WooCommerce Overpricing Not Working
I created a hidden input element using woocommerce_before_add_to_cart_button
hook
function add_gift_wrap_field() {
?>`<input type="hidden" id="price_val" name="added_price" value="100.34">`<?php
}
add_action( 'woocommerce_before_add_to_cart_button', 'add_gift_wrap_field' );
Saving fields for a product:
function save_gift_wrap_fee( $cart_item_data, $product_id ) {
if( isset( $_POST['added_price'] ) ) {
$cart_item_data = array();
$cart_item_data[ "gift_wrap_fee" ] = "YES";
$cart_item_data[ "gift_wrap_price" ] = 100;
}
return $cart_item_data;
}
add_filter( 'woocommerce_add_cart_item_data', 'save_gift_wrap_fee', 99, 2 );
Now I can highlight $_POST['added_price']
inside this tag woocommerce_before_calculate_totals
.
The code I wrote is shown below:
function calculate_gift_wrap_fee( $cart_object ) {
if( !WC()->session->__isset( "reload_checkout" )) {
/* Gift wrap price */
$additionalPrice = number_format($_POST['added_price'], 2);
$additionalPrice = floatval($additionalPrice);
//echo $additionalPrice; exit(); shows the value
foreach ( $cart_object->cart_contents as $key => $value ) {
if( isset( $value["gift_wrap_fee"] ) ) {
/* Woocommerce 3.0 + */
$orgPrice = floatval( $value['data']->get_price() );
$value['data']->set_price( $orgPrice + $additionalPrice ); //not adding the $additionalPrice here.
}
}
}
}
add_action( 'woocommerce_before_calculate_totals', 'calculate_gift_wrap_fee', 99 );
What am I doing wrong here?

Here is a complete clean, tested and working solution based on your code.
Here I added your custom field key
/ value
to the cart object for the associated cart item instead of getting the Post value in your function . calculate_gift_wrap_fee()
This way, the value of the custom field cannot be lost and the new pricing is reliable.
I commented 'gift_wrap_fee'
and 'gift_wrap_price'
as they are not needed right now (but you can uncomment them if you like).
Here's the code:
// The hidden product custom field
add_action( 'woocommerce_before_add_to_cart_button', 'add_gift_wrap_field' );
function add_gift_wrap_field() {
?>
<input type="hidden" id="price_val" name="added_price" value="100.34">
<?php
}
// Adding the custom field to as custom data for this cart item in the cart object
add_action( 'woocommerce_add_cart_item_data', 'save_custom_fields_data_to_cart', 10, 2 );
function save_custom_fields_data_to_cart( $cart_item_data, $product_id ) {
$bool = false;
$data = array();
if( ! empty( $_REQUEST['added_price'] ) ) {
$cart_item_data['custom_data']['added_price'] = $_REQUEST['added_price'];
// Below this 2 values are not really needed (I think)
// (You can uncomment them if needed)
## $cart_item_data['custom_data']['gift_wrap_fee'] = 'YES';
## $cart_item_data['custom_data']['gift_wrap_price'] = 100;
// below statement make sure every add to cart action as unique line item
$cart_item_data['custom_data']['unique_key'] = md5( microtime().rand() );
WC()->session->set( 'custom_data', $data );
}
return $cart_item_data;
}
// Changing the cart item price based on custom field calculation
add_action( 'woocommerce_before_calculate_totals', 'calculate_gift_wrap_fee', 10, 1 );
function calculate_gift_wrap_fee( $cart_object ) {
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;
// Iterating though cart items
foreach ( $cart_object->get_cart() as $cart_item ) {
// Continue if we get the custom data for the current cart item
if( ! empty( $cart_item['custom_data'] ) ){
// Get the custom field "added price" value
$added_price = number_format( $cart_item['custom_data']['added_price'], 2 );
// The WC_Product object
$wc_product = $cart_item['data'];
// Get the price (WooCommerce versions 2.5.x to 3+)
$product_price = method_exists( $wc_product, 'get_price' ) ? floatval($wc_product->get_price()) : floatval($wc_product->price);
// New price calculation
$new_price = $product_price + $added_price;
// Set the calculeted price (WooCommerce versions 2.5.x to 3+)
method_exists( $wc_product, 'set_price' ) ? $wc_product->set_price( $new_price ) : $wc_product->price = $new_price;
}
}
}
The code goes in the function.php file of your active child theme (or theme), as well as any plugin file.
This code has been tested and works with WooCommerce versions 2.5.x to 3+.
