Question

我想将从Kunaki API收到的xml解析为下拉选择框。到目前为止我有这个代码，但是盒子保持空白，所以我的问题是我如何实现这个目标？我每次都会收到一个空的下拉选择框。

<?php
$context  = stream_context_create(array('http' => array('header' => 'Accept: application/xml')));
$url = 'http://kunaki.com/HTTPService.ASP?RequestType=ShippingOptions&State_Province=NY&PostalCode=11204&Country=United+States&ProductId=PX0012345&Quantity=1&ProductId=PX04444444&Quantity=1&ResponseType=xml ';

$xml = file_get_contents($url, false, $context);
$xml2 = simplexml_load_string($xml);

?>
<html>
  <head>

  </head>
  <body>

    <select>


    <Option Value=<?php  echo $value = (string)$xml2->Description[0]." Delivery Time ".(string)$xml2pt->DeliveryTime[0].(string)$xml2->Price[0];?></Option>
    </select>  
 </body>
</html>

经过一番摆弄后，我相信这就是你所追求的目标。

<?php

// Setup your context for file_get_contents
$oContext = stream_context_create(array("http" => array("header" => "Accept: application/xml")));
// Put in your URL here to get the XML from
$sURL = "http://kunaki.com/HTTPService.ASP?RequestType=ShippingOptions&State_Province=NY&PostalCode=11204&Country=United+States&ProductId=PX0012345&Quantity=1&ProductId=PX04444444&Quantity=1&ResponseType=xml";
// Parse the XML
$oXML = simplexml_load_string(file_get_contents($sURL, false, $oContext));
// Grab the data that we need from the XML
$pOptions = isset($oXML->Option) && isset($oXML->Option[0]) ? $oXML->Option : array("error" => true);
// Display everything to the page
echo "<html>";
    echo "<head>";
        echo "<title>XML Test</title>";
    echo "</head>";
    echo "<body>";
        // If there was an error, display it to the page
        if(isset($pOptions["error"]))
        {
            echo "<h3>Sorry, wrong data returned.";
            var_dump($pOptions);
        }
        else
        {
            // Loop through the array and display the dropdown
            echo "<select>";
                for($i = 0, $iCount = count($pOptions); $i < $iCount; ++$i)
                {
                    $sString = $pOptions[$i]->Description.", ";
                    $sString .= "Delivery Time: ".$pOptions[$i]->DeliveryTime." ";
                    $sString .= "($".$pOptions[$i]->Price.")";
                    echo "<option>".$sString."</option>";
                }
            echo "</select>";
        }
    echo "</body>";
echo "</html>";

?>

我重新格式化了下拉文本的显示，以便更容易阅读。在这个例子中，它使这个下拉列表：

<select>
  <option>
    USPS First Class Mail, Delivery Time: 2-5 business days ($0.66)
  </option>
  <option>
    UPS Ground, Delivery Time: 1-5 business days ($17.17)
  </option>
  <option>
    UPS 2nd Day Air, Delivery Time: 2 business days ($30.42)
  </option>
  <option>
    UPS Next Day Air Saver, Delivery Time: 1 business day ($50.17)
  </option>
</select>

您的一个问题是，您只将数据放入下拉列表的值属性中。

示例：

<option value="test"></option>

只会显示：

<select>
  <option value="test"></option>
</select>

所以你所追求的是更像这样的东西：

<select>
  <option>Test</option>
</select>

除此之外，您只是尝试显示第一个返回的选项，而不是所有选项。这就是for（）循环发挥作用的地方，它将循环显示所有返回的运输选项，无论有多少。

希望这有帮助！
