Question

I have a big time trying to either convert a string into a integer or multiply two integers. I can’t convert the string into integer because it’s resulting me into a boolean (when I’m using var_dump). I can convert the other integer in string, but I’m unable to multiply it.

I have this:

    <? $fees=$commerce->cart->get_total(); 
    $payfee = str_replace('&nbsp;&euro;', '', $fees);
    $payfee = str_replace(',','', $payfee);  //this is the string
    $fee = 0.025;
    $paypal = $payfee * $fee;  //this thing is not working

    ?>

I tried converting the payfee in integer, but still can’t make it work. I did something like this before and worked well, but not this time.

Any help will be appreciated.

P.S Thank you to the whole stackoverflow.com community which helped me many times before.

Answer 1

OP is running WooCommerce, and his $commerce->cart->get_total();
function responds output such as <span class="amount">560&nbsp;&euro;</span> (560 €)
and he’s asking how to convert this to a number so he can get a fee
(2.5 %) from the amount.

First of all, the problem here is that the get_total() function responds with a string.

The correct way to fix this string would be a simple example such as

<?php
    $totalAmountString = $commerce->cart->get_total(); //<span class="amount">560&nbsp;&euro;</span>
    $totalAmountString = strip_tags($totalAmountString); //get rid of the span - we're left with "560&nbsp;&euro;"
    $totalAmountString = str_replace(array("&nbsp;&euro;", ","), "", $totalAmountString);
    $totalAmountFloat = (float)$totalAmountString;
    $fee = 0.025;
    $feeForThisAmount = $totalAmountFloat * $fee;
    var_dump($feeForThisAmount);

    $totalAmountWithFee = $totalAmountFloat + $feeForThisAmount;
    var_dump($totalAmountWithFee);
?>

However, according to the Woo Commerce API Documentation you should be able to use $commerce->cart->total to get a float of the number, so a solution that might also work (again, I know nothing about WooCommerce), would be the following:

<?php
    $totalAmountFloat = $commerce->cart->total;
    $fee = 0.025;
    $feeForThisAmount = $totalAmountFloat * $fee;
    var_dump($feeForThisAmount);

    $totalAmountWithFee = $totalAmountFloat + $feeForThisAmount;
    var_dump($totalAmountWithFee);
?>

Edit

According to your latest data dump, the problem is that you’re using

$paypal_fees=$woocommerce->cart->get_total() * 0.025;

where you should be using

$paypal_fees=$woocommerce->cart->total * 0.025;

as ->get_total() receives a string, and ->total receives a float.
