Strange snippet call

I’m refactoring a site I didn’t build in the first place and i’ve hit a bit im not familiar with and i need to change it slightly… i don’t really understand it, despite reading the docs for r().

I have a snippet call like this:

<?php snippet('common/blog-disqus', ['disqus_shortname'=>'myshortname', 'disqus_developer' => r(c::get('live')== true, true, false)], true)?>

But it doesn’t seem to work. My live variable in the config is either true or false, whereas the old site this was set to a string. I think that stops disqus showing up at all on a dev environment. If i change the very last true right on the end to false, disqus loads on dev, so i know the snippet loads ok. I just need to fix it so it respects the config variable setting.

How do i make it work with a true or false?

First of all, the last truedoesn’t make sense, unless the snippet is stored in a variable.

$snippet = snippet('xy', [], true);

otherwise

<?php snippet('xy', []); ?>

As regards the rest, I’d need more context as to what is inside the snippet.

The snippet is pretty much just a standard Disqus include, with some things filled in from variables and Kirby…

<?php
// set the defaults
if(!isset($disqus_shortname))  die('Please pass the disqus shortname');
if(!isset($disqus_title))      $disqus_title = str_replace("'",'’', $page->title());
if(!isset($disqus_developer))  $disqus_developer = false;
if(!isset($disqus_identifier)) $disqus_identifier = $page->uri();
if(!isset($disqus_url))        $disqus_url = $page->url();

$disqus_title     = addcslashes($disqus_title, "'");
$disqus_developer = ($disqus_developer) ? 'true' : 'false';

?>
<div id="disqus_thread"></div>
<script type="text/javascript">
  var disqus_shortname  = '<?= $disqus_shortname ?>'; // required: replace example with your forum shortname
  var disqus_title      = '<?= html($disqus_title) ?>';
  var disqus_developer  = '<?= $disqus_developer ?>'; // developer mode
  var disqus_identifier = '<?= $disqus_identifier ?>';
  var disqus_url        = '<?= $disqus_url ?>';

  (function() {
    var dsq = document.createElement('script'); dsq.type = 'text/javascript'; dsq.async = true;
    dsq.src = 'https://' + disqus_shortname + '.disqus.com/embed.js';
    (document.getElementsByTagName('head')[0] || document.getElementsByTagName('body')[0]).appendChild(dsq);
  })();
</script>

The original snippet call was like this:

snippet('disqus', ['disqus_shortname'=>'myshortname', 'disqus_developer' => r(c::get('env')=='dev', true, false)], true);

I solved it another way. Seems that embed code for Disqus is quite old and the current version can detect localhost and not load itself accordingly. I have upgraded the embed code.
