Hi,
Ok I am currently making a shopping cart and have a problem. I am using cookies to keep track of a users shopping cart and when they add an item, I need it to redirect them to the product the just ordered but also, to show a little summary of their cart on the page. Now this is the code I am using:
$product = $_REQUEST['pid'];
$quantity = 1;
$cart = new Cart($cart_id);
$cart->add_item($product, $quantity);
echo "<h2>Item Added to Shopping Basket</h2>";
echo "<p>Thank you for adding the item to your shopping basket.</p>";
echo "<p><a href=\"index.php?section=Checkout\">Checkout</a> or ";
echo "<a href=\"".$_SERVER['HTTP_REFERER']."\">go back to previous product.</a></p>";
Now, the above code kicks in when the user clicks the Add to Basket button.
This is some of the class I am using that you saw initiated above:
// Add item to cart
function add_item($product, $quantity) {
// Select data for product
$query = "SELECT fld_quantity FROM " . $this->inv_table .
" WHERE fld_pid='$product'";
$result = mysql_query($query, $this->dblink);
$row = mysql_fetch_array($result);
// Quantity greater than stock level
if($quantity > $row['fld_quantity']) return false;
mysql_free_result($result);
// Check not ordering more than total amount
$qty = $this->check_item($product);
// Product not already added to cart, add new
if($qty == 0) {
// Insert into database
$query = "INSERT INTO ".$this->cart_table
. " (fld_id, fld_pid, fld_cartid, fld_amount, fld_date, fld_time) VALUES ";
$query .= "('', '$product', '".$this->cart_id."', '$quantity',CURRENT_DATE(), CURRENT_TIME()) ";
mysql_query($query, $this->dblink);
} else { // Product already added to cart, update quantity for that product
// Add one to quantity
$quantity += $qty;
// Update database
$query = "UPDATE ".$this->cart_table .
" SET fld_amount='$quantity' WHERE fld_cartid='".$this->cart_id."' AND ";
$query .= "fld_pid='$product' ";
mysql_query($query, $this->dblink);
}
return true;
}
This is the cookie being set for $cart_id:
// no cookie set for cart
if(!isset($HTTP_COOKIE_VARS['DCP_Cart'])) {
// create random cart id
$cart_id = md5(uniqid(rand()));
// set cookie for cart
setcookie("DCP_Cart", $cart_id, time() + 14400);
// cart cookie already set, use it
} else {
$cart_id = $HTTP_COOKIE_VARS['DCP_Cart'];
}
This is the script that shows if something has been added to the cart:
<?
// check to see if there are items in the users cart
$cart = new Cart($cart_id);
if ($cart->num_items() > 0) { ?>
<img src="../_img/img_cart.jpg" alt=" " width="17" height="34" title=" "/><br />
</br><a href="#"> <? echo _txt_VALIDATEORDER_; ?></a>
<? } ?>
Any ideas on how to get this to show as soon as I add a product...the problem seems to be where I say thankyou, I would like to have a refresh of the page there but I can't do it with the PHP Location function as it's not at the top of the page and it gives me errors about headers already being sent.
Anyone think of a better way to update this?
Cheers,
Chris
