phpcms微博登陆后,不要二次注册,出现会话过时的详解

phpcms微博登陆后,不要二次注册,出现会话过时,
思路是 微博登录后,直接把用户昵称等写入数据库,
然后再执行一次,判断是否注册过,但是提示登录成功之后,总提示一次会话过期.再次登录后正常.
代码有点长,麻烦看下.

回复内容：

会话过期 你是在那一行代码判断的？

我没去判断,我用的他自带的代码
思路是:
默认是判断  一次       //检查connect会员是否绑定，已绑定直接登录，未绑定提示注册/绑定页面

如果已经绑定,则直接登录,
没绑定,我会在写入数据库后,在调用一次判断(就是把判断的代码在复制过来一次,),这时候应该已经绑定了,他还是会在提示一次回话过期呢...
