php - Gravity Forms 在 xml 中提交后将条目数据发送给第三方

Question

我对 php/curl 和重力形式的钩子相当陌生。我有 5 个表单，我正在尝试设置以使用重力表单 gform_after_submission 挂钩，以便将 xml 数据发送给第三方（运行 sql server 的 sbs Web 服务）。

这是我已经拥有的。

add_action('gform_after_submission_73', 'post_to_third_party', 10, 2);
function post_to_third_party($entry, $form) {

$post_url = 'http://mywebsite.co.uk/customers?clientid=1599999&secret=123';
$body = array(
    'brand' => $entry['20'],
    'product' => $entry['22'],
    'form_id' => $entry['21'],
    'title' => $entry['24'],
    'fname' => $entry['23'],
    'lname' => $entry['17'],
    'postcode' => $entry['14'],
    'address1' => $entry['2.1'],
    'address2' => $entry['2.2'],
    'town' => $entry['2.3'],
    'county' => $entry['2.4']   
    );
$xml = '
   <?xml version="1.0" encoding="WINDOWS-1252"?>
<webform>
        <brand>$brand</brand>
    <product>$product</product>
    <form_id>$form_id</form_id>
    <title>$title</title>
    <fname>$fname</fname>
    <lname>$lname</lname>
    <postcode>$postcode</postcode>
    <address1>$address1</address1>
    <address2>$address2</address2>
    <town>$town</town>
    <county>$county</county>
    </webform>';
var_dump($xml);

$ch = curl_init($url);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: text/xml'));
    curl_setopt($ch, CURLOPT_POSTFIELDS, $xml);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_URL, $post_url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
    $output = curl_exec($ch);
    echo $output;
    curl_close($ch);
  }

您的代码有几个问题，一个不错的 IDE 会立即显示给您。

function post_to_third_party($entry, $form)

$form从未使用过，所以省略它。
$body = array(...);

您从不使用$body，而是稍后尝试“直接”访问条目。
$xml = '...';

var_dump($xml);正如已经向您展示的那样，不插入单引号字符串（即不替换变量）。此外，您不要转义这些值，这些值可能包含 XML 中不允许的字符。
$ch = curl_init($url);

$url不存在。您要使用的值位于$post_url.
您正在使用不安全的设置cURL，使您的代码容易受到 MITM 攻击（SSL 服务器欺骗）。有关详细信息，请参阅此文档。
您没有任何用于错误检查的表格。

解决问题后，您的代码如下所示，现在应该可以工作了：

add_action('gform_after_submission_73', 'post_to_third_party', 10, 2);

function post_to_third_party($entry)
{
    $url      = 'http://mywebsite.co.uk/customers?clientid=1599999&secret=123';
    $encoding = 'WINDOWS-1252';
    $brand    = htmlspecialchars($entry['20'], ENT_XML1, $encoding);
    $product  = htmlspecialchars($entry['22'], ENT_XML1, $encoding);
    $form_id  = htmlspecialchars($entry['21'], ENT_XML1, $encoding);
    $title    = htmlspecialchars($entry['24'], ENT_XML1, $encoding);
    $fname    = htmlspecialchars($entry['23'], ENT_XML1, $encoding);
    $lname    = htmlspecialchars($entry['17'], ENT_XML1, $encoding);
    $postcode = htmlspecialchars($entry['14'], ENT_XML1, $encoding);
    $address1 = htmlspecialchars($entry['2.1'], ENT_XML1, $encoding);
    $address2 = htmlspecialchars($entry['2.2'], ENT_XML1, $encoding);
    $town     = htmlspecialchars($entry['2.3'], ENT_XML1, $encoding);
    $county   = htmlspecialchars($entry['2.4'], ENT_XML1, $encoding);

    $xml = "<?xml version=\"1.0\" encoding=\"$encoding\"?>
    <webform>
        <brand>$brand</brand>
        <product>$product</product>
        <form_id>$form_id</form_id>
        <title>$title</title>
        <fname>$fname</fname>
        <lname>$lname</lname>
        <postcode>$postcode</postcode>
        <address1>$address1</address1>
        <address2>$address2</address2>
        <town>$town</town>
        <county>$county</county>
    </webform>";

    $ch = curl_init($url);

    if ($ch === false) {
        throw new RuntimeException("Unable to initialise a session");
    }

    $result = curl_setopt_array($ch, [
        CURLOPT_POST => 1,
        CURLOPT_HTTPHEADER => ['Content-Type: text/xml'],
        CURLOPT_POSTFIELDS => $xml,
        CURLOPT_RETURNTRANSFER => 1,
        CURLOPT_URL => $url,
        CURLOPT_RETURNTRANSFER => 1,
        CURLOPT_SSL_VERIFYHOST => 2,
        CURLOPT_SSL_VERIFYPEER => 1,
    ]);

    if ($result === false) {
        throw new RuntimeException("Unable to set session options");
    }

    $output = curl_exec($ch);

    if ($output === false) {
        throw new RuntimeException("Request failed: " . curl_error($ch));
    }

    curl_close($ch);

    echo $output;
}
