I've got a matrix for my price modifiers. I don't map the base price field because I want to use the modifiers price as the full price.

So when I use my {price} variable I get the price without tax. I've tried {price:plus_tax}, but that doesn't seem to work. Everything is ok when I view my cart, but I really want the option to show the price with or without the tax in the step before.


The price:plus_tax tag won't work with a text field. It needs to be one of the various CartThrob Price Fieldtypes to use that tag.

If you use the {exp:cartthrob:item_options} tag to display your matrix modifiers, you'll be able to use :plus_tax.

  • That does work indeed! But I did a little custom coding for my purpose and did it this way. ` {if member_group != "7"} {exp:cartthrob:arithmetic prefix="" expression="({price} * {cart_tax_rate}) + {price}"} {/if}
