I am looking for function that can disable the quantity x item price in the cart page.
Normally if product price is €1 and quantity is 3 | Line item subtotal is €3… (1€ x 3).
Now I Would like to keep the product price without x quantity calculation like this:
Product price is €1 and quantity is 3 | Line item subtotal is €1
Does anybody a idea how to disable this quantity price calculation?
Yes it's possible to disable the quantity item prices calculation, but it's quite complicated…
The code:
// Custom line item Total/Subtotal price display
add_filter( 'woocommerce_cart_product_subtotal', 'custom_cart_subtotal', 10, 4 );
function custom_cart_subtotal( $product_subtotal, $product, $quantity, $wc_cart ) {
$price = $product->get_price();
$taxable = $product->is_taxable();
$quantity = 1; // HERE We set the quantity to 1 (So the price is calculated on a quantitity of 1)
// Taxable
if ( $taxable ) {
if ( 'excl' === $wc_cart->tax_display_cart ) {
$row_price = wc_get_price_excluding_tax( $product, array( 'qty' => $quantity ) );
$product_subtotal = wc_price( $row_price );
if ( $wc_cart->prices_include_tax && $wc_cart->tax_total > 0 ) {
$product_subtotal .= ' <small class="tax_label">' . WC()->countries->ex_tax_or_vat() . '</small>';
}
} else {
$row_price = wc_get_price_including_tax( $product, array( 'qty' => $quantity ) );
$product_subtotal = wc_price( $row_price );
if ( ! $wc_cart->prices_include_tax && $wc_cart->tax_total > 0 ) {
$product_subtotal .= ' <small class="tax_label">' . WC()->countries->inc_tax_or_vat() . '</small>';
}
}
} // Non-taxable
else {
$row_price = $price * $quantity;
$product_subtotal = wc_price( $row_price );
}
return $product_subtotal;
}
// Custom cart subtotal and totals (Prices calculated on quatity = 1)

Code goes in function.php file of your active child theme (or theme) or also in any plugin file.
Tested on WooCommerce 3+ and works (for prices including Tax or excluding Tax).
I havent test it with fees and discounts. So may be you should need some additional code...
