I need to double the price for every product in Woocommerce frontend. For this I used the following code:
add_filter( 'woocommerce_product_get_price', 'double_price', 10, 2 );
function double_price( $price, $product ){
return $price*2;
}
But there is an error using this code. checkout page price is not correct.
for example the product orginal price is 10. We double the price by this code . so the product price is 20 now. When i added this product to the cart then cart and checkout page price is 40. That means this multiplication is take place in two times.
Please help to solve this.
Updated To double the price:
1) First you will restrict your code to single product and archives pages only:
add_filter( 'woocommerce_product_get_price', 'double_price', 10, 2 );
function double_price( $price, $product ){
if( is_shop() || is_product_category() || is_product_tag() || is_product() )
return $price*2;
return $price;
}
2) Then for cart and checkout pages, you will change the cart item price this way:
add_filter( 'woocommerce_add_cart_item', 'set_custom_cart_item_prices', 20, 2 );
function set_custom_cart_item_prices( $cart_data, $cart_item_key ) {
// Price calculation
$new_price = $cart_data['data']->get_price() * 2;
// Set and register the new calculated price
$cart_data['data']->set_price( $new_price );
$cart_data['new_price'] = $new_price;
return $cart_data;
}
add_filter( 'woocommerce_get_cart_item_from_session', 'set_custom_cart_item_prices_from_session', 20, 3 );
function set_custom_cart_item_prices_from_session( $session_data, $values, $key ) {
if ( ! isset( $session_data['new_price'] ) || empty ( $session_data['new_price'] ) )
return $session_data;
// Get the new calculated price and update cart session item price
$session_data['data']->set_price( $session_data['new_price'] );
return $session_data;
}
Code goes in function.php file of your active child theme (or theme) or also in any plugin file.
Tested and working. It will change all prices as you expect in cart, checkout and order pages…

I have a custom add to cart button in php for a single product:
Final total<br>
$<?php echo $row['purchase-price'] ?>.00<br><br>
<button onclick="window.location.href='https://yourdomain.com/checkout/?add-to-cart=362166';">Add to cart</button>
After clicking the button, it returned a "Sorry, this product cannot be purchased." error. I havent set the product price since the amount in <?php echo $row['purchase-price'] ?> is always changing. How to pass the amount set in php and pass it to product's final price?
First you will restrict your code to single product and archives pages only:
add_filter( 'woocommerce_product_get_price', 'double_price', 10, 2 );
function double_price( $price, $product ){
if( is_shop() || is_product_category() || is_product_tag() || is_product() ) {
global $wpdb;
//your query to get price from custom db
//FOR GET PRODUCT ID $product->get_id();
$price = $row['purchase-price'];
}
return $price;
}
Then for cart and checkout pages, you will change the cart item price this way:
add_filter( 'woocommerce_add_cart_item', 'set_custom_cart_item_prices', 20, 2 );
function set_custom_cart_item_prices( $cart_data, $cart_item_key ) {
global $wpdb;
//your query to get price from custom db
$new_price = $row['purchase-price'];
//FOR GET PRODUCT ID $cart_item['data']->get_id();
// Set and register the new calculated price
$cart_data['data']->set_price( $new_price );
$cart_data['new_price'] = $new_price;
return $cart_data;
}
add_filter( 'woocommerce_get_cart_item_from_session', 'set_custom_cart_item_prices_from_session', 20, 3 );
function set_custom_cart_item_prices_from_session( $session_data, $values, $key ) {
if ( ! isset( $session_data['new_price'] ) || empty ( $session_data['new_price'] ) )
return $session_data;
// Get the new calculated price and update cart session item price
$session_data['data']->set_price( $session_data['new_price'] );
return $session_data;
}
And in the last hit your custom url
<button onclick="window.location.href='https://yourdomain.com/?add-to-cart=362166&quantity=1';">Add to cart</button>
I am trying to set the functionality in Woocommerce on the Add to Cart button to only allow a particular product to be added once to the Cart.
Once a particular product has been added to cart the first time, the Add to Cart needs to be hidden.
In the cart I can have any number of products - just a max of quantity 1 for each product.
I was doing research and saw that I can use woocommerce_add_to_cart_validation hook. But have no idea how to start off.
How can I allow a particular product to be added once to the Cart?
Disable add to cart button if product is in cart using woocommerce_is_purchasable hook:
add_filter( 'woocommerce_is_purchasable', 'disable_add_to_cart_if_product_is_in_cart', 10, 2 );
function disable_add_to_cart_if_product_is_in_cart ( $is_purchasable, $product ){
// Loop through cart items checking if the product is already in cart
foreach ( WC()->cart->get_cart() as $cart_item ){
if( $cart_item['data']->get_id() == $product->get_id() ) {
return false;
}
}
return $is_purchasable;
}
Code goes in function.php file of your active child theme (or active theme). Tested and works (even for product variations in variable products).
Original answer:
Here is an example using woocommerce_add_to_cart_validation hook and that will do the trick (preventing add to cart action and displaying a custom notice when needed), and using a custom utility function that will remove quantity field for your specific defined product ID:
add_filter( 'woocommerce_add_to_cart_validation', 'limit_cart_items_from_category', 10, 3 );
function limit_cart_items_from_category ( $passed, $product_id, $quantity ){
// HERE define your product ID
$targeted_product_id = 37;
// Check quantity and display notice
if( $quantity > 1 && $targeted_product_id == $product_id ){
wc_add_notice( __('Only one item quantity allowed for this product', 'woocommerce' ), 'error' );
return false;
}
// Loop through cart items checking if the product is already in cart
foreach ( WC()->cart->get_cart() as $cart_item ){
if( $targeted_product_id == $product_id && $cart_item['data']->get_id() == $targeted_product_id ) {
wc_add_notice( __('This product is already in cart (only one item is allowed).', 'woocommerce' ), 'error' );
return false;
}
}
return $passed;
}
// Checking and removing quantity field for a specific product
add_filter( 'woocommerce_quantity_input_args', 'custom_quantity_input_args', 10, 2 );
function custom_quantity_input_args( $args, $product ) {
// HERE define your product ID
$targeted_product_id = 37;
if( $targeted_product_id == $product->get_id() )
$args['min_value'] = $args['max_value'] = $args['input_value'] = 1;
return $args;
}
Code goes in function.php file of your active child theme (or active theme). Tested and works.
I would like Woocommerce to only allow 1 product in the cart. If a product is already in the cart and another one is added then it should remove the previous one.
I found this code on net:
/**
* When an item is added to the cart, remove other products
*/
function custom_maybe_empty_cart( $valid, $product_id, $quantity ) {
if( ! empty ( WC()->cart->get_cart() ) && $valid ){
WC()->cart->empty_cart();
wc_add_notice( 'Only allowed 1 item in cart, please remove previous
item.', 'error' ); // here instead popup notice need to remove prevous added product
}
return $valid;
}
add_filter( 'woocommerce_add_to_cart_validation', 'custom_maybe_empty_cart',
10, 3 );
But it seems that is not working as I wanted. It need to autoremove previously added product in cart, and add latest added product in cart. Can someone to give me tip what need to update on class to work in latest woo 3.3.X ?
This one is the more compact and actual code as global $woocommerce is not needed anymore:
add_filter( 'woocommerce_add_to_cart_validation', 'auto_empty_cart', 20, 3 );
function auto_empty_cart( $passed, $product_id, $quantity ) {
if( WC()->cart->is_empty() ) return $passed; // Exit
WC()->cart->empty_cart();
return $passed;
}
Code goes in function.php file of your active child theme (or active theme).
Tested and works in all Woocommerce versions since 2.6.x
This working perfecty on Woocommerce 3.3.X
add_filter( 'woocommerce_add_to_cart_validation',
'bbloomer_only_one_in_cart', 99, 2 );
function bbloomer_only_one_in_cart( $passed, $added_product_id ) {
global $woocommerce;
// empty cart: new item will replace previous
$woocommerce->cart->empty_cart();
// display a message if you like
wc_add_notice( 'Product added to cart!', 'notice' );
return $passed;
}
I am trying to change product price in cart using the following function:
add_action( 'woocommerce_before_shipping_calculator', 'add_custom_price'
);
function add_custom_price( $cart_object ) {
foreach ( $cart_object->cart_contents as $key => $value ) {
$value['data']->price = 400;
}
}
It was working correctly in WooCommerce version 2.6.x but not working anymore in version 3.0+
How can I make it work in WooCommerce Version 3.0+?
Thanks.
Update 2021 (Handling mini cart custom item price)
With WooCommerce version 3.0+ you need:
To use woocommerce_before_calculate_totals hook instead.
To use WC_Cart get_cart() method instead
To use WC_product set_price() method instead
Here is the code:
// Set custom cart item price
add_action( 'woocommerce_before_calculate_totals', 'add_custom_price', 1000, 1);
function add_custom_price( $cart ) {
// This is necessary for WC 3.0+
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;
// Avoiding hook repetition (when using price calculations for example | optional)
if ( did_action( 'woocommerce_before_calculate_totals' ) >= 2 )
return;
// Loop through cart items
foreach ( $cart->get_cart() as $cart_item ) {
$cart_item['data']->set_price( 40 );
}
}
And for mini cart (update):
// Mini cart: Display custom price
add_filter( 'woocommerce_cart_item_price', 'filter_cart_item_price', 10, 3 );
function filter_cart_item_price( $price_html, $cart_item, $cart_item_key ) {
if( isset( $cart_item['custom_price'] ) ) {
$args = array( 'price' => 40 );
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_html;
}
Code goes in functions.php file of your active child theme (or active theme).
This code is tested and works (still works on WooCommerce 5.1.x).
Note: you can increase the hook priority from 20 to 1000 (or even 2000) when using some few specific plugins or others customizations.

I tried priority values of 10,99 and 999 but the price and total in my cart did not change (even though I was able to confirm with get_price() that set_price() had actually set the price of the item.
I have a custom hook that adds a fee to my cart and I'm using a 3rd party plugin that adds product attributes. I suspect that these WooCommerce "add-ons" introduce delays that require me to delay my custom action.
