Custom error messages +Custom error messages are supported via annotations by adding the `~` separator - here's an example of how to use it: +```go +type Ticket struct { + Id int64 `json:"id"` + FirstName string `json:"firstname" valid:"required~First name is blank"` +} +``` + +#### Notes +Documentation is available here: [godoc.org](https://godoc.org/github.com/asaskevich/govalidator). +Full information about code coverage is also available here: [govalidator on gocover.io](http://gocover.io/github.com/asaskevich/govalidator). + +#### Support +If you do have a contribution to the package, feel free to create a Pull Request or an Issue. + +#### What to contribute +If you don't know what to do, there are some features and functions that need to be done + +- [ ] Refactor code +- [ ] Edit docs and [README](https://github.com/asaskevich/govalidator/README.md): spellcheck, grammar and typo check +- [ ] Create actual list of contributors and projects that currently using this package +- [ ] Resolve [issues and bugs](https://github.com/asaskevich/govalidator/issues) +- [ ] Update actual [list of functions](https://github.com/asaskevich/govalidator#list-of-functions) +- [ ] Update [list of validators](https://github.com/asaskevich/govalidator#validatestruct-2) that available for `ValidateStruct` and add new +- [ ] Implement new validators: `IsFQDN`, `IsIMEI`, `IsPostalCode`, `IsISIN`, `IsISRC` etc +- [x] Implement [validation by maps](https://github.com/asaskevich/govalidator/issues/224) +- [ ] Implement fuzzing testing +- [ ] Implement some struct/map/array utilities +- [ ] Implement map/array validation +- [ ] Implement benchmarking +- [ ] Implement batch of examples +- [ ] Look at forks for new features and fixes + +#### Advice +Feel free to create what you want, but keep in mind when you implement new features: +- Code must be clear and readable, names of variables/constants clearly describes what they are doing +- Public functions must be documented and described in source file and added to README.md to the list of available functions +- There are must be unit-tests for any new functions and improvements + +## Credits +### Contributors + +This project exists thanks to all the people who contribute.
