Question

当我试图创建MySQL订单时，我遇到了一个问题。它可以毫无问题地连接数据库，但与其发送表格中提供的信息，不如发送一堆0。我不确定是什么问题。有任何想法吗？在下面，您可以找到数据库条目：

<?php

define('DB_NAME', '');
define('DB_USER', '');
define('DB_PASSWORD', '');
define('DB_HOST', '');

$connection = mysqli_connect(DB_HOST, DB_USER, DB_PASSWORD);

if(!$connection){
die('Database connection failed: ' . mysqli_connect_error());
}

$db_selected = mysqli_select_db($connection, DB_NAME);

if(!$db_selected){
die('Can\'t use ' .DB_NAME . ' : ' . mysqli_connect_error());
}

echo 'Connected successfully';

$name = $_POST ['name'];
$email = $_POST ['email'];
$discord = $_POST ['discord'];
$website = $_POST ['website'];
$color = $_POST ['color'];
$budget = $_POST ['budget'];

$sql = "INSERT INTO orderform (name, email, discord, website, color, budget) VALUES ('$name', '$email', '$discord', '$website', '$color', '$budget')";

if (!mysqli_query($connection, $sql)){
die('Error: ' . mysqli_connect_error($connection));
}

是否所有PHP都包裹在if语句中，以检查是否确实按下了“提交”按钮，或者它只是在页面加载时运行，而没有人有机会填写并提交表格？

    if(isset($_POST['submit'])) {
      // all your php in here...
    }

将表单信息发送到数据库时，它只会发送一堆0
