Hello, I've finished a plugin but there's a bug. I know where code is wrong but I can't fix it:

function news_show(){
    global $db, $news, $news_list, $news_content;
    $l_news = $db->write_query("SELECT * FROM ".TABLE_PREFIX."news ORDER BY id DESC");
    if($db->num_rows($l_news) > 0){
        $news_content = "Non ci sono news da mostrare";
    } else {
        while($row = $db->fetch_array($l_news)){
            $news_content .= $row['text'];
        }    
    }
    
    eval('$news_list = "'.$templates->get("news_list").'";');
    eval('$news = "'.$templates->get("news").'";');
}

Templates

    <div class="msg">
        <ul>
            {$news_list}
