Question

我正在本地主机上运行我的项目，并在更新我的xampp后收到此错误。以前一切都很好。

通知：未定义索引：第4行E：\ Xammpp \ htdocs \ trms \ index.php中的页面 通知：未定义索引：记住第5行的E：\ Xammpp \ htdocs \ trms \ index.php 无法连接数据库

<?php
include_once 'include/processes.php';
$Login_Process = new Login_Process;
$Login_Process->check_login($_GET['page']);
$Login = $Login_Process->log_in($_POST['user'], $_POST['pass'], $_POST['remember'], $_POST['page'], $_POST['submit']); 

include_once 'templates/header.php'; 
?>

数据库文件代码

<?php

    #Database Information
    //Database Server (localhost)

    //define("DBHOST","213.171.200.57");
    define("DBHOST","127.0.0.1");
    //define("DBHOST”,”localhost”);

    //Database Username
    define("DBUSER", "root");
    //Database Password

    define("CURRENCY","currencies");
    //define("PAYMENT","payments");

    //Location Information

    //Path of script with trailing slashes
    define("Script_Path","/trms/");


    // Path in your webfiles with directory name uploads
    define("Upload_Path","../uploads/");


    //URL of script (no trailing slash)
    define("Script_URL","http://localhost/trms");

如果您使用的是PHP 7.x，请使用null coalescing operator检查$_GET['page']：

$page = $_GET['page'] ?? '';

如果存在并且不为NULL，则返回其第一个操作数；除此以外它返回它的第二个操作数。

对于较早的PHP版本：

$page = isset($_GET['page']) ? $_GET['page'] : '';

<?php

include_once 'include/processes.php';

$page = $_GET['page'] ?? ''; // this is equivalent to $page = isset($_GET['page']) ? $_GET['page'] : '';

$Login_Process = new Login_Process;
$Login_Process->check_login($page);
$Login = $Login_Process->log_in($_POST['user'], $_POST['pass'], $_POST['remember'], $_POST['page'], $_POST['submit']); 

include_once 'templates/header.php'; 
?>

如何解决“ E：\ Xammpp \ htdocs \ trms \ index.php中的未定义索引：页面”错误？
