这个为什么href后面的等号没有变色?是什么问题啊?求指教~新手 你这样写是正确的啊。
echo "<script>alert('登陆成功');window.location.href='index.php' ;</script>";
echo "<script>alert('登陆失败');window.location.href='login.php' ;</script>";
这个分号在里面的吧。

那为什么不管我输入的用户名与密码是否正确它都跳转到空白页呢?
这个是检查用户名和密码的程序,帮忙看看哪里出错了啊?
那个空白页?你的文件不存在?404了?
是不是$_POST[""]没有吧,把你登陆界面的代码发出来看下

这个是检查用户名和密码的程序,帮忙看看哪里出错了啊? 首先你判断的是表单的输入框是否存在,这样的话只要你输入东西就会跳到index.php页面;第二,你应该判断$_POST['username'],就是输入的用户名是否在数据库中存在,你可以先遍历出数据库中的用户名,然后判断$_POST['username']是存在于其中;第三,你的index.php存在吗?或者是你的路径写错了。

我把那个判断表单是否上传那一句if(isset。。。删掉了又试了试(因为我想着登陆界面直接作用到判断文件,所以这个判断语句应该可以不要的吧),用了正确的用户名和密码但是登录失败。。。
