Line Total Not Showing Altered Price

Hello @douboy

HTML is always fetched via ajax, whether its on page load or on add to cart.
You need to update your prices using this hook
woocommerce_before_cart_contents

I did that and it works fine, until the page is refreshed. Then it reverts to the original prices, not the prices I calculate in the hook.

Only the line total.

This works fine for me.

add_action( 'woocommerce_before_cart_contents', 'custom_cart_total' );
function custom_cart_total() {

    WC()->cart->subtotal = 0;
    WC()->cart->total = 0;

}

Sorry, just noticed I was referencing the woocommerce_before_calculate_totals hook. I’ll try your recommendation. Thank you!

The woocommerce_before_cart_contents hook didn’t work at all. It used the no altered prices. Also, in your last post, I am not talking about the cart total, I’m talking about the line item total. The cart total is correct for me.

I only gave you an example to show how to update cart prices with this hook.
Does your code works with the normal cart & checkout pages?
Please share it so I can test. Give this code a try as well.

add_action( 'woocommerce_before_calculate_totals', 'custom_cart_total' );
function custom_cart_total() {

    foreach ( WC()->cart->get_cart() as $hash => $value ) {
    	$value['data']->set_price( 20 );
    }

}
add_action( 'woocommerce_before_cart_contents', function(){
	do_action( 'woocommerce_before_calculate_totals' );
}, 0 );

Here is my code:

add_filter( 'woocommerce_get_price_html', 'calculate_price_by_multiplier', 10, 2 );
add_filter( 'woocommerce_cart_item_price', 'custom_cart_price_display', 10, 3);
add_action( 'woocommerce_before_calculate_totals', 'custom_cart_price'); 

function calculate_price_by_multiplier($price, $product){
	
	if (is_null($product)) {
		return $price;
	}
	
	$multiplier = get_field('price_multiplier');
	$price = $product->get_price();
	
    if ($multiplier > 0){
        $price = $multiplier * $price;
    }
	
    return wc_price($price);
}

function custom_cart_price_display($price_text, $product_data, $cart_key) {
	
	if (is_null($product_data)){
    	return $price_text;
    }
	
	$product_id = (empty($product_data['variation_id'])) ? $product_data['product_id'] : $product_data['variation_id'];
	$product = wc_get_product($product_id);
	//$weight = floatval($product->get_weight());
	$price = $product->get_price();
	$multiplier = get_field('price_multiplier', $product_id);
	
	if ($multiplier > 0) {
		$price = $price * $multiplier;
	}
	
	return wc_price($price);

}

function custom_cart_price( $cart_object ) {
	
	$cart_items = $cart_object->cart_contents;

	if ( ! empty( $cart_items ) ) {
		
		foreach ( $cart_items as $key => $value ) {
			$product_id = $value['product_id'];
			$multiplier = get_field('price_multiplier', $product_id);
			$price = $value['data']->get_regular_price();
			
			if ($multiplier > 0){
				$value['data']->set_price( $price * $multiplier );
    		}
		}
	}
    
}

Ok, made some tests.
Your code is absolutely fine.
Now the extra snippet you have to add to make it work with side cart is

add_action( 'woocommerce_before_cart_contents', function(){
	WC()->cart->calculate_totals();
}, 0 );

Perfect..thank you very much! Great support. Will be buying the pro version today.
