<%=submit_tag "Display Results", :class => "submit"%>
<%end%>
This enables me to select a single product from a drop down menu of
products.
It then saves this product in query object.
I want to be able to select multiple products and for them to be held as
an array in query.
Is this possible??

Add ':multiple=>true' to the options hash for the select

I haven't got it to work quite yet.
When I select multiple products, I was hoping they would be sent as an
array to the query object.
But:
When I select multiple products, only 1 product (the first one) gets
sent.
Do you know how to send them as an array?

Give the control a name like :name=>'products'
put that in the second hash with the :multiple=>true

Chris, here is something I have:
FORM:
<p>
<label for="categories">Categories</label><br />
<select id="categories" name="categories" multiple="multiple"
size="10" style="width: 250px;">
<%= options_from_collection_for_select(@all_categories,
:id, :long_name,
@selected) %>
</select>
</p>
CONTROLLER:
def create
@photo = Photo.new(params[:photo])
@photo.categories = Category.find(params[:categories]) if
params[:categories]
if @photo.save
flash[:notice] = 'Photo was successfully created.'
redirect_to :action => 'list'
else
@all_categories = Category.find(:all, :order => 'name')
render :action => 'new'
end
end
Hope that helps some.
