shopping cart display

I am trying to add the products weight and free shipping(if is free shipping) to shopping cart page. In the box beneath the products name and price and before the attributes listings. I am using zencart 1.51.
I need help with how to get the weight and if free shipping to show properly in the shopping cart page, tpl_shopping_cart_deafult file. I either get everything listed as free shipping or nothing listed as free shipping. I also have not been able to get the weight to appear at all. I have tried adding coding to modules page header which did not seem to help. Any suggestions of what to try next would be greatly appreciated.
What I am trying to get is the product name, cost, weight and free shipping then the attributes broken down with cost and weight to show under each product.
Sample of what I am trying to achieve:

Doctor Decorative Throw
[click to edit]
Decorative Throw - $51.99
[Free Shipping] - [ lbs.]
Additional Matching Items
•Tote Bag - [$35.00][2 lbs.]
Throw Personalization
•Dr. Lana Smith - [$0.00][0 lbs.]
Tote Bag Personalization
•Dr. Lana Smith - [$0.00][0 lbs.]

Grapes Stained Glass Panel
Grapes Stained Glass Panel - $102.95
[Free Shipping] - [ lbs.]

The 2nd item is not free shipping.
I also have not taken the time to work on getting the Calulated Charges for the text to work yet.
Please help with suggestions on how to proceed.
Thanks

On the product_info Attributes already will show if there is weight on them ...

What are you trying to do that is different from how it already works by default? :lookaroun

I am adding the base weight and price of the item. The attributes weight and price(except for the text price total) I programmed to show for each attribute. I am having trouble with getting the products weight to show.

I did not catch that you said product info page. I am trying to edit the shopping cart page in the cart box with a breakdown of the item(s) they are purchasing. The item, price,weight,free shipping if applicable,attributes and their price & weight.

You could customize the files:
/includes/modules/pages/shopping_cart/header_php.php

      $attributes = "SELECT popt.products_options_name, poval.products_options_values_name, pa.options_values_price, pa.price_prefix, pa.attributes_discounted, pa.products_attributes_id, pa.products_attributes_weight_prefix, pa.products_attributes_weight

// bof: show attribute price in cart
      if ($attributes_values->fields['attributes_discounted'] == 1) {
        // apply product discount to attributes if discount is on
        //              $new_attributes_price = $products_options->fields['options_values_price'];
        $new_attributes_price = zen_get_attributes_price_final($attributes_values->fields["products_attributes_id"], 1, '', 'false');
        $new_attributes_price = zen_get_discount_calc((int)$products[$i]['id'], true, $new_attributes_price);
      } else {
        // discount is off do not apply
        $new_attributes_price = $attributes_values->fields['options_values_price'];
      }
      $attrArray[$option]['new_attributes_price'] = $new_attributes_price;
      $attrArray[$option]['products_attributes_weight_prefix'] = $attributes_values->fields['products_attributes_weight_prefix'];
      $attrArray[$option]['products_attributes_weight'] = $attributes_values->fields['products_attributes_weight'];
// eof: show attribute price in cart

/includes/templates/your_templates_dir/templates/tpl_shopping_cart_default.php

with:

<!-- ORIGINAL <li><?php echo $value['products_options_name'] . TEXT_OPTION_DIVIDER . nl2br($value['products_options_values_name']); ?></li> -->
<li><?php echo $value['products_options_name'] . TEXT_OPTION_DIVIDER . nl2br($value['products_options_values_name']) . ' [ ' . $value['price_prefix'] . $currencies->format($value['options_values_price']) . ' ] ' . $currencies->format($value['new_attributes_price'])  . ($value['products_attributes_weight'] > 0 ? ' [ ' . $value['products_attributes_weight_prefix'] . $value['products_attributes_weight'] . 'lbs ] ' : ''); ?></li>

I already have those values(except for the combined text charge-calculated letters charges). I am looking for the product (not attribute) weight and if item is listed as free shipping.

A quick way to get something from the tables:
products
produces_description

is to use the function zen_products_lookup ...

On the shopping_cart template, you could use:
zen_products_lookup($product['id'], 'products_weight')

to obtain the Product weight without the Attribute weight includes ...
