For WooCommerce, I try to use the following 2 code snippets: The first one adds a "winter" product at 0 cost if the cart reaches €40. This works.
Then I have the second code snippet that if I add a "summer" coupon it should remove the "winter" product added by default earlier, but it doesn't, what am I doing wrong?
Based on Add free gifted product for a minimal cart amount in WooCommerce answer, here is my First working snippet:
// Add free gifted product for specific cart subtotal
add_action( 'woocommerce_before_calculate_totals', 'check_free_gifted_product' );
function check_free_gifted_product( $cart ) {
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;
// Settings
$free_product_id = 90;
$targeted_subtotal = 20;
$cart_subtotal = 0; // Initializing
// Loop through cart items (first loop)
foreach ( $cart->get_cart() as $cart_item_key => $cart_item ){
// When free product is is cart
if ( $free_product_id == $cart_item['product_id'] ) {
$free_key = $cart_item_key;
$free_qty = $cart_item['quantity'];
$cart_item['data']->set_price(0); // Optionally set the price to zero
} else {
$cart_subtotal += $cart_item['line_total'] + $cart_item['line_tax'];
}
}
// If subtotal match and free product is not already in cart, add it
if ( ! isset($free_key) && $cart_subtotal >= $targeted_subtotal ) {
$cart->add_to_cart( $free_product_id );
}
}
// Display free gifted product price to zero on minicart
add_filter( 'woocommerce_cart_item_price', 'change_minicart_free_gifted_item_price', 10, 3 );
function change_minicart_free_gifted_item_price( $price_html, $cart_item, $cart_item_key ) {
$free_product_id = 90;
if( $cart_item['product_id'] == $free_product_id ) {
return wc_price( 0 );
}
return $price_html;
}
second snippet not working
function remove_free_product($cart) {
/**
* This function removes a free product "winter" from the cart if a coupon "summer" is applied.
*
* Parameters:
* $cart (array): An array containing the cart items and their details
*
* Returns:
* array: The updated cart array
*/
try {
// Check if the cart is empty
if (empty($cart)) {
throw new Exception("Cart is empty");
}
// Check if the coupon "summer" is applied
$coupon_applied = false;
foreach ($cart as $item) {
if ($item['coupon'] == 'summer') {
$coupon_applied = true;
break;
}
}
// Remove the free product "winter" if the coupon "summer" is applied
if ($coupon_applied) {
foreach ($cart as $key => $item) {
if ($item['product'] == 'winter' && $item['price'] == 20) {
unset($cart[$key]);
break;
}
}
}
// Return the updated cart
return $cart;
} catch (Exception $e) {
// Log the error
error_log("Error: " . $e->getMessage());
return array();
}
}
or rather, nothing happens, it updates the cart if I enter the coupon "summer" but it doesn't remove "winter"
Tnx e.
