为什么 mysqli 插入不起作用？

Question

我正在尝试将数据插入到我的 MySQL 表中，但没有成功。我的代码看起来像：

$mysqli = mysqli_connect("localhost","login info");

if ($mysqli->connect_errno) {
    echo "Failed to connect to MySQL: (" . $mysqli->connect_errno . ") " . $mysqli->connect_error;
}

if (isset($_POST['submit'])) {
    $number = $_POST['number'];
    $road = $_POST['road'];
    $postcode=$_POST['postcode'];
    $price=$_POST['price'];
    $type=$_POST['type'];
    $bedrooms=$_POST['bedrooms'];
    $agent=$_POST['agent'];
    $featured=$_POST['featured'];
    $keywords=$_POST['keywords'];

    $mysqli->query("
        INSERT INTO listings-rent
            (number, road, postcode, price, type, bedrooms, agent, featured, keywords)
        VALUES
            ('$number','$road','$postcode','$price','$type','$bedrooms','$agent','$featured','$keywords')");
}

连接正常，没有返回错误。

Answer 1

您的表名应该用反引号括起来，因为它包含非字母数字字符。

INSERT INTO `listings-rent` (...) VALUES (...)

并且还请对这些值进行参数化。
