POST /lists/list_id/members/sub_id/tags fails: This value should be of type iterable.

Mailchimp documentation:

https://mailchimp.com/developer/api/marketing/list-member-tags/add-or-remove-member-tags/

Code:

require("vendor/autoload.php");
use \DrewM\MailChimp\MailChimp;

MailChimp = new MailChimp(SCRUBBED);

// get subscriber hash
$subscriber_hash = md5(trim(strtolower($email)));

// update member's tags
$payload = [
	'tags' => [
		'name' => $tag,
		'status' => 'active'
	]
];

$upd = $MailChimp->post("lists/$list_id/members/$subscriber_hash/tags", $payload);

print_r($upd);

output:

Array ( [type] => http://developer.mailchimp.com/documentation/mailchimp/guides/error-glossary/ [title] => Invalid Resource [status] => 400 [detail] => The resource submitted could not be validated. For field-specific details, see the 'errors' array. [instance] => SCRUBBED [errors] => Array ( [0] => Array ( [field] => tags [message] => This value should be of type iterable. ) ) ) 

When I double wrap the tags (so it becomes an array of arrays), mailchimp complains that it should be a string. What does mailchimp actually want from me? Is this a bug?

[MayorUshanka]

When formatting it like this:

$MailChimp->post("lists/$list_id/members/$subscriber_hash/tags", [
	'tags' => ["
		\"name\": \"$tag\",
		\"status\":active
	"]
]);

It seems to be correctly formatted. Except mailschimp now complains that the field "name" is required - even though I clearly filled it in (I even tried hardcoding the $tag).

 [errors] => Array ( [0] => Array ( [field] => tags[0].name [message] => This value should not be blank. ) )

did you find a workaround for this ?

Also getting this issue

[rossjcooper]

I believe its due to https://github.com/drewm/mailchimp-api/blob/master/src/MailChimp.php#L390 when it is encoding the array of tags it is creating a JSON object instead.

[rossjcooper]

I've got it working by doing this

[
    'tags' => array_values($tags),
]

Which seems to trigger it to encode correctly 🤞

I tried this snippet but it didn't work. It creates the tag on mailchimp and the user doesn't receive the mail.

$added = $this->mailchimp_api->post('/lists/' . $this->list_id . '/members/' . $email_hash . '/tags', [
  "tags" => array_values([
    [
      "name" => "Influencer",
      "status" => "active"
    ]
  ])
  ]
);

How can I subscribe a user with a specific tag?

[MayorUshanka]

Ok, here is the code that seems to work for me

class MAILCUCK{ // MAILChimp Utilities Class Kernel
	private $MailChimp;
	private $debug;

	function __construct($debug = false){
		$this->MailChimp = new MailChimp('apikey');
		$this->debug = $debug;
	}

	function subscribe_or_add_tag($list_id, $email, $tag, $merge_fields=[]){

		// we have an audience (list).
		// we want to add an email with a tag to this list
		// if the email is already in the list, just append the tag
		// if not, subscribe along with the tag

		/*
		$merge_fields = [
			'FNAME' => "testF",
			'LNAME' => "testL",
			'ADDRESS' => "addr",
			'PHONE' => "testtel",
			'FULLNAME' => "TestF TestL"
		];
		*/

		$payload;

		if(empty($merge_fields)){
			$payload = [
				'email_address' => $email,
				'status'        => 'subscribed',
				'tags' => [$tag],
			];
		} else {
			$payload = [
				'email_address' => $email,
				'status'        => 'subscribed',
				'tags' => [$tag],
				'merge_fields' => $merge_fields,
			];
		}

		$result = $this->MailChimp->post("lists/$list_id/members", $payload);

		if ($this->debug){
			echo "Result: ".$result;
		}

		if ($result['title'] == "Member Exists"){

			if ($this->debug){
				echo "Member alreay exists, appending tag... ";
			}

			$subscriber_hash = md5(trim(strtolower($email)));

			$payload = [
				'tags'=>[
					[
						"name" => $tag,
						"status" => "active"
					]
				]
			];

			// update member's tags
			$upd = $this->MailChimp->post("lists/$list_id/members/$subscriber_hash/tags", $payload);

			if ($this->debug){
				print_r($upd);
			}
		} else {
			if ($this->debug){
				print_r($result);
			}
		}
	}
}
