Mailchimp integration, custom merge fields

Hi, I’m using a silent subscription hack to silently subscribe some users to Mailchimp on registration. I’m also using a merge array filter to pass on custom fields (such as birthday and other details) to mailchimp – http://www.primothemes.com/forums/viewtopic.php?p=20994#p20994 .
I’m having trouble retrieving the custom s2member registration fields. Here is my s2-hacks.php code:

add_filter("ws_plugin__s2member_mailchimp_double_optin", "__return_false");
add_filter('ws_plugin__s2member_mailchimp_merge_array', 'mailchimp_merge', 10, 2);
function mailchimp_merge($merge, $vars)
    {
// $merge /* Array of existing MERGE fields that s2Member passes by default. */
// $vars /* Array of defined variables in the scope/context of this Filter. */

        //print_r($vars); // Lots of good stuff in this array.
		$user_id = $vars['user_id'];
		$cfields = get_user_option('wp_s2member_custom_fields', $user_id);
		

	return array_merge($merge, array('USER_ID' => $user_id, 'MERGE3' => $cfields['province'], 'MERGE4' => $cfields['two'], 'MERGE5' => date("m/d/Y")));

    }

Looking at mailchimp log, MERGE3 and MERGE4 come through as null.
Thanks,

If they’re coming through as null, I recommend double-checking that province and two are actually the names of the Custom Registration Fields. Could it also be that someone left those fields empty when they submitted the form?

Don’t think so, it’s me filling it out.

Any ideas?

if you [hilite code]print_r($cfields)[/hilite], are [hilite mono]province[/hilite] and [hilite mono]two[/hilite] there?

Hi where do I check the output of print_r? Thanks

It’d be shown in the browser… but if you don’t see it there, then you could save it to a file and look there. http://stackoverflow.com/questions/2628798/print-array-to-a-file

Hi, thanks for the help. Had to change the get_user_option line by replacing

$cfields = get_user_option('wp_s2member_custom_fields', $user_id);

with

$cfields = get_user_option('wpsal_s2member_custom_fields', $user_id);

The “sal” I added on is specific to our site. Now it works fine :-)

Ah, got it. Glad you found the problem! Thanks for the update. :)
