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

The choices are returned with the same keys and in the same order as the corresponding values in the given array.
