Based on a custom field set a value in the cart...

-- HikaShop version -- : 2.3.2
-- Joomla version -- : 3.3.3

Hi,

I want to have a drop down list in the checkout process that has two values Yes and No. That is easy enough, however I want to add/remove a line item in the cart based on what is selected. So if YES is selected add a line to cart of:

Cooler Box 1.00

if NO then I want

Cooler Box 0.00

Naturally as those changes are made I need the total of the cart updated as part of the checkout process.

Hi,

You can create this custom field thanks to our custom fields system.
Create a custom field with the type "order" via the menu Display > Custom fields, and set it as a dropdown with the desired values.

Then you will have to create your own plugin to edit the cart based on the value of this custom field.
So it require good PHP knwoledges, here is documentation for the plugins:

Hi,

OK, I can do the PHP side of things. My questions Hikashop are

1) What trigger do I hook off the custom field so that I know when the select box changes?
2) In that trigger how do I get hold of the cart global object so I can add/remove an item?
3) Will doing 2) change the total for the cart or will I have to perform a postback of some form?
