Contact Form - Display items in body of email issues - php

Question

I am having an issue with my contact form and need help with the code.
Here is an image of the "cart", user can add/remove items from the table.
Once they have selected all the products they want, in this example I have added 2 items, they then click the order form button and a form pops up to the left that displays both items.
My problem is that when the email comes through it only displays the last item and not both items from the form, this is what it looks like in the email
How do I make it so that it pulls through both items or all items from the form on the left into the body of my email.
Below is my code, if someone can look through and advise what I must change or what I am doing wrong.
<section class="order">
<?php
$id = isset($_GET['id']) ? (int) $_GET['id'] : 0;
$sql = $con->prepare("SELECT * FROM products WHERE product_id = ?");
$sql->bind_param("i", $id);
$sql->execute();
$result = $sql->get_result();
$rows = $result->num_rows;
{
while($row = $result->fetch_assoc())
{
?>
<div class="product-info">
<form method="post" action="cart.php?action=add&id=<?php echo $row["product_id"]; ?>">
<img src="images/<?php echo $row["image"]; ?>" class="image" /><br /><br>

Your help would be greatly appreciated :)

Answer 1

The fault lies here:
if (isset($_POST['submit'])) {
$name = $_POST['name'];
$subject = $_POST['subject'];
$mailFrom = $_POST['mail'];
$number = $_POST['number'];
$product = $_POST['productname'];
$description = $_POST['description'];
$code = $_POST['code'];
$qty = $_POST['qty'];
$mailTo = "email#example.co.za";
$headers = "From: " . $mailFrom;
$txt = "You have received an e-mail from " . $name . ".\n\n" . "Email address: " . $mailFrom . ".\n\n" . "Contact number: " . $number . ".\n\n" . "Order Details:\n\n" . $product . ".\n\n" . "Description:" . $description . ".\n\n" . "Product Code:" . $code . ".\n\n" . "Quantity Ordered:" . $qty;
mail($mailTo, $subject, $txt, $headers);
header("Location: cart.php?mailsend");
}
The $txt variable is responsible for the text in the Email and you are setting its value to the last order posted via the form. You have to concatenate every order. So, you have to do something like $txt .= "You...." Use the (.) operator to concatenate product details every time
