How to submit all cart items using a form and insert into a database table

I have some problems while placing an order on my php cart website. I have added cart items successfully, but when I place an order, all cart items should insert my order table into the base. I am using a form to post all values ​​from a cart and insert into a database. The last updated cart item only inserted my database. The rest of the items were not inserted into my database. Someone please help me. Thanks in advance.

My code

foreach ($_SESSION["cart_array"] as $each_item) {

    $item_id = $each_item['item_id'];
    $sql = mysql_query("SELECT * from products WHERE pid='$item_id' LIMIT 1");
    while ($row = mysql_fetch_array($sql)) {
        $product_name = $row["pname"];
        $price = $row["price"];
        $details = $row["description"];
        $image = '<img style="border:#666 1px solid;" src = "admin123/products/' . $item_id . '.jpg" alt="' . $product_name. '" width="50" height="50" border="1" />';
    }
    $pricetotal = $price * $each_item['quantity'];
    $cartTotal = $pricetotal + $cartTotal;

    $cartOutput .='  <form action="cart.php" method="post">
    <div class="col-lg-2 col-md-2 col-sm-2 pm-cart-info-column">'.$image.'
                        </div>
                        <div class="col-lg-2 col-md-2 col-sm-2 pm-cart-info-column text">
                            <a href="store.php?pid='.$item_id.'">'.$product_name.'</a>
                        </div>

                        <div class="col-lg-2 col-md-2 col-sm-2 pm-cart-info-column text">
                            <p>Price: '.$price.'&nbsp;€&nbsp;</p>
                        </div>

                        <div class="col-lg-2 col-md-2 col-sm-2 pm-cart-info-column quantity">
                            <div class="quantity buttons_added pm-checkout-quantity">
                                  <input type="number" size="4" class="input-text qty cart text" title="Qty" value="' . $each_item['quantity'] . '" name="quantity" min="1" step="1" >                    
                            </div><!-- quantity buttons end -->
                        </div>

                        <div class="col-lg-2 col-md-2 col-sm-2 pm-cart-info-column text">
                            <p>Sub-Total: '.$pricetotal.'&nbsp;€&nbsp;</p>
                        </div>

                        <div class="col-lg-2 col-md-2 col-sm-2 pm-cart-info-column">
                            <a href="cart.php?index_to_remove='.$i.'" class="pm-rounded-btn pm-primary pm-cart-remove">Remove</a>
                        </div>
                        <input type="hidden" name="order-pname" value="'.$product_name.'">
<input type="hidden" name="order-price" value=" '.$price.'">
<input type="hidden" name="order-qty" value="' . $each_item['quantity'] . '">
<input type="hidden" name="order-total" value="'.$pricetotal.'">
<input type="hidden" name="item-id" value="' . $item_id . '">

                         ';
                         $i++;
                         }
