I have tried for hours, and hope you can help me now :
I am trying to get values from a HTML form via $_POST
into a table via PHP, and multiplying two numbers: ['amount'] * ['price'] = $totalprice
So far so good.
I get something that might look like this:
Description – Amount – Format – Price – Total ($totalprice)
Spoon – 3 – pieces – 4 – 12
Plate – 2 – pieces – 3 – 6
Glass – 6 – pieces – 3 – 18
Now how do I sum up all the “Total” ($totalprice)’s
12+6+18 so I get the result: 36 ?
The piece of code I’m struggling with:
foreach($_POST['description'] as $value)
{
echo "<tr><td>";
echo $i+1;
echo "</td>
<td>".$value."</td>
<td><center>".$_POST['amount'][$i]."</td>
<td><center>".$_POST['format'][$i]."</td>
<td><center>".$_POST['price'][$i]."</td>";
//Figures out the total price = amount * price
$x1 = $_POST['amount'] [$i];
$x2 = $_POST['price'] [$i];
echo "<td><center>";
$totalprice = $x1 * $x2;
echo $totalprice;
//Figures out the total price = amount * price
$i++;
}
