我已经尝试了几个小时才能使这个工作，并且非常感谢帮助，因为我认为这是一个我不知道的小错字。我正在为地址创建一个搜索栏，当有人搜索时，它会将他们的地址添加到数据库中，但每次我搜索一个空白行都会添加到数据库中，这让我觉得变量是空的但是我无法弄清楚我的生活如何填补它们。

如果显而易见，任何帮助都会非常感激和抱歉。
答案 0 :(得分：2)
这些是问题
name属性，这是表单字段发布所必需的disable属性，永不发布已停用的属性字段值，而是使用readonly属性使用print_r($_POST);查看提交表单后要发布的值。
所以这里是完整的代码

$host = 'localhost';
$user = 'root';
$pass = '';
$database = 'addressTest';
$con = mysqli_connect($host, $user, $pass, $database);
if ($con){
echo 'successfully connected';
}
$number = $street = $town = $county = $country = '';
if ($_SERVER["REQUEST_METHOD"] == "POST") {
//print_r($_POST); use this to debug POST data
$number = $_POST["street_number"];
$street = $_POST["route"];
$town = $_POST["locality"];
$country = $_POST["country"];
$sql = "INSERT INTO address (Number, Street, City, State, Country) VALUES ('$number', '$street', '$town', '$county', '$country')";
$insert = mysqli_query($con, $sql);
if ($insert){
echo "inserted successfully";
}
}
