Magento-運送方式carrier.php

Question

這將是一個漫長的過程，因為我真的不知道該問些什么。

我已經在app / code / local / ParcelMonkeyLMc中創建了一個自定義送貨方式。 我希望它從parcelmonkey.co.uk API中讀取。

我的API在單獨的php文件中運行良好，但是當我將代碼移到carrier.php時，它似乎無法正常工作。

在公共函數collectRates內部，我有以下代碼：

                $quoterequest = array('parcelmonkey.request' => array(
                    'login' => array(
                        'version'       => $version,
                        'username'      => $username,
                        'password'      => $password,
                        'test'          => $testflag
                        ),
                    'requesttype' => 'quote',
                    'quote' => array(
                        'packages'  => array(
                            'noofpackages'  => 1,
                            'package1'  => array(
                                'length'        => 10,
                                'width'         => 10,
                                'height'        => 10,
                                'weight'        => 1.5
                                ),
                            ),
                        'insurance_cover'   => 0.00,
                        'collection' => array(
                            'address'   => array(
                                'postcode'  => 'PR7 1DB',
                                'country'   => 'United Kingdom'
                                )
                            ),
                        'delivery' => array(
                            'address'   => array(
                                'postcode'  => 'NW1 4RY',
                                'country'   => 'United Kingdom'
                                )
                            )
                        )
                    )
                );

      $quotereply=pmGetQuote($quoterequest, $pmapi100url);

pmGetQuote以及其他與parcelmonkey相關的功能都在頁面頂部。 如果有人需要知道確切的代碼，我可以將其發布。

$ quotereply是查詢parcelmonkey的結果。 看起來像這樣：

Array ( [replycode] => 200 [replymessage] => success [replytype] => quote [quote] => Array ( [services] => Array ( [noofservices] => 2 [service1] => Array ( [name] => TestService1Before12am [description] => Test Service 1 Before 12am [carrier] => Camel [price] => 10 [vat] => 0 [vat_rate] => 0 [insurance_cost] => 0 [insurance_cover] => 0 ) [service2] => Array ( [name] => TestService2Anytime [description] => Test Service 2 Anytime [carrier] => Pigeon [price] => 5 [vat] => 0 [vat_rate] => 0 [insurance_cost] => 0 [insurance_cover] => 0 ) ) ) [custom] => Array ( [data] => [orderid] => ) )

在單獨的php文件中，我可以像這樣抓取特定字段：

$num = $quotereply['quote']['services']['noofservices'];

但是，當我在carrier.php中嘗試此操作時，我得到一個空值。 我知道這是漫長的過程，但是我不確定你們需要什么細節。

我為什么突然得到null而不是值是有原因的嗎？

謝謝

========================

編輯：根據要求，所有的ParcelMonkey函數，我已經放在Carrier.php中。 我發現該函數sendandgetreply返回一個錯誤，“通信錯誤：響應時出錯”。 在獨立的PHP文件上不會發生這種情況。

$username       = 'username';   /* MODIFY ME */
$password       = 'password';   /* MODIFY ME <- note, also referred to as key. */

$version        = '100';    /* Protocol version. */

$testflag       = '1';      /* Test flag, 0=live, 1=test. MODIFY ME WHEN YOU GO LIVE */

$pmapi100url    = 'http://www.parcelmonkey.co.uk/api/pmapi100.php';

function pmGetQuote($requestphparray, $pmapi100url)
//       ~~~~~~~~~~
//
// getQuote.
//
// Call this routine with the collection and delivery addresses and it will return
// a list of available services from Parcel Monkey with costs.
//
// As input it takes a PHP array and it returns the reply in a PHP array.
//
{
// Send and get reply.
$replyphparray = sendandgetreply($requestphparray,
                                 $pmapi100url);

return $replyphparray;
}

Answer 1

我已經弄清楚了，基本上是下面的代碼：

$username       = 'username';   /* MODIFY ME */
$password       = 'password';   /* MODIFY ME <- note, also referred to as key. */
$version        = '100';    /* Protocol version. */
$testflag       = '1';      /* Test flag, 0=live, 1=test. MODIFY ME WHEN YOU GO LIVE */
$pmapi100url    = 'http://www.parcelmonkey.co.uk/api/pmapi100.php';

需要在collectRates函數內。

經過大量頭部抓傷之后，這種簡單的修復方法。
