XF 2.2 Limit and shuffle finder results

[Orit]

Hi
I have a finder for some categories and I want to shuffle the results and limit them.
Since I don't want to always return the first x of the results, I am not limiting in the finder itself.

My code is as follows:

$categoryFinder = $this->finder('****')
    ->where('category_id', $categoryIds);

$categories = $categoryFinder->fetch();
$categories = $categories->shuffle();

$categories = $categories->slice(0, $limit);

I am wondering if there is a better (built in maybe?) way to do so?
(I did not find a way to do so through the template. Is there a way to limit results in a for loop inside the template?)

Thanks!

Have you tried to incorporate the template rand statement instead of PHP shuffle?

I have a number of background images that I'd like to randomly select from. Is there a way to output a random number between certain values using template syntax?

I don't think rand will work in this case.

The shuffle function randomises every element in the array, preserving the array content, whereas the rand function just spits out a random number between 2 values.
