Drupal 6 version of nr_autocomplete

Me neither!! I loved this module! It should totally be in CCK core. :)

Unless someone beats me to it, I probably won't be porting this to D6 until I suddenly run upon spare time or I need a D6 version for a client. Any contributions are always appreciated!

I needed this module to migrate my site to drupal 6 so i've attached a patch with the changes i've made.

Since cck's widget api has changed considerably there is a lot of new code in it, but where possible I borrowed from the main nodereference module.

So far with light testing it seems to work fine for me.

Hi all....I've attempted to implement the patch and I'm getting the following error:

warning: Invalid argument supplied for foreach() in /home/.../modules/nr_autocomplete/nr_autocomplete.module on line 228.

I have included the snippet below where the error is occurring. Any help would be greatly appreciated!

/**
 * Validate an autocomplete element.
 *
 * Remove the wrapper layer and set the right element's value.
 * This will move the nested value at 'field-name-0-nid-nid'
 * back to its original location, 'field-name-0-nid'.
 */
function nr_autocomplete_validate($element, &$form_state) {
  $field_name = $element['#field_name'];
  $type_name = $element['#type_name'];
  $field = content_fields($field_name, $type_name);
  $field_key  = $element['#columns'][0];
  $delta = $element['#delta'];
  $value = $element['#value'][$field_key];
  $values = array();
  $nid = NULL;
  $typed_titles = nr_autocomplete_parse_input($value);

Here is a re-rolled patch originally taken from #7. This patch only includes some minor code style fixes and cleanup.

Josh Benner has accepted me as a co-maintainer, and I've now committed a first stab at the 6.x branch. Checkout the code from CVS if the packaging script hasn't packed the release yet.
