PHP - Cart is not loading on the page

I have a website with a cart, the index file is as below:
<?php
session_start();
include_once 'product-action.php';
include_once 'cart.php';
$stmt = $conn->prepare("SELECT * FROM entertainment ORDER BY id ASC");
$stmt->execute();
$entertainment = $stmt->get_result();
echo '<table style="border: 1px solid #ddd;"><tr>';
if (!empty($entertainment)) {
foreach($entertainment as $product){
?>
<td style="border: 1px solid #ddd;">
<form method="post" action=""Location: " . "http://" . $_SERVER['HTTP_HOST'] . $location?action=add&id=<?php echo $product['id']; ?>">
<div class="product-image"><img src="<?php echo $product['image']; ?>" width="200" height="200"></div>
<div><strong><?php echo $product["title"]; ?></strong></div>
<div class="product-price"><?php echo "$".$product["offer_price"]; ?></div>
<div><input type="text" name="quantity" value="1" size="2" /><input type="submit" value="Add to cart" /></div>
</form>
</td>
<?php
}
}
echo '</tr></table>';
?>
The other 2 pages are as follows:
cart.php
<?php
if(!empty($_SESSION["cart_item"])){
$item_total = 0;
?>
<input type="button" value="Empty Cart">
<table cellpadding="10" cellspacing="1">
<tbody>
<tr>
<th><strong>Name</strong></th>
<th><strong>Quantity</strong></th>
<th><strong>Price</strong></th>
<th><strong>Action</strong></th>
</tr>
<?php
foreach ($_SESSION["cart_item"] as $item){
?>
<tr>
<td><strong><?php echo $item["product_title"]; ?></strong></td>
<td><?php echo $item["quantity"]; ?></td>
<td><?php echo "$".$item["price"]; ?></td>
<td>Remove Item</td>
</tr>
<?php
$item_total += ($item["price"]*$item["quantity"]);
}
?>
<tr>
<td colspan="3" align=right><strong>Total:</strong> <?php echo "$".$item_total; ?></td>

</tbody>
</table>
<?php
}
?>
<?php
if(!empty($_SESSION["cart_item"])){
$item_total = 0;

}
?>

<td colspan="3" align=right><strong>Total:</strong> <?php echo "$".$item_total; ?></td>

<?php
}
The product_action.php
<?php
if(!empty($_GET["action"])) {
$productId = isset($_GET['id']) ? htmlspecialchars($_GET['id']) : '';
$quantity = isset($_POST['quantity']) ? htmlspecialchars($_POST['quantity']) : '';
switch($_GET["action"]) {
case "add":
if(!empty($quantity)) {
$stmt = $conn->prepare("SELECT * FROM entertainment where id= ?");
$stmt->bind_param('i',$productId);
$stmt->execute();
$productDetails = $stmt->get_result()->fetch_object();
$itemArray = array($productDetails->id=>array('product_title'=>$productDetails->title, 'id'=>$productDetails->id, 'quantity'=>$quantity, 'price'=>$productDetails->offer_price));
if(!empty($_SESSION["cart_item"])) {
if(in_array($productDetails->id,array_keys($_SESSION["cart_item"]))) {
foreach($_SESSION["cart_item"] as $k => $v) {
if($productDetails->id == $k) {
if(empty($_SESSION["cart_item"][$k]["quantity"])) {
$_SESSION["cart_item"][$k]["quantity"] = 0;
}
$_SESSION["cart_item"][$k]["quantity"] += $quantity;
}
}
} else {
$_SESSION["cart_item"] = $_SESSION["cart_item"] + $itemArray;
}
} else {
$_SESSION["cart_item"] = $itemArray;
}
}
break;
case "remove":
if(!empty($_SESSION["cart_item"])) {
foreach($_SESSION["cart_item"] as $k => $v) {
if($productId == $v['id'])
unset($_SESSION["cart_item"][$k]);
}
}
break;
case "empty":
unset($_SESSION["cart_item"]);
break;
}
}
I am completely new to PHP. I tried searching alot but didn't find what I wanted. now the problem is while loading the page, the page is not displaying, its still loading. can anyone tell me how to fix it. any help would be great.

You can use Jquery date picker. Look at this https://jqueryui.com/datepicker/
You just need to use
("#inputField").Datepicker()
Place your html anywhere in the form.
The line above should go inside script> tag
Update You need to include jquery files like this in your page's header section
<link rel="stylesheet" href="//code.jquery.com/ui/1.11.4/themes/smoothness/jquery-ui.css">
<script src="//code.jquery.com/jquery-1.10.2.js"></script>
<script src="//code.jquery.com/ui/1.11.4/jquery-ui.js"></script>
<link rel="stylesheet" href="/resources/demos/style.css">

<?php
In this part im getting the correct answer in the database (the answer is a)
$correct_answer == $rows['answer'];
This score = score + 1; is not working
if ($correct_answer==$_POST[$rows['q_question']]){
$score = $score + 1;
}
?>
<?php
$connection=mysql_connect('localhost', 'root','');
mysql_select_db('thesis');

$query6 = mysql_query("SELECT * FROM student WHERE username='$username'");
$row6 = mysql_fetch_assoc($query6);
$s_id = $row6['id'];
$name = $row6['name'];
$email = $row6['email'];
$position = $row6['position'];
?>
This is where I get all the data needed in the results
<p hidden>
<input type="text" name="s_id" value="<?php echo $s_id ?>">
<input type="text" name="q_id" value="<?php echo $rows['q_id'];?>">
<input type="text" name="score" value="<?php echo $score; ?>">
</p>
</table></td>
</tr>
<hr>
</table><br>
<?php
}
?>
<input type="submit" name="submit" value="Submit Answer" class="btn">
</form>
After hitting the submit button, im only getting s_id, q_id , but the score is still 0 even if I selected the correct answer
My problem here is getting the selected radio button and then comparing it to the answer(where is in the database)

I just did a quick mock up and this worked for me.
$answer = $_POST["'" . $rows['q_question'] . "'"];
if ($correct_answer == $answer)
{
$score++;
}

php shopping cart not displaying items in cart?

I'm trying to implement a php shopping cart on my site. I currently have the products page correctly reading from my database. When the cart is empty, the "There are no items in your cart," text displays, however when the cart has something in it, it displays the headers to this table, but no product information.
<form name="cartform" method="post" action="">

</span>
<div id="formerror"><?php echo $message ?></div>

if(count($_SESSION['cart']))

<th>Quantity</th>
<th>Amount</th>

$max = count($_SESSION['cart']);
for($i = 0; $i < $max; $i++)
{
$product_id = $_SESSION['cart'][$i]['productid'];
$quantity = $_SESSION['cart'][$i]['quantity'];
$product_name = get_product_name($dbc,$product_id);
$product_price = get_price($dbc,$product_id);
if($quantity == 0)
{
continue;
