Hi,
This is a content tag. The content plugin which will replace the tag by the actual module is only triggered when Joomla displays content. So if you want it to be replaced, you need to tell Joomla that it is in a content.
For example, like this:
<?php echo JHTML::_('content.prepare', '{loadmoduleid 132}'); ?>
Otherwise, if you want to be able to add modules anywhere on your website with tags without having to use PHP to make them as "content", you need to use the plugin Modules Anywhere:
