我正试图为wordpress网站创建一个联邦快递取货请求。当我在wordpress之外创建代码时，api和工具运行良好，但当我将相同的代码放入wordpress时，我得到的错误是

警告：非法字符串偏移量“警告：在/home/xd/public\\u html/test/wp-content/themes/dev/template-pickup-confirm中非法字符串偏移量“WebAuthenticationDetail”。php第33行注意：数组到字符串转换in/home/xd/public\\u html/test/wp content/themes/dev/template pickup confirm。php在线33

需要4个文件：pickupform。php（发布到pickup request.php的表单）pickup request。php（处理soap）联邦快递通用。php（处理常见的联邦快递功能，以防我使用其他联邦快递工具，如评级、发货、退款或取消）PickupService\\u v13。wsdl。（联邦快递webservices图书馆）

我将两个主要的php表单嵌入到wordpress的模板中。

我在（pickupform.php）one上填写表单，它会发布到取货请求。php

所以它以pickuprequest的形式停在这一行：

$request[\'WebAuthenticationDetail\'] = array(
    \'ParentCredential\' => array(
        \'Key\' => getProperty(\'parentkey\'),
        \'Password\' => getProperty(\'parentpassword\')
    ),
    \'UserCredential\' => array(
        \'Key\' => getProperty(\'key\'), 
        \'Password\' => getProperty(\'password\')
    )
);

其中getProperty（）在fedexcommon中引用此函数。php：

function getProperty($var){

  if($var == \'key\') Return \'vB12a89Q25xwv\'; 
    if($var == \'password\') Return \'FFAz8EEYEEfEZufZxu4pJc\'; 
    if($var == \'shipaccount\') Return \'510087\';
    if($var == \'billaccount\') Return \'510087\';
    if($var == \'dutyaccount\') Return \'XXX\'; 
    if($var == \'freightaccount\') Return \'XXX\';  
    if($var == \'trackaccount\') Return \'XXX\'; 
    if($var == \'dutiesaccount\') Return \'XXX\';
    if($var == \'importeraccount\') Return \'XXX\';
    if($var == \'brokeraccount\') Return \'XXX\';
    if($var == \'distributionaccount\') Return \'XXX\';
    if($var == \'locationid\') Return \'PLBA\';
    if($var == \'printlabels\') Return true;
    if($var == \'printdocuments\') Return true;
    if($var == \'packagecount\') Return \'4\';
    if($var == \'validateaccount\') Return \'XXX\';
    if($var == \'meter\') Return \'118593060\';
);
    }

因此，wordpress似乎出于某种原因不知道或没有将WebAuthenticationDetail更改为数组？

对于wordpress数组，是否应该以不同的方式编写代码？

或者这需要写在插件中吗？

应以下要求添加其他代码：

require_once(\'library/fedex-common.php5\');

//The WSDL is not included with the sample code.
//Please include and reference in $path_to_wsdl variable.
$path_to_wsdl = "wsdl/PickupService_v13.wsdl";

ini_set("soap.wsdl_cache_enabled", "0");

$client = new SoapClient($path_to_wsdl, array(\'trace\' => 1)); // Refer to http://us3.php.net/manual/en/ref.soap.php for more information
date_default_timezone_set(\'America/Los_Angeles\');
$cdate = $_POST["txtPickupDate"]. " ". $_POST["txtPickupTime"];
$datetime = new DateTime($cdate);
$tdate = $datetime->format(\'c\');

$request[\'WebAuthenticationDetail\'] = array(   //LINE 33

        ),

    \'Units\' => \'LB\' // valid values LB and KG
