Variable: Get

ViewHelper used to read the value of a current template variable. Can be used with dynamic indices in arrays:

<v:variable.get name="array.{dynamicIndex}" />
<v:variable.get name="array.{v:variable.get(name: 'arrayOfSelectedKeys.{indexInArray}')}" />
<f:for each="{v:variable.get(name: 'object.arrayProperty.{dynamicIndex}')}" as="nestedObject">
    ...
</f:for>

Or to read names of variables which contain dynamic parts:

<!-- if {variableName} is "Name", outputs value of {dynamicName} -->
{v:variable.get(name: 'dynamic{variableName}')}

If your target object is an array with unsequential yet numeric indices (e.g. {123: 'value1', 513: 'value2'}, commonly seen in reindexed UID map arrays) use useRawIndex="TRUE" to indicate you do not want your array/QueryResult/Iterator to be accessed by locating the Nth element - which is the default behavior.

Do not try `useRawKeys="TRUE"` on QueryResult or
ObjectStorage unless you are fully aware what you are
doing. These particular types require an unpredictable
index value - the SPL object hash value - when accessing
members directly. This SPL indexing and the very common
occurrences of QueryResult and ObjectStorage variables
in templates is the very reason why `useRawKeys` by
default is set to `FALSE`.
