[TYPO3-mvc] FLUID :: how can you access properties of m:n related objects?

[Henjo Hoeksma]

Hi Roland,

you can use an iterator for this

<f:for each="{produkts}" as="produkt" iteration="produktIterator">
<f:if condition="{produktIterator.isFirst}">
...

See the Fluid Viewhelper for if on the possibilities you have.

Kind regards,

Henjo

Problems are small because we learned how to deal with them.
