Where is large package weight defined?

[woodpecker]

Hi folks,

 

I see the packing weight calculation changes between small/medium and large packages but how do I set the breakpoint at which a package becomes large?

 

Thanks,

Andy.

I believe

It is in Admin under Configuration-Shipping/Packaging

[woodpecker]

I can't seem to find it there, I have options for tare weight and the % to set for large packages. The trouble I have is that osc is treating most of my packages as large when I don't want it to. I need to change the weight at which it decides a package is large.

 

Can someone please help????

 

Thanks,

Andy.

are you using a table rate for shipping

Hi,

 

I'm using zone based shipping but at the moment everything is getting the 10% extra weight added on because OSC thinks its a large parcel. I really want OSC to think most things are small and I'm trying to find out how to change the number. I presume there must be something that says if weight>x then parcel = large. I want to change x.

 

Thanks,

Andy.

The answer is is the second post.

The answer is is the second post.

Is it? In Admin -> Configuration -> Shipping/Packaging, the only option I can see for larger packages is to assign a percentage increase. When I was testing, that just seemed to add the percentage assigned to the total shipping weight on orders that had multiple products.

 

Somewhere in the code there must be something telling the cart to make a package 'large' based on some predetermined equation, but I've not been able to find it. I checked:

 

/catalog/includes/classes/shipping.php

/catalog/includes/classes/order_total.php

/catalog/includes/classes/order.php

/catalog/includes/configure.php

 

Admittedly, I am by no means a PHP expert (though I have managed to do a fair bit of modification to my cart, both through contrib's and my own manipulation), but I couldn't find anything in any of the above files that seemed to relate to the 'large' package weight.

 

Still searching...

Okay, a bit more investigation led me to this code in /catalog/includes/classes/shipping.php:

 

        if (SHIPPING_BOX_WEIGHT >= $shipping_weight*SHIPPING_BOX_PADDING/100) {
         $shipping_weight = $shipping_weight+SHIPPING_BOX_WEIGHT;
       } else {
         $shipping_weight = $shipping_weight + ($shipping_weight*SHIPPING_BOX_PADDING/100);
       }

 

The 'SHIPPING_BOX_PADDING' appears to be what is used to calculate the 'large' package weight. 'SHIPPING_BOX_WEIGHT' is the package tare rate set in the store config. I'm still not sure what this formula is saying, so I haven't quite figured out how to tie it all together. Anyone?

 

Thanks,

woops. premature submitculation there.

 

Basically, for the example I posted above, Anything below 5 lbs, the calcualted weight is always added the weight of the tare weight.

 

At 5 lbs and above, the tare weight is ignored. Instead of adding the tare weight to the actual weight of the products, 10% of the actual weight is added.

 

If you know a bit of Excel, you can use this formula to calculate the logic

 

=IF(shipping_box_weight>=A6*shipping_box_padding,A6+shipping_box_weight,A6+(A6*shipping_box_padding))

 

Email me if you want the excel file.

I beleive it translates into this: (assuming percent increase is set to 10%)

 

If tare weight is equal to or greater than 10% of item weight,

shipping weight = item weight + tare weight.

 

If tare weight is less than 10% of item weight,

shipping weight = item weight + 10% of item weight
