OptionsProviderInterface

interface OptionsProviderInterface (View source)

Interface for retrieving all possible and settable values.

While possible values specify which values existing data might have, settable values define the values that are allowed to be set by a user.

For example, in a workflow scenario, the settable values for a state field might depend on the currently set state, while possible values are all states. Thus settable values would be used in an editing context, while possible values would be used for presenting filtering options in a search.

For convenience, lists of both settable and possible values are also provided as structured options arrays that can be used in an Options widget such as a select box or checkboxes.

Note that this interface is mostly applicable for primitive data values, but can be used on complex data structures if a (primitive) main property is specified. In that case, the allowed values and options apply to the main property only.

Methods

array
getPossibleValues(AccountInterface $account = NULL)

Returns an array of possible values.

array
getPossibleOptions(AccountInterface $account = NULL)

Returns an array of possible values with labels for display.

array
getSettableValues(AccountInterface $account = NULL)

Returns an array of settable values.

array
getSettableOptions(AccountInterface $account = NULL)

Returns an array of settable values with labels for display.

Details

at line 44
array getPossibleValues(AccountInterface $account = NULL)

Returns an array of possible values.

If the optional $account parameter is passed, then the array is filtered to values viewable by the account.

Parameters

AccountInterface $account

(optional) The user account for which to filter the possible values. If omitted, all possible values are returned.

Return Value

array

An array of possible values.

at line 63
array getPossibleOptions(AccountInterface $account = NULL)

Returns an array of possible values with labels for display.

If the optional $account parameter is passed, then the array is filtered to values viewable by the account.

Parameters

AccountInterface $account

(optional) The user account for which to filter the possible options. If omitted, all possible options are returned.

Return Value

array

An array of possible options for the object that may be used in an Options widget, for example when existing data should be filtered. It may either be a flat array of option labels keyed by values, or a two-dimensional array of option groups (array of flat option arrays, keyed by option group label). Note that labels should NOT be sanitized.

at line 78
array getSettableValues(AccountInterface $account = NULL)

Returns an array of settable values.

If the optional $account parameter is passed, then the array is filtered to values settable by the account.

Parameters

AccountInterface $account

(optional) The user account for which to filter the settable values. If omitted, all settable values are returned.

Return Value

array

An array of settable values.

at line 97
array getSettableOptions(AccountInterface $account = NULL)

Returns an array of settable values with labels for display.

If the optional $account parameter is passed, then the array is filtered to values settable by the account.

Parameters

AccountInterface $account

(optional) The user account for which to filter the settable options. If omitted, all settable options are returned.

Return Value

array

An array of settable options for the object that may be used in an Options widget, usually when new data should be entered. It may either be a flat array of option labels keyed by values, or a two-dimensional array of option groups (array of flat option arrays, keyed by option group label). Note that labels should NOT be sanitized.
