getting wrong output

andrej13 · January 25, 2011

my output does include $_SESSION['cart'] but no $_SESSION['name']

here is my mail.php

<?php
// Include MySQL class
require_once('inc/mysql.class.php');
// Include database connection
require_once('inc/global.inc.php');

session_start();

if($_POST['sendemail'] == 'Email')
{
  $qry = 'SELECT name FROM products WHERE id=' .$_SESSION['cart'];
  $result = mysql_query($qry);
  $row = mysql_fetch_assoc($result);
  $_SESSION['name'] = $row['name'];
  
  $info =( $_SESSION['cart'] . ' : ' . $_SESSION['name']);
  $headers = 'From: Sender <[email protected]>';
  mail('[email protected]', 'Subject', $info, $headers);
  echo "DEBdsUG".$_POST["cart"]; 
  echo 'Your mail has been sent';
}
else
{
  echo 'Your mail was not sent';
}

?>

cart.php

<?php
// Include MySQL class
require_once('inc/mysql.class.php');
// Include database connection
require_once('inc/global.inc.php');
// Include functions
require_once('inc/functions.inc.php');
// Start the session

session_start();
// Process actions
$cart = $_SESSION['cart'];
$action = $_GET['action'];
switch ($action) {
case 'add':
	if ($cart) {
		$cart .= ','.$_GET['id'];
	} else {
		$cart = $_GET['id'];
	}
	break;
case 'delete':
	if ($cart) {
		$items = explode(',',$cart);
		$newcart = '';
		foreach ($items as $item) {
			if ($_GET['id'] != $item) {
				if ($newcart != '') {
					$newcart .= ','.$item;
				} else {
					$newcart = $item;
				}
			}
		}
		$cart = $newcart;
	}
	break;
case 'update':
if ($cart) {
	$newcart = '';
	foreach ($_POST as $key=>$value) {
		if (stristr($key,'qty')) {
			$id = str_replace('qty','',$key);
			$items = ($newcart != '') ? explode(',',$newcart) : explode(',',$cart);
			$newcart = '';
			foreach ($items as $item) {
				if ($id != $item) {
					if ($newcart != '') {
						$newcart .= ','.$item;
					} else {
						$newcart = $item;
					}
				}
			}
			for ($i=1;$i<=$value;$i++) {
				if ($newcart != '') {
					$newcart .= ','.$id;
				} else {
					$newcart = $id;
				}
			}
		}
	}
}
$cart = $newcart;
break;
}
$_SESSION['cart'] = $cart;

Can you point out where in that code $_SESSION['name'] is assigned a value?

Where do you intend to get the value to assign to $_SESSION['name']?

$_SESSION['cart'] says what the id is of the product i put in the cart, but now I want to have an output with the id of the product, but also the name of the product... 'name' without the brackets is the name of the column in sql

check out how it works http://fhcs.be/cart-demo4
