PHP 表格不會插入 MYSQL
[英]PHP form won't insert into MYSQL
問題描述
有很多這樣的錯誤，但這個是我的。
我有一個 PHP 票務類型表單，我想將信息插入 MYSQL 數據庫。
這是 PHP 表格：
<html lang="en" dir="ltr">
<head>
<meta charset="utf-8">
<title></title>
</head>
<body>
<form name="ticket-form" id="ticket-form" action="get_response.php" method="POST">
<p>Please provide your first name: <input type="text" name="firstName" id="firstName" placeholder="John" required></p>
<p>Please provide your last name: <input type="text" name ="lastName" id="lastName" placeholder="Smith" required></p>
<p>Please indicate if you are a company or a contractor:
<input type="radio" name="clientType" id="clientType" value="company">Company
<input type="radio" name="clientType" id="clientType" value="contractor" checked>Contractor</p>
<p>Please provide an email address: <input type="email" name="email" id="email" placeholder="John123@example.com"><br></p>
<p>Please provide a phone number if you'd prefer: <input type="text" name="number" id="number" max="13" placeholder="07654321234"><br></p>
<p>Please detail your query, going in to as much detail as possible: </p>
<textarea name="query" id="query" rows="8" cols="80" placeholder="Please detail the nature of your issue, going in to as much detail as possible."></textarea><br><br>
<input type="submit" name="submit" value="Submit">
</form>
</body>
</html>
這是get_response.php
<?php
require_once("config.php");
require_once("index.php");
$datetime = new DateTime();
$datestring = $datetime->format('d-m-Y H:i:s');
$first_name = mysqli_real_escape_string($conn, $_POST['firstName']);
$second_name = mysqli_real_escape_string($conn, $_POST['lastName']);
$client_type = mysqli_real_escape_string($conn, $_POST['clientType']);
$email_address = mysqli_real_escape_string($conn, $_POST['email']);
$query = mysqli_real_escape_string($conn, $_POST['query']);
$phone_number = mysqli_real_escape_string($conn, $_POST['number']);
$sql = "INSERT INTO
tickets (first_name, second_name, client_type, email_address, phone_number, query)
VALUES
('$first_name', '$second_name', '$client_type', '$email_address', '$phone_number', '$query')";
if($conn->query($sql)){
echo "<p>Thank you for your email!</p>
<p> We aim to respond to your query as soon as possible.
Please allow 2 business days for a response and check spam folders.</p>";
}
else
{
die('There was an error running the query [' . mysqli_error($conn) . ']');
}
// else
// {
// echo "<p>Please supply valid information.</p>";
// }
mysqli_close($conn);
?>
php config.php
將指示與 $conn 變量的成功連接，但要消除此問題：
<?php
$servername = "xxxxx";
$username = "xxxxx";
$password = "xxxxx";
$dbname = "tickets";
$conn = mysqli_connect($servername, $username, $password, $dbname);
if($conn->connect_error){
die("Connection failed: " . $conn->connect_error);
} ?>
php get_response.php
將空數據插入數據庫。 然而，表格並不能通過發布信息來工作。
我知道可能還有其他錯誤。 我對 PHP 和 MYSQL 非常陌生。 任何幫助深表感謝。 提前致謝。
編輯：根據要求提供一些錯誤日志。這就是今天的全部內容。

Edit2：解決了，有點。
我嘗試在我的常規 Mac OS X 操作系統中重新制作表單，它工作正常。 虛擬盒子似乎存在根本性的問題，它與現代 OS X 軟件的通信方式或某些個人配置。 雖然我可以在 Linux 命令行中連接到 mysql，但它無法通過表單工作。

在安裝 MS SQL 服務器時，我有 20 分鍾的空閑時間，如此迅速地重構了您的代碼，以利用prepared statements來緩解 SQL 注入攻擊。 它沒有經過測試，所以可能會有我忽略的小錯誤，但我希望它會被證明是有用的
