shipping tied to attribute

[andy_d]

I am trying to set up a shipping schema for artwork as follows:

one to seven prints: X dollars.
framed print: x dollars per framed print.

Is there any way I can tie this schema to the attributes?

Thank you.

What Shipping Module(s) are you currently using?

Are you wanting to just add to the shipping cost of your Shipping Module(s) based on the Attributes?

I am a true "newbie." Not sure which module I should select. Yes, I would. Thank you.

It depends on the shipping module you want to use such as UPS, USPS, FedEx or Zone Rates etc.

But something could be worked out to add additional charges to based on the Attributes ...

Now you need to decide how you want to price your shipping charges, then something could be worked into the code ...

[andy_d]

I figured the code angle would be the best. Where can I find the code for the shipping and product modules?
Thank you.

It would really be of help to know what shipping module(s) you want to use to manage your shipping ...

Are you wanting to use something like USPS? Or Flat rate? Or Item Rate?

Have you an URL to your site that we could perhaps peek at to get a feel for how your products are set up?

Would like to use table for prints (up to 7 prints for $8, 8 to 14 for $16, etc.) and not sure what to use for the framed prints ($22 per framed print).
Again, thanks

So if I have:
7 prints and 1 Framed Print the cost would be $8.00 + $22.00 = $30.00
7 prints and 2 Framed Print the cost would be $8.00 + 2 x $22.00 = $52.00
7 prints and 3 Framed Print the cost would be $8.00 + 3 x $22.00 = $74.00

Correct?

And Frame Prints are always Options Name ID (options_id) 1 and Options Values ID (options_values_id) 1 correct?

If this is what you are wanting, you could add the code in RED to the bottom of the file:
/includes/classes/shopping_cart.php

     return $new_qty;
  }
// bof: change $total_count for options_id/options_values_id combo
/**
 * calculate the number of items in a cart based on an attribute option_id and option_values_id combo
 * USAGE:  $chk_attrib_1_16 = $this->in_cart_check_attrib_quantity(1, 16);
 * USAGE:  $chk_attrib_1_16 = $_SESSION['cart']->in_cart_check_attrib_quantity(1, 16);
 *
 * @param float $check_qty
 * @param int $check_option_id
 * @param int $check_option_values_id
 * @param string $message
 */
  function in_cart_check_attrib_quantity($check_option_id, $check_option_values_id) {
    // if nothing is in cart return 0
    if (!is_array($this->contents)) return 0;

    // compute total quantity for match
    $in_cart_check_qty = 0;
    // get products in cart to check
    $chk_products = $this->get_products();
    for ($i=0, $n=sizeof($chk_products); $i<$n; $i++) {
      if (is_array($chk_products[$i]['attributes'])) {
        foreach ($chk_products[$i]['attributes'] as $option => $value) {
          if ($option == $check_option_id && $value == $check_option_values_id) {
  //          echo 'Attribute FOUND FOR $option: ' . $option . ' $value: ' . $value . ' quantity: ' . $chk_products[$i]['quantity'] . '<br><br>';
            $in_cart_check_qty += $chk_products[$i]['quantity'];
          }
        }
      }
    }
    return $in_cart_check_qty;
  }
// eof: change $total_count for options_id/options_values_id combo
}

Then customize your file:
/includes/modules/shipping/table.php

with the code in RED:

  function quote($method = '') {
    global $order, $shipping_weight, $shipping_num_boxes, $total_count;

// bof: change $total_count for options_id/options_values_id combo
    $chk_options_id = 20;
    $chk_options_values_id = 72;
    $additional_shipping = 22.00;
    $reduce_count = $_SESSION['cart']->in_cart_check_attrib_quantity($chk_options_id, $chk_options_values_id);
    $total_count = $total_count - $reduce_count;
// eof: change $total_count for options_id/options_values_id combo

    // shipping adjustment
    switch (MODULE_SHIPPING_TABLE_MODE) {

// bof: change $total_count for options_id/options_values_id combo
    $additional_shipping_charge = $reduce_count * $additional_shipping;

    $this->quotes = array('id' => $this->code,
    'module' => MODULE_SHIPPING_TABLE_TEXT_TITLE . $show_box_weight,
    'methods' => array(array('id' => $this->code,
    'title' => MODULE_SHIPPING_TABLE_TEXT_WAY,
    'cost' => $shipping + $additional_shipping_charge + (MODULE_SHIPPING_TABLE_HANDLING_METHOD == 'Box' ? MODULE_SHIPPING_TABLE_HANDLING * $shipping_num_boxes : MODULE_SHIPPING_TABLE_HANDLING) ) ));
// eof: change $total_count for options_id/options_values_id combo

    if ($this->tax_class > 0) {

And this will now charge the count for Products based on the number of regular Products that are Prints using the Table Rate table settings and for the Framed Prints it will charge $22.00 each ...

NOTE: change the values on:

    $chk_options_id = 20;
    $chk_options_values_id = 72;

To match your options_id value and the options_values_id value ...

I have a similar query.

I am using Zen version 1.3.9 with Books module.
The shipping module is Flat Rate.
I want to offer free shipping on the entire order when a particular attribute is selected.
Could you please help.
Thanks in advance.
