To change the recurring price of a YITH Subscription on the WooCommerce cart using code, you'll need to tap into WooCommerce and YITH Subscription hooks and filters. Here’s a detailed guide on how to achieve this:
Steps to Change the Recurring Price in WooCommerce Cart
Understand the Structure:
- YITH WooCommerce Subscription plugin creates subscription products with recurring prices.
- You need to target the recurring price in the cart and adjust it as necessary.
Add Custom Code to Your Theme:
- You should add custom code to your theme's
functions.phpfile or create a custom plugin to avoid losing changes when updating the theme.
- You should add custom code to your theme's
Use Filters to Modify the Recurring Price:
- Use hooks provided by WooCommerce and YITH to modify the recurring price.
Code Example
Here’s a code example to modify the recurring price for YITH Subscription products in the WooCommerce cart:
Example
add_action('woocommerce_before_calculate_totals', 'change_recurring_price_in_cart', 20, 1);
function change_recurring_price_in_cart($cart) {
// Check if cart is empty
if (is_admin() && !defined('DOING_AJAX')) return;
// Loop through cart items
foreach ($cart->get_cart() as $cart_item_key => $cart_item) {
// Check if item is a subscription product
if (isset($cart_item['data']) && $cart_item['data'] instanceof WC_Product_Subscription) {
$product = $cart_item['data'];
// Get the current subscription price
$subscription_price = $product->get_price();
// Calculate the new recurring price
$new_recurring_price = $subscription_price * 1.2; // For example, increase by 20%
// Set the new price for the cart item
$cart_item['data']->set_price($new_recurring_price);
}
}
}Explanation of the Code
Hook into WooCommerce Cart Calculation:
woocommerce_before_calculate_totals: This hook runs before the cart totals are calculated. It's a suitable place to modify item prices before they are displayed or processed.
Check if Cart is Empty:
- Ensures that the code doesn’t run in the admin area or during AJAX requests.
Loop Through Cart Items:
- Loop through each item in the cart to check if it’s a subscription product.
Check if Product is a Subscription:
- Use
instanceof WC_Product_Subscriptionto verify that the product is a subscription.
- Use
Modify the Recurring Price:
- Retrieve the current subscription price and apply your custom logic to calculate the new price.
- Use
$cart_item['data']->set_price($new_recurring_price);to set the new price.
Additional Considerations
- Testing: Make sure to test the code thoroughly in a staging environment before deploying it to production.
- Backup: Always back up your site before making changes to the code.
- Custom Plugin: For easier management and future updates, consider placing this code into a custom plugin rather than adding it to the theme’s
functions.php.
This example shows a simple way to modify recurring prices, but you can adapt the logic to meet more complex requirements or pricing rules as needed.
