WooCommerce MailChimp subscription failed: MMERGE3

Check your merge fields in MailChimp. The plugins assumes the MailChimp defaults of EMAIL, FNAME and LNAME. It appears you may have a merge field named MMERGE3 setup in MailChimp and it might be set as required.

Hello, I have same problem.

My MailChimp value is NOT FNAME and LNAME, but simply NAME. It is a text value and it is required. I treat as one value, not two.

Is there a way to map this and make this plugin work? Can you alter what gets passed?

My error is: “WooCommerce MailChimp subscription failed: MMERGE3 must be provided – Please enter a value (250)”

My MailChimp account wants NAME to be passed as MMERGE3.

thx

You can hook into the ss_wc_mailchimp_subscribe_merge_vars action filter to override the merge fields sent to MailChimp. See below.

// tie into the WooCommerce MailChimp 'ss_wc_mailchimp_subscribe_merge_vars' action filter to modify the MailChimp merge vars
function ss_wc_modify_mailchimp_merge_fields( $merge_vars, $order_id ) {
    // By default $merge_vars will look like array( 'FNAME' => 'Joe', 'LNAME' => 'Smith', 'EMAIL' => '[email protected]' );

    // let's add a new 'MMERGE3' merge field for 'NAME'
    $merge_vars['MMERGE3'] = $merge_vars['FNAME'] . ' ' . $merge_vars['LNAME'];

    // Now let's remove the 'FNAME' and 'LNAME' merge fields
    unset($merge_vars['FNAME']);
    unset($merge_vars['LNAME']);

    return $merge_vars;
}
add_filter( 'ss_wc_mailchimp_subscribe_merge_vars' , 'ss_wc_modify_mailchimp_merge_fields', 10 , 2 );

What would it cost to have you implement this fix? Thanks!

Please let me know if you are still in need of this fix.
