Hello everyone,
Let me first say that I am a PHP beginner. With the use of online video tutorials I have setup a shopping cart for my online store that sells stainless steel jewelry. Everything is working well, but I want to add something and even though I know what needs to e done - I don’t know how to go about it. Can someone please help me out?
So I have a product page that gets the product’s name, code, price and details from the database. This is the page’s code:
<?php
// Script Error Reporting
error_reporting(E_ALL);
ini_set('display_errors', '1');
?>
<?php
// Check to see the URL variable is set and that it exists in the database
if (isset($_GET['id'])) {
// Connect to the MySQL database
include "storescripts/connect_to_mysql.php";
$id = preg_replace('#[^0-9]#i', '', $_GET['id']);
// Use this var to check to see if this ID exists, if yes then get the product
// details, if no then exit this script and give message why
$sql = mysql_query("SELECT * FROM products WHERE id='$id' LIMIT 1");
$productCount = mysql_num_rows($sql); // count the output amount
if ($productCount > 0) {
// get all the product details
while($row = mysql_fetch_array($sql)){
$product_code = $row["product_code"];
$product_name = $row["product_name"];
$price = $row["price"];
$details = $row["details"];
$category = $row["category"];
$date_added = strftime("%b %d, %Y", strtotime($row["date_added"]));
}
} else {
echo "The item does not exist.";
exit();
}
} else {
echo "Data to render this page is missing.";
exit();
}
mysql_close();
?>

The product page looks like this: Product
You’ll notice I’ve added an “Engraving” label to the form. I want a visitor to be able to add the engraving they want to be done on this product. This information should then be sent to the cart with all the other details when the person adds the item to their cart. I want the text to be engraved to be displayed in the cart’s table with the image, price, etc. This output should be in the

Could someone please help me get the text to be engraved added to the cart? I would really appreciate it. It is probably very simple, but I’m completely stuck.
Thanks
