无法将产品添加到购物车

Question

When I click on add to cart, It's not working although the button change from 'Add to cart' to 'Adding' meaning the jquery is working.

I am creating an e-commerce with add to cart functionality but when I click on add to cart the products name is not added to the cart. Although the button changes, meaning the json is working but the selection is not working.

add produce in cart (manage_cart.php)

    if(isset($_POST["product_code"])) {
        foreach($_POST as $key => $value){
            $product[$key] = filter_var($value, FILTER_SANITIZE_STRING);
        }   
        $statement = $this->conn->prepare("SELECT product_name, product_price FROM products WHERE product_code=? LIMIT 1");
        $statement->bind_param('s', $product['product_code']);
        $statement->execute();
        $statement->bind_result($product_name, $product_price);
        while($statement->fetchAll()){ 
            $product["product_name"] = $product_name;
            $product["product_price"] = $product_price;     
            if(isset($_SESSION["produce"])){ 
                if(isset($_SESSION["produce"][$product['product_code']])) {             
                    $_SESSION["produce"][$product['product_code']]["product_qty"] = $_SESSION["produce"][$product['product_code']]["product_qty"] + $_POST["product_qty"];              
                } else {
                    $_SESSION["produce"][$product['product_code']] = $product;
                }           
            } else {
                $_SESSION["produce"][$product['product_code']] = $product;
            }   
        }   
        $total_product = count($_SESSION["produce"]);
        die(json_encode(array('produce'=>$total_product)));
    }

                $("#cart-container").html(data.products);
                button_content.html('Add to Cart');             
            })
            e.preventDefault();
        }); 

when I click on the add to cart button, I want the product to be added to the cart. Thanks

Answer 1

One of reason behind this is that you define die(json_encode(array('produce'=>$total_product))); in manage_cart.php

It means result is stored in produce and when you get result in jquery using data.products .

Thats why its not getting result.

So please replace name in one place either in manage_cart.php or jQuery code
