loops - Paypal DoCapture 批处理循环

Question

我正在尝试为来自 paypal 的 doCapture API 实现批处理。我有下面的代码，它只处理数据库的第一条记录......帮助!xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

<?php
include("xxxxx.php");<---- this is just the database connection

$query2="SELECT *
    FROM x where payment_status = 'Pending'";
//  WHERE custom IN (
    // SELECT custom
    //  FROM x
    //   GROUP BY custom
     //  HAVING count(custom) > 1
     // ) 
    //ORDER BY custom";
$results=mysql_query($query2);
$row2 = mysql_fetch_array($results); 
$row_count=mysql_num_rows($results);
echo $row_count;
//$auth=$row2['auth_id'];
//while($row2 =mysql_fetch_array($results)){

$arrSize=sizeof($row_count);

for ($number = 0; $number < $arrSize; $number++) {

//for($i=0; $i<$row_count; $i++){
echo $row2['auth_id']; // prints hello


//echo $row2['auth_id'];
/** DoCapture NVP example; last modified 08MAY23.
 *
 *  Capture a payment. 
*/

$environment = 'sandbox';   // or 'beta-sandbox' or 'live'

/**
 * Send HTTP POST Request
 *
 * @param   string  The API method name
 * @param   string  The POST Message fields in &name=value pair format
 * @return  array   Parsed HTTP Response body
 */
function PPHttpPost($methodName_, $nvpStr_) {
//for($i=0; $i<$row_count; $i++){
    global $environment;

    // Set up your API credentials, PayPal end point, and API version.
    $API_UserName = urlencode('');

    }

    // Extract the response details.

您只从数据库中提取一行，因为您的 $row2 = mysql_fetch_array($results); 行在您的 for 循环之外。从本质上讲，您正试图一次又一次地获取相同的付款，我敢打赌只有第一个成功。将 fetch 语句移动到 for 循环内。
