[TYPO3-mvc] How do you get the "next" record when on a detail view?

[Claus Due]

Hi Stephen,

I have a suggestion. If what you are trying to do is to make some sort of navigation (almost page browser but with one item per page and only previous/next links) then this might be useful:

http://fedext.net/fed-viewhelpers/loops-conditions/next/
http://fedext.net/fed-viewhelpers/loops-conditions/previous/

What you would need to do is to always assign the "master list" of Cards (for example a $repository->findAll() which is always in the same order), then use that template variable as the "haystack" parameter and the currently viewed card as the "needle" parameter.

This way you can link to the next Card in your result set:

<f:link action="show" arguments="{card: '{fed:next(haystack: allCards, needle: card)}'">Next card</f:link>

The same exact thing goes for the fed:previous viewhelper.

Hope this helps :)
