How and Where are defined these variables?

[skyihoki]

 I have a question about the variable.

 

 When you click the item,you can see the amount of detail.

--------------------------------------------------------------------------------------------

There are --items in your cart,

 

Total product(tax incl.)    -----

 

Total shipping(tax incl.)   -----

 

Total (tax incl.)                -----

 

----------------------------------------------------------------------------------------------

 

How are　defined　these　variables(Total product(tax incl.),Total shipping(tax incl.)  ,Total (tax incl.) )?

 

And where PHP file are these?  

 

 

Thank you.

The shipping cost specifically is defined by your preferred shipping method in the backend - so the shipping method at position 0.

 

The values for the shopping cart are set in the files for the blockcart module so /modules/blockcart/blockcart.php . 

 

Maybe we could better help you if you tell us exactly what you are trying to do?

I want to customize carrier shipping cost .

 

I made EMS carrier in Carrier->Shipping, but this carrier doesn't correspond to the update.

 

I think of  getting EMS using the API , and handling with the carrier.

 

So, I wanted to know these variable to need displaying EMS API.

 

1->Sends the total amount and the country ID, and to get the shipping cost from the EMS API

 

2-> Substitute the obtained this shipping cost on these variable

 

3->Total shipping(tax incl.)←Display this shipping cost from API

 

4->To be displayed in the order screen

 

 

This is the ultimate goal!!

 

Please help me,Thank you.
