Hello,
I have created a custom code to have different choice of quantity and implant a shortcode on the product page to set different add to cart. The calculation of the amount in the cart page is : product_price*quantity*"a meta field".
My code work perfectly for the USD (base currency), but for EUR, secondary currency, it does not take the meta field in consideration.
Could you help to understand why the secondary currency can not work with our code :
// Add Shortcode
function custom_product_purchase_shortcode() {
global $product;
if (!$product->is_type('simple')) {
return; // Only simple products are supported
}
ob_start();
?>
<form class="custom-product-purchase-form" method="post">
<input type="hidden" name="add_to_cart" value="<?php echo esc_attr($product->get_id()); ?>">
<input type="hidden" name="product_id" value="<?php echo esc_attr($product->get_id()); ?>">
<p>
<label for="pallet_quantity">Pallet Quantity:</label>
<input type="number" id="pallet_quantity" name="pallet_quantity" value="1" min="1">
</p>
<p>
<button type="submit" class="button alt" name="pallet_submit">Add to Cart (Pallet)</button>

</form>
<form class="custom-product-purchase-form" method="post">

<p>

Hello
To convert a custom number, please use - https://currency-switcher.com/function/woocs-woocs_exchange_value
https://share.pluginus.net/image/i20240216104923.png - In this part of the code you should take into account that the price should be set only in the base currency. So if you counted amounts in another currency to the set_price function, you must pass the amount in the base currency. Example of conversion to base currency:
$currrent = $WOOCS->current_currency;
if ($currrent != $WOOCS->default_currency) {
$currencies = $WOOCS->get_currencies();
$rate = $currencies[$currrent]['rate'];
$your_any_price = $your_any_price / $rate;
}
Thank you very much Pablo.
The second currency (EUR) is already set on the product by the vendor, so just wondering if we need to try to convert the price or just pick up the price already set in EUR in backend by the vendor ?
All prices must be stored in the base currency
I tried like this, but it doesnt work :
// Adjust cart totals based on WCFM field value
function modify_cart_totals($cart) {
if (is_admin() && !defined('DOING_AJAX')) return;
global $WOOCS;
foreach ($cart->get_cart() as $cart_item_key => $cart_item) {
$product = $cart_item['data'];
$product_id = $product->get_id();
$quantity = $cart_item['quantity'];
// Check if the product has the custom field and it's not empty
if (isset($cart_item['quantity_pallet']) && !empty($cart_item['quantity_pallet'])) {
$price_multiplier = $cart_item['quantity_pallet'];
} else {
// If the custom field is empty, remove the item from the cart
$cart->remove_cart_item($cart_item_key);
continue; // Skip to the next cart item
}
// Get product price
$product_price = $product->get_price();
// Calculate total price for the item including the price multiplier
$total_price = $product_price * $quantity * $price_multiplier;
// Convert total price to base currency if necessary
$current_currency = $WOOCS->current_currency;
if ($current_currency != $WOOCS->default_currency) {
$currencies = $WOOCS->get_currencies();
$rate = $currencies[$current_currency]['rate'];
$total_price = $total_price / $rate;
}
// Set total price to the cart item
$cart_item['data']->set_price($total_price);
}
}
add_action('woocommerce_before_calculate_totals', 'modify_cart_totals', 10, 1);
Hello
describe in more detail what does not work
Hello Pablo,
I see that the field value is not multiply with the unit price * quantity.
The rules of this code works like this (and its work for the base currency USD but not for secondary EUR) :
- The client add the predefined quantity (for example pallet), the number inside the pallet quantity is set in advance in a field named 'pallet_quantity'. So the calculation for the cart and checkout is : Unit Price * quantity * field (pallet_quantity). This is working perfectly for the USD
- For the EUR, we can see that the field is not taken in consideration in the cart and checkout page. Its only taken the Unit price*quantity and the the field that is the base value of the product quantity in 1 pallet. The unit price of the product in EUR is working, its well the one already set. But it seems woocs plugin, doesnt want to take the field that is necessary for our calculation
do you use fixed prices?
yes i do
Hello
Ok! Turn it off and do a test
The point is that the meaning of a fixed price is a price that does not change
Hello Pablo,
I just tried to turn off the fix priced, effectively it's working. But the issue we need to define the EUR price in advance with the fixed price in our case.
"The point is that the meaning of a fixed price is a price that does not change" : when we multiply the unit price in our * quantity (of pallet) * field (number of unit on a pallet), in that case we do not change the fixed unit price, only the quantity ordered. The field is only giving a number that is not price changing, this is only a quantity that we will multiply to the unit price
The only option is to use this hook - https://currency-switcher.com/hook/woocs_fixed_raw_woocommerce_price
Thanks, i'm trying since yesterday, but don't find the right way at the moment with this hook
Hello
This hook passes the fixed price and product object. If you determine the current position in the cart or checkout, you can change the fixed price
