PHP Class FluidTYPO3\Vhs\ViewHelpers\Iterator\ColumnViewHelper
Implementation of
array_column for Fluid.
Accepts an input iterator/array and creates a new array
using values from one column and optionally keys from another
column.
#### Usage examples
xml
User {username} has UID {uid}.
The above demonstrates the logic of the ViewHelper, but the
example itself of course gives the same result as just iterating
the
users variable itself and outputting
{user.username} etc.,
but the real power of the ViewHelper comes when using it to feed
other ViewHelpers with data sets:
xml
Select user:
xml
All UIDs: {users -> v:iterator.column(columnKey: 'uid') -> v:iterator.implode()}
xml
Our users live in the following countries:
{users -> v:iterator.column(columnKey: 'countryName')
-> v:iterator.unique()
-> v:iterator.implode(glue: ' - ')}
Note that the ViewHelper also supports the "as" argument which
allows you to not return the new array but instead assign it
as a new template variable - like any other "as"-capable ViewHelper.
#### Caveat
This ViewHelper passes the subject directly to
array_column and
as such it *does not support dotted paths in either key argument
to extract sub-properties*. That means it *does not support Extbase
enties as input unless you explicitly implemented
ArrayAccess on
the model of the entity and even then support is limited to first
level properties' values without dots in their names*.
