问题描述
好的，所以我正在尝试从 javascript 向 PHP 发送数据，我一直在用 int 做的很好。但是，我似乎无法用字符串来做到这一点。
在下面的代码中，姓名、电子邮件、公司、电话、城市、州和国家都是字符串字段。其他一切都是int。整数传输得很好，我已经对变量发出警报，我知道它们填充了正确的数据。

仅包含问题的 TLDR 代码段

let email = document.getElementById("Email").innerHTML;
let company = document.getElementById("Company").innerHTML;
let phone = document.getElementById("Phone").innerHTML;
let city = document.getElementById("City").innerHTML;
let state = document.getElementById("State").innerHTML;
let country = document.getElementById("Country").innerHTML;
// Converting JSON data to string
var data = JSON.stringify({ "Name": name,"cdnlptrc": cdnlptrc });
// Sending data with the request
xhr.send(data);
所以我将这些内容发送到 PHP 文档进行处理，但数据从未到达字符串变量。不过 int 变量处理得很好。
(PHP) 只包含问题
$data = json_decode(file_get_contents("PHP://input"));
$myfile = fopen("FilledOut.csv","a") or die("Unable to open file!");
$txt = "\n $data->name,$data->email,$data->company,$data->phone,$data->city,$data->state,$data->country,$data->ActiveNumberOfMolds,$data->PercentOfDownMolds,$data->RepairRatePerHour,$data->AverageProfitPerPressHour,$data->AverageNumberOfLiftersPerMold,$data->rlfcical,$data->LifterCostDifference,$data->anhpl,$data->alcrflpm,$data->plddm,$data->cdbclval,$data->emuupi,$data->mrrpa,$data->acrnm,$data->pldtd,$data->cdnlptrc,$ipaddress,$date,$time";
fwrite($myfile,$txt);
fclose($myfile);
服务器说字符串变量未定义。
这是服务器说的：

为什么处理字符串失败，而处理整数却没有问题？
解决方法
您的 javascript 对象包含大写属性，而在您的 PHP 代码中，您需要小写属性。
编辑您的 JS 代码以
var data = JSON.stringify({
"name": name,"email": email,"company": company,"phone": phone,"city": city,"state": state,"country": country,...
});
