How to get custom shipping module costs through to checkout?

[s_mack]

The wiki seems to be vacant on this issue from what I can find, but if there is a guide... please provide a link.

I'm trying to make a custom shipping module. I started with various built in one but couldn't figure out how to get multiple shipping options. Then I emulated some of the add-on modules that have that (DHL, UPS) and managed to get multiple options to show... but choosing an option and clicking continue results in a shipping cost of zero, even though they were displayed correctly in the shipping page.

What's the trick?

Here's an example quote function.

        function quote($method = '') {
            global $order, $shipping_weight, $shipping_num_boxes, $total_weight, $boxcount, $handling_cp, $cart;
             
            $methods = array();
            for ($x = 0; $x <= 10; $x++) {
              $methods[] = array('id' => 'ID' . $x,
                     'title' => 'Title' . $x,
                     'cost' => $x,
                     'insurance' => $x*.1,
                    );
            }
                $this->quotes = array('id' => $this->code,
                    'module' => MODULE_SHIPPING_SFC_TEXT_TITLE,
                    'methods' => $methods);
                if ($this->tax_class > 0) {
                    $this->quotes['tax'] = zen_get_tax_rate($this->tax_class, $order->delivery['country']['id'], $order->delivery['zone_id']);
                }

            return $this->quotes;
        }

It works and I'm shown 10 options priced $1 to $10... but choosing any shows zero next page.

Thanks.

I see through var dumps that the info is handled correctly on the shipping page but the session variable that gets passed onto the payments screen always has the first element's information for "cost" and "title" (ID is correct). Can't for the life of me figure out why that is.

I'm so confused. When I look at ANY shipping module, they all start with:

  function quote($method = '') {

Yet none of them actually make use of a variable "$method"???

Weirdness. Is ZC 1.5.4 not capable of dealing with multi-method quotes from a provider?? I tried testing UPS and USPS but in both cases I instantly get a "contact your store" error instead of any results. I can't figure out what's going on.

Again, $methods "ID" is being passed on, but title and cost are both as if option 1 was always selected.

ANY help?

For USPS are you using the latest version??

You can go HERE put something in the cart and Estimate Shipping Costs
You will see several USPS quotes

I actually meant DHL, not USPS. I can't use USPS as I'm not a US based store.

But I'm not trying to use any existing module. I'm trying to create my own and attempting to emulate existing ones since there's no documentation at all for this task that I can find. My problem was described... how to get multiple products from a shipping module to continue through to steps 2+?

Seriously, what am I doing wrong? This is about as simple as it gets:

        function quote($method = '') {
//            global $order, $shipping_weight, $shipping_num_boxes, $total_weight, $boxcount, $handling_cp, $cart;

            $methods = array();
            $methods[] = array('id' => 'standard', 'title' => 'Standard', 'cost' => 2.32);
            $methods[] = array('id' => 'express', 'title' => 'Express', 'cost' => 18.00);
      $this->quotes = array('id' => $this->code,
                            'module' => $this->title);
          
            $this->quotes['methods'] = $methods;

                if ($this->tax_class > 0) {
                    $this->quotes['tax'] = zen_get_tax_rate($this->tax_class, $order->delivery['country']['id'], $order->delivery['zone_id']);
                }
            return $this->quotes;
        }

Judging by the other modules... that SHOULD work! But it doesn't. On shipping page I see "Standard" and "Basic" with their associated costs and if I select "Express" and click continue... the "Standard" rate is shown, even though the "Express" ID is clearly in $_SESSION['shipping']

This is based on the above discussion and limited use of the shipping options. Sounds like you have multiple methods, but when wantiing the quote for a single previously chosen method you want the related data to be returned..

I think you hinted at it already, but I don't see anything that uses the $method variable within the quote...

Did you create shipping and language files for your custom shipping module?

Neither do I... in any of the existing modules. I looked at the UPS and DHL modules, which surely return multiple options although I can't test because neither work for me, and neither make use of that variable. Seeing as there's no documentation (which is amazing in itself considering how old this software is), what can I do other than emulate other modules?

*IF* your hint is suggesting that I'm supposed to return a single value when that variable is used... where's the comments or docs that makes that clear and what that variable even is or what exactly is to be returned? Leaving the user to 12 hours of guess-and-check kinda stinks.

PLEASE tell me I just missed some info somewhere. I did finally figure it out last night on my own... I come here this morning and still nobody's actually provided an answer. Your hint only means anything because I figured it out on my own. Had I not, I wouldn't have even caught what you were getting at.

Your question that I attempted to answer

You have apparently solved your original issue for this yourself
I might suggest that you be more complete in phrasing your questions in the future
