Image random

[Frank Vèssia]

i'm getting this strange behaviour with image getRandom

I want to display all images of one field randomly.

So i first count my total images and than use getRandom.

<?php

$tot = count($gallery->images); 

$gallery = $gallery->images->getRandom($tot);

foreach ($gallery as $image){
...
}

I always get the same order but if i change the $tot variable with a smaller value (smaller than the total count) it works...

You could use shuffle method instead.

Sorry for short posts (mobile). Shuffle ia documented here: http://processwire.com/api/arrays/

Thanks Apeisa. It works fine...i didn't know about the shuffle method.

The behavior of PHP's array_rand() function (used by getRandom) does seem a little strange when pulling the entire array. I agree with Apeisa that shuffle() is a better way to go for randomizing the entire thing, whereas getRandom is better for pulling 1 or a few elements.
