# KeySet
|
|
|
|
- `KeySet(Validator $validator)`
|
|
- `KeySet(Validator $validator, Validator ...$validators)`
|
|
|
|
Validates a keys in a defined structure.
|
|
|
|
```php
|
|
v::keySet(v::key('foo', v::intVal()))->assert(['foo' => 42]);
|
|
// Validation passes successfully
|
|
|
|
v::keySet(
|
|
v::keyExists('foo'),
|
|
v::keyExists('bar')
|
|
)->assert(['foo' => 'whatever', 'bar' => 'something']);
|
|
// Validation passes successfully
|
|
```
|
|
|
|
It will validate the keys in the array with the validators passed in the constructor.
|
|
|
|
```php
|
|
v::keySet(
|
|
v::key('foo', v::intVal())
|
|
)->assert(['foo' => 'string']);
|
|
// → `.foo` must be an integer
|
|
```
|
|
|
|
Extra keys are not allowed:
|
|
|
|
```php
|
|
v::keySet(
|
|
v::key('foo', v::intVal())
|
|
)->assert(['foo' => 42, 'bar' => 'String']);
|
|
// → `.bar` must not be present
|
|
```
|
|
|
|
Missing required keys are not allowed:
|
|
|
|
```php
|
|
v::keySet(
|
|
v::key('foo', v::intVal()),
|
|
v::key('bar', v::stringType()),
|
|
v::key('baz', v::boolType())
|
|
)->assert(['foo' => 42, 'bar' => 'String']);
|
|
// → `.baz` must be present
|
|
```
|
|
|
|
Missing non-required keys are allowed:
|
|
|
|
```php
|
|
v::keySet(
|
|
v::key('foo', v::intVal()),
|
|
v::key('bar', v::stringType()),
|
|
v::keyOptional('baz', v::boolType())
|
|
)->assert(['foo' => 42, 'bar' => 'String']);
|
|
// Validation passes successfully
|
|
```
|
|
|
|
Alternatively, you can pass a chain of key-related validators to `keySet()`:
|
|
|
|
```php
|
|
v::keySet(
|
|
v::init()
|
|
->key('foo', v::intVal())
|
|
->key('bar', v::stringType())
|
|
->keyOptional('baz', v::boolType())
|
|
)->assert(['foo' => 42, 'bar' => 'String']);
|
|
// Validation passes successfully
|
|
```
|
|
|
|
It is not possible to negate `keySet()` validators with `not()`.
|
|
|
|
The keys' order is not considered in the validation.
