Support for 'when:' and nesting inside kirby builder(?) about kirby-imageradio

Having the same issue with using it in Kirby Builder.

The issue is caused by an exception that occurs in the 'ratio' prop function:

kirby-imageradio/lib/fields/imageradio.php

Lines 24 to 35 in 855b7a4

	'ratio' => function($ratio = '1/1') {
	$computed = 1;
	if (preg_match('/(\d+)(?:\s*)([\/])(?:\s*)(\d+)/', $ratio, $matches) !== false){
	$computed = $matches[3] / $matches[1];
	}
	$computed = $computed * 100;
	$ratio = round($computed, 3, PHP_ROUND_HALF_DOWN);
	return $ratio;
	},

The 'ratio' function is being called multiple times. The first time, it gets the proper ratio value as a parameter. Subsequent times, it is called with its latest return value as the parameter. I.e. first it gets called with "1/2", then it gets called again with 200, causing an exception on line 28.

It seems like the calling code (I suppose Kirby Builder) is messing up by calling the prop function again with its own return value.

This a temporary fix I applied locally:

function ($ratio = '1/1') {
            if (is_numeric($ratio)) {
                return $ratio;
            }
// ...
}

When the function gets called again with its computed numeric value, I'm returning that value.

Hello,

Thanks for the kind words!

I don't have any issue with the when: attribute with 3.2, have you given it a shot? I'll close this for more clarity in my tickets, feel free to reopen if the problem is still here.

As for the Builder issue, the field should behave properly even when hidden. It seems that the issue is on the Builder's side, you should rather open an issue there. Thank you for the investigation @bertwillekens, and the workaround. I won't add it in the field since there shouldn't be a need for it at all, but it can be of use if Tim doesn't have time to look into it in the near future.
