我的语法有问题。我不知道如何完成以下内容。我建立了一个会员系统，允许观众注册并登录并查看我的网站。我想制作一个评论系统，这样人们可以评论一些东西。我建立了一个测试评论系统，它似乎运行良好，没有用户信息。但是，如果我尝试为我的用户系统创建一个页面，并包含我的评论系统，则会由于语法错误而崩溃。我不是说喜欢不会共存，他们是，但与其他东西冲突并发表评论不包括从MySQL数据库检索到的用户信息，我不能定义行列，以便用户可以编辑他/她的帖子或删除他们的帖子，而不修改其他帖子，管理员应该能够做到这一切。我不知道出了什么问题或如何解决问题。我准备好以您的方式发送信息，但我不知道您可能需要什么，所以如果您要求，我会发布您需要的任何内容。上述PHP评论系统已堕落

没有任何错误，它只是不会出现..这另行制定之前，我试着实现我的用户系统，现在我无法将它移到用户可以编辑或删除他的帖子的位置，而管理员可以完成这一切。

你能提供一些代码，以便有人可以发现你的语法错误吗？ – ppp 2012-02-17 22:12:42
复制您收到的错误并将其粘贴到此处。还包括错误中提到的代码行（和周围行）（它会在错误消息中给出行号）。 – webbiedave 2012-02-17 22:14:34
