Вложенные комментарии

В модуле Блоги 2.0. есть возможность оставлять комментарии к комментарию. В этой статье будет представлен пример кастомного макроса, который позволяет использовать практически идентичную функциональность в модуле "Комментарии". Пропишем необходимый код в файле /classes/modules/comments/__custom.php, после слов "//TODO: Write here your own macroses":

public function commentsList($postId = false, $template = 'default') {

Создадим в той же папке файл permissions.custom.php с кратким содержанием:

<?php
$permissions = Array('insert' => Array('commentsList'));
?>

Изменим tpl шаблон /tpls/comments/default.tpl:

$FORMS = Array();

$FORMS['comments_list_block'] = <<<END
<script language="javascript">
<!--
function setCommentParent(parentId) {
var form   = document.getElementById('comment_add_form');
var editor = document.getElementById('message');
if(form)
form.action = '/comments/post/' + parentId + '/';
if(editor)
editor.focus();
}
-->
</script>

Макрос commentsList вызывается следующим образом:
