Here is one way to do it, maybe not the most efficient but it works.  It
puts all items in the cart even if they have quantity=0, so you can use
[item-list] to show the customer all the items available.  You would need
to put it at the top of ord/basket.html, you can see an example at:
   http://www.campandschooloutfitter.com/cgi-bin/brodys/ord/campwear

It uses a data field called "number" to control the sort order of the
items as they appear in the basket, but you could do that a variety of
other ways.


[perl arg="carts" interpolate=1]

   # get a list of all product codes:
   my @codes = qw(
         [tag each products][sort products:number:n][loop-code] [/tag] );

   if ( defined $Safe{'carts'}->{'main'} ) {
      # Save a copy of the cart, and empty out the real one:
      my $cart = $Safe{'carts'}->{'main'};
      $Safe{'carts'}->{'main'} = [];

      # If products already exists in cart, move it to main cart,
      # otherwise, add it to main cart with quantity 0:
      foreach my $code ( @codes ) {
         if ( $cart->[0] && $cart->[0]->{'code'} eq $code ) {
            push @{$Safe{'carts'}->{'main'}}, shift @{$cart};
         }
         else {
            push @{$Safe{'carts'}->{'main'}}, { 'code'     => $code,
                                                'quantity' => 0,
                                                'mv_ib'    => 'products' };
         }
      }
   }
   else {
      # No main cart, so create one and add all items with quantity 0:
      $Safe{'carts'}->{'main'} = [];
      foreach my $code ( @codes ) {
         push @{$Safe{'carts'}->{'main'}}, { 'code'     => $code,
                                             'quantity' => 0, 
                                             'mv_ib'    => 'products' };
      }
   }
   '';
[/perl]
