MailChimp使用API​​ 3.0添加订阅者PHP

Question

我正在尝试添加一个将新订阅者添加到我的MailChimp列表的php文件。这里是我的形式应触发php文件来添加新用户：

<form action="/scripts/freemonth_action.php" class="email_form_freemonth" method="post"> 
    <h3>Get your first month free</h3> 
    <div class="form-group customised-formgroup"> <span class="icon-user"></span> 
     <input type="text" name="full_name" class="form-control" placeholder="Name"> 
    </div> 
    <div class="form-group customised-formgroup"> <span class="icon-envelope"></span> 
     <input type="email" name="email" class="form-control" placeholder="Email"> 
    </div> 
    <!--<div class="form-group customised-formgroup"> <span class="icon-telephone"></span> 
     <input type="text" name="phone" class="form-control" placeholder="Phone (optional)"> 
    </div>--> 
    <div class="form-group customised-formgroup"> <span class="icon-laptop"></span> 
     <input type="text" name="website" class="form-control" placeholder="Website (optional)"> 
    </div> 
    <!--<div class="form-group customised-formgroup"> <span class="icon-bubble"></span> 
     <textarea name="message" class="form-control" placeholder="Message"></textarea> 
    </div>--> 
    <div> 
     <br> 
     <button style="margin: 0 auto" type="submit" class="btn btn-fill full-width">GET FREE MONTH<span class="icon-chevron-right"></span></button> 
    </div> 
</form> 

这里是freemonth_action.php：

<?php 
session_start(); 
if(isset($_POST['submit'])){ 
    $name = trim($_POST['full_name']); 
    $email = trim($_POST['email']); 
    if(!empty($email) && !filter_var($email, FILTER_VALIDATE_EMAIL) === false){ 
     // MailChimp API credentials 
     $apiKey = '6b610769fd3353643c7427db98d43ad6-us16'; 
     $listID = '0cf013d1d9'; 

     // MailChimp API URL 
     $memberID = md5(strtolower($email)); 
     $dataCenter = substr($apiKey,strpos($apiKey,'-')+1); 
     $url = 'https://' . $dataCenter . '.api.mailchimp.com/3.0/lists/' . $listID . '/members/' . $memberID; 

     // member information 
     $json = json_encode([ 
      'email_address' => $email, 
      'status'  => 'subscribed', 
      'merge_fields' => [ 
       'NAME'  => $name, 
      ] 
     ]); 

     // send a HTTP POST request with curl 
     $ch = curl_init($url); 
     curl_setopt($ch, CURLOPT_USERPWD, 'user:' . $apiKey); 
     curl_setopt($ch, CURLOPT_HTTPHEADER, ['Content-Type: application/json']); 
     curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
     curl_setopt($ch, CURLOPT_TIMEOUT, 10); 
     curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'PUT'); 
     curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); 
     curl_setopt($ch, CURLOPT_POSTFIELDS, $json); 
     $result = curl_exec($ch); 
     $httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE); 
     curl_close($ch); 
     echo json_encode($result); 

     // store the status message based on response code 
     if ($httpCode == 200) { 
      $_SESSION['msg'] = '<p style="color: #34A853">You have successfully subscribed to CodexWorld.</p>'; 
     } else { 
      switch ($httpCode) { 
       case 214: 
        $msg = 'You are already subscribed.'; 
        break; 
       default: 
        $msg = 'Some problem occurred, please try again.'; 
        break; 
      } 
      $_SESSION['msg'] = '<p style="color: #EA4335">'.$msg.'</p>'; 
     } 
    }else{ 
     $_SESSION['msg'] = '<p style="color: #EA4335">Please enter valid email address.</p>'; 
    } 
} 

我什至不知道如何调试这一点，因为当我做echo $结果（或类似的东西）我没有看到页面上的任何内容或登录到控制台。我也打开任何使用JavaScript的建议，只要它仍然是3.0 API。

您的订阅代码正常工作。您没有看到任何结果的原因是因为isset($_POST['submit'])查找名称为“提交”而非“提交”类型的元素。就在name属性添加到您的按钮，它应该为你工作：

<button style="margin: 0 auto" type="submit" name="submit" class="btn btn-fill full-width">GET FREE MONTH<span class="icon-chevron-right"></span></button> 

此外，你应该保持API密钥秘密，因此其他人无法通过API访问您的MailChimp帐户。我建议禁用当前的密钥并创建一个新密钥。有关更多详细信息，请参阅MailChimp关于API Keys的知识库文章。
