interface ConstraintViolationInterface

A violation of a constraint that happened during validation.

For each constraint that fails during validation one or more violations are created. The violations store the violation message, the path to the failing element in the validation graph and the root element that was originally passed to the validator. For example, take the following graph:

(Person)---(firstName: string)
     \
  (address: Address)---(street: string)

If the Person object is validated and validation fails for the "firstName" property, the generated violation has the Person instance as root and the property path "firstName". If validation fails for the "street" property of the related Address instance, the root element is still the person, but the property path is "address.street".

Methods

string
getMessage()

Returns the violation message.

string
getMessageTemplate()

Returns the raw violation message.

array
getMessageParameters()

Returns the parameters to be inserted into the raw violation message.

integer|null
getMessagePluralization()

Returns a number for pluralizing the violation message.

mixed
getRoot()

Returns the root element of the validation.

string
getPropertyPath()

Returns the property path from the root element to the violation.

mixed
getInvalidValue()

Returns the value that caused the violation.

mixed
getCode()

Returns a machine-digestible error code for the violation.

Details

at line line 47
string getMessage()

Returns the violation message.

Return Value

string The violation message.

at line line 60
string getMessageTemplate()

Returns the raw violation message.

The raw violation message contains placeholders for the parameters returned by {@link getMessageParameters}. Typically you'll pass the message template and parameters to a translation engine.

Return Value

string The raw violation message.

at line line 72
array getMessageParameters()

Returns the parameters to be inserted into the raw violation message.

Return Value

array A possibly empty list of parameters indexed by the names that appear in the message template.

getMessageTemplate

at line line 90
integer|null getMessagePluralization()

Returns a number for pluralizing the violation message.

For example, the message template could have different translation based on a parameter "choices":

  • Please select exactly one entry. (choices=1)
  • Please select two entries. (choices=2)

This method returns the value of the parameter for choosing the right pluralization form (in this case "choices").

Return Value

integer|null The number to use to pluralize of the message.

at line line 102
mixed getRoot()

Returns the root element of the validation.

Return Value

mixed The value that was passed originally to the validator when the validation was started. Because the validator traverses the object graph, the value at which the violation occurs is not necessarily the value that was originally validated.

at line line 118
string getPropertyPath()

Returns the property path from the root element to the violation.

Return Value

string The property path indicates how the validator reached the invalid value from the root element. If the root element is a Person instance with a property "address" that contains an Address instance with an invalid property "street", the generated property path is "address.street". Property access is denoted by dots, while array access is denoted by square brackets, for example "addresses[1].street".

at line line 128
mixed getInvalidValue()

Returns the value that caused the violation.

Return Value

mixed The invalid value that caused the validated constraint to fail.

at line line 135
mixed getCode()

Returns a machine-digestible error code for the violation.

Return Value

mixed The error code.
