+Package validator
+================
+[![Build Status](https://travis-ci.org/bluesuncorp/validator.svg?branch=v5.1)](https://travis-ci.org/bluesuncorp/validator)
+[![GoDoc](https://godoc.org/gopkg.in/bluesuncorp/validator.v5?status.svg)](https://godoc.org/gopkg.in/bluesuncorp/validator.v5)
+
+Package validator implements value validations for structs and individual fields based on tags.
+It is also capable of Cross Field and Cross Struct validations.
+
+Installation
+============
+
+Use go get.
+
+ go get gopkg.in/bluesuncorp/validator.v5
+
+or to update
+
+ go get -u gopkg.in/bluesuncorp/validator.v5
+
+Then import the validator package into your own code.
+
+ import "gopkg.in/bluesuncorp/validator.v5"
+
+Usage and documentation
+=======================
+
+Please see http://godoc.org/gopkg.in/bluesuncorp/validator.v5 for detailed usage docs.
+
+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 brach 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.
+
+License
+=======
+Distributed under MIT License, please see license file in code for more details.

+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.
+
+Validate
+
+ validate := validator.New("validate", validator.BakedInValidators)
+
+ errs := validate.Struct(//your struct)
+ valErr := validate.Field(field, "omitempty,min=1,max=10")
+
+A simple example usage:
+
+ type UserDetail struct {
+ Details string `validate:"-"`
+ }
+
+ type User struct {
+ Name string `validate:"required,max=60"`
+ PreferedName string `validate:"omitempty,max=60"`
+ Sub UserDetail
+ }
+
+ user := &User {
+ Name: "",
+ }
+
+ // errs will contain a hierarchical list of errors
+ // using the StructErrors struct
+ // or nil if no errors exist
+ errs := validate.Struct(user)
+
+ // in this case 1 error Name is required
+ errs.Struct will be "User"
+ errs.StructErrors will be empty <-- fields that were structs
+ errs.Errors will have 1 error of type FieldError
+
+ NOTE: Anonymous Structs - they don't have names so expect the Struct name
+ within StructErrors to be blank.
+
+Error Handling
+
+The error can be used like so
+
+ fieldErr, _ := errs["Name"]
+ fieldErr.Field // "Name"
+ fieldErr.ErrorTag // "required"
+
+Both StructErrors and FieldError implement the Error interface but it's
+intended use is for development + debugging, not a production error message.
+
+ fieldErr.Error() // Field validation for "Name" failed on the "required" tag
+ errs.Error()
+ // Struct: User
+ // Field validation for "Name" failed on the "required" tag
+
+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, for us building an internationalized application
+I needed to know the field and what validation failed so that I could provide an error in the users specific language.
+
+ if fieldErr.Field == "Name" {
+ switch fieldErr.ErrorTag
+ case "required":
+ return "Translated string based on field + error"
+ default:
+ return "Translated string based on field"
+ }
+
+The hierarchical error structure is hard to work with sometimes.. Agreed Flatten function to the rescue!
+Flatten will return a map of FieldError's but the field name will be namespaced.
+
+ // if UserDetail Details field failed validation
+ Field will be "Sub.Details"
+
+ // for Name
+ Field will be "Name"
+
+Custom Functions
+
+Custom functions can be added
+
+ //Structure
+ func customFunc(top interface{}, current interface{}, field interface{}, param string) bool {
+
+ if whatever {
+ return false
+ }
+
+ return true
+ }
+
+ validate.AddFunction("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 implemented, for example Start & End Date range validation
+
+ // NOTE: when calling validate.Struct(val) val 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
+ //
+ // Because of the specific requirements and field names within each persons project that
+ // uses this library it is likely that custom functions will need to be created for your
+ // Cross Field Validation needs, however there are some build in Generic Cross Field validations,
+ // see Baked In Validators and Tags below
+
+ func isDateRangeValid(val interface{}, field interface{}, param string) bool {
+
+ myStruct := val.(myStructType)
+
+ if myStruct.Start.After(field.(time.Time)) {
+ return false
+ }
+
+ return true
+ }
+
+Multiple Validators
+
+Multiple validators on a field will process in the order defined
+
+ type Test struct {
+ Field `validate:"max=10,min=1"`
+ }
+
+ // max will be checked then min
+
+Bad Validator definitions are not handled by the library
+
+ type Test struct {
+ Field `validate:"min=10,max=0"`
+ }
+
+ // this definition of min max will never validate
+
+Baked In Validators and Tags
+
+NOTE: Baked In Cross field validation only compares fields on the same struct,
+if cross field + cross struct validation is needed your own custom validator
+should be implemented.
+
+NOTE2: 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
+
+Here is a list of the current built in validators:
+
+ -
+ Tells the validation to skip this struct field; this is particularily
+ handy in ignoring embedded structs from being validated. (Usage: -)
+
+ |
+ 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)
+
+ structonly
+ When a field that is a nest struct in encountered and contains this flag
+ any validation on the nested struct such as "required" 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.
+
+ omitempty
+ 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 with to dive will
+ require another dive tag. (Usage: dive)
+ Example: [][]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
+ Example2: [][]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
+ NOTE: in Example2 if the required validation failed, but all others passed
+ the hierarchy of FieldError's in the middle with have their IsPlaceHolder field
+ set to true. If a FieldError has IsSliceOrMap=true or IsMap=true then the
+ FieldError is a Slice or Map field and if IsPlaceHolder=true then contains errors
+ within its SliceOrArrayErrs or MapErrs fields.
+
+ required
+ This validates that the value is not the data types default value.
+ For numbers ensures value is not zero. For strings ensures value is
+ not "". For slices, arrays, and maps, ensures the length is not zero.
+ (Usage: required)
+
+ len
+ 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)
+
+ max
+ 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)
+
+ min
+ 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)
+
+ eq
+ 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)
+
+ ne
+ For strings & numbers, eq will ensure that the value is not
+ equal to the parameter given. For slices, arrays, and maps,
+ validates the number of items. (Usage: eq=10)
+
+ gt
+ 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. (Usage: gt=10)
+ For time.Time ensures the time value is greater than time.Now.UTC()
+ (Usage: gt)
+
+ gte
+ Same as 'min' above. Kept both to make terminology with 'len' easier
+ (Usage: gte=10)
+ For time.Time ensures the time value is greater than or equal to time.Now.UTC()
+ (Usage: gte)
+
+ lt
+ 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.
+ (Usage: lt=10)
+ For time.Time ensures the time value is less than time.Now.UTC()
+ (Usage: lt)
+
+ lte
+ Same as 'max' above. Kept both to make terminology with 'len' easier
+ (Usage: lte=10)
+ For time.Time ensures the time value is less than or equal to time.Now.UTC()
+ (Usage: lte)
+
+ eqfield
+ 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 password and confirm password:
+ Validation on Password field using validate.Struct Usage(eqfield=ConfirmPassword)
+ Validating by field validate.FieldWithValue(password, confirmpassword, "eqfield")
+
+ nefield
+ This will validate the field value against another fields value either within
+ a struct or passed in field.
+ usage examples are for ensuring two colors are not the same:
+ Validation on Color field using validate.Struct Usage(nefield=Color2)
+ Validating by field validate.FieldWithValue(color1, color2, "nefield")
+
+ gtfield
+ 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:
+ Validation on End field using validate.Struct Usage(gtfield=Start)
+ Validating by field validate.FieldWithValue(start, end, "gtfield")
+
+ gtefield
+ 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:
+ Validation on End field using validate.Struct Usage(gtefield=Start)
+ Validating by field validate.FieldWithValue(start, end, "gtefield")
+
+ ltfield
+ 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:
+ Validation on End field using validate.Struct Usage(ltfield=Start)
+ Validating by field validate.FieldWithValue(start, end, "ltfield")
+
+ ltefield
+ 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:
+ Validation on End field using validate.Struct Usage(ltefield=Start)

+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"`
