Php 无法将用户注册详细信息插入数据库

我不能在注册后将用户插入数据库，我已经做了所有我能做的，但没有成功，我真的需要在这里提供帮助，请我想知道我的脚本中哪里做错了

这是我的注册html脚本：

像这样更改PHP脚本并尝试，如果没有得到错误，可能是验证错误

$id=$fullname=$username=$password=$email=$country= $phonenumber=$alternativephonenumber=$referrer=$paymentmode="";
if(isset($_POST['submit_signup']))  //simplified validation 
{  

if(isset($_POST['id'])){
$id= $_POST['id'];  

}

if(isset($_POST['fullname'])){
$fullname= $_POST['fullname'];  
}
else{
    echo 'please enter your fullname';
}

if(isset($_POST['username'])){
$username= $_POST['username'];  
}
else{
    echo 'enter your username';
}

if(isset($_POST['password'])){
$password= $_POST['password'];  
}
else{
    echo 'enter your password';
}

if(isset($_POST['email'])){
$email= $_POST['email'];    
}
else{
    echo 'enter your email';
}

if(isset($_POST['country'])){
$country= $_POST['country'];    
}
else{
    echo 'enter your country';
}

if(isset($_POST['phonenumber'])){
$phonenumber= $_POST['phonenumber'];    
}
else{
    echo 'enter your phonenumber';
}

if(isset($_POST['alternativephonenumber'])){
$alternativephonenumber= $_POST['alternativephonenumber'];  
}
else{
    echo 'enter your alternativephonenumber';
}

if(isset($_POST['referrer'])){
$referrer= $_POST['referrer'];  
}
else{
    echo 'enter your referrer';
}

if(isset($_POST['paymentmode'])){
$paymentmode= $_POST['paymentmode'];    
}
else{var_dump($_POST['id']);
    echo 'enter your paymentmode';
}
}
    else {
        echo 'nah';

    }

    $serverhost='localhost';
$serverdb='charles';
$serveruser='root';
$serverpassword='';




try{ 
    $connect= new PDO("mysql:host=$serverhost;dbname=$serverdb;" , $serveruser, $serverpassword);
 $connect->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
     } 
      catch( PDOException $e)
        {
            echo $e->getmessage();
        }

     if($connect){
        echo 'database successful!';
     }


$sql="INSERT INTO users(id, fullname, username, password, email, country, phonenumber, alternativephonenumber, referrer, paymentmode)VALUES(:id, :fullname, :username, :password, :email, :country, :phonenumber, :alternativephonenumber, :referrer, :paymentmode)";

$query=$connect->prepare($sql);
$query->bindParam(':id', $id, PDO::PARAM_INT);
$query->bindParam(':fullname', $fullname, PDO::PARAM_STR);
$query->bindParam(':username', $username, PDO::PARAM_STR);
$query->bindParam(':password', $password, PDO::PARAM_STR);
$query->bindParam(':email', $email, PDO::PARAM_STR);
$query->bindParam(':country', $country, PDO::PARAM_STR);
$query->bindParam(':phonenumber', $phonenumber, PDO::PARAM_INT);
$query->bindParam(':alternativephonenumber', $alternativephonenumber, PDO::PARAM_INT);
$query->bindParam(':referrer', $referrer, PDO::PARAM_STR);
$query->bindParam(':paymentmode', $paymentmode, PDO::PARAM_STR);
$query->execute();

所作的修改：

简化了验证
删除了不必要的变量赋值，如果您使用的是
isset
，则不要将其赋值到
isset
使用数据库名称的变量更新数据库名称
最后一个建议是，如果要回显验证错误以进行测试，则可以，否则请保留一个变量并将其回显到正确的位置。并将插入查询代码块放入验证中。
使用css，使用类、ID或父>子选择器等指定样式，而不是不可管理的内联样式

DIV元素不使用标记末尾的
/
（请参阅原始代码中的电子邮件部分）

没有输入类型
POST
（
）-可能一个按钮会更好

id
字段隐藏在HTML中，但db可能为此使用了一个
自动增量
字段（主键），因此无需发送此值-用户在提交表单之前不会知道这一点，也不会阻止他们使用任何可能需要的数字

执行时有错误吗？
id
字段是隐藏的，因此用户如何输入值？@kuru，执行时没有错误execution@RamRaider，id字段不是由用户输入的，请记住数据库更新id由自己完成我已经完成了您建议的所有操作，但仍然没有插入到数据库中，我真的很困惑，如果您使用id作为自动增量，请从插入查询中删除其他事件和trythanks@Ramraider以获得您的帮助，但仍然没有插入，尽管它显示了一条成功消息，但没有插入用户，我下一步将做什么，我想弄清楚这一点，并知道它不，它显示的消息是'成功'，正如您在脚本中指出的，如果它成功了，但没有insertionI只是为上述设置了一个完整的端到端测试（只进行了一些小的编辑以适应数据库），它工作得很好。多亏了大家，我已经解决了这个问题，我现在可以将用户插入到我的数据库中，非常感谢@RamRaider为我提供了详细的帮助。爱你的家伙谢谢大家，我已经解决了这个问题，我现在可以将用户插入我的数据库，特别感谢@RamRaider为我提供了详细的帮助。我爱你们
