Have an error in my PayPal module on my Prestashop site. It says

[30-Oct-2018 10:37:19 Australia/Sydney] PHP Notice: A non well formed numeric value encountered in /home/public_html/modules/npaypalpro/ajax.php on line 214

Line 214 is

$amountCheck += number_format($item['quantity'] * $item['price'], 2);

Any ideas what might be the cause?

PHP7.1 on the server

PayPal said

I quickly checked the transaction logs and found that there is mismatch in total amount and item amount.

For one of the order, total amount is AUD 2337.30 but the sum of item
details are AUD 2339.30

Item Details :

Hikvision 6 MB - 180.90 x 7(quantity) = 1266.30 AUD Hikvisiion 4
channel - 535.50 x 2(quantity) = 1071.00 AUD Shipping – 0 Voucher
Taxes – 2.00 AUD – Which is not added in the total amount.

Could you please ask the web developer to check how Voucher taxes are
getting added or to see why this is not passing in the API call?

Full function

function totalAmountCheck($amount, $items)

{

    $amountCheck = $diff = 0;



foreach ($items as $item)

    $amountCheck += number_format($item['quantity'] * $item['price'], 2);



if ($amountCheck != $amount)

    $diff = number_format($amountCheck - $amount, 2);



return $diff;

}

The problem is the format of the content in the variables, you can solve it by replacing it with this:
$amountCheck += number_format((int)$item['quantity'] * (float)$item['price'], 2);

Paypal wants the exact price.

For example:

If your cart is 25 euro for 2 products plus 5 euro of shipping, you must to passing the shipping too.

in this case you must to pass the Voucher Taxes.

Paypal say: you want 2339.30 AUD but your cart is 2 AUD less.
