PHP：程序不起作用。我不明白错误

我创建了这3页表单。第一是注册，第二个是进入和退出日期，现在是第三个，我试图让用户在价值停车，见面和招呼服务停车场和灵活的停车位之间进行选择。但是，我在每个按钮旁边创建了一个"选择"按钮，当我单击按钮时，我检查数据库，只有ID和用户名被更新，停车的名称不会出现。这是我的代码：

<?php
session_start();
$error=true;
$users=$_SESSION['tsmUserName'];
$Parkingname="";
if (isset($_POST['tsmValueaParking'])){
    $name="value Parking";
    $error=false;
}
if (isset($_POST['tsmMeetGreetService'])){
    $name="Meet and Greet Service Parking";
$error=false;
}
if (isset($_POST['tsmFlexible'])){
    $name="Flexible Parking";
    $error=false;
}
if($error==false){
    require_once("connection.php");
            $my_query="INSERT INTO `parking`(`Id`, `name`, `username`) VALUES (NULL,'$name','$users')";
            $result=mysqli_query($connection,$my_query);
            if($result)
            {
                echo 'thank you';
            }
            else
            {
                echo 'error';
            }
            mysqli_close($connection);
}
?>

问题可能是由于您的表格由于字段类型而无法正确提交。更改您的所有：

<input type="button"

<input type="submit"

然后尝试再次提交。我认为如果要提交开关类型，您将看到您的$_POST正常工作。

在旁注上，如果您具有用户提交的数据，则需要确保谨慎地绑定参数。您想避免注入SQL。
