Details
__construct(ChoiceListInterface $adaptedList)
Adapts a legacy choice list to {@link ChoiceListInterface}.
Parameters
ChoiceListInterface | $adaptedList | The adapted list |
array getChoices()
Returns all selectable choices.
Return Value
array | The selectable choices indexed by the corresponding values |
string[] getValues()
Returns the values for the choices.
The values are strings that do not contain duplicates.
Return Value
string[] | The choice values |
string[] getStructuredValues()
Returns the values in the structure originally passed to the list.
Contrary to {@link getValues()}, the result is indexed by the original keys of the choices. If the original array contained nested arrays, these nested arrays are represented here as well:
$form->add('field', 'choice', array(
'choices' => array(
'Decided' => array('Yes' => true, 'No' => false),
'Undecided' => array('Maybe' => null),
),
));
In this example, the result of this method is:
array(
'Decided' => array('Yes' => '0', 'No' => '1'),
'Undecided' => array('Maybe' => '2'),
)
Return Value
string[] | The choice values |
int[]|string[] getOriginalKeys()
Returns the original keys of the choices.
The original keys are the keys of the choice array that was passed in the "choice" option of the choice type. Note that this array may contain duplicates if the "choice" option contained choice groups:
$form->add('field', 'choice', array(
'choices' => array(
'Decided' => array(true, false),
'Undecided' => array(null),
),
));
In this example, the original key 0 appears twice, once for true
and once for null
.
Return Value
int[]|string[] | The original choice keys indexed by the corresponding choice values |
array getChoicesForValues(array $values)
Returns the choices corresponding to the given values.
The choices are returned with the same keys and in the same order as the corresponding values in the given array.
Parameters

Return Value
array | An array of choices |
string[] getValuesForChoices(array $choices)
Returns the values corresponding to the given choices.
The values are returned with the same keys and in the same order as the corresponding choices in the given array.
Parameters
array | $choices | An array of choices. Non-existing choices in this array are ignored |
Return Value
string[] | An array of choice values |
ChoiceListInterface getAdaptedList()
Returns the adapted choice list.
Return Value
ChoiceListInterface | The adapted list |
