Question

我一般都是PHP的新手，但我想我已经掌握了它。由于某种原因，数据没有上传到数据库：/

如果您有任何想法是错误的，或者这是一个糟糕的结构，请随时表达您的意见！在此先感谢您的帮助!!

的config.php：

    <?php
    $database = "LennysPizza";  // the name of the database.
    $server = "localhost";  // server to connect to.
    $db_user = "root";  // mysql username to access the database with.
    $db_pass = "jdish";  // mysql password to access the database with.
    $link = mysqli_connect($server, $db_user, $db_pass);
    mysqli_select_db($link, $database);
    ?>

Answer 1

isset()是一个布尔测试。你想改变：

$cheeseburger_quantity = isset($_POST['cheeseburger_quantity']);

为：

if (isset($_POST['cheeseburger_quantity'])) {
    $cheeseburger_quantity = $_POST['cheeseburger_quantity'];
}
else {
    $cheeseburger_quantity = 0;
}
