Add value of the check box to PHP result?

I have a PHP shopping cart which is very simple and it works as it should.

However what i want to do is to add two checkboxes in the shopping cart with two different values for shipping costs.

for example one has a value of 7 and one has a value of 12.

I have this PHP in my shopping cart:

$totalAll = $totalAll + ($item['qty']*$item['price']) + 'ship';

And i echo the $totalAll like this:

<?php echo $totalAll;?>

I have these two checkboxes too:

<label>UK Shipping</label>
<input name="ship" type="checkbox" value="7" />

    <label>International Shipping</label>
<input name="ship" type="checkbox" value="12" />

so I need the $totalAll + 'ship' value but the way i did it doesn't really make sense!

could someone help me out with this please?

Thanks

I'd suggest you to use radio buttons instead of check boxes and store the shipping values on the server. This results in something like this:

$shipping = array(
    1 => 7,
    2 => 12
);

// nothing selected?
if (!isset($_REQUEST['ship'])) {
    die("error"); // your error handling..
}
$ship = $shipping[(int) $_REQUEST['ship']];

and the html

<label>UK Shipping</label>
<input name="ship" type="radio" value="1" />

<label>International Shipping</label>
<input name="ship" type="radio" value="2" />

You can use radio instead of checkbox:

<label for="uk">UK Shipping</label>
<input id="uk" name="ship" type="radio" value="7" />

<label for="international">International Shipping</label>
<input id="international" name="ship" type="radio" value="12" />

First of all, i would recommend radio buttons. It doesnt make sense to add both kinds of shipping costs.

Second, adding "ship" to a number wont help you. You need the following in your receiveform (in my case test.php):

HTML:

<form method="post" action="test.php" enctype="multipart/form-data">
    <input type="radio" name="ship" value="7">
    <input type="radio" name="ship" value="12">
    <input type="submit">
</form>

test.php:

$ship = $_POST['ship'];
$total = $totalAll + $ship;

This will give you the full price.

Dont forget to validate input! In general, its not a good practice to rely on the HTML form for calculating prices.

HTML

<label>UK Shipping</label>
<input name="ship[]" type="checkbox" value="7" />

    <label>International Shipping</label>
<input name="ship[]" type="checkbox" value="12" />

PHP

   $ship = 0;
   foreach($_POST['ship'] as $s)
   {
      $ship += $s;
   }
   $totalAll += ($item['qty']*$item['price']) + $ship;
