登录页面这是登录.php它工作正常，直到我只是注册并注销然后登录，但是当我登录并在我的编辑页面中编辑详细信息.php然后在注销后注销时，我无法再次登录说"电子邮件或密码组合错误"，这是一条消息名称和密码不匹配。

编辑.php页面这是编辑.php页面，它产生了问题，所以请帮助我解决这个问题，问题是每当我编辑此页面中的任何用户详细信息然后注销并尝试再次登录时，它不允许我再次登录说"电子邮件和密码组合是错误的"（这是回声消息）。我试图从早上开始解决这个问题，但没有发现问题出在哪里。

将$password=mysqli_real_escape_string($conn,sha1($_POST['password']));替换为edit.php中的$password= mysqli_real_escape_string($conn,$_POST['password']);。

您在edit.php中申请了两次SHA1。因此，它在插入数据库之前对密码进行了两次加密。登录时，您只加密一次，因此密码不匹配，因此出现错误。

对于第二个问题，将 <option> 的代码替换为以下代码：

<select name="dob">
<? php
   $i;
   for($i = 1; $i < 31; $i++)
   {
        if($i == $_SESSION['usersession']['dob'];)
           echo '<option selected="selected" value = "'.$i.'">'.$i.'</option>'
        else
           echo '<option value = "'.$i.'">'.$i.'</option>'
   }
?>
</select>
