WordpressMU doesn't seem to work

I have the same problem... I have Drupal 5 and the latest snapshot of the Importer. I have downloaded the contents of a relatively small and simple Wordpress blog, try to import, and this is what I get:

error php 11/17/2008 - 20:48 in_array() [. admin
error php 11/17/2008 - 20:48 Invalid argument supplied for foreach() in ... admin
error php 11/17/2008 - 20:48 Invalid argument supplied for foreach() in ... admin

Has WP updated their XML schema? Or do I have something configured wrong?

The attached path fixes two things:

When exporting from MU $wordpress['categories'] is not set, and then wordpress_import_import_categories() does not return anything (WTF?) which causes wordpress_import_import_blog() to fail (you try to merge an array and NULL). The fix is trivial: at the end of function wordpress_import_import_categories(), after at the end of the function add this code:

  // diego - $wordpress['categories']) is not an array
    return array(
      'categories_map' => null,
      'categories_vocabulary' => null
      );

On wordpress, the comments are displayed from the latest to the newest. After import on Drupal I see the newest comments on the top, so I had to reverse the order of those comments. Inside wordpress_import_post() after the ksort() I added this line:

  // diego - messages should be sorted in reverse order
  $drupal_comment = array_reverse($drupal_comment);

I did a few tests on my local setup and it seems to work, so I attach here a patch against version 6.x-1.0 of the module, people using drupal5 you can always update to drupal6 or patch manually ;-)

I will integrate the code for the categories as soon as possible.

However, note that the change you made for ordering the comments may break the thread hierarchy. A better solution would be to choose the order that you want in the "Default display order" section of the content type form in Drupal.

Fixed in branches DRUPAL-5 and DRUPAL-6--1
