I have the same issue with versions 42.2 and 42.1. The “redirect to front page” error occurs when trying to access /wp-admin or when clicking “Sign in with Microsoft”. Instead of redirecting to Microsoft login, the site redirects back to the homepage. Because of this, I downgraded to version 42.0, and that version works correctly.

Please fix this issue ASAP @wpo365

Thanks, Simon

Hi @19db ,

Thank you for pointing out the importance of considering multiple VAT rates in the cart. To address this, I’ve updated the code to dynamically calculate a weighted VAT percentage based on the items in the cart. This ensures that the VAT applied to the wallet deduction is accurate even when there are multiple tax rates involved.

add_action('woocommerce_cart_calculate_fees', function ($cart) {
	if (is_admin() && !defined('DOING_AJAX')) {
		return;
	}

	foreach ($cart->get_fees() as $fee) {
		if (isset($fee->id) && strpos($fee->id, 'wallet') !== false) {
			$original_fee_amount = $fee->amount; // Original net wallet deduction
			$total_vat_percentage = 0;
			$total_cart_net = 0;

			// Calculate weighted VAT percentage based on cart items
			foreach ($cart->get_cart() as $cart_item) {
				$product = $cart_item['data'];
				$tax_class = $product->get_tax_class(); // Product tax class
				$tax_rates = WC_Tax::get_rates($tax_class); // Tax rates based on tax class

				// Get the tax rate
				$tax_rate = !empty($tax_rates) ? array_shift($tax_rates) : null;
				$vat_percentage = isset($tax_rate['rate']) ? floatval($tax_rate['rate']) : 0;

				// Net price of the product item
				$product_price_net = $cart_item['line_total'];
				$total_cart_net += $product_price_net;

				// Add to weighted VAT percentage
				$total_vat_percentage += ($product_price_net / $cart->get_subtotal()) * $vat_percentage;
			}

			// Apply the weighted VAT percentage to the wallet deduction amount
			$fee->amount = $original_fee_amount * (1 + ($total_vat_percentage / 100));
			$fee->total = $fee->amount;

			// Debugging data
			$debug_data = [
				'fee' => [
					'fee_id' => $fee->id,
					'original_amount' => $original_fee_amount,
					'new_amount_with_vat' => $fee->amount,
				],
				'weighted_vat_percentage' => $total_vat_percentage,
				'total_cart_net' => $total_cart_net,
			];
			error_log(print_r($debug_data, true)); // Debug log for further analysis
		}
	}
}, 9999);

Explanation:

1. Weighted VAT Percentage: The VAT percentage is calculated dynamically as a weighted average based on the net price of each cart item, ensuring that mixed VAT rates are handled accurately.
2. Dynamic Wallet Deduction Adjustment: The wallet deduction (fee) is adjusted to include the weighted VAT, ensuring the gross value of the wallet is deducted correctly from the cart total.
3. Debugging: The code includes an error log (error_log) that records the calculations, including the original fee amount, the weighted VAT percentage, and the final adjusted fee amount, to verify the results.

Note: This code only works correctly when combined with the following WooCommerce modification:
/woocommerce/includes/class-wc-cart-totals.php

$max_discount = round( $this->get_total( 'items_total', true ) + $fee_running_total + $this->get_total( 'shipping_total', true ) + array_sum( $this->get_tax_class_costs() ) ) * -1;

This approach ensures that the VAT calculations are accurate and consistent for carts with multiple VAT rates.

@subratamal , could you please contact the WooCommerce support team to address these calculation issues and explain the problem? Additionally, it would be great if you could consider integrating my code into the plugin to ensure accurate VAT calculations.

Best regards,
Simon

I am experiencing a similar issue with the WooWallet plugin. The wallet balance is displayed correctly in the info window, but when applied during checkout, the deducted amount does not match the announced gross value. Instead, the deduction seems to be based on the net value, leading to inconsistencies in the final cart totals.

For example:

• Wallet balance: 10 € (Gross)
• Expected deduction: -10 €
• Actual deduction: -8.40 € (Net)

This issue becomes even more apparent when the cart total is close to the available wallet balance. The system seems to incorrectly calculate the deduction based on the net value of the wallet, even though the gross value was announced in the info window.

Can you confirm if the current logic refers to the net value of the cart instead of the gross value during calculation? If so, could the logic be updated to ensure that the gross wallet balance is applied consistently without modifying the cart VAT amount?

Thank you for your help!

Best regards,
Simon
