Answer 1

打开 /include/userlogin.class.php

找到

@session_register($this->keepUserIDTag);
$_SESSION[$this->keepUserIDTag] = $this->userID;

@session_register($this->keepUserTypeTag);
$_SESSION[$this->keepUserTypeTag] = $this->userType;

@session_register($this->keepUserChannelTag);
$_SESSION[$this->keepUserChannelTag] = $this->userChannel;

@session_register($this->keepUserNameTag);
$_SESSION[$this->keepUserNameTag] = $this->userName;

@session_register($this->keepUserPurviewTag);
$_SESSION[$this->keepUserPurviewTag] = $this->userPurview;

@session_register($this->keepAdminStyleTag);
$_SESSION[$this->keepAdminStyleTag] = $adminstyle;

修改成：

if (!isset($_SESSION[$this->keepUserIDTag]))
$_SESSION[$this->keepUserIDTag] = $this->userID;

if (!isset($_SESSION[$this->keepUserTypeTag]))
$_SESSION[$this->keepUserTypeTag] = $this->userType;

if (!isset($_SESSION[$this->keepUserChannelTag]))
$_SESSION[$this->keepUserChannelTag] = $this->userChannel;

if (!isset($_SESSION[$this->keepUserNameTag]))
$_SESSION[$this->keepUserNameTag] = $this->userName;

if (!isset($_SESSION[$this->keepUserPurviewTag]))
$_SESSION[$this->keepUserPurviewTag] = $this->userPurview;

if (!isset($_SESSION[$this->keepAdminStyleTag]))
$_SESSION[$this->keepAdminStyleTag] = $adminstyle;
