此问题的继续：将仅选中的复选框添加到数据库-PHP
我正在尝试仅将指定的选定复选框添加到我的数据库中。正如该问题中所建议的，我的代码如下所示：
<html>
<head>
<?php
// First we execute our common code to connection to the database and start the session
require("common.php");
// At the top of the page we check to see whether the user is logged in or not
if(empty($_SESSION['user']))
{
// If they are not, we redirect them to the login page.
header("Location: login.php");
// Remember that this die statement is absolutely critical. Without it,
// people can view your members-only content without logging in.
die("Redirecting to login.php");
}
// Everything below this point in the file is secured by the login system
// We can display the user's username to them by reading it from the session array. Remember that because
// a username is user submitted content we must use htmlentities on it before displaying it to the user.
$con = mysql_connect("localhost","root","");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
?>
</head>

当我运行它时，我得到：未定义的索引：西班牙注意：未定义的索引：法国（对所有列出的国家都这样做）。我不确定如何解决这个问题。任何帮助将不胜感激。
编辑：一些研究建议使用 print_r 可以帮助我诊断问题。print_r($arr[0]) 给出。这让我更加困惑，因为在我看来它应该可以工作。数组（[UK] => UK [SPAIN] => SPAIN [FRANCE] => FRANCE [BENELUX] => BENELUX [GERMANY] => GERMANY [SWEEDEN] => SWEEDEN）
