애드센스 필터 애드온을 수정중입니다, 댓글 내용은 어떻게 불러오나요?

if($called_position == 'before_display_content' && $addon_info->load_admin = 'N')
{
    
    $swc = false;
    $dmt = Context::get('oDocument');
    $cmt = Context::get('oComment');

// 문서 내용에 금지 단어가 있다면 애드센스를 삭제
if($addon_info->denied_content == 'Y'){
        $block_words = explode(',',$addon_info->denied_word_content);
        $count_block_words = count($block_words);
        foreach($block_words as $value) {
            if(strpos($dmt->variables['content'],$value) !== false) {
                $swc = true;
                return;
            } else if(strpos($dmt->variables['title'],$value) !== false) {
                $swc = true;
                return;
            } else if(strpos($cmt->variables['content'],$value) !== false) {
                $swc = true;
                return;
            }
// 문서 내용에 금지 단어가 없다면 애드센스를 출력
} if($swc == false) {
$footer = sprintf('<script async src="//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>');
Context::addHtmlFooter($footer);
return;
}
