Hi,

I am getting the following error:

array_merge() [<a href='function.array-merge'>function.array-merge</a>]: Argument #2 is not an array in /home/afana/public_html/drupal5/modules/mimemail/mimemail.inc on line 106.

and this apparently related error:

array_merge() [<a href='function.array-merge'>function.array-merge</a>]: Argument #2 is not an array in /home/afana/public_html/drupal5/includes/common.inc on line 1955.

which references these lines in common.inc:

    $defaults['From'] = $defaults['Reply-To'] = $from;
  }
  $headers = array_merge($defaults, $headers);   <===== line 1955
  // Custom hook traversal to allow pass by reference

It seems that PHP is having issues with the $header variable.
These errors seem to have cropped up since my host server was upgraded to PHP 5.2.6 but that may or may not be related.

Which module is sending an email that causes this error?
Can you find out what the content of the Argument #2 is? The one reported in modules/mimemail/mimemail.inc on line 106. (use var_dump() to print the variable).

The most recent incidences of the error were triggered by the Paypal module (submodule of eCommerce) when it triggers an IPN transaction (IPN is a Paypal feature). There are no errors on the PayPal end though the e-mail that results is not properly mime encoded and the following content is inserted in the body without the proper header content lines being set:

This is a multi-part message in MIME format.

--ae4fc17f36426e885b07cdeb69503ada
Content-Type: multipart/alternative;
    boundary="e0947c2e6ee1ae0d7a48a9c9b3f4ff73"
Content-Disposition: inline
Content-Transfer-Encoding: 8bit

IF (big if) I placed the var_dumps at the right place in the mimemail module this what I got back (email addresses obscured):
array(1) { ["mail"]=> string(18) "axxxxx@xxxxx.com" } object(stdClass)#110 (24) { ["uid"]=> string(4) "1278" ["name"]=> string(9) "Test User" ["pass"]=> string(32) "ae2b1fca515949e5d54fb22b8ed95575" ["mail"]=> string(18) "axxxxx@xxxx.com" ["mode"]=> string(1) "0" ["sort"]=> string(1) "0" ["threshold"]=> string(1) "0" ["theme"]=> string(0) "" ["signature"]=> string(0) "" ["created"]=> string(10) "1208038831" ["access"]=> string(10) "1208039180" ["status"]=> string(1) "1" ["timezone"]=> string(6) "-14400" ["language"]=> string(0) "" ["picture"]=> string(0) "" ["init"]=> string(18) "axxx@xxxxxxxxx.com" ["data"]=> string(142) "a:5:{s:7:"display";s:1:"2";s:19:"mass_contact_optout";i:0;s:12:"current_date";s:10:"1202834503";s:10:"current_id";s:2:"11";s:7:"contact";i:1;}" ["login"]=> string(10) "1208039037" ["display"]=> string(1) "2" ["mass_contact_optout"]=> int(0) ["current_date"]=> string(10) "1202834503" ["current_id"]=> string(2) "11" ["contact"]=> int(1) ["roles"]=> array(1) { [2]=> string(18) "authenticated user" } }

I dumped these variables: 

  var_dump($edit);
  var_dump($user);

May or may not help but I have also tied it to this error:
Invalid argument supplied for foreach() in /home/afana/public_html/drupal5/modules/mimemail/mimemail.inc on line 21.

Title: PHP error: Array.merge » faulty header definition of paypal debug email
Project: Mime Mail » e-Commerce
Version: 5.x-1.x-dev » 5.x-3.x-dev
Component: Code » paypal
Category: support » bug

It is the $headers variable in mimemail_rfc_headers() which causes the problem. It should be an array and is a string.

I have found an error in the 5.3 version of the ecommerce paypal module.
The header definition on line 419 of paypal.module is wrong:

<?php
    $headers    = "From: $from\nReply-to: $from\nX-Mailer: PHP\nReturn-path: $from\nErrors-to: $from";
?>

And should be (not tested):

<?php
    $headers    = array('From' => $from, 'Reply-to' => $from, 'X-Mailer' => 'PHP', 'Return-path' => $from, 'Errors-to' => $from);
?>

Transfering this issue to e-commerce module issue queue.

Is any work on going with v3.4 any longer? Will this bug be fixed?

Try the latest version of ec 5.x.3.x-dev and let me know the results.

Thanks,

Installed the 5.x.3.x-dev release and so far, so good. The errors haven't returned.

Thanks for giving this some attention.
