Can't get array. The controller gets only 1 parametr.

Form in view:

> > \<div class="field"\> &nbsp;&nbsp;&nbsp;&nbsp;\<% Categor.all.each do |cat| %\> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;\<%= check\_box\_tag(:prodcat,cat.id) %\> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;\<%= label\_tag(:prodcat, cat.title) %\>\<br\> &nbsp;&nbsp;&nbsp;&nbsp;\<% end %\> \</div\>

Controller:

> > params[:prodcat].each do |cat| &nbsp;&nbsp;&nbsp;@pc=Prodcat.new(@product.id,cat) &nbsp;&nbsp;&nbsp;@pc.save end

How i can get array?

In view...

\<%= check\_box\_tag('prodcat', cat.id) %\>

Would be one way...
