We need to use 2 different hooks:
- The first one just as yours without trying to change the price in it.
- The second one where you will change your cart item price.
The code:
<?php
add_filter( 'woocommerce_add_cart_item', 'add_custom_cart_item_data', 10, 2 );
function add_custom_cart_item_data( $cart_item_data, $cart_item_key ) {
if( isset( $_POST['new-width'] ) )
$cart_item_data['new-width'] = $_POST['new-width'];
if(isset( $_POST['new-height'] ) )
$cart_item_data['new-height'] = $_POST['new-height'];
return $cart_item_data;
}
add_action( 'woocommerce_before_calculate_totals', 'set_custom_cart_item_price', 20, 1 );
function set_custom_cart_item_price( $cart ) {
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;
if ( did_action( 'woocommerce_before_calculate_totals' ) >= 2 )
return;
// First loop to check if product 11 is in cart
foreach ( $cart->get_cart() as $cart_item ){
if( isset($cart_item['new-width']) && isset($cart_item['new-height'])
&& ! empty($cart_item['new-width']) && ! empty($cart_item['new-height']) )
$cart_item['data']->set_price( '30' );
}
}
?>Code goes in function.php file of your active child theme (or theme) or also in any plugin file.
