Which Hook is running after Woocommerce update cart button action - php

Question

i need to know which hook is running after clicking the update cart button in the cart page .
That is in cart page we have 4 button , update cart , continue shopping, proceed to checkout , apply coupon .
So i want to know which hook is run after update cart button is clicked . When customer click the update cart button after changing the quantity then i have to run a special function that can change total price in the cart , If some condition met , i will change the total price in the cart , and this total price need to pass to the checkout page also /
Please help .
For example
add_filter('after_update_cart_function_finished', 'special_function');
function special_function(){
$applied_coupons= WC()->cart->get_applied_coupons();
if(!empty($applied_coupons)){
$new_value=WC()->cart->get_cart_subtotal();
$discounted=WC()->cart->coupon_discount_totals;
$discounted_value=array_values($discounted)[0];
$new_value=$new_value-$discounted_value+100;
WC()->cart->set_total_price($new_value);
After this update all post_meta value that regarding to order total
}
}
Please see the following custom function that i write for to change value in cart
function action_woocommerce_cart_totals_after_order_total( ) {
$applied_coupons= WC()->cart->get_applied_coupons();
if(!empty($applied_coupons)){
$new_value=WC()->cart->get_cart_subtotal();
$discounted=WC()->cart->coupon_discount_totals;
$discounted_value=array_values($discounted)[0];
$new_value=$new_value-$discounted_value;
if($new_value<100){
$new_value=$new_value+5;
}
?>
<style>
.new-price-new{
color:black;
font-size: 17px;
}
</style>
<script>
jQuery(function($){
$(".order-total .woocommerce-Price-amount.amount").text("£<?php echo $new_value;?>");
$(".order-total .woocommerce-Price-amount.amount").hide();
$(".new-price").remove();
$('.order-total .woocommerce-Price-amount.amount').after('<div class="new-price-new">£<?php echo $new_value;?></div>');;
$(".new-price-new").show();
});
</script>
<?php
}
else{
?>
<script>
jQuery(function($){
$(".new-price-new").remove();
});
</script>
<?php }
};
add_action( 'woocommerce_cart_totals_after_order_total', 'action_woocommerce_cart_totals_after_order_total', 10, 0 );
And this function have many problems , i write this function because of some reason or some other function woocommerce is not calculating coupon price correctly , so i write this function for to manually update the product price in cart .Here if the cart value is more than 100 we provide free shipping other vise we will add 5 . Even this function is not working properly .

You should try woocommerce_update_cart_action_cart_updated action hook. I have revisited your code a bit. Try this:
add_action( 'woocommerce_update_cart_action_cart_updated', 'on_action_cart_updated', 20, 1 );
function on_action_cart_updated( $cart_updated ){
$applied_coupons = WC()->cart->get_applied_coupons();
if( count( $applied_coupons ) > 0 ){
$new_value = WC()->cart->get_cart_subtotal();
$discounted = WC()->cart->coupon_discount_totals;
$discounted_value = array_values($discounted)[0];
$new_value = $new_value-$discounted_value + 100;
WC()->cart->set_total( $new_value );
if ( $cart_updated ) {
// Recalc our totals
WC()->cart->calculate_totals();
}
}
}
Code goes in function.php file of your active child theme (or active theme). Untested. It could work.
Update: The WC_Cart set_total_price() method doesn't exist… I have replaced it by existing WC_Cart set_total()
