![Proof that $k^4 + k^2 + 1$ is a composite number for all $k > 1$ [duplicate]](https://lh3.googleusercontent.com/-vowi35hWT8k/AAAAAAAAAAI/AAAAAAAAAAA/AKxrwcYSCxaI-F9EhYSiYMi0CA95y-JOFw/s72-c-mo/photo.jpg?sz=32)
Updating values of array - PHP
-1
I have a shopping cart. I add items to them and this is the code of inserting an item to the cart.
My problem is that for some reason, when I have more than one element in my cart, If I add more quantity to one item, the quantity will be updated on the item with index + 1.
For example.
Empty cart now.
Add item A, 1 quantity.
Cart = item A , 1 quantity
Add item B, 1 quantity.
Cart = item A , 1 quantity, item B 1 quantity.
But now comes the problem.
If i add item A 1 quantity again. My cart will be
Cart = item A, 1 quantity, item B 2 quantity....
Can someone help me ?
<?php
session_start();
require_once("dbcontroller.php");
$db_handle = new DBController();
if(!empty($_POST["quantity"])) {
$productByCode = $db_handle->runQuery("SELECT * FROM products WHERE id='" . $_GET["id"] . "'");
$itemArray = array($productByCode[0]["id"]=>array('name'=>$productByCode[0]["name"], 'id'=>$productByCode[0]["id"], 'quantity'=>$_POST["quantity"], 'price'=>$productByCode[0]["price"], 'image'=>$productByCode[0]["image"]));
if(!empty($_SESSION["cart_item"])) {
if(in_array($productByCode[0]["id"],array_keys($_SESSION["cart_item"]))) {
foreach($_SESSION["cart_item"] as $k => $v) {
if($productByCode[0]["id"] == $k) {
if(empty($_SESSION["cart_item"][$k]["quantity"])) {
$_SESSION["cart_item"][$k]["quantity"] = 0;
}
$_SESSION["cart_item"][$k]["quantity"] += $_POST["quantity"];
}
}
} else {
$_SESSION["cart_item"] = array_merge($_SESSION["cart_item"],$itemArray);
}
} else {
$_SESSION["cart_item"] = $itemArray;
}
}
?>
And this is the code I use to output HTML.
$template->setCurrentBlock("SHOPPINGCART");
foreach ($_SESSION["cart_item"] as $item){
$item_price = $item["quantity"]*$item["price"];
$template->setVariable("item_image", $item['image']);
$template->setVariable("item_name", $item['name']);
$template->setVariable("item_id", $item['id']);
$template->setVariable("item_quantity", $item['quantity']);
$template->setVariable("item_price", $item['price']);
$template->parseCurrentBlock();

The whole handling of the cart array data is rather bogus and convoluted. You don’t have to test whether$_SESSION["cart_item"]is empty. All those in_array calls and looping over all the data to find a specific item, also unnecessary.$_SESSION["cart_item"][some-product-id]is either set or not.

I don't quite understand your code but to be sure you are getting the product details and putting it to the cart session correct me if I'm wrong.
if(isset($_POST['quantity'])){
$qty = $_POST['quantity'];
$pid = $_POST['id'];
//retrieve product as object
$result = json_encode($db_handle->runQuery("SELECT * FROM products WHERE id='" . $_GET["id"] . "'"));
//decode the object
$item = json_decode($result);
//assign product id as key and the item collection as value
$_SESSION['cart_item'][$pid] = $item;
//then you have to assign the quantity
$_SESSION['cart_item'][$pid]->quantity = $qty;
//You can check now that quantity is updating accordingly and you have access to all props of your product
var_dump($_SESSION['cart_item']);
echo $_SESSION['cart_item'][$pid]->quantity;
}
I hope this helps!
