Available Constraints

Below are all the currently supported constraints. If you need more you can create your own Custom validators as well.
propertyName = {
        // The field under validation must be yes, on, 1, or true. This is useful for validating "Terms of Service" acceptance.
        accepted : any value,
​
        // The field must be alphanumeric ONLY
        alpha : any value,
​
        // discrete math modifiers
        discrete : (gt,gte,lt,lte,eq,neq):value
​
        // value in list
        inList : list,
​
        // max value
        max : value,
​
        // Validation method to use in the target object must return boolean accept the incoming value and target object 
        method : methodName,
​
        // min value
        min : value,
​
        // range is a range of values the property value should exist in
        range : eg: 1..10 or 5..-5,
​
        // regex validation
        regex : valid no case regex
​
        // required field or not, includes null values
        required : boolean [false],
​
        // The field under validation must be present and not empty if the `anotherfield` field is equal to the passed `value`.
        requiredIf : {
            anotherfield:value, anotherfield:value
        }
​
        // The field under validation must be present and not empty unless the `anotherfield` field is equal to the passed 
        requiredUnless : {
            anotherfield:value, anotherfield:value
        }
​
        // same as but with no case
        sameAsNoCase : propertyName
​
        // same as another property
        sameAs : propertyName
​
        // size or length of the value which can be a (struct,string,array,query)
        size  : numeric or range, eg: 10 or 6..8
​
        // specific type constraint, one in the list.
        type  : (alpha,array,binary,boolean,component,creditcard,date,email,eurodate,float,GUID,integer,ipaddress,json,numeric,query,ssn,string,struct,telephone,url,usdate,UUID,xml,zipcode),
​
        // UDF to use for validation, must return boolean accept the incoming value and target object, validate(value,target):boolean
        udf = variables.UDF or this.UDF or a closure.
​
        // Check if a column is unique in the database
        unique = {
            table : The table name,
            column : The column to check, defaults to the property field in check
        }
​
        // Custom validator, must implement coldbox.system.validation.validators.IValidator
        validator : path or wirebox id, example: 'mypath.MyValidator' or 'id:MyValidator'
}
accepted
The field must be yes, on, 1, or true. This is useful for validating "Terms of Service" acceptance.
terms = { accepted = true }
alpha
The field must be alphabetical ONLY
terms = { alpha = true }
discrete
The field must pass certain discrete math operations using the format: operator:value
gt - Greater than the value
gte - Greater than or equal to the value
lt - Less than the value
lte - Less than or equal to the value
eq - Equal to the value
neq - Not equal to the value
myField = { discrete = "gt:4" }
myField = { discrete = "eq:luis" }
myField = { discrete = "lte:1" }
inList
The field must be in the included list
myField = { inList = "red,green,blue" }
max
The field must be less than or equal to the defined value
myField = { max = 25 }
method
The methodName will be called on the target object and it will pass in validationData and targetValue. It must return a boolean response: true = pass, false = fail.
myField = { method = "methodName" }
​
function methodName( validationData, targetValue ){
    return true;
}
min
The field must be greater than or equal to the defined value
myField = { min = 8 }
range
The field must be within the range values and the validation data must follow the range pattern: min..max
myField = { range = "1..5" }
myField = { range = "5..-5" }
regex
The field must pass the regular expression match with no case sensitivity
myField = { regex = "^(sick|vacation|disability)$" }
required
The field must have some type of value and not null.
myField = { required=true }
myField = { required=false }
requiredIf
the field under validation must be present and not empty if the anotherfield field is equal to the passed value.
myField = { 
 requiredIf = {
  field2 = "test",
  field3 = "hello"
 }
}
requiredUnless
The field under validation must be present and not empty unless the anotherfield field is equal to the passed
myField = { 
 requiredUnless = {
  field2 = "test",
  field3 = "hello"
 }
}
sameAsNoCase
The field must be the same as another field with no case sensitivity
myField = { sameAs = "otherField" }
sameAs
The field must be the same as another field with case sensitivity
myField = { sameAs = "otherField" }
size
The field value size must be within the range values and the validation data must follow the range pattern: min..max. Value can be a (struct,string,array,query)
myField = { size : 10 }
myFiedl = { size : "8..20" }
type
One of the most versatile validators. It can test if the value is of the following specific types:
alpha
array
binary
boolean
component
creditcard
date
email
eurodate
float
GUID
integer
ipaddress
json
numeric
query
ssn
string
struct
telephone
url
usdate
UUID
xml
zipcode
myField = { type : "float" }
udf
The field value will be passed to the declared closure/lambda to use for validation, must return boolean accept the incoming value and target object, validate(value,target):boolean
myField = { udf = function( value, target ) { return true; } }
myField = { udf = (value,target) => true }
unique
The field must be a unique value in a specific database table. The validation data is a struct with the following keys:
table : The name of the table to check
column : The column to check, defaults to the property field in check 
myField = { unique = { table : "users", column : "username" } }
validator
The field value will be passed to the validator CFC to be used for validation. Please see Custom Validators​
myField = { validator = "[email protected]" }
