Question

在这里真的很挣扎，我相信这很简单。我正在尝试使用xmlhttp和PHP后端从移动APP上传一些数据。

首先尝试使用以下JavaScript;

＆＃13;

 <script>
            function sendData()
             {
                
                 var xmlhttp = new XHRObject();                              
                 
                 xmlhttp.onreadystatechange=function()
                 {
                     if (xmlhttp.readyState==4 && xmlhttp.status==200)
                    {                    
                    xmlhttp.responsetext will have what is sent back - use Print_R in php
                    document.getElementById('ResponseDiv').innerHTML = "Entry Posted";          
                    }
                 }     
           
                 var d = new Date();
                 var n = d.toLocaleString(d);
                 var uid = intel.xdk.device.uuid;     
                               
                 var postdata = '{';
                 postdata += '"SBP_VehicleReg": "' + document.getElementById('VehicleReg').value + '"';
                 postdata += ',"SBP_Uuid": "' + uid + '"';
                 postdata += ',"SBP_PostedDate": "' + n + '"';
                 postdata += ',"SBP_Category": "' + document.getElementById('Category').value + '"';
                 postdata += ',"SBP_Details": "' + document.getElementById('Details').value + '"';
                 postdata += '}';   
                 
                 xmlhttp.open("POST","http://sxxxx.co.uk/SBPostPost.php", false);
                 xmlhttp.setRequestHeader("Content-type","multipart/form-data");
                 
              
                 xmlhttp.send(postdata);
             }
        </script>

＆＃13;

....使用Debug我得到以下显示为POSTed; （对我来说看起来不错）

＆＃13;

＆＃13;

但是当我尝试将字段输出时 - 使用以下PHP - 我什么也得不到; 尝试了各种各样的事情;

    *$headers = getallheaders();
    while (list($header, $value) = each($headers)) {
    echo "$header: $value<br>\n";*

这回应了标题

*if ($headers["Content-Type"] == "multipart/form-data") {
        echo "SUCCESS";
    }*

以“成功”

作为回应

  *foreach ($_POST as $param_name => $param_val) {
echo "Param: $param_name; Value: $param_val<br />\n";
}*

但这没有任何意义;

 *echo $_POST['SBP_Uuid'];*

这给出了未定义变量SBP_Uuid

任何想法??

您可以使用var_dump($_POST)查看收到的所有数据，然后检查您是否使用了错误的密钥。

努力从POST中获取数据 - 进入圈子。？
