Shipping by Wieght

Hi
I have setup 3 zones for my shipping

Zone 1
Zone 2
Zone 3

Each zone has a different base rate for shipping but includes the first 15kgs but now I need to add £xx.xx per kg above that original rate.

Is there an obvious clalculation Im missing here or do I really have to add each increment up to the most you could really imaine ie 100 kgs that would take masses of rules.

Thanks for any help or pointers.

Mike

you really only need 1 additional shipping rule to add the additional shipping.

lets say the base shipping is $20 for <= 15kg and $1 for each additional kg

Create the first rule using the trigger:
Subtotal for any column
Subtotal for column 'TotalWeight' is '>' a value of '0'

and use a flat rate calculation of 20.

For the second rule, use the trigger:
Subtotal for any column
Subtotal for column 'TotalWeight' is '>' a value of '15'



for the calculation, use:
Multiple Of Column Subtotal
Subtotal of column 'TotalWeight' 'times' '1' 'minus' '15'

Hi Jason
Thanks for the reply.

I tried that but could not get that to work and for some odd reason it show a different total on the cart page to the final confirm page.

My values are:

up to 15 kgs 26.95
Then 0.95 for every kg over

What also happens to part kg for example 15.1kg?

Thanks

Mike

Right tried again and just cannot seem to get it to come out with the correct result.

View_Cart gives a different shipping result to the confir, page details.

Either way it has not worked out the correct shipping.

Must admit a little lost with this one. I had previously tried your method before you said but to no avail.

Any other ideas appreciated.

Mike

Right theres seems to be an issue with the shipping calculations:

If using the calculation rules set out above but for each KG above the 15 you have an aditional cost of lets say 0.45p or 0.45c the shipping will not include the base charge as soon as you start working with £1 + then its ok but decimals seem to cause an issue with the calculation.

Mike

can you send a copy of the cart php file in the WA_eCart folder so I can examine the code, it works on my system regardless of the decimal or not.

Yes sure:

I have changed some things now though was going to enter them in 1 by 1 as I couldnt get it to work.

Check the NI one when you get it that works out a little odd too :)

BTW to give an example of this in action

3 items in the cart (using Norther Ireland (NI) as the postal setting.

Weight exactly 31 kilos

so equates to

1st 15 kg = 26.95
+
16 kg at 1.15 per kilo = 18.40

Total = 45.35

Ecart = 39.35

I must admit Im lost on that.

where you are charging 1.15 for each additional kg over 15, the amount =that needs to be subtracted from the Northern Ireland Over 15kg 20Supplement rule is:

1.15 * 15 = 17.25

the rule should be created as:
Subtotal of column 'TotalWeight' 'times' '1.15' 'minus' '17.25'


to be sure what the total weight in the cart is, add the following code to your page:
<?php echo WA_eCart_DisplayWeight($eCart1, $eCart1->TotalColumn("TotalWeight")); ?>

Thank you so much Jason your an absolute star. I completely missed the point until now. :)

Mike

no worries.
