I have some meal packages to sell. For example.
Chicken meal has variations: 10 pack, 14 pack, 18 pack.
I want to disable flat_rate:3 when people order 10 pack. But I don’t know how to get the variation.
My code is below:
function hide_one_delivery( $rates, $item_id ) {
global $woocommerce, $product;
$10_pack = 0;
foreach ( $woocommerce->cart->cart_contents as $product ) {
$variation_data = $product->get_variation_attributes();
$variation_detail = woocommerce_get_formatted_variation( $variation_data, true );
if( $variation_detail == "10 pack" ){
$10_pack += 1;
}
}
if ($10_pack > 0){
unset( $rates['flat_rate:3'] );
}
return $rates;
}
add_filter( 'woocommerce_package_rates', 'hide_one_delivery', 100 );
It's not working. Can anyopne please help?
Just look into the product array, and you can get the variation data from the product array.
function hide_one_delivery( $rates, $item_id ) {
global $woocommerce;
foreach ( $woocommerce->cart->cart_contents as $product ) {
//$product is a array, and 10-pack is the slug of the attribute name
if ( $product['variation_id'] && in_array('10-pack', $product['variation']) ) {
unset( $rates['flat_rate:3'] );
break;
}
}
return $rates;
}
add_filter( 'woocommerce_package_rates', 'hide_one_delivery', 100, 2 );
This code will allow you to add the variation to your cart.php page. My example has a name because I name my Variation "PkgDesc" when I added it to the Cart Session. This is code that you need to add to the Cart.php page.
Add the line of code after the foreach() line (around line 48):
$pkgDesc= apply_filters( 'woocommerce_cart_item_product_id', $cart_item['variation'], $cart_item, $cart_item_key );
Now add the code below after your product title (// Meta data) (around line 85)
echo ": ";
echo $pkgDesc['PkgDesc'];
Your Cart line item will now look like this:
Chicken meal: 10 pack

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 );
Trying to add the order subtotal in woocommerce my-account/orders table but I can't seem to get it to display. Currently it adds the column and the label but its not displaying the orders sub total. I am currently using the code below :
add_filter( 'woocommerce_account_orders_columns',
'add_account_orders_column', 10, 1 );
function add_account_orders_column( $columns ){
$columns['item_subtotal_tax_excl'] = __( 'Sub-total', 'woocommerce' );
return $columns;
}
add_action( 'woocommerce_my_account_my_orders_column_custom-column',
'add_account_orders_column_rows' );
function add_account_orders_column_rows( $order ) {
// Example with a custom field
if ( $value = $order->get_meta( 'item_subtotal_tax_excl' ) ) {
echo esc_html( $value );
}
}
Subtotal like in cart doesn't exist in WooCommerce Orders meta data, so you need to get it and calculate it from order items:
add_filter( 'woocommerce_account_orders_columns', 'add_account_orders_column', 10, 1 );
function add_account_orders_column( $columns ){
$columns['item_subtotal_tax_excl'] = __( 'Sub-total', 'woocommerce' );
return $columns;
}
add_action( 'woocommerce_my_account_my_orders_column_custom-column', 'display_account_orders_column_rows_value' );
function display_account_orders_column_rows_value( $order ) {
$subtotal = 0; // Initializing
// Loop through order items (line items)
foreach ( $order->get_items() as $item ) {
// Sum item subtotal excluding taxes and not discounted
$subtotal += $item->get_subtotal();
}
echo $subtotal;
}
Code goes in functions.php file of your active child theme (or active theme). Tested and works.

return $columns;
}
add_action(
'woocommerce_my_account_my_orders_column_item_subtotal_tax_excl',
'add_account_orders_column_rows' );
function add_account_orders_column_rows( $order ) {
// Example with a custom field
if ( $value = $order->get_subtotal() ) {
echo esc_html( $value );
}
}
I wrote a very small function to disable installation as a method (from table rate shipping plugin) if a product is not in the cart or if the quantity of that product in the cart is less than 6.
This works, but only when I click on "update cart" button and not, for example, when I click on cart.
here's the function, directly from my function.php file in my custom theme:
function disable_installation_for_less_than( $rates ) {
global $woocommerce;
$items = $woocommerce->cart->get_cart();
$installation = $rates['table_rate_shipping_installation'];
foreach ( $items as $item => $values ) {
$productID = $values['product_id'];
$productQuantity = $values['quantity'];
unset( $rates['table_rate_shipping_installation'] );
if ( $productID == 2412 ) {
if ( $productQuantity < 6 ) {
unset( $rates['table_rate_shipping_installation'] );
} else {
array_push($rates, $installation);
}
}
}
return $rates;
}
add_filter( 'woocommerce_package_rates', 'disable_installation_for_less_than', 10, 3 );
Any idea why? am I using the wrong hook?
Thanks for any help
Also, rather then un-setting the installation and re-set it only when needed, is there a better way to say "if this product is NOT in the cart" then remove this?
thanks
Ok, I managed to solve it this way:
function disable_installation_for_less_than( $rates ) {
global $woocommerce;
$items = $woocommerce->cart->get_cart();
$showInstallation= false;
foreach ( $items as $item => $values ) {
$productID = $values['product_id'];
$productQuantity = $values['quantity'];
if ( $productID == 2412 ) {
$showInstallation= true;
if ( $productQuantity < 6 ) {
unset( $rates['table_rate_shipping_installation'] );
}
}
}
if ($showInstallation== false){
unset( $rates['table_rate_shipping_installation'] );
}
return $rates;
}
add_filter( 'woocommerce_package_rates', 'disable_installation_for_less_than', 10, 2 );
It's working now.
I think this code should work but not exactly sure where to place it. Everywhere I have tried has failed so far...
add_action('init', 'woocommerce_clear_cart');
function woocommerce_clear_cart() {
global $woocommerce, $post, $wpdb;
$url = explode('/', 'http://'.$_SERVER["HTTP_HOST"] . $_SERVER["REQUEST_URI"]);
$slug=$url[4];
$postid = $wpdb->get_var("SELECT ID FROM $wpdb->posts WHERE post_status='publish' AND post_name = '$slug'");
if ($postid){
if ($postid == PRODUCTID1 || $postid == PRODUCTID2){
$woocommerce->cart->empty_cart();
}
}
}
Unfortunately there is no 'action' hook before WooCommerce adds an item to the cart. But they have a 'filter' hook before adding to cart.
That is how I use it:
add_filter( 'woocommerce_add_cart_item_data', 'woo_custom_add_to_cart' );
function woo_custom_add_to_cart( $cart_item_data ) {
global $woocommerce;
$woocommerce->cart->empty_cart();
// Do nothing with the data and return
return $cart_item_data;
}
Based on the accepted answer and the latest Woo version 2.5.1 I updated the function to be slightly cleaner using the code woo uses in class-wc-checkout.php to clear the cart
add_filter( 'woocommerce_add_cart_item_data', '_empty_cart' );
function _empty_cart( $cart_item_data ) {
WC()->cart->empty_cart();
return $cart_item_data;
}
There is a filter/hook that runs before an item is added to the cart as each product goes through validation before it is added.
So when validating a product, we can check if the item if there are already items in the cart and clears those (if the current item is able to be added) and adds an error message.
/**
* When an item is added to the cart, remove other products
*/
function so_27030769_maybe_empty_cart( $valid, $product_id, $quantity ) {
if( ! empty ( WC()->cart->get_cart() ) && $valid ){
WC()->cart->empty_cart();
wc_add_notice( 'Whoa hold up. You can only have 1 item in your cart', 'error' );
}
return $valid;
}
add_filter( 'woocommerce_add_to_cart_validation', 'so_27030769_maybe_empty_cart', 10, 3 );
This worked like a charm for me, removes the previous product and adds the new one with the new product configuration. Cheers
Update: For WooCommerce 3.0.X
function check_if_cart_has_product( $valid, $product_id, $quantity ) {
if(!empty(WC()->cart->get_cart()) && $valid){
foreach (WC()->cart->get_cart() as $cart_item_key => $values) {
$_product = $values['data'];
if( $product_id == $_product->get_id() ) {
unset(WC()->cart->cart_contents[$cart_item_key]);
}
}
}
return $valid;
}
add_filter( 'woocommerce_add_to_cart_validation', 'check_if_cart_has_product', 10, 3 );
For WooCommerce version less than 3.0.X
function check_if_cart_has_product( $valid, $product_id, $quantity ) {
if(!empty(WC()->cart->get_cart()) && $valid){
foreach (WC()->cart->get_cart() as $cart_item_key => $values) {
$_product = $values['data'];
if( $product_id == $_product->id ) {
unset(WC()->cart->cart_contents[$cart_item_key]);
}
}
}
return $valid;
}
add_filter( 'woocommerce_add_to_cart_validation', 'check_if_cart_has_product', 10, 3 );
You have two options:
WooCommerce Min/Max Quantities extension
The following code added to your functions.php theme file
add_filter ( 'woocommerce_before_cart' , 'allow_single_quantity_in_cart' );
function allow_single_quantity_in_cart() {
global $woocommerce;
$cart_contents = $woocommerce->cart->get_cart();
$keys = array_keys ( $cart_contents );
foreach ( $keys as $key ) {
$woocommerce->cart->set_quantity ( $key, 1, true );
}
}
Don't add functions directly to your commerce files...you'll lose all your code when you update.
User functions should always be hooked through the functions.php of your theme.
Add this to your child-themes functions.php (tested in 2022, requires PHP 7 or higher):
add_filter('woocommerce_add_cart_item_data', function($cart_data) {
wc_empty_cart();
return $cart_data;
}, 99);
The "woocommerce_add_cart_item_data" filter fires every time a new item is added to the cart. We use this chance to call "wc_empty_cart" which empties the cart and optionally the persistent cart too. The new items is therefore alone in the cart.
Try this,
For removing the all products from the cart and adding the last added one,
//For removing all the items from the cart
global $woocommerce;
$woocommerce->cart->empty_cart();
$woocommerce->cart->add_to_cart($product_id,$qty);
class file is wp-content/plugins/woocommerce/classes/class-wc-cart.php.
You can add the above code on the add to cart function in functions.php.
Hope its works..
Eu coloco na function.php do tema, o que faço ou no woocomerce
function check_if_cart_has_product( $valid, $product_id, $quantity ) {
if(!empty(WC()->cart->get_cart()) && $valid){
foreach (WC()->cart->get_cart() as $cart_item_key => $values) {
$_product = $values['data'];
if( $product_id == $_product->id ) {
wc_add_notice( 'The product is already in cart', 'error' );
return false;
}
}
}
return $valid;
}
add_filter( 'woocommerce_add_to_cart_validation', 'check_if_cart_has_product', 10, 3 );
On WordPress 5.6.1. no need to add a custom filter or write code there is an option to limit one product add to the cart.
