Interesting issue here...don't know where the problem is because I am using the code from another site that I have. The first site works perfectly and no problems...but when I converted it over to my new site, the total price amount won't calculate properly.
QUESTION: Am I missing something when I switched over my code? If I put the code below into the while loop it works ok with only ONE item, but not multiple and it doesn't look right if I change the location to this.
<div class="column text-lg">Subtotal: <span class="text-medium">$<?php echo $totalamount; ?></span></div>
Here is some images and the code that I have:
OLD WORKING CODE:
<?php
if ( ! isset($totalamount)) {
$totalamount=0;
}
$totalquantity=0;
if (!session_id()) {
session_start();
}
include ('core/connectdb.php');
$sessid = session_id();
$query = "SELECT * FROM cart WHERE cart_sess = '$sessid'";
$results = mysqli_query($connect, $query) or die (mysql_query());
if(mysqli_num_rows($results)==0)
{
echo '<div id="content" class="float_r"><div align="center"><h3>Your cart is empty.</h3> You can find our items on our <a href="products.php">product page</a>.</div></div><div class="cleaner"></div>';
}
else
{
?>
<div id="content" class="float_r">
<div align="center"><h1>Shopping Cart</h1></div>
<table border="1" align="center" cellpadding="5">
<tr><td> Item Code</td><td>Quantity</td><td>Item Name</td><td>Price</
td><td>Total Price</td>
<?php
while ($row = mysqli_fetch_array($results, MYSQLI_ASSOC)) {
extract($row);
echo "<tr><td>";
echo $cart_itemcode;
echo "</td>";
echo "<td><form method=\"POST\" action=\"cart.php?action=change&icode=
$cart_itemcode\"><input type=\"text\" name=\"modified_quantity\" size=\"2\"
value=\"$cart_quantity\">";
echo "</td><td>";
echo $cart_item_name;
echo "</td><td>";
echo '$' . $cart_price . '';
echo "</td><td>";
$totalquantity = $totalquantity + $cart_quantity;
$totalprice = number_format($cart_price * $cart_quantity, 2);
$totalamount=$totalamount + ($cart_price * $cart_quantity);
echo '$' . $totalprice . '';
echo "</td><td>";
echo "<input type=\"submit\" name=\"Submit\" value=\"Change quantity\">
</form></td>";
echo "<td>";
echo "<form method=\"POST\" action=\"cart.php?action=delete&icode=$cart_itemcode\">";
echo "<input type=\"submit\" name=\"Submit\" value=\"Delete Item\"></form>
</td></tr>";
}
echo "<tr><td >Total</td><td>$totalquantity</td><td></td><td></td><td>";
$totalamount = number_format($totalamount, 2);
echo '$' . $totalamount . '';
echo "</td></tr>";
echo "</table><br>";
echo "<div style=\"width:400px; margin:auto;\">You currently have " .
$totalquantity . " product(s) selected in your cart</div> ";
?>
