阿贾克斯datapost没有得到低谷张贴网址

Question

我想发布数据到一个PHP网站，其中只包含php代码，应该在第一页上点击ID＃mR-RateableFramePicture时执行。这是由一个Ajax请求完成：

$('#mR-RateableFramePicture').dblclick(function() { 
     $.ajax({ 
      type: "POST", 
      url: 'moduleRateable/scriptSavedStyle.php', 
      data: { rateableUserID: rateableUserID, rateablePictureID: rateablePictureID}, 
      success: function() { 
       $('#DynamicContent').load('moduleRateable/scriptSavedStyle.php'); 
      } 
     }); 
    }); 

    var rateableUserID = $('input[name="rateableUserID"]').val(); 
    var rateablePictureID = $('input[name="rateablePictureID"]').val(); 

而且这里的URL目的地其AJAX员额：

<?php 
// Start the session (enable global $_SESSION variable). 
session_start(); 

// Include database-link ($conn). 
include '../../scriptMysqli.php'; 

// Make global variable to simple variable. 
$userID = $_SESSION["ID"]; 

//Save the rateable style to one owns libary of saved styles.  
$ratedUserID = $_POST['rateableUserID']; 
$ratedPictureID = $_POST['rateablePictureID']; 


$sql = $conn->query("UPDATE styles WHERE userID = '$ratedUserID;' AND 
pictureID = '$ratedPictureID' SET savedByUser = '$userID'"); 

?> 

我收到以下错误信息：

注意：未定义指数：rateableUserID在C：\ xampp \ htdocs \ mystyle \ app \ moduleRateable \ scriptSavedStyle.php上线12

注意：未定义索引：rateablePictureID in C：\ xampp \ htdocs \ mystyle \ app \ moduleRateab乐\ scriptSavedStyle.php上线13

你是不是传递变量rateableUserID和rateablePictureID的价值在您的通话$.ajax({})像下面 -

data: { rateableUserID: rateableUserID, rateablePictureID: rateablePictureID}。除非它们是全局定义的，否则您将在PHP端获得未定义的值。在进行调用之前，请确保您具有分配给rateableUserID和rateablePictureID的值。但是，您仍然必须检查您是否确实在您的发布请求中传递了该变量，因为PHP找不到密钥名称。

的功能应该有如下

$('#mR-RateableFramePicture').dblclick(function() { 
    var rateableUserID = $('input[name="rateableUserID"]').val(); 
    var rateablePictureID = $('input[name="rateablePictureID"]').val(); 

     $.ajax({ 
      type: "POST", 
      url: 'moduleRateable/scriptSavedStyle.php', 
      data: { "rateableUserID": rateableUserID, "rateablePictureID": rateablePictureID}, 
      success: function() { 
       $('#DynamicContent').load('moduleRateable/scriptSavedStyle.php'); 
      } 
     }); 
    });
