//我写的这个小程序没有什么恶意攻击网站的意思，就是老师布置的一个小作业，自己假期在学校做了挺长时间了登录可以成功，发帖就一直不成功。可是发帖我真的不知道哪里错了，也没有改对过，这个问题已经快两周了。我真心的请教，希望哪位会的话可以帮我看一下程序，真的谢谢你们了。

看了一下 论坛是用 DiscusZ 做的, 使用了 formhash 做验证。 你不能使用同样的formhash 发新帖, 这样通不过验证。
在发帖之前需要 访问发新帖的page - 比如 forum.php?mod=post&action=newthread&fid=66 得到的page中 会有
<input type="hidden" name="formhash" id="formhash" value="e26b3058" />
<input type="hidden" name="posttime" id="posttime" value="1344559086" />
<input type="hidden" name="wysiwyg" id="e_mode" value="1" />
取到 formhash 和posttime的值 然后带入你的sendinfo方法 这样才能发帖。
