Determine whether on shop page in woocommerce - php

Question

My client wants the checkout to be "streamlined" to skip the cart page and go straight to checkout one product at a time. I got that covered but I also need to automatically empty the cart if the customer decides not to confirm checkout.
For this I wanted to check whether or not I'm on any other page than cart or checkout and do it there but all the commands I tried (is_shop(), is_front_page(), is_page('Shop'), is_product(), is_home()) always return false so I'm not sure what to do about it. This is how I'm trying to do it (in my themses functions.php):
function reset_cart_front() {
global $woocommerce;
echo "Attempting to empty<br>";
if (is_shop()) {
echo "is right page<br>";
$woocommerce->cart->empty_cart();
} else {
echo "is not right<br>";
}
}
add_action( 'init', 'reset_cart_front' );
what gives?

Answer 1

Nevermind, I figure it out!
function reset_cart_shop_loop() {
global $woocommerce;
$woocommerce->cart->empty_cart();
}
add_action( 'woocommerce_before_shop_loop', 'reset_cart_shop_loop' );

Correct me if I'm wrong...but I think you should check if the current page is_checkout(), and empty the cart if it's not:
function reset_cart_front() {
global $woocommerce;
if ( !is_checkout() ) {
$woocommerce->cart->empty_cart();
}
}
add_action( 'template_redirect', 'reset_cart_front' );
I also think 'init' is too early to hook (and would recommend trying 'template_redirect').
