I have used the hook woocommerce_before_calculate_totals but stuck in getting dynamic value in my function. Even i have used session but it didn't work on passing dynamic price.
The following snippet adds 100 to all the products in the cart, you can put your own conditions and pricing calculation there.
function calculate_product_price( $cart_object ) {
/* Gift wrap price */
$additionalPrice = 100;
foreach ( $cart_object->cart_contents as $key => $value ) {
//You can add your condition here
$quantity = floatval( $value['quantity'] );
$orgPrice = floatval( $value['data']->price );
$value['data']->price = ( ( $orgPrice + $additionalPrice ) * $quantity );
}
}
add_action( 'woocommerce_before_calculate_totals', 'calculate_product_price', 1, 1 );

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.
This code I wrote displays personalized information on the WooCommerce checkout page.
add_action( 'woocommerce_cart_totals_after_order_total', 'show_total_discount_cart_checkout', 9999 );
add_action( 'woocommerce_review_order_after_order_total', 'show_total_discount_cart_checkout', 9999 );
function show_total_discount_cart_checkout() {
$discount_total = 0;
foreach ( WC()->cart->get_cart() as $cart_item_key => $cart_item ) {
$product = $cart_item['data'];
$subtotal = WC()->cart->get_product_subtotal( $product, $cart_item['quantity'] );
$total = WC()->cart->total;
$pctm = 90.00;
$valor_descontado = $total - ($total / 100 * $pctm);
$sale_price = '10%';
$discount = ( WC()->cart->total - $valor_descontado );
$discount_total = $discount;
}
if ( $discount_total > 0 ) {
echo '<tr><th>VOCÊ RECEBERÁ DE CASHBACK:</th><td data-title="You">' . wc_price( $discount_total + WC()->cart->get_discount_total() ) .'</td></tr>';
}
}
The result:
I need this information to also be displayed in WooCommerce orders and emails. I believe I can come up with a solution myself to display this value on several other pages, but can someone first tell me how to save/store the value of this calculation?
First of all, I've rewritten your existing code for the following reasons:
Requesting subtotals and totals is best done outside the foreach loop, because otherwise these values will be overwritten every time
The result of $subtotal is not used anywhere in your code
Since the result of $subtotal is not used anyway, loop through the cart seems unnecessary
$sale_price is also not used anywhere in your code
Since $discount_total = $discount it is not necessary to use a new variable
A session variable is created/added
Your existing code, but optimized:
function action_woocommerce_after_order_total() {
// WC Cart NOT null
if ( ! is_null( WC()->cart ) ) {
// Get cart
$cart = WC()->cart;
// Getters
$cart_total = $cart->total;
$cart_discount_total = $cart->get_discount_total();
// Settings
$pctm = 90;
// Calculations
$discounted_value = $cart_total - ( $cart_total / 100 * $pctm );
$discount_total = $cart_total - $discounted_value;
// Greater than
if ( $discount_total > 0 ) {
// Result
$result = $discount_total + $cart_discount_total;
// The Output
echo '<tr class="my-class">
<th>' . __( 'VOCÊ RECEBERÁ DE CASHBACK', 'woocommerce' ) . '</th>
<td data-title="You">' . wc_price( $result ) . '</td>
</tr>';
// Set session
WC()->session->set( 'session_result', $result );
}
}
}
add_action( 'woocommerce_cart_totals_after_order_total', 'action_woocommerce_after_order_total', 10 );
add_action( 'woocommerce_review_order_after_order_total', 'action_woocommerce_after_order_total', 10 );
To answer your question:
Step 1) We get the result from the session variable and add it as order data, so that we can use/obtain this information everywhere via the $order object
// Add as custom order meta data and reset WC Session variable
function action_woocommerce_checkout_create_order( $order, $data ) {
// Isset
if ( WC()->session->__isset( 'session_result' ) ) {
// Get
$result = (float) WC()->session->get( 'session_result' );
// Add as meta data
$order->update_meta_data( 'result', $result );
// Unset
WC()->session->__unset( 'session_result' );
}
}
add_action( 'woocommerce_checkout_create_order', 'action_woocommerce_checkout_create_order', 10, 2 );
Step 2) Use the woocommerce_get_order_item_totals filter hook, which will allow you to add a new row to the existing tables with the $result.
The new row will be added in:
Email notifications
Order received (thank you page)
My account -> view order
function filter_woocommerce_get_order_item_totals( $total_rows, $order, $tax_display ) {
// Get meta
$result = $order->get_meta( 'result' );
// NOT empty
if ( ! empty ( $result ) ) {
// Add new row
$total_rows['total_result']['label'] = __( 'VOCÊ RECEBERÁ DE CASHBACK', 'woocommerce' );
$total_rows['total_result']['value'] = wc_price( $result );
}
return $total_rows;
}
add_filter( 'woocommerce_get_order_item_totals', 'filter_woocommerce_get_order_item_totals', 10, 3 );
In our woocommerce shop , customer can enter the custom width and height of the product and product price calculated based on this details .
For example if the initial price for a product is 50 . And customer add width =2, height=3 , then the price for this product is going to 50*2*3=300
for this we are using following code
// Save custom field value in cart item as custom data
add_filter( 'woocommerce_add_cart_item', 'calculate_custom_cart_item_prices', 30, 3 );
function calculate_custom_cart_item_prices( $cart_item_data, $product_id, $variation_id ) {
if ( isset($_POST['width']) && isset($_POST['height']) ) {
// Get the correct Id to be used (compatible with product variations)
$the_id = $variation_id > 0 ? $variation_id : $product_id;
$product = wc_get_product( $the_id ); // Get the WC_Product object
$product_price = (float) $product->get_price(); // Get the product price
// Get the posted data
$width = (float) sanitize_text_field( $_POST['width'] );
$height = (float) sanitize_text_field( $_POST['height'] );
$new_price = $width * $height * $product_price; // Calculated price
$cart_item_data['calculated-price'] = $new_price; // Save this price as custom data
}
return $cart_item_data;
}
// Set custom calculated price in cart item price
add_action( 'woocommerce_before_calculate_totals', 'set_calculated_cart_item_price', 20, 1 );
function set_calculated_cart_item_price( $cart ) {
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;
// Loop through cart items
foreach ( $cart->get_cart() as $cart_item ){
if( ! empty( $cart_item['calculated-price'] ) ){
// Set the calculated item price (if there is one)
$cart_item['data']->set_price( $cart_item['calculated-price'] );
}
}
And it is wormking , but the problem is:
when customer apply a 50% coupon code for this product then the
discount is coming as 25 , because it calculating based on 50*(50/100)=25;
But actually product new price is 300, so the discount should be
300*(50/100)=150;
Try updating your 'calculate_custom_cart_item_prices' function to something like this and see if that helps.
add_filter( 'woocommerce_add_cart_item', 'calculate_custom_cart_item_prices', 30, 2 );
function calculate_custom_cart_item_prices( $cart_item_data, $cart_item_key ) {
if ( isset($_POST['width']) && isset($_POST['height']) ) {
// Get the correct Id to be used (compatible with product variations)
$the_id = $cart_item_data['variation_id'] > 0 ? $cart_item_data['variation_id'] : $cart_item_data['product_id'];
$product = wc_get_product( $the_id ); // Get the WC_Product object
$product_price = (float) $product->get_price(); // Get the product price
// Get the posted data
$width = (float) sanitize_text_field( $_POST['width'] );
$height = (float) sanitize_text_field( $_POST['height'] );
$new_price = $width * $height * $product_price; // Calculated price
$cart_item_data['calculated-price'] = $new_price; // Save this price as custom data
}
return $cart_item_data;
}
My guess as to what is happening is a change in Woocommerce has changed the way the 'woocommerce_add_cart_item' filter works and so you need to update this function.
I am using woocommerce_before_calculate_totals for adding extra price in woocommerce. If you add a product in cart and selected the price, the total price is correct in the checkout, but if the customer create his account in same process and checkout then the price is added twice after proced payment. This is my code
function calculate_gift_wrap_fee( $cart_object ) {
$additionalPrice = 100;
foreach ( $cart_object->cart_contents as $key => $value ) {
if( isset( $value["gift_wrap_fee"] ) ) {
$orgPrice = floatval( $value['data']->price );
$value['data']->price = ( $orgPrice + $additionalPrice );
}
}
}
Please help
If customer choose Create Account option at the time checkout, woocommerce calls calculate_totals() second time ( after customer account registered and auto logged them ) in order to recalculate cart totals to reveal any role-based discounts that were unavailable before registering.
So what you can do is check for "reload_checkout" session which will be set before calling calculate_totals() second time.
So update your calculate_gift_wrap_fee like this
function calculate_gift_wrap_fee( $cart_object ) {
if( !WC()->session->__isset( "reload_checkout" )) {
/* Gift wrap price */
$additionalPrice = 100;
foreach ( $cart_object->cart_contents as $key => $value ) {
if( isset( $value["gift_wrap_fee"] ) ) {
$orgPrice = floatval( $value['data']->price );
$value['data']->price = ( $orgPrice + $additionalPrice );
}
}
}
}
add_action( 'woocommerce_before_calculate_totals', 'calculate_gift_wrap_fee', 99 );
Hi I need to add an extra price to product price while add to cart.
http://url/warenkorb/?add-to-cart=1539&added_price=5.00
I have used the code following code to achive this.
add_filter( 'woocommerce_add_cart_item', 'c_other_options_add_cart_item', 20, 1 );
function c_other_options_add_cart_item( $cart_item ) {
if (isset($cart_item['_other_options'])) :
if( isset($cart_item['_other_options']['product-price']) )
$extra_cost = floatval($cart_item['_other_options']['product-price']);
$cart_item['data']->adjust_price( $extra_cost );
// here the real adjustment is going on...
endif;
return $cart_item;
}
add_filter( 'woocommerce_add_cart_item_data', c_other_options_add_cart_item_data', 10, 2 );
function c_other_options_add_cart_item_data($cart_item_meta, $product_id){
global $woocommerce;
$product = new WC_Product( $product_id);
$price = $product->price;
if(empty($cart_item_meta['_other_options']))
$cart_item_meta['_other_options'] = array();
$cart_item_meta['_other_options']['product-price'] = esc_attr($_REQUEST['price']) - $price;
return $cart_item_meta;
}
It shows the modified price on add to cart page but not in the cart/checkout page. Please Help me to achieve this. Thanks in advance.
You have to use woocommerce_before_calculate_totals hook for this purpose,
like this
function calculate_extra_fee( $cart_object ) {
/* Extra fee */
$additionalPrice = 100;
foreach ( $cart_object->cart_contents as $key => $value ) {
/* if you want to add extra fee for particular product, otherwise remove the if condition */
if( $value['product_id'] == 100) {
$quantity = intval( $value['quantity'] );
$orgPrice = intval( $value['data']->price );
$value['data']->price = ( ( $orgPrice + $additionalPrice ) * $quantity );
}
}
}
add_action( 'woocommerce_before_calculate_totals', 'calculate_extra_fee', 1, 1 );
