Актуально для версии 2.9.6

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, $template = 'default') {
list($sTemplateBlock, $sTemplateLine, $template_add_user, $template_add_guest, $template_smiles) = def_module::loadTemplates('tpls/comments/'.$template.'.tpl', 'comments_list_block', 'comments_list_line', "comments_block_add_user", "comments_block_add_guest", "smiles");

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: 

<?php
$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:
