Package validator implements value validations for structs and individual fields based on tags.
It has the following **unique** features:
- Cross Field and Cross Struct validations by using validation tags or custom validators.
- Slice, Array and Map diving, which allows any or all levels of a multidimensional field to be validated.
- Handles type interface by determining it's underlying type prior to validation.
- Handles custom field types such as sql driver Valuer see [Valuer](https://golang.org/src/database/sql/driver/types.go?s=1210:1293#L29)
- Alias validation tags, which allows for mapping of several validations to a single tag for easier defining of validations on structs
- Extraction of custom defined Field Name e.g. can specify to extract the JSON name while validating and have it available in the resulting FieldError
Installation
------------
Use go get.
go get gopkg.in/go-playground/validator.v8
or to update
go get -u gopkg.in/go-playground/validator.v8
Then import the validator package into your own code.
import "gopkg.in/go-playground/validator.v8"
Error Return Value
-------
Validation functions return type error
They return type error to avoid the issue discussed in the following, where err is always != nil:
* http://stackoverflow.com/a/29138676/3158232
* https://github.com/go-playground/validator/issues/134
validator only returns nil or ValidationErrors as type error; so in you code all you need to do
is check if the error returned is not nil, and if it's not type cast it to type ValidationErrors
like so:
```go
err := validate.Struct(mystruct)
validationErrors := err.(validator.ValidationErrors)
```
Usage and documentation
------
Please see http://godoc.org/gopkg.in/go-playground/validator.v8 for detailed usage docs.
##### Examples:
Struct & Field validation
```go
package main
import (
"fmt"
"gopkg.in/go-playground/validator.v8"
)
// User contains user information
type User struct {
FirstName string `validate:"required"`
LastName string `validate:"required"`
Age uint8 `validate:"gte=0,lte=130"`
Email string `validate:"required,email"`
FavouriteColor string `validate:"hexcolor|rgb|rgba"`
Addresses []*Address `validate:"required,dive,required"` // a person can have a home and cottage...
}
// Address houses a users address information
type Address struct {
Street string `validate:"required"`
City string `validate:"required"`
Planet string `validate:"required"`
Phone string `validate:"required"`
}
var validate *validator.Validate
func main() {
config := &validator.Config{TagName: "validate"}
validate = validator.New(config)
validateStruct()
validateField()
}
func validateStruct() {
address := &Address{
Street: "Eavesdown Docks",
Planet: "Persphone",
Phone: "none",
}
user := &User{
FirstName: "Badger",
LastName: "Smith",
Age: 135,
Email: "Badger.Smith@gmail.com",
FavouriteColor: "#000",
Addresses: []*Address{address},
}
// returns nil or ValidationErrors ( map[string]*FieldError )
errs := validate.Struct(user)
if errs != nil {
fmt.Println(errs) // output: Key: "User.Age" Error:Field validation for "Age" failed on the "lte" tag
// Key: "User.Addresses[0].City" Error:Field validation for "City" failed on the "required" tag
err := errs.(validator.ValidationErrors)["User.Addresses[0].City"]
fmt.Println(err.Field) // output: City
fmt.Println(err.Tag) // output: required
fmt.Println(err.Kind) // output: string
fmt.Println(err.Type) // output: string
fmt.Println(err.Param) // output:
fmt.Println(err.Value) // output:
// from here you can create your own error messages in whatever language you wish
return
}
// save user to database
}
func validateField() {
myEmail := "joeybloggs.gmail.com"
errs := validate.Field(myEmail, "required,email")
if errs != nil {
fmt.Println(errs) // output: Key: "" Error:Field validation for "" failed on the "email" tag
return
}
// email ok, move on
}
```
Custom Field Type
```go
package main
import (
"database/sql"
"database/sql/driver"
"fmt"
"reflect"
"gopkg.in/go-playground/validator.v8"
)
// DbBackedUser User struct
type DbBackedUser struct {
Name sql.NullString `validate:"required"`
Age sql.NullInt64 `validate:"required"`
}
func main() {
config := &validator.Config{TagName: "validate"}
validate := validator.New(config)
// register all sql.Null* types to use the ValidateValuer CustomTypeFunc
validate.RegisterCustomTypeFunc(ValidateValuer, sql.NullString{}, sql.NullInt64{}, sql.NullBool{}, sql.NullFloat64{})
x := DbBackedUser{Name: sql.NullString{String: "", Valid: true}, Age: sql.NullInt64{Int64: 0, Valid: false}}
errs := validate.Struct(x)
if len(errs.(validator.ValidationErrors)) > 0 {
fmt.Printf("Errs:\n%+v\n", errs)
}
}
// ValidateValuer implements validator.CustomTypeFunc
func ValidateValuer(field reflect.Value) interface{} {
if valuer, ok := field.Interface().(driver.Valuer); ok {
val, err := valuer.Value()
if err == nil {
return val
}
// handle the error how you want
}
return nil
}
```
Struct Level Validation
```go
package main
import (
"fmt"
"reflect"
"gopkg.in/go-playground/validator.v8"
)
// User contains user information
type User struct {
FirstName string `json:"fname"`
LastName string `json:"lname"`
Age uint8 `validate:"gte=0,lte=130"`
Email string `validate:"required,email"`
FavouriteColor string `validate:"hexcolor|rgb|rgba"`
Addresses []*Address `validate:"required,dive,required"` // a person can have a home and cottage...
}
// Address houses a users address information
type Address struct {
Street string `validate:"required"`
City string `validate:"required"`
Planet string `validate:"required"`
Phone string `validate:"required"`
}
var validate *validator.Validate
func main() {
config := &validator.Config{TagName: "validate"}
validate = validator.New(config)
validate.RegisterStructValidation(UserStructLevelValidation, User{})
validateStruct()
}
// UserStructLevelValidation contains custom struct level validations that don't always
// make sense at the field validation level. For Example this function validates that either
// FirstName or LastName exist; could have done that with a custom field validation but then
// would have had to add it to both fields duplicating the logic + overhead, this way it's
// only validated once.
//
// NOTE: you may ask why wouldn't I just do this outside of validator, because doing this way
// hooks right into validator and you can combine with validation tags and still have a
// common error output format.
func UserStructLevelValidation(v *validator.Validate, structLevel *validator.StructLevel) {
user := structLevel.CurrentStruct.Interface().(User)
if len(user.FirstName) == 0 && len(user.LastName) == 0 {
structLevel.ReportError(reflect.ValueOf(user.FirstName), "FirstName", "fname", "fnameorlname")
structLevel.ReportError(reflect.ValueOf(user.LastName), "LastName", "lname", "fnameorlname")
}
// plus can to more, even with different tag than "fnameorlname"
}
func validateStruct() {
address := &Address{
Street: "Eavesdown Docks",
Planet: "Persphone",
Phone: "none",
City: "Unknown",
}
user := &User{
FirstName: "",
LastName: "",
Age: 45,
Email: "Badger.Smith@gmail.com",
FavouriteColor: "#000",
Addresses: []*Address{address},
}
// returns nil or ValidationErrors ( map[string]*FieldError )
errs := validate.Struct(user)
if errs != nil {
fmt.Println(errs) // output: Key: 'User.LastName' Error:Field validation for 'LastName' failed on the 'fnameorlname' tag
// Key: 'User.FirstName' Error:Field validation for 'FirstName' failed on the 'fnameorlname' tag
err := errs.(validator.ValidationErrors)["User.FirstName"]
fmt.Println(err.Field) // output: FirstName
fmt.Println(err.Tag) // output: fnameorlname
fmt.Println(err.Kind) // output: string
fmt.Println(err.Type) // output: string
fmt.Println(err.Param) // output:
fmt.Println(err.Value) // output:
// from here you can create your own error messages in whatever language you wish
return
}
// save user to database
}

Complimentary Software
----------------------
Here is a list of software that compliments using this library either pre or post validation.
* [Gorilla Schema](https://github.com/gorilla/schema) - Package gorilla/schema fills a struct with form values.
* [Conform](https://github.com/leebenson/conform) - Trims, sanitizes & scrubs data based on struct tags.
How to Contribute
------
There will always be a development branch for each version i.e. `v1-development`. In order to contribute,
please make your pull requests against those branches.
If the changes being proposed or requested are breaking changes, please create an issue, for discussion
or create a pull request against the highest development branch for example this package has a
v1 and v1-development branch however, there will also be a v2-development branch even though v2 doesn't exist yet.
I strongly encourage everyone whom creates a custom validation function to contribute them and
help make this package even better.

Package validator implements value validations for structs and individual fields
based on tags.
It can also handle Cross-Field and Cross-Struct validation for nested structs
and has the ability to dive into arrays and maps of any type.
Why not a better error message?
Because this library intends for you to handle your own error messages.
Why should I handle my own errors?
Many reasons. We built an internationalized application and needed to know the
field, and what validation failed so we could provide a localized error.
if fieldErr.Field == "Name" {
switch fieldErr.ErrorTag
case "required":
return "Translated string based on field + error"
default:
return "Translated string based on field"
}
Validation Functions Return Type error
Doing things this way is actually the way the standard library does, see the
file.Open method here:
https://golang.org/pkg/os/#Open.
The authors return type "error" to avoid the issue discussed in the following,
where err is always != nil:
http://stackoverflow.com/a/29138676/3158232
https://github.com/go-playground/validator/issues/134
Validator only returns nil or ValidationErrors as type error; so, in your code
all you need to do is check if the error returned is not nil, and if it's not
type cast it to type ValidationErrors like so err.(validator.ValidationErrors).
Custom Functions
Custom functions can be added. Example:
// Structure
func customFunc(v *Validate, topStruct reflect.Value, currentStructOrField reflect.Value, field reflect.Value, fieldType reflect.Type, fieldKind reflect.Kind, param string) bool {
if whatever {
return false
}
return true
}
validate.RegisterValidation("custom tag name", customFunc)
// NOTES: using the same tag name as an existing function
// will overwrite the existing one
Cross-Field Validation
Cross-Field Validation can be done via the following tags:
- eqfield
- nefield
- gtfield
- gtefield
- ltfield
- ltefield
- eqcsfield
- necsfield
- gtcsfield
- ftecsfield
- ltcsfield
- ltecsfield
If, however, some custom cross-field validation is required, it can be done
using a custom validation.
Why not just have cross-fields validation tags (i.e. only eqcsfield and not
eqfield)?
The reason is efficiency. If you want to check a field within the same struct
"eqfield" only has to find the field on the same struct (1 level). But, if we
used "eqcsfield" it could be multiple levels down. Example:
type Inner struct {
StartDate time.Time
}
type Outer struct {
InnerStructField *Inner
CreatedAt time.Time `validate:"ltecsfield=InnerStructField.StartDate"`
}
now := time.Now()
inner := &Inner{
StartDate: now,
}
outer := &Outer{
InnerStructField: inner,
CreatedAt: now,
}
errs := validate.Struct(outer)
// NOTE: when calling validate.Struct(val) topStruct will be the top level struct passed
// into the function
// when calling validate.FieldWithValue(val, field, tag) val will be
// whatever you pass, struct, field...
// when calling validate.Field(field, tag) val will be nil
Multiple Validators
Multiple validators on a field will process in the order defined. Example:
type Test struct {
Field `validate:"max=10,min=1"`
}
// max will be checked then min
Bad Validator definitions are not handled by the library. Example:
type Test struct {
Field `validate:"min=10,max=0"`
}
// this definition of min max will never succeed
Using Validator Tags
Baked In Cross-Field validation only compares fields on the same struct.
If Cross-Field + Cross-Struct validation is needed you should implement your
own custom validator.
Comma (",") is the default separator of validation tags. If you wish to
have a comma included within the parameter (i.e. excludesall=,) you will need to
use the UTF-8 hex representation 0x2C, which is replaced in the code as a comma,
so the above will become excludesall=0x2C.
type Test struct {
Field `validate:"excludesall=,"` // BAD! Do not include a comma.
Field `validate:"excludesall=0x2C"` // GOOD! Use the UTF-8 hex representation.
}
Pipe ("|") is the default separator of validation tags. If you wish to
have a pipe included within the parameter i.e. excludesall=| you will need to
use the UTF-8 hex representation 0x7C, which is replaced in the code as a pipe,
so the above will become excludesall=0x7C
type Test struct {
Field `validate:"excludesall=|"` // BAD! Do not include a a pipe!
Field `validate:"excludesall=0x7C"` // GOOD! Use the UTF-8 hex representation.
}
Baked In Validators and Tags
Here is a list of the current built in validators:
Skip Field
Tells the validation to skip this struct field; this is particularly
handy in ignoring embedded structs from being validated. (Usage: -)
Usage: -
Or Operator
This is the 'or' operator allowing multiple validators to be used and
accepted. (Usage: rbg|rgba) <-- this would allow either rgb or rgba
colors to be accepted. This can also be combined with 'and' for example
( Usage: omitempty,rgb|rgba)
Usage: |
StructOnly
When a field that is a nested struct is encountered, and contains this flag
any validation on the nested struct will be run, but none of the nested
struct fields will be validated. This is usefull if inside of you program
you know the struct will be valid, but need to verify it has been assigned.
NOTE: only "required" and "omitempty" can be used on a struct itself.
Usage: structonly
NoStructLevel
Same as structonly tag except that any struct level validations will not run.
Usage: nostructlevel
Exists
Is a special tag without a validation function attached. It is used when a field
is a Pointer, Interface or Invalid and you wish to validate that it exists.
Example: want to ensure a bool exists if you define the bool as a pointer and
use exists it will ensure there is a value; couldn't use required as it would
fail when the bool was false. exists will fail is the value is a Pointer, Interface
or Invalid and is nil.
Usage: exists
Omit Empty
Allows conditional validation, for example if a field is not set with
a value (Determined by the "required" validator) then other validation
such as min or max won't run, but if a value is set validation will run.
Usage: omitempty
Dive
This tells the validator to dive into a slice, array or map and validate that
level of the slice, array or map with the validation tags that follow.
Multidimensional nesting is also supported, each level you wish to dive will
require another dive tag.
Usage: dive
Example #1
[][]string with validation tag "gt=0,dive,len=1,dive,required"
// gt=0 will be applied to []
// len=1 will be applied to []string
// required will be applied to string
Example #2
[][]string with validation tag "gt=0,dive,dive,required"
// gt=0 will be applied to []
// []string will be spared validation
// required will be applied to string
Required
This validates that the value is not the data types default zero value.
For numbers ensures value is not zero. For strings ensures value is
not "". For slices, maps, pointers, interfaces, channels and functions
ensures the value is not nil.
Usage: required
Length
For numbers, max will ensure that the value is
equal to the parameter given. For strings, it checks that
the string length is exactly that number of characters. For slices,
arrays, and maps, validates the number of items.
Usage: len=10
Maximum
For numbers, max will ensure that the value is
less than or equal to the parameter given. For strings, it checks
that the string length is at most that number of characters. For
slices, arrays, and maps, validates the number of items.
Usage: max=10
Mininum
For numbers, min will ensure that the value is
greater or equal to the parameter given. For strings, it checks that
the string length is at least that number of characters. For slices,
arrays, and maps, validates the number of items.
Usage: min=10
Equals
For strings & numbers, eq will ensure that the value is
equal to the parameter given. For slices, arrays, and maps,
validates the number of items.
Usage: eq=10
Not Equal
For strings & numbers, ne will ensure that the value is not
equal to the parameter given. For slices, arrays, and maps,
validates the number of items.
Usage: ne=10
Greater Than
For numbers, this will ensure that the value is greater than the
parameter given. For strings, it checks that the string length
is greater than that number of characters. For slices, arrays
and maps it validates the number of items.
Example #1
Usage: gt=10
Example #2 (time.Time)
For time.Time ensures the time value is greater than time.Now.UTC().
Usage: gt
Greater Than or Equal
Same as 'min' above. Kept both to make terminology with 'len' easier.
Example #1
Usage: gte=10
Example #2 (time.Time)
For time.Time ensures the time value is greater than or equal to time.Now.UTC().
Usage: gte
Less Than
For numbers, this will ensure that the value is less than the parameter given.
For strings, it checks that the string length is less than that number of
characters. For slices, arrays, and maps it validates the number of items.
Example #1
Usage: lt=10
Example #2 (time.Time)
For time.Time ensures the time value is less than time.Now.UTC().
Usage: lt
Less Than or Equal
Same as 'max' above. Kept both to make terminology with 'len' easier.
Example #1
Usage: lte=10
Example #2 (time.Time)
For time.Time ensures the time value is less than or equal to time.Now.UTC().
Usage: lte
Field Equals Another Field
This will validate the field value against another fields value either within
a struct or passed in field.
Example #1:
// Validation on Password field using:
Usage: eqfield=ConfirmPassword
Example #2:
// Validating by field:
validate.FieldWithValue(password, confirmpassword, "eqfield")
Field Equals Another Field (relative)
This does the same as eqfield except that it validates the field provided relative
to the top level struct.
Usage: eqcsfield=InnerStructField.Field)
Field Does Not Equal Another Field
This will validate the field value against another fields value either within
a struct or passed in field.
Examples:
// Confirm two colors are not the same:
//
// Validation on Color field:
Usage: nefield=Color2
// Validating by field:
validate.FieldWithValue(color1, color2, "nefield")
Field Does Not Equal Another Field (relative)
This does the same as nefield except that it validates the field provided
relative to the top level struct.
Usage: necsfield=InnerStructField.Field
Field Greater Than Another Field
Only valid for Numbers and time.Time types, this will validate the field value
against another fields value either within a struct or passed in field.
usage examples are for validation of a Start and End date:
Example #1:
// Validation on End field using:
validate.Struct Usage(gtfield=Start)
Example #2:
// Validating by field:
validate.FieldWithValue(start, end, "gtfield")
Field Greater Than Another Relative Field
This does the same as gtfield except that it validates the field provided
relative to the top level struct.
Usage: gtcsfield=InnerStructField.Field
Field Greater Than or Equal To Another Field
Only valid for Numbers and time.Time types, this will validate the field value
against another fields value either within a struct or passed in field.
usage examples are for validation of a Start and End date:
Example #1:
// Validation on End field using:
validate.Struct Usage(gtefield=Start)
Example #2:
// Validating by field:
validate.FieldWithValue(start, end, "gtefield")
Field Greater Than or Equal To Another Relative Field
This does the same as gtefield except that it validates the field provided relative
to the top level struct.
Usage: gtecsfield=InnerStructField.Field
Less Than Another Field
Only valid for Numbers and time.Time types, this will validate the field value
against another fields value either within a struct or passed in field.
usage examples are for validation of a Start and End date:
Example #1:

Alias Validators and Tags
NOTE: When returning an error, the tag returned in "FieldError" will be
the alias tag unless the dive tag is part of the alias. Everything after the
dive tag is not reported as the alias tag. Also, the "ActualTag" in the before
case will be the actual tag within the alias that failed.
Here is a list of the current built in alias tags:
"iscolor"
alias is "hexcolor|rgb|rgba|hsl|hsla" (Usage: iscolor)
Validator notes:
regex
a regex validator won't be added because commas and = signs can be part
of a regex which conflict with the validation definitions. Although
workarounds can be made, they take away from using pure regex's.
Furthermore it's quick and dirty but the regex's become harder to
maintain and are not reusable, so it's as much a programming philosiphy
as anything.
In place of this new validator functions should be created; a regex can
be used within the validator function and even be precompiled for better
efficiency within regexes.go.
And the best reason, you can submit a pull request and we can keep on
adding to the validation library of this package!
Panics
This package panics when bad input is provided, this is by design, bad code like
that should not make it to production.
type Test struct {
TestField string `validate:"nonexistantfunction=1"`
}
t := &Test{
TestField: "Test"
