Question

尝试使用PHP插入MySQL表时，出现语法错误。我从node.js向该页面发送了一个POST请求，它应该处理该请求并将其发送到数据库，但是它只会引发语法错误（1064）。我是这里的新手，所以我不知道该在这里输入什么，但是很高兴提供更多信息。

<head>
</head>
<body>  

<?php
//Define the variables and set to empty values
$steam = $load = $weight = $source_city = $destination_city = $trailer_damage = $income = $distance = $fuel = $collisions = $speeding = "";
//Set them to the values of the request
$steam = $_POST["steam"];
$load = $_POST["load"];
$weight = $_POST["weight"];
$source_city = $_POST["source_city"];
$destination_city = $_POST["destination_city"];
$trailer_damage = $_POST["trailer_damage"];
$income = $_POST["income"];
$distance = $_POST["distance"];
$fuel = $_POST["fuel"];
$collisions = $_POST["collisions"];
$speeding = $_POST["speeding"];
?>
<h2> Just for submitting the data to the MySQL!
Don't do anything with this page! </h2>

<?php
//Define the connection configuration and the datalist
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "hello";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

$sql = 'INSERT INTO MyTable (steam, load, weight, source_city, destination_city, trailer_damage, income, distance, fuel, collisions, speeding)
VALUES ($steam, $load, $weight, $source_city, $destination_city, $trailer_damage, $income, $distance, $fuel, $collisions, $speeding)';

if ($conn->query($sql) === TRUE) {
    echo "New record created successfully";
} else {
    echo "Error: " . $sql . $conn->error;
}

$conn->close();
?>

这是错误：

也很抱歉，仅对代码进行了基本的编辑，但是我不确定要编辑什么，而不要进行什么编辑，因此我将其包括为原始内容；）感谢您的帮助。

原因是“ load”是关键字。要使您的列使用关键字作为其名称，您必须将其用反引号“关键字”括起来。通常最好总是这样做。

INSERT INTO MyTable (`something`, `load`) VALUES ("a", "b")

以下是MySQL 5.6的关键字列表： https://dev.mysql.com/doc/refman/5.6/en/keywords.html
