Customized shipping modules not working after upgrade

[BlackOrchidCouture]

Hello. So a while back Ajeh patiently helped me customize my USPS and flat rate module files so that if a certain product were in my cart a flat fee would be added in addition to any other shipping fee for the regular products, and it was working out.

A few months ago I upgraded to 1.3.9h, and I've just gotten around to testing out the checkout process, and now if I have one of these special products in the cart that would trigger the added flat rate, it just goes to a blank page and shows the paragraph I had written in to explain the flat fee. There's no way to continue, so no way to check out. I'm attaching a screen shot of what it looks like. If I remove this product and just have regular USPS triggered, it works as it should, it calculates the shipping charge by weight and there are no errors in the checkout process.

I looked at my debug logs and it says this:

[22-May-2011 14:27:01] PHP Warning: Cannot modify header information - headers already sent by (output started at ....../store/includes/modules/shipping/usps.php:276) in ..../store/includes/functions/functions_general.php on line 45

Here is line 276 in usps.php, it is part of the customized code:

global $cart;

    //check if manufacturer alchemy is in cart 
      if ((IS_ADMIN_FLAG == false && $_SESSION['cart']->in_cart_check('manufacturers_id','1') > 0)); {
        $manufacturer_alchemy = $_SESSION['cart']->in_cart_check('manufacturers_id','1');
  
        $drop_ship_extra_charge = $manufacturer_alchemy;
      }  
   // charge dropship fee for alchemy 
      if ($drop_ship_extra_charge > 0) { 
        $cat_extra_charge = 5; 
        echo '<br /><font color="#660000" size="2"><em>A flat $5 shipping fee to cover all Alchemy items in your cart has been added to the shipping quote below. Please note that Alchemy products ordered from Black Orchid Couture can only be shipped to addresses in the United States. All Alchemy products are special ordered from England and will be mailed to you separate from any other items in your order, and will take between 2-3 weeks to be delivered.</em></font>';
      } else {
        $cat_extra_charge = 0;
      }

        $methods = array();
        $size = sizeof($uspsQuote);
        for ($i=0; $i<$size; $i++) {
          list($type, $cost) = each($uspsQuote[$i]); 

The question is, did some part of the usps.php code change that would interfere with the custom code above? Or maybe I made a mistake in transfering it to the new code? I'm just not sure how to interpret the error log, I looked at the other file (functions_general.php) and there is no custom code in there. I just don't know how to fix this other than installing the usps.php fresh and starting over trying to figure out how to customize it.

Thanks for any help!!!!

Insure that in the upgrade, that you checked for any files that had new versions - especially those that you edited/cloned for this

Blank page issues in general

[Ajeh]

Take out the echo that you have in there ... does it work now?

[BlackOrchidCouture]

Ok, I took out the echo and it's now going to the regular checkout page, so that fixed going to the blank page, thanks! BUT, it's not applying the $5.00 flat shipping fee on top of the regulara USPS fee (I put a regular item and a special item).

The thing is this used to work, it would apply the $5.00 flat fee and also include my echoed paragraph. But this is better than a complete error!

Why do you not just apply in the shipping module setup a $5.00
Handling Fee

All using stock code

That's an intersting idea on how to do it, but I'd have to set it up so that the $5.00 handling fee only got charged if there were any products from this particular category/manufacturer. I'm thinking customizing the code is the only way to do this? But I haven't ever looked at how to add a handling fee. Would this be in the USPS module?

Did you clone the USPS module for the specific cat thing??

Then handling fee would be set in that cloned module setup in the admin

Depending on the age of what you upgraded from...

You might need to merge your customizations into the most recent USPS module

[BlackOrchidCouture]

I didn't clone any shipping module, I customized both the flat rate and the USPS files to look for the product category and also look for weight, as I set these products to zero weight. So if the whole cart is zero weight, then it means that only this category is in the cart, so only the flat rate gets activated. If there is any weight in the cart, it looks for whether or not this one product category is in the cart, if not then only the USPS module is activated. If the cart is mixed, it uses both.

In terms of the latest USPS module, I had updated it when Ajeh put out the latest one in January, I merged the custom code in with the updated code.

I will have to explore cloning shipping modules more as well as adding a handling fee. If I can add a $5.00 handling fee just if any products from this one category are in the cart, I could just use the USPS module and it should work. I will look more closely at all this tomorrow....

Thanks!

What are you doing with the:
$cat_extra_charge

in the rest of the code?

[BlackOrchidCouture]

I will show you all the custom code on the USPS and flat files. Now that I look at it, that is the only place that $cat_extra_charge shows up.

Towards the beginning of usps.php:

global $cart;

// check cart weight
  if (IS_ADMIN_FLAG == false) {  
    $chk_products_weight = $_SESSION['cart']->show_weight();
  }


// enable if total product weight is more than zero
  if (IS_ADMIN_FLAG == false && $chk_products_weight > 0) {
    // show USPS
    $this->enabled = true;
  } else {
    $this->enabled = false;
  } 

Later in usps.php, I'll inlude some of the code that comes after so you can see where it is:

global $cart;

    //check if manufacturer alchemy is in cart 
      if ((IS_ADMIN_FLAG == false && $_SESSION['cart']->in_cart_check('manufacturers_id','1') > 0)); {
        $manufacturer_alchemy = $_SESSION['cart']->in_cart_check('manufacturers_id','1');
  
        $drop_ship_extra_charge = $manufacturer_alchemy;
      }  
   // charge dropship fee for alchemy 
      if ($drop_ship_extra_charge > 0) { 
        $cat_extra_charge = 5; 
        } else {
        $cat_extra_charge = 0;
      }

        $methods = array();
        $size = sizeof($uspsQuote);
        for ($i=0; $i<$size; $i++) {
          list($type, $cost) = each($uspsQuote[$i]);

// fix new trademark and reg 01-02-2011
//$type = str_replace('&amp;lt;sup&amp;gt;&amp;amp;reg;&amp;lt;/sup&amp;gt;', '<sup>&reg;</sup>', $type);
//$type = str_replace('&amp;lt;sup&amp;gt;&amp;amp;trade;&amp;lt;/sup&amp;gt;', '<sup>&trade;</sup>', $type); 

In flat.php:

global $cart;

// check total cart weight
  if (IS_ADMIN_FLAG == false) {  
    $chk_products_weight = $_SESSION['cart']->show_weight();
  }

// enable if total product weight is 0 
  if (IS_ADMIN_FLAG == false && $chk_products_weight == 0) {
    // show FLAT
    $this->enabled = true;
  } else {
    // hide FLAT
    $this->enabled = false;
  }
