Check if cart = 0 / coupon used

Check if cart = 0 / coupon used

Hello!

I would like to check if the customer cart value = 0 at the checkout (because of using a coupon).

If he uses it, I want to set the payment-method select area to display: none; because then it is useless.

With which function or query can I check whether the customer entered a coupon code or the total order amount is 0?

if ($order_total == 0) doesn't work..

Thank you!

Hi and thanks for the answer.

But the customer should have a product in cart and then I want to check if he uses a coupon, that makes the total value 0. Because then I want to hide the payment settings.

See controller / checkout.php

$cart->getSum();

Aw: Check if cart = 0 / coupon used

How can I include this in the payment.php?

I also tried with

<?php print formatprice($this->summ_payment);?><?php print $this->_tmp_ext_payment?>

but this always shows 0..

If I want to execute the function getSum(); the page is displayed incorrect..

Try
Change
Controller / checkout

function step2save(){

after
$cart->setShippingId(0);
$cart->setShippingPrId(0);
$cart->setShippingPrice(0);
$cart->setPaymentId(0);
$cart->setPaymentParams("");
$cart->setPaymentPrice(0);

Add

if ($cart->getSum(0, 1, 0)==0){
$jshopConfig->without_payment = 1;
}

Perfect!

Thank you very much.

It now redirects directly to step5 but this is no problem.
