数据插入查询中的问题。

$sql = "INSERT INTO admin(name, Password, mail,country)
VALUES ("$_POST['Name']", "$_POST['Password']", "$_POST['E-mail']","$_POST['country']")";

if (mysqli_query($conn, $sql)) {
    echo "New record created successfully";
} else {
    echo "Error: " . $sql . "<br>" . mysqli_error($conn);
}

数据库已连接，但数据未存储在xamp服务器中
