I have a shopping cart in which the orders are being shown, i am using session to store the cart contents. Now what i want to do is to insert the cart contents into a database upon the press checkout button. But everytime any user checks out only the word "Array" is being inserted into the DB. What i have tried -
$sqlimp = implode(",", $_SESSION["cart"] );
and the n print_r the $sqlimp and it shows Array,Array,ArayArray,Array,Array (if there is 2 items). Below is my code - index.php
<?php
session_start();
// print_r($_SESSION["user"]);
if(! isset($_SESSION["user"])){
header("Location: index.php");
}
require("connection.php");
if(isset($_GET['page'])){
$pages=array("products", "cart");
if(in_array($_GET['page'], $pages)) {
$_page=$_GET['page'];
}else{
$_page="products";
}
}else{
$_page="products";
}
?>
