jQuery.ajax CRM 上的重复线索

Question

我正在为 Wordpress 使用 Contact Form 7，我将数据发送到 CRM：

• JS文件

  • 地图形式数据与

var data_one = event.detail.inputs[0].value;
var data_two = event.detail.inputs[1].value;

- and send data with Ajax

 jQuery.ajax({
              method: "POST",
              url: post_url,
              data: { 
                    name: data_one,
                    email: data_two
              },
              cache: false
            }).done(function( html ) {

• PHP文件

$data = array(
    'User' => 'AdmWbs',
    'Password' => '**********',
    'name' => $_POST['name'], 
    'email' => $_POST['email']
);
# Create a connection
$url = 'http://...'; //url or webservice
$ch = curl_init($url);
# Form data string
$postString = http_build_query($data, '', '&');
# Setting our options
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postString);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
# Get the response
$response = curl_exec($ch);
//if there is an error send email to sys admin and do a redirect to home
if (strpos($response, 'abortProcessing') !== false) {
    sendMail("2",$response,$_POST['idprovenienza'],$_POST['email'],$_POST['indirizzoip']);
    header("Location: https://www.test.com/");
    die();  
}
curl_close($ch);

问题是，如果用户随机发送表格，我们会在 CRM 上找到 1、2、... 10 个相同的潜在客户

我如何阻止每次发送表单仅发送 1 次？

谢谢

每个发送表单发送一个 1 数据
