Rails - Jun 2010 - Q: Rails 3 Multiselect input param

In Rails 3, I have a multi-select form control (fig. 1). When I select
more than 1 value, Firefox sends both values (fig. 2). But only the last
value gets sent as a input value to my controller (fig. 3). How do I get
all those values passed on to my controller?


      <form action="html_items/search" method="post" >

        <!-- Criteria -->
        <div style="float:none;">
          <label>Content Provider </label>
          <select multiple id="content_provider"
name="content_provider">
            <option value="FLR">Flare</option>
            <option value="SLDT">Slashdot</option>
          </select>
        </div>

        <input type="submit" value="Search" />

      </form>

content_provider  FLR
content_provider  SLDT

PARAMs[{"content_provider"=>"SLDT",

"action"=>"search"}]
