How to insert json string into smarty template?

Question

I prepare json string in php file

$groups_json = json_encode($groups);
$smarty->assign('groups', $groups_json);

How can I put it properly into in .tpl file like that

<script>
var groups = "{$groups}"; // <-- here

I have smarty 3

Answer 1

My issue was that smarty converted quotes and other stuff to html entities. The answer is to add nofilter parameter to the template variable

var groups = {$groups nofilter};
