我现在需要做的是在我的索引中添加一个按钮，如果他们点击它，它应该尝试使用他们的Facebook登录我的网站，如果用户没有帐户，它应该重定向它们到我的注册脚本，否则它应该自动登录并重定向到登录屏幕。
您可能需要了解的信息：
要登录的密码字段使用md5
加密任何帮助将不胜感激，如果您需要更多信息，请询问：）

在上一个问题facebook registration connect中，我请求帮助设置我的注册页面。好吧，我现在已成功完成，但现在我需要这样做，这样用户也可以登录facebook。要做到这一点，我希望使用FaceBook登录按钮，如果他们点击登录并检测到他们没有注册，它将重定向到注册页面，否则它将登录。
我会使用哪些代码（示例）？你需要知道任何特殊信息吗？
