Mailchimp subscription field: not loading Merge Fields or Lists

I have the same issue. I add a subscription field but it does not seem to see any of my lists.

I tried the latest 3.11 mail chimp in the hopes that would help, and also downloaded the older library 2.04 from Mailchimp. I have PHP 5.3.28, Drupal 7.32.

I add a subscription field to my user, and it all goes as expected except that the selector that is supposed to allow you to choose a list is greyed out. This is despite the fact I have a list connected, and a working subscription form that connects happily to Mailchimp.

I do have quite a fe modules on my site, and have tried disabling various ones but nothing seems to change this behavior.

Any tips would be greatly appreciated.

Same problem with Mailchimp 3.2. Get this "warning" in my log:

Warning: array_key_exists(): The first argument should be either a string or an integer in mailchimp_get_lists() (line 204 of /srv/bindings/532802b056d84e9484e7cc0d2f8b70b3/code/sites/all/modules/contrib/mailchimp/mailchimp.module).

Thanks for the bug report. Did you have any problems selecting a list when you created the subscription field (see attached screenshot) and have the available lists changed at all since creating the field?

Yes. The list select field was greyed out and did not allow me to select a list. However, if I go to the tab where you show lists etc my four available lists show up. So they are there but the subscribe field somehow does not see them.

ruscoe,

I have bypass the error modifying mailchimp_get_lists function in mailchimp.module. This is the relevant part of the function, where I haved added a check for the $id variable to be integer or string.

  // Filter by given ids:
  if (!empty($list_ids)) {
    $filtered_lists = array();
    foreach ($list_ids as $id) {
      if (is_numeric($id) || is_string($id)) {
        if (array_key_exists($id, $lists)) {
          $filtered_lists[$id] = $lists[$id];
        }
      }
    }
    return $filtered_lists;
  }
  else {
    return $lists;
  }

For example, when saving the newsletter field in /admin/config/people/accounts/fields/field_newsletter, the $id in the list is an array. Its happening in more places.

I don't know the filter intention here, and maybe this is not the correct solution... so I hope you can verify it.

I am receiving this same issue. I also get an error on the user entity: Mailchimp Lists field "field_newsletter_subscriptions" on user -> user has no EMAIL field configured, subscription actions cannot take place.

So as stated above: I cannot select a MailChimp List which I think this is in there on purpose...

function mailchimp_lists_form_field_ui_field_edit_form_alter(&$form, &$form_state, $form_id) {
  if ($form['#field']['type'] == 'mailchimp_lists_subscription') {
    // Disable the list selector on the instance config page:
    <strong>$form['field']['settings']['mc_list_id']['#disabled'] = TRUE;</strong>
    $form['field']['settings']['mc_list_id']['#description'] = t("To alter this list, use the 'Field Settings' tab");
    // Hide the cardinality setting:
    $form['field']['cardinality']['#default_value'] = 1;
    $form['field']['cardinality']['#access'] = FALSE;
    $form['#validate'][] = 'mailchimp_lists_form_field_ui_field_edit_form_validate';
  }
}

Disables the field on the field edit form. I could see the ability to allow "permissions" to take control of the list or something to that effect.

Hi! I removed 3 lines from mailchimp_lists/includes/mailchimp_lists.field.inc that was disabling the Mailchimp List field under subscription field's Global Settings. Once I removed these lines, the field is no longer greyed out. On my site, I was able to select the Mailchimp List I want, and then the list fields were synced with my site's fields. I'm using version 7.x-3.6 of the Mailchimp module.

I'm not sure whether there are some reasons for these lines to disable the field. Perhaps they were used for the earlier 2.x version, but no longer applicable for the 3.x version?

This might not be the best way to solve the issue, but I hope it helps in figuring out the final solution. Thanks!

We're going to be ending support for the 7.x-3.x branch due to the upcoming deprecation of the v2.0 MailChimp API. If you're still seeing this issue with the most recent release, please feel free to reopen for the 7.x-4.x branch.

Same issue for 7.x-4.x. Fix from #11 works.
