Tag multi select

[Константин Носов]

Hello. Could somebody help me with tag multiselec.

I need to show list of tags, and give visitor to chose some of them (for example tag1 & tag4)

After I shoul show list of pages that have both tags.

I found tag example on demo site, http://vosaocms.appspot.com/tags?tag=3870014 but I have no idea how to make it work with more than one tag.

Hi,

I listed some handy un-documented vosao velocity template commands
here: http://staging.vosao.org/designer/doc/templates (I should have
moved them somewhere else)

I'm not sure I fully understand, but could you not select all
documents matching a tag into a collection, then select all docs
matching another tag into either the same collection or another
collection?

Regards

You found great function!
$request.getParameter("count") - Access to parmeters in the HTTP
request eg "count"
using it I can pass tags via url.
There is a question how to pass variable list of tags using it...

Idea about two round filtering is good, but how can I create a collection?
$collection.add(tag)?

I'm not really a velocity expert and it's been a while since I've done
anything with it but I can try and offer some guidance.

Velocity supports java collections under the covers and you can create
them on declaration for example:
#set( $monkey.Say = ["Not", "my", "fault"] )

lots of the vosao velocity objects return collections, for example:
#set($myCollection = $service.tag.getTags("/page/url"))

Velocity then supports commands that can be carried out on the
collections, for example sorting:
#foreach($obj in $sorter.sort($objects, "name"))
$obj.name = $obj.ordinal
#end

General purpose tools:

I hope that's of some help
