Using getRandom(x)

[Jim Yost]

Hi,

I am trying to return 3 random images from an image field using getRandom(3). It appears to be returning all 6 results. I do have only 6 images uploaded to the field.

<?php
$images = $page->images->getRandom(3);
foreach($images as $image)
{
    $thumbnail = $image->size(118,112);
    echo "<a href='{$image->url}'><img class='photo' src='{$thumbnail->url}' alt='{$image->description}' /></a>";
}

I initially thought it was a problem with WireArray, however the following works as expected.

<?php
$test_pages = $pages->get("/")->children->getRandom(3);
foreach($test_pages as $test) {
    echo $test->name . "<br />";
}

Any ideas?

-Jim

Hi Jim,

You found a bug! It was in the Pagefiles class in the makeNew() function, which was returning a populated list when it should be been returning a blank one. I have fixed it in the latest commit. Thanks for finding this.
