I need a solution to re-calculate the total tax amount.
Is there an easy solution to just overwrite it?
This was my approach:
add_action( 'woocommerce_calculate_totals', 'calc_total_tax', 10, 1 );
function calc_total_tax( $cart_object ) {
if ( ! WC()->cart->is_empty() ) {
// actual taxes which are calculated in another method
$tax = floatval(123);
$cart_object->set_total_tax( $tax );
}
}
My debugger is showing the right value for $cart_object->totals['total_tax'] but the output is still the old value.
What am I missing here?
add_action( 'woocommerce_calculate_totals', 'calc_total_tax', 10, 1 );
function calc_total_tax( $cart_object ) {
if ( ! WC()->cart->is_empty() ) {
// actual taxes which are calculated in another method
$tax = floatval(123);
$cart_object->set_cart_contents_taxes( [1 => $tax] );
}
}

I previously had this code to add custom field values to the Order and Order emails. This worked and still works but I'm getting errors in the error log due to the code being depreciated:
add_action ('woocommerce_add_order_item_meta', 'add_item_meta', 10, 2);
function add_item_meta( $item_id, $values ) {
if ( empty( $values['_goodlen'] ) ) {
return;
}
woocommerce_add_order_item_meta( $item_id, 'Flavours', $values['_goodlen'] );
}
I've replaced it with:
add_action ('woocommerce_checkout_create_order_line_item', 'add_item_meta', 10, 2);
function add_item_meta( $item_id, $values ) {
if ( empty( $values['_goodlen'] ) ) {
return;
}
woocommerce_checkout_create_order_line_item( $item_id, 'Flavours', $values['_goodlen'] );
}
But that no longer adds the content to the email and orders.
Any ideas or help would be much appreciated.
Ah, I think I may have answered my question. Been looking around for ages and found this code:
add_action( 'woocommerce_checkout_create_order_line_item', 'custom_checkout_create_order_line_item', 20, 4 );
function custom_checkout_create_order_line_item( $item, $cart_item_key, $values, $order ) {
// Get a product custom field value
$custom_field_value = get_post_meta( $item->get_product_id(), '_goodlen', true );
// Update order item meta
if( isset( $values['_goodlen'] ) ) {
$item->update_meta_data( 'Flavours', $values['_goodlen'] );
}
}
Seems to work and display in both order and order email and doesn't throw up any errors in the log.
In Woocommerce, I used jQuery to calculate a custom price on a single product pages, and now need to pass this value to the cart.
The desired behavior is to pass the new price retrieved from the hidden field to the cart item price.
Here is my actual code:
// Hidden input field in single product page
add_action( 'woocommerce_before_add_to_cart_button', 'custom_hidden_product_field', 11, 0 );
function custom_hidden_product_field() {
echo '<input type="hidden" id="hidden_field" name="custom_price" class="custom_price" value="">';
}
// The code to pass this data to the cart:
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 ) {
if( ! empty( $_REQUEST['custom_price'] ) ) {
// Set the custom data in the cart item
$cart_item_data['custom_data']['custom_price'] = $_REQUEST['custom_price'];
$data = array( 'custom_price' => $_REQUEST['custom_price'] );
// 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;
}
And check both $data and $cart_item_data to see that they both return the custom_price data that is calculated on the page.
However, I go to view cart, and the value of the line item is still 0.
I set a var equal to the WC()->session->set( 'custom_data', $data ); and then var_dump to check it, but this returns NULL which might just be what it returns, I'm not entirely sure because I've never used it.
I should also add that I have the regular_price in the product backend set to 0. When I erase this (and leave it blank) I get back the error:
Warning: A non-numeric value encountered in
C:\xampp\htdocs\my-transfer-source\wp-content\plugins\woocommerce\includes\class-wc-discounts.php on line 85
I'm wondering if I've missed something here, and if someone could lend some light onto this? Thanks
Update 2021 - Handling custom price item in mini cart
First for testing purpose we add a price in the hidden input field as you don't give the code that calculate the price:
// Add a hidden input field (With a value of 20 for testing purpose)
add_action( 'woocommerce_before_add_to_cart_button', 'custom_hidden_product_field', 11 );
function custom_hidden_product_field() {
echo '<input type="hidden" id="hidden_field" name="custom_price" class="custom_price" value="20">'; // Price is 20 for testing
}
Then you will use the following to change the cart item price (WC_Session is not needed):
// Save custom calculated price as custom cart item data
add_filter( '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 ) {
if( isset( $_POST['custom_price'] ) && ! empty( $_POST['custom_price'] ) ) {
// Set the custom data in the cart item
$cart_item_data['custom_price'] = (float) sanitize_text_field( $_POST['custom_price'] );
// Make each item as a unique separated cart item
$cart_item_data['unique_key'] = md5( microtime().rand() );
}
return $cart_item_data;
}
// For mini cart
add_action( 'woocommerce_cart_item_price', 'filter_cart_item_price', 10, 2 );
function filter_cart_item_price( $price, $cart_item ) {
if ( isset($cart_item['custom_price']) ) {
$args = array( 'price' => floatval( $cart_item['custom_price'] ) );
if ( WC()->cart->display_prices_including_tax() ) {
$product_price = wc_get_price_including_tax( $cart_item['data'], $args );
} else {
$product_price = wc_get_price_excluding_tax( $cart_item['data'], $args );
}
return wc_price( $product_price );
}
return $price;
}
// Updating cart item price
add_action( 'woocommerce_before_calculate_totals', 'change_cart_item_price', 30, 1 );
function change_cart_item_price( $cart ) {
if ( ( is_admin() && ! defined( 'DOING_AJAX' ) ) )
return;
if ( did_action( 'woocommerce_before_calculate_totals' ) >= 2 )
return;
// Loop through cart items
foreach ( $cart->get_cart() as $cart_item ) {
// Set the new price
if( isset($cart_item['custom_price']) ){
$cart_item['data']->set_price($cart_item['custom_price']);
}
}
}
Code goes in functions.php file of your active child theme (or active theme). Tested and works.
We have a booking system which should allow only one product in the cart (when customers adds next product, previous one should be deleted from the cart).
Until today we have been using following code:
add_filter( 'woocommerce_add_to_cart_validation', 'b_only_one_in_cart', 99, 2 );
function b_only_one_in_cart( $passed, $added_product_id ) {
wc_empty_cart();
return $passed;
}
But it ceased to work (and I can't find why). Has something changed in the recent version of WooCommerce? How can I get it to work again?
You could use WC()->cart->empty_cart(); instead
function filter_woocommerce_add_to_cart_validation( $passed, $product_id, $quantity, $variation_id = null, $variations = null ) {
// When NOT empty
if ( ! WC()->cart->is_empty() ) {
// Empties the cart and optionally the persistent cart too.
WC()->cart->empty_cart();
}
return $passed;
}
add_filter( 'woocommerce_add_to_cart_validation', 'filter_woocommerce_add_to_cart_validation', 10, 5 );
If the above does not work for some reason, you can also apply it in the following way: (Solution for PHP 7.3 and up)
// Used to calculate totals
function action_woocommerce_before_calculate_totals( $cart ) {
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;
if ( did_action( 'woocommerce_before_calculate_totals' ) >= 2 )
return;
// Get cart
$get_cart = $cart->get_cart();
// Solution for PHP 7.3 and up
foreach ( $get_cart as $cart_item_key => $cart_item ) {
// NOT last element
if ( $cart_item_key !== array_key_last( $get_cart ) ) {
// Remove a cart item
$cart->remove_cart_item( $cart_item_key );
}
}
}
add_action( 'woocommerce_before_calculate_totals', 'action_woocommerce_before_calculate_totals', 10, 1 );
I'm working on woocommerce API plugin development and trying to pass custom cart item data using the below code in add to cart API endpoint.
$cart_item_key = WC()->cart->add_to_cart( $product_id, $quantity, $variation_id, $variations, array('margin' => 200));
and want to use that custom cart item data on woocommerce_before_calculate_totals hook (see code below) but can't getting custom cart item data ($cart_item['margin']) there.
add_action( 'woocommerce_before_calculate_totals', 'custom_cart_item_price', 30, 1 );
function custom_cart_item_price( $cart ) {
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;
foreach ( $cart->get_cart() as $cart_item ) {
if( isset($cart_item['margin']) ){
$final_price = ($cart_item['data']->get_price() + $cart_item['margin']);
$cart_item['data']->set_price($final_price);
}
}
}
I have installed Woocommerece 4.9 version, please help me to solve this issue.
Thanks in advance.
I had kind of the same problem, the issue was there was another plugin that might have a higher priority on the filter. It was a Role based pricing plugin, after deactivating it, everything worked. So just check if there is no other thing overwriting the function.
To do a test I used the woocommerce_add_to_cart_validation hook and I added a product to cart with add_to_cart() method of the WC_Cart class.
add_action( 'woocommerce_add_to_cart_validation', 'add_product_to_cart_programmatically', 10, 3 );
function add_product_to_cart_programmatically( $passed, $product_id, $quantity) {
$product_id = 166; // product id to add
$quantity = 10; // quantity product to add
WC()->cart->add_to_cart( $product_id, $quantity, 0, array(), array( 'margin' => 200 ) );
return $passed;
}
Once the product has been added to the cart, I can apply a custom price based on the custom cart item data:
add_action( 'woocommerce_before_calculate_totals', 'custom_cart_item_price', 30, 1 );
function custom_cart_item_price( $cart ) {
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;
foreach ( $cart->get_cart() as $cart_item ) {
if ( isset( $cart_item['margin'] ) && ! empty( $cart_item['margin'] ) ) {
$final_price = $cart_item['data']->get_price() + $cart_item['margin'];
$cart_item['data']->set_price( $final_price );
}
}
}
As recommended by #danielsalare you can try to increase the priority of the action, as in my example above.
I had a similar problem and found this solution: First, we add the custom products to Woocommerce. Second, we generate an identifier (ID), and later we add it.
for example, obtain product-id trow a with $_POST
$myProduct = $_POST['myProduct'];
$myProduct_id = WC()->cart->generate_cart_id($myProduct);
if (!WC()->cart->find_product_in_cart($myProduct_id )) {
WC()->cart->add_to_cart($myProduct);
}
I have an ACF field "DeliverySpeed" attached to Products with the values 'Fast' and 'Slow'
I would like to update this field to change to value 'Slow' every time the product stock is zero or less (product on backorder)
I am still learning PHP so far this is what I got to but I am sure different things are missing, I just don't know in which direction to go:
based on acf update field documentation
function automatically_change_delivery( ) {
global $product;
$fieldkey = "DeliverySpeed";
$valueslow = "Slow";
if($product->get_stock_quantity()<0) { update_field( $field_key, $valueslow, $post_id );
} }
Thank you in advance for the attention and advice.
The following code will update automatically your product custom field once order has reduced product stock levels. So when product has stock the custom field value will be 'Fast' otherwise 'Slow'.
The code:
add_action( 'woocommerce_payment_complete', 'update_product_custom_field_after_reduced_stock_levels', 20, 2 );
add_action( 'woocommerce_order_status_completed', 'update_product_custom_field_after_reduced_stock_levels', 20, 2 );
add_action( 'woocommerce_order_status_processing', 'update_product_custom_field_after_reduced_stock_levels', 20, 2 );
add_action( 'woocommerce_order_status_on-hold', 'update_product_custom_field_after_reduced_stock_levels', 20, 2 );
function update_product_custom_field_( $order_id, $order = '' ) {
// Continue only when order has reduced product stock levels
if ( wc_string_to_bool( get_post_meta( $order_id, '_order_stock_reduced', true ) ) )
return $order_id; // Exit
if( ! $order || ! is_a( $order, 'WC_Order') ) {
$order = wc_get_order( $order_id ); // Get the WC_Order object if it's empty
}
$field_key = 'DeliverySpeed';
// Loop through order items
foreach ( $order->get_items() as $item ) {
$product = $cart_item['data'];
$product_id = $product->get_id();
$stock_qty = $product->get_stock_quantity();
$field_value = get_field( $field_key, $product_id ); // Get ACF field value
if ( $stock_qty <= 0 && $field_value === 'Fast' ) {
update_field( $field_key, 'Slow', $product_id );
}
elseif ( $stock_qty > 0 && $field_value === 'Slow' ) {
update_field( $field_key, 'Fast', $product_id );
}
}
}
Code goes in functions.php file of the active child theme (or active theme). It should works.
