[Flow] [Fluid] How can I use dynamic array indexes in templates?

[Pavlina]

Hi all!

I am new in Typo3 Flow and I am currently developing my first project with it. I use Typo3 Flow 2.0 beta 1.

I understood from this post:

http://forge.typo3.org/projects/typo3v4-mvc/wiki/FAQ#How-can-I-use-dynamic-array-indexes

that it's not possible to use dynamic array indexes in templates. But I need it very much. I have an array of arrays - items, grouped by week day - and I need to dynamically access each sub-array trough a weekDay variable and iterate it with the foreach view helper.

I have found this code:

https://gist.github.com/afoeder/2406841

and I used it to write a custom view helper. My idea was to get each sub-array dynamically and pass it to the foreach view helper like this:

<f:for each="<my:arrayAccess array={tasksGroupByWeekDay} key={weekDay} />" as="task">

or

<f:for each="{my:arrayAccess(array: tasksGroupByWeekDay, key: weekDay)}" as="task">

But the custom view helper does not pass the array to the foreach view helper, it directly renders it in the template, which is obviously not what I heed. I couldn't find a way to write a view helper, which returns a value without render it in the template.

Any help or suggestion which is the correct way to achieve my goal will be highly appreciated!

Thank you in advance,
Pavlina
