// 检查用户是否登录
if (empty($cfg_ml->fields['userid'])) {

<form action="submit.php" method="post">
    <input type="hidden" name="action" value="submit_article">
    <input type="text" name="title" placeholder="文章标题">
    <textarea name="content" placeholder="文章内容"></textarea>
    <input type="submit" value="提交">
</form>

if ($action == 'submit_article') {
    global $dsql;
    $title = $_POST['title'];
    $content = $_POST['content'];
    $userid = $cfg_ml->fields['userid'];

    // 插入数据到数据库
    $sql = "INSERT INTO `dede_archives` (typeid, title, content, mid, redirecturl, userip, dtime) VALUES (2, '$title', '$content', $userid, '', '', NOW())";
    $dsql->ExecuteNoneQuery($sql);

    showMsg('投稿成功', 'index.php');

if (!$dsql->ExecuteNoneQuery($sql)) {
    showMsg('投稿失败，请稍后再试', 'submit.php');
