[Resolved] Adding up dynamic variables

dmacman1962

Hi All,

I have a post that is resolved and works great, but I just thought of having PHP add up the total of all the items ordered from this post My post that is resolved .

Here is another post that show how to do this, but I cannot seem to apply this technique to my code. Previous Add variable link

Here is the code I have form my process page.

<html> 
<head><title>process.php</title></head> 
<body> 
<?php if(isset($_POST['order'])){    ?>  

    <table border="1" cellpadding="2" cellspacing="0"> 
        <tr> 
            <th>ID</th> 
            <th>Item</th> 
            <th>Quantity</th>
		    <th>Price</th> 

    </tr> 
<?php    foreach($_POST['order'] as $key => $ID) { ?>  

        <tr> 
            <td><?php echo $ID; ?></td> 
            <td><?php echo $_POST['name_'.$ID]; ?></td> 
            <td><?php echo $_POST['quantity_'.$ID]; ?></td> 
			<td><?php echo $_POST['price_'.$ID]; ?></td> 
        </tr> 
<?php     } ?>  

    </table> 
<?php }   ?>
</body> 
</html>

I know I am close with this process page, and this may be very easy for you to resolve, but I am a little confused here.

Thanks a bunch,

Don

I figured this out. Here is the code:


<html> 
<head><title>process.php</title></head> 
<body> 
<?php if(isset($_POST['order'])){    ?>  

    <table border="1" cellpadding="2" cellspacing="0"> 
        <tr> 
            <th>ID</th> 
            <th>Item</th> 
            <th>Quantity</th>
		    <th>Price</th> 

    </tr> 
<?php    foreach($_POST['order'] as $key => $ID) { ?>  

        <tr> 
            <td><?php echo $ID; ?></td> 
            <td><?php echo $_POST['name_'.$ID]; ?></td> 
            <td><?php echo $_POST['quantity_'.$ID]; ?></td> 
			<td><?php echo $_POST['price_'.$ID]; ?></td> 
        </tr> 
<?php     } ?>  

    </table> 
<?php }   ?>
<?php  

foreach($_POST['order'] as $key => $ID){ 
   $total += ${'price_'.$ID}; 
}
echo "The Total is $"."$total<br>";
?>
</body> 
</html>

It's true. If you hang around people smarter than you, you get smarter yourself!!! 😃

Thanks all,

Don
