Losing decimals in Qty column on PayPal page

[ghost]

Hello,

Thank you for this plugin!

I'm having an issue where the quantity looks fine in the invoice but when you click the pay link in the email that redirects to PayPal it's it loses all the decimal places. The value shown to pay on the PayPal payment page is as if the values entered into the invoice had no decimal values at all. Hope that makes sense.

Any ideas?

Thanks!

Actually, looky here it looks like they have actually added the filter mentioned: https://github.com/woocommerce/woocommerce/blob/master/includes/gateways/paypal/includes/class-wc-gateway-paypal-request.php#L337

i know is a bit older but here

add_filter('woocommerce_paypal_line_item',  function ($item, $item_name, $quantity, $amount) {

	if (is_float($quantity)) {
		$item['quantity'] = $quantity;
	}

	return $item;
},10,4);

add_filter( 'woocommerce_paypal_args', function ( $args) {

	{
		global $woocommerce;

		$cart_items = $woocommerce->cart->get_cart();

		foreach ( $args as $key => $arg ) {
			if ( preg_match( '/quantity_/', $key ) ) {
				$index = substr( $key, 9 );
				if ( is_int( $args[ 'quantity_' . $index ] ) ) {
					foreach ( $cart_items as $item ) {
						$productMetaNamePayPalKey = get_product_meta_key( $item );
						$productMetaNamePayPal    = $productMetaNamePayPalKey;
						if ( ! is_int( $item['quantity'] ) &&
						     $args[ 'item_name_' . $index ] == $productMetaNamePayPal &&
						     (int) $item['quantity'] == $args[ 'quantity_' . $index ] &&
						     (float) $item['data']->price == $args[ 'amount_' . $index ]
						) {
							$quantity_suffix              = ''; //here you can add suffix when you want
							$args[ 'quantity_' . $index ] = $item['quantity'];
						}
					}
				}
				if ( ! is_int( $args[ 'quantity_' . $index ] ) ) {
					$args[ 'amount_' . $index ]    = round( $args[ 'amount_' . $index ] * $args[ 'quantity_' . $index ], 2 );
					$args[ 'item_name_' . $index ] = get_new_product_name( $args, $index, isset( $quantity_suffix ) ? $quantity_suffix : '' );
					$args[ 'quantity_' . $index ]  = 1;
				}
			}
		}


		return $args;
	}
}, 10, 2 );

function get_product_meta_key( $item ) {
	if ( ! empty( $item['variation_id'] ) ) {
		return $item['variation_id'];
	} else {
		return $item['product_id'];
	}
}

function get_new_product_name( $args, $index, $quantity_suffix = null ) {

	if ( ! empty( $quantity_suffix ) ) {
		return $args[ 'item_name_' . $index ] . ' x ' . $args[ 'quantity_' . $index ] . ' ' . $quantity_suffix;
	}

	return $args[ 'item_name_' . $index ] . ' x ' . $args[ 'quantity_' . $index ];
}

this solved the issue for me
