  1. Hi, I'm currently doing the shopping cart tutorial in studioweb projects. Minor errors appear whenever I add items to the cart and i'm using php 7.2.10. I'll add the screenshot below. I've tried to solve it but the errors won't go away.
  2. Hello, After following along and successfully completing Ben's tutorial of the Online Shopping Cart, I figured I would try and make my own. The first major problem I am having is being able to display my products from my database in my index.php page. The goal is to actually see the images of each product displayed in index.php (like in the tutorial). This would then enable me to add my products to the cart.php page. I've checked the database connection and it does exist. My guess would be that I am using the wrong syntax to display my products in the "fetch_all_products()" method. *** M_PRODUCTS.PHP *** <?php class Products { private $Conn; private $db_table = "toys"; function __construct() { // here we're making sure that the connection from $conn in "init.php" is transferred // into our own private $conn property for usage in this object global $Conn; $this->Conn = $Conn; } // fetches and displays all products from db public function fetch_all_products($id = NULL) { if ($id = NULL) { $data = "<li>"; if ($result = $this->conn->query("SELECT * FROM " . $this->db_table . " ORDER BY name")) { if ($result->num_rows > 0) { while ($row = $result->fetch_array()) { $data .= array( "id" => $row["product_id"], "name" => $row["name"], "price" => $row["price"], "image" => $row["image"] ); } $data .= "</li>"; return $data; } else { return "<h1>Oops... Something went wrong!</h1>"; } } } } } *** INIT.PHP *** <?php // db connection $host = "localhost"; $user = "root"; $pass = "root"; $db = "cart"; $Conn = new mysqli($host, $user, $pass, $db); // error reporting ini_set("display_errors", 1); mysqli_report(MYSQLI_REPORT_ERROR); // constants define("shop_name", "Tremendous Toys"); define("main_path", "localhost/web_apps/shopping_cart/"); define("image_path", "localhost/web_apps/shopping_cart/images/"); // includes include("models/m_shopping_cart.php"); include("models/m_products.php"); // object integrations $Shopping_Cart = new Shopping_Cart(); $Products = new Products(); // session initialisation session_start(); *** INDEX.PHP *** <?php include("init.php") ?> <link rel="stylesheet" href="visual/style.css" type="text/css"> <body> <div id="whitespace"> <h1><?php echo shop_name ?></h1> <?php $Products->fetch_all_products(); ?> </div> </body>
