Support for Drupal 7 is ending on 5 January 2025—it’s time to migrate to Drupal 10! Learn about the many benefits of Drupal 10 and find migration tools in our resource center.As I promised in a forum post, my port to D6 is fully working, integrating a couple of patchs for correcting for IE7 and one or two bugs... I have it working great in a web Im working at so I post for you to check and test...

Just download the current version and overwrite the files with this versions...
I hope it'll be a valid starting point to make a official port to D6.

Comment #1
FrancewhoaThanks Hwangar. I'm testing the above port to D6. I'll get back to you with my results.
If someone else want to test Active Select port to D6 I have attached to this post the module Active Select for Drupal 6. This is an unofficial version base on the above patch from Hwangar.
How to install the module:
Comment #2
dydecker CreditAttribution: dydecker commentedThis sounds interesting.
Is Active Select still dependent on the category module or can it be used with any form?
Comment #3
FrancewhoaHwangar: Here are my testing results with Active Select (August 21, 2008) downloaded from this page. Using a Drupal 6.4 fresh intall and Devel module to quickly generate dummy taxonomy.
The installation works. I see the module in module admin page.
Active Select widget for module Content Taxonomy can't be tested yet. The widget is not yet ported to Drupal 6. I have open a task.
Hope this testing help.
The following is a note to myself for future reference. Before using Active Select I must run cron to update the taxonomy index. Otherwise taxonomy won't work properly.
Comment #4
that0n3guy CreditAttribution: that0n3guy commentedHow do you test this without the Active Select widget for module Content Taxonomy?
I have installed it and activated it on drupal 6.4, and I didn't get any errors... so that seems good.

Comment #6
Micha1111 CreditAttribution: Micha1111 commentedI tested the unofficial version above in combination with category_6.x-2.0-alpha4 and it works fine.
The containers and categories from category-module are saved as nodes, so I wonder, if there is an easy way to use "active select" for custom cck-nodereference-fields, because its the same stucture of data (simple nodes with relations) in my following example.
I have 4 content-types:
"Leagues": Number,Name
"Teams": Number,Name,inLeague (nodereference-field to content-type "Leagues")
"Players": Number,Name,inTeam (nodereference-field to content-type "Teams")
and the main-type "Pairs":
ofleague (nodereference-field -select- to content-type "Leagues")
team_home (nodereference-field -select- to content-type "Teams")
team_guest (nodereference-field -select- to content-type "Teams")
team_result (text-field)
player_home (multiselect nodereference-field to content-type "Players")
player_guest (multiselect nodereference-field to content-type "Players")
player_result (multiselect text-field)
At the moment, its difficult and not userfriendly to select 1 of 10 Leagues, 1 of 100 Teams and 1 of 1000 Players from select lists.
It would be easier, if the user, who adds a new pair, could at first choose a league
in the next select lists for team_home and team_guest only teams from the choosen league should be available
in the next select list for player_home only players from team_home should be available
in the next select list for player_guest only players from team_guest should be available
I can't use the category-module for this , because its not possible to use a category select-list-field twice in the same form like nodereference-fields.
I hope, there is somebody, who can support this feature.

that0n3guy CreditAttribution: that0n3guy commentedI posted my attempt to update the activemulti widget to D6 here: http://drupal.org/node/180687#comment-1103044
I based it all on what toitimhcm did (see #5 above) and ran it through coder module. As such, it doesnt seem to be referencing activeselect (just like toitimhcm's port) so if anyone can look at it really quick, that would be amazing!!
Comment #8
Hwangar CreditAttribution: Hwangar commentedHello guys,
after check the state of Hierarchical Select, and knowing that Wim is quite busy right now, the case is that I need to handle a huge hierarchy and cannot let users deal with the giant select (default implementation), so I decided recheck this module again and add a couple of features...
you can view it fully working here:
http://www.automotoocasion.com (the right searching block is based on the vocabulary)
I'm thinking about substituting the term-selector in node edits with this...
if anyone wants to add features, say now or shut up forever!!! :P
ok, I'll keep you informed
Juan Arias
Comment #9
that0n3guy CreditAttribution: that0n3guy commentedAwesome, thanks for showing your site to verify it works.
The only other features I'd go for are to have some content_taxonomy widgets working... especially this one: http://drupal.org/node/180687
I think its very close to working, it just needs someone who knows activeselect to look at it.

Comment #12
adf1969 CreditAttribution: adf1969 commentedI am trying to use the D6 port and am having the following issue (my code is at the end of this post):
My ActiveSelect works as the functionality is intended (as it relates to ActiveSelect. Fields load values with Ajax, fields can be selected, fields are "dependent" as expected).
Where the problem occurs is if I hit the "preview" or "save" buttons.
If I do that, I get the following error
The following is content.module:1234 :
I stepped through the entire form_builder() execution to see what was causing the error, and it appears that the following is the issue:
* When I turn "off" the ActiveSelect (and leave both CCK fields as plain old SELECT elements, the POST value for each of them is as follows:
* When I turn "on" the ActiveSelect, the POST values for each of the ActiveSelect elements is as follows:
I do not know why this is. I'm guessing it must have something to do with how ActiveSelect builds the actual "select" element on the client. I also noticed that the select "name" attribute is: "field_ref_pmproperty[nid][nid]" with ActiveSelect turned off, but is just: "field_ref_pmproperty" with ActiveSelect turned on.
I'm hoping that someone who understands FAPI and "widgets" can explain to me what the solution is.
I spent considerable time figuring out ActiveSelect and could really put it to use, then spent a bunch of time on this issue, and now I'm wondering if I should just skip using ActiveSelect entirely because I think solving this issue is a bit beyond me (I just don't understand how the POST value gets set in Drupal so am not even sure where to begin...this issue went from an ActiveSelect issue, into a Drupal core issue...which is out of my league...)
Here is my ActiveSelect implementation code:

jazzitup CreditAttribution: jazzitup commentedWhere can I download the most recent dev-version of this module for D6?
Comment #14
FrancewhoaHi madjoe,
Usually most recent dev-version of this module are available on this page under section 'activeselect HEAD' or section 'activeselect 6.x-1.x-dev':
http://drupal.org/node/49976/release
But there's no Drupal 6 section/branch setup yet. Only the module maintainer can open a new branch. Current module maintainer is Jaza http://drupal.org/user/15277
I have created a new task today asking to create a new branch: http://drupal.org/node/433022
In the meantime you could ask one of the above testers and or developers to post on this page a tarbal file or a zip file of their latest dev-version: http://drupal.org/node/298230
