Trying to delete a row from my SQL table in my shopping cart page,but my code deletes all the rows from the table on clicking a button.Even when I update quantity of the one product the quantity of all the products are changing.The answer might be the same for these two issues.Could you please review my code and tell me where I've done wrong.
Thankyou in advance

This is (productpage.php) from where I'm storing the values to the cart table.Probably not so important to this issue. If yes
<?php
ob_start();
include ('header.php');
require('includes/connect.php');
require('includes/product.php');
$product = new Product;
if(isset ($_GET['id'])) {
$id = $_GET['id'];
$data = $product -> fetch_data($id);
if(isset($_POST['add'])){
if (isset($_SESSION['logged_in'])) {
$query = $pdo->prepare("SELECT product_id FROM cart_items WHERE product_id= ?");
$query -> bindValue(1, $id);
$query ->execute();
$num=$query->rowCount();
if($num == 0){
if(isset($_POST['qty'])){
$qty=$_POST['qty'];
}
$query = $pdo -> prepare("INSERT INTO cart_items(product_id , user_id, quantity,price,product_name) VALUES (?,?,?,?,?)");
$query -> bindValue(1, $id);
$query -> bindValue(2, $_SESSION['user_id']);
$query -> bindValue(3, $qty);
$query -> bindValue(4, $data['new_price']);
$query -> bindValue(5, $data['product_name']);
$query ->execute();
header('location:cart.php');

else{
echo " The product is already in your Cart";
}

This is the product.php
<?php
