WebStyles Posted August 9, 2011 Share Posted August 9, 2011 when you create the cart: //RUN IF THE CART IS EMPTY OR NOT SET $_SESSION["cart_array"] = array(1 => array("item id" => $pid, "quantity" => 1)); you're using 'item id', but then you want to see it, you add an underscore: 'item_id'... that's why it says your variable is not defined. you're using the wrong name.

phpSensei Posted August 9, 2011 Share Posted August 9, 2011 Whats the point of while ($row = mysql_fetch_array($sql)){ $product_name = $row["product_name"]; $price = $row["price"]; } inside your loop?

CASHOUT Posted August 9, 2011 Author Share Posted August 9, 2011 PHP Sensei while ($row = mysql_fetch_array($sql)){ $product_name = $row["product_name"]; $price = $row["price"]; } this piece of code is so that, when an item is added to the cart, the product name and price is fetched from the mysql database and displayed on the shopping cart list Quote Link to comment https://forums.phpfreaks.com/topic/244292-shopping-cart-issues/#findComment-1254842 Share on other sites More sharing options...
