PHP Класс FluidTYPO3\Vhs\ViewHelpers\Iterator\UniqueViewHelper
Implementation of
array_unique for Fluid
Accepts an input array of values and returns/assigns
a new array containing only the unique values found
in the input array.
Note that the ViewHelper does not support the sorting
parameter - if you wish to sort the result you should
use
v:iterator.sort in a chain.
#### Usage examples
xml
Countries of our users: {userCountries -> v:iterator.unique() -> v:iterator.implode(glue: ' - ')}
Output:
xml
Countries of our users: USA - USA - Denmark - Germany - Germany - USA - Denmark - Germany
xml
Countries of our users, in alphabetical order:
{userCountries -> v:iterator.unique()
-> v:iterator.sort(sortFlags: 'SORT_NATURAL')
-> v:iterator.implode(glue: ' - ')}
Output:
xml
Countries of our users: Denmark - Germany - USA
