如何为 Mailchimp 上的列表成员添加标签？

Question

我想向 mailchimp 列表中的特定用户添加标签

$email = "toto@example.com";
$tag="test";
$userid = md5( strtolower( $email ) );


$data = array(
    'apikey'        => $mailchimp_api_key,
    'email_address' => $email,
    'tags' => array(
        'name' => $tag,
        'status' => 'active'
        )
    );

$json_data = json_encode($data);

$url = 'https://'.$mailchimp_datacenter.'api.mailchimp.com/3.0/lists/'.$mailchimp_list_id.'/members/' . $userid . '/tags';


$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json',
    'Authorization: Basic '.$auth));
curl_setopt($ch, CURLOPT_USERAGENT, 'PHP-MCAPI/2.0');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
if ($displaytaglist!="") {
    curl_setopt($ch, CURLOPT_POST, true);   
    curl_setopt($ch, CURLOPT_POSTFIELDS, $json_data);
}
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
$result = curl_exec($ch);

你知道是什么问题吗？我有这个回报：

stdClass Object
(
    [type] => http://developer.mailchimp.com/documentation/mailchimp/guides/error-glossary/
    [title] => Invalid Resource
    [status] => 400
    [detail] => Expected argument of type "array or Traversable and ArrayAccess", "string" given
    [instance] => XXXXX-XXXXX-XXXXX
)

Answer 1

我必须使用嵌套数组才能使标签工作：

$data = array(
  'tags' => array(
    array(
      'name' => $tagname,
      'status' => 'active' 
    )
  )
);

如果没有嵌套数组( array('name' => $tagname,'status' => 'active' ) ) MailChimp 返回以下错误消息：

'无效资源'，400，'类型为“数组或可遍历和ArrayAccess”的预期参数，给出了“字符串”

可以通过这种方式设置多个标签：

$tagname1 = "TAG_NAME_1";    
$tagname2 = "TAG_NAME_2"

$data = array(    
  'tags' => array(    
    array(    
      'name' => $tagname1,    
      'status' => 'active'     
    ),    
    array(    
      'name' => $tagname2,    
      'status' => 'active'     
    )    
  )    
);

说：

$tagname1 = "TAG_NAME_1";
$tagname2 = "TAG_NAME_2";

这将给出 $data 变量的以下 JSON 表示：

{"tags":[{"name":"TAG_NAME_1","status":"active"},{"name":"TAG_NAME_2","status":"active"}]}

Answer 2

// Tags should be passed as multidimensional array. Replace your data variable with this and it will work. No need to pass email & apikey in data variable. Tested.

$data = array(
    'tags' => array(
        array(
            'name' => $tag,
            'status' => 'active'
        )
    )
);
