Composite
extends Constraint
in package
A constraint that is composed of other constraints.
You should never use the nested constraint instances anywhere else, because their groups are adapted when passed to the constructor of this class.
If you want to create your own composite constraint, extend this class and let return the name of the property which contains the nested constraints.

Methods
__construct()
Initializes the constraint with options.
public
__construct([mixed $options = null ][, array<string|int, mixed> $groups = null ][, mixed $payload = null ]) : mixed
The groups of the composite and its nested constraints are made consistent using the following strategy:
-
If groups are passed explicitly to the composite constraint, but not to the nested constraints, the options of the composite constraint are copied to the nested constraints;
-
If groups are passed explicitly to the nested constraints, but not to the composite constraint, the groups of all nested constraints are merged and used as groups for the composite constraint;
-
If groups are passed explicitly to both the composite and its nested constraints, the groups of the nested constraints must be a subset of the groups of the composite constraint. If not, a is thrown.
All this is done in the constructor, because constraints can then be cached. When constraints are loaded from the cache, no more group checks need to be done.
Parameters
- $options : mixed = null
-
The options (as associative array) or the value for the default option (any other type)
- $groups : array<string|int, mixed> = null
-
An array of validation groups
- $payload : mixed = null
-
Domain-specific data attached to a constraint
__get()
Returns the value of a lazily initialized option.
public
__get(string $option) : mixed
Corresponding properties are added to the object on first access. Hence this method will be called at most once per constraint instance and option name.
Parameters
- $option : string
Tags
__isset()
public
__isset(string $option) : bool
Parameters
- $option : string
Return values
bool__set()
Sets the value of a lazily initialized option.
public
__set(string $option, mixed $value) : mixed
Corresponding properties are added to the object on first access. Hence this method will be called at most once per constraint instance and option name.
Parameters
- $option : string
- $value : mixed
Tags
addImplicitGroupName()
Adds the given group if this constraint is in the Default group.
public
addImplicitGroupName(string $group) : mixed
Implicit group names are forwarded to nested constraints.
Parameters
- $group : string
getDefaultOption()
Returns the name of the default option.
public
getDefaultOption() : string|null
Override this method to define a default option.
Tags
Return values
string|nullgetErrorName()
Returns the name of the given error code.
public
static getErrorName(string $errorCode) : string
Parameters
- $errorCode : string
Tags
Return values
stringgetRequiredOptions()
Returns the name of the required options.
public
getRequiredOptions() : array<string|int, string>
Override this method if you want to define required options.
Tags
Return values
array<string|int, string>getTargets()
Returns whether the constraint can be put onto classes, properties or both.
public
getTargets() : string|array<string|int, string>
This method should return one or more of the constants Constraint::CLASS_CONSTRAINT and Constraint::PROPERTY_CONSTRAINT.
Return values
string|array<string|int, string> —One or more constant values
validatedBy()
Returns the name of the class that validates this constraint.
public
validatedBy() : string
By default, this is the fully qualified name of the constraint class suffixed with "Validator". You can override this method to change that behavior.
Return values
stringgetCompositeOption()
Returns the name of the property that contains the nested constraints.
protected
abstract getCompositeOption() : string
Return values
stringinitializeNestedConstraints()
Initializes the nested constraints.
protected
initializeNestedConstraints() : mixed
This method can be overwritten in subclasses to clean up the nested constraints passed to the constructor.
