Php Undifend 索引 [重复]-解网

问：

使用 PHP 的“注意：未定义的变量”、“注意：未定义的索引”、“警告：未定义的数组键”和“注意：未定义的偏移量” （29 个答案）

8年前关闭。

我以前用过这段代码。现在我对其他脚本使用了相同的代码，但现在我收到了通知。我想把这些信息放在数据库中，但我总是得到未定义的索引。不管我做什么。

 <pre><code>
    <?php
    define('DB_NAME', 'videonaardvd');
    define('DB_USER', 'root');
    define('DB_PASSWORD', 'usbw');
    define('DB_HOST', 'localhost');

$Type = $_POST['Type'];
$Aantal = $_POST['Aantal'];
$ExtraKopie = $_POST['ExtraKopie'];
$Naam = $_POST['Naam'];
$Adres = $_POST['Adres'];
$Postcode = $_POST['Postcode'];
$Plaats = $_POST['Plaats'];
$Telefoon = $_POST['Telefoon'];
$Email = $_POST['Email'];
$Datum = $_POST['Datum'];
        $link = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD);

        if(!$link){
            die('could not connect:' . mysql_error()); 
            }
        $db_selected = mysql_select_db (DB_NAME, $link);

        if (!$db_selected) {
            die('Can\'t use ' . DB_NAME . ': ' . mysql_error ());
            }

        $sql = "INSERT INTO gegevens (Type,Aantal,ExtraKopie,Naam,Adres,Postcode,Plaats,Telefoon,Email,Datum)  
                VALUES ('$Type','$Aantal','$ExtraKopie','$Naam','$Adres','$Postcode','$Plaats','$Telefoon','$Email','$Datum'";

        if(!mysql_query($sql)){
            die('Er is iets fout gegaan. Probeer het later opnieuw.: '. mysql_error());
            }

?>
