Question

I’ve a big problem:
When someone selects multiple products, for example he selects 3 products, it goes into the shopping cart. When he sends the order (checkout) I only see the first product in my mail, not 3.

This is because I have stated in function.js:

function fillInForm(){

    NumberOrdered = 0;
    NumberOrdered = readCookies("NumberOrdered");

    for (i = 1; i <= NumberOrdered; i++){
        NewOrder = "Order" + i;
        thisCookie = "";
        thisCookie = readCookies(NewOrder);;
        fields = new Array();
        fields = thisCookie.split("|");
        document.write("<input type=hidden name=\"Product ID " + i + "\" value=\"" + fields[0] + "\">");
        document.write("<input type=hidden name=\"Brand " + i + "\" value=\"" + fields[1] + "\">");
        document.write("<input type=hidden name=\"Model " + i + "\" value=\"" + fields[2] + "\">");
        document.write("<input type=hidden name=\"Price " + i + "\" value=\"" + fields[3] + "\">");
        document.write("<input type=hidden name=\"Amount products " + i + "\" value=\"" + fields[4] + "\">");
        document.write("<input type=hidden name=\"Total cost " + i + "\" value=\"" + fields[3] * fields[4] + "\">");
        document.write("<input type=hidden name=\" " + "\" value=\"" + "\">");

    }
}

when I use var_dump($_GET); it shows me everything, so the three products it shows me have
something like

["Brand_1"]=>
["Brand_2"]=>
["Brand_3"]=>

In mail.php where the information is send to I have:

$brand = $_GET["Brand_1"]; (<<WITH 1, one) 

because

$brand = $_GET["Brand_i"]; (<<WITH i) does not work.

But in theory I need

$brand = $_GET["Brand_i"] (<<WITH i)to get all the products............

How can I fix this?

mail.php

$productid = $_GET["Product_ID_1"];
$brand = $_GET["Brand_1"];
$model = $_GET["Model_1"];
$price = $_GET["Price_1"];
$amount = $_GET["Amount_products_1"];
$totalcost = $_GET["Total_cost_1"];

$message .= 'Your order information: ' . '<br />';
$message .= 'Product ID: ' . $productid . "<br />" .
            'Brand: '. $brand . "<br />" .
            'Model: ' . $model . "<br />" .
            'Price per item: ' . $price . "<br />" .
            'Amount of item: ' . $amount . "<br />" .
            'Total cost: ' . $totalcost . "<br />" .
            'Order date and time: ' . $date;
$message .= '</body></html>';

$message .= 'Your order information: ' . '<br />';
$i = 1;
while (isset($_GET["Product_ID_".$i])) {
    $productid = $_GET["Product_ID_".$i];
    $brand = $_GET["Brand_".$i];
    $model = $_GET["Model_".$i];
    $price = $_GET["Price_".$i];
    $amount = $_GET["Amount_products_".$i];
    $totalcost = $_GET["Total_cost_".$i];

    $message .= 'Product ID: ' . $productid . "<br />" .
                'Brand: '. $brand . "<br />" .
                'Model: ' . $model . "<br />" .
                'Price per item: ' . $price . "<br />" .
                'Amount of item: ' . $amount . "<br />" .
                'Total cost: ' . $totalcost . "<br />" .
    $i++;
}

$message .= 'Order date and time: ' . $date;
$message .= '</body></html>';
