ConstraintViolation

__construct(string $message, string $messageTemplate, array $parameters, mixed $root, string $propertyPath, mixed $invalidValue, int|null $plural = null, mixed $code = null, Constraint $constraint = null, mixed $cause = null)

Creates a new constraint violation.

Parameters

string	$message	The violation message
string	$messageTemplate	The raw violation message
array	$parameters	The parameters to substitute in the raw violation message
mixed	$root	The value originally passed to the validator
string	$propertyPath	The property path from the root value to the invalid value
mixed	$invalidValue	The invalid value that caused this violation
int|null	$plural	The number for determining the plural form when translating the message
mixed	$code	The error code of the violation
Constraint	$constraint	The constraint whose validation caused the violation
mixed	$cause	The cause of the violation

string __toString()

Converts the violation into a string for debugging purposes.

Return Value

string

The violation as string

string getMessageTemplate()

Returns the raw violation message.

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

Return Value

string

The raw violation message

array getParameters()

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

int|null getPlural()

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

int|null

The number to use to pluralize of the message

string getMessage()

Returns the violation message.

Return Value

string

The violation message

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.

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".

mixed getInvalidValue()

Returns the value that caused the violation.

Return Value

mixed

the invalid value that caused the validated constraint to fail

Constraint|null getConstraint()

Returns the constraint whose validation caused the violation.

Return Value

Constraint|null

The constraint or null if it is not known

mixed getCause()

Returns the cause of the violation.

Return Value

mixed

string|null getCode()

Returns a machine-digestible error code for the violation.

Return Value

string|null

The error code
