PHP - Suggestions For Shopping Cart Class
I know there are many open source shopping carts available, but I wanted to write my own to gain a better understanding of the coding practices involved. Below is my almost finished shopping cart class for an e-commerce website I am building. I want to be able to handle all purchasing capability from the Cart class as you can see from what I have below. I was wondering if anyone can see any areas for improvement before I go implementing it into my website. Any help is appreciated and thank you in advance.
Code: [Select] <?php /** * Cart class handles all shopping cart activity. * * This class also handles saving order information for each purchase. * * After each order is complete be sure to call the Product::inventoryCheck() * to notify administrator of low quantities. */ class Cart { public $db; private $_cartName; /** * Creates a new shopping cart if one does not exist already. * Initiates the database connection for future use. */ public function __construct($cartName = 'cart') { $this->_cartName = $cartName; if (!isset($_SESSION[$this->_cartName])) { $_SESSION[$this->_cartName]; } $this->db = Database::getInstance(); } /** * Returns all items in the shopping cart and their information. * I want to be able to return the quantity as well. * I will take this information and use it to display the shopping cart to the customer. */ public function getCartItems() { try { foreach ($_SESSION[$this->_cartName][$id] as $productId => $quantity) { $stmt = $this->db->prepare( "SELECT product_id, product_name, product_thumb, product_price, product_discount FROM product WHERE product_id = ?"); $stmt->setFetchMode(PDO::FETCH_ASSOC); $stmt->execute(array($productId)); return array($stmt->fetchAll(), $quantity); } } catch (Exception $e) { return FALSE; } } /** * Adds an item to the shopping cart. * Also used to change quantities of items already in shopping cart. * @param $id - integer * @param $quantity - integer ($quantity comes from a drop down menu populated by the database) */ public function addItem($id, $quantity) { try { $_SESSION[$this->_cartName][$id] = $quantity; } catch (Exception $e) { return FALSE; } } /** * Deletes an item from the shopping cart. * @param $id - integer */ public function deleteItem($id) { try { unset($_SESSION[$this->_cartName][$id]); } catch (Exception $e) { return FALSE; } } /** * Empties all contents out of the shopping cart. * Call this function when all purchase activity is complete so the user has a new cart to start with. */ public function clearCart() { try { unset($_SESSION[$this->_cartName]); } catch (Exception $e) { return FALSE; } } /** * Saves a purchase after it is successful. * @param $subTotal - integer * @param $tax - integer * @param $discount - integer * @param $total - integer */ public function savePurchase($subTotal, $tax, $discount, $total) { try { $stmt = $this->db->prepare( "INSERT INTO purchase (purchase_customer_id, purchase_timestamp, purchase_ip, purchase_subtotal, purchase_tax, purchase_discount, purchase_total, purchase_status) VALUES (?, ?, ?, ?, ?, ?, ?, ?)"); $stmt->execute(array($_SESSION['customer_id'], NOW(), $_SERVER['REMOTE_ADDR'], $subTotal, $tax, $discount, $total)); return $purchaseId; } catch (Exception $e) { return FALSE; } } /** * Saves each item from a purchase. * Updates product quantities in product table. * @param $purchaseId - integer */ public function saveCartItems($purchaseId) { try { foreach ($_SESSION[$this->_cartName][$id] as $productId => $quantity) { $stmt = $this->db->prepare( "INSERT INTO purchase_item (purchase_item_product_id, purchase_item_purchase_id, purchase_item_quantity) VALUES (?, ?)"); $stmt->execute(array($productId, $purchaseId, $quantity)); $update = $this->db->prepare( "UPDATE product SET product_quantity = product_quantity - $quantity WHERE product_id = ?"); $update->execute(array($productId)); } } catch (Exception $e) { return FALSE; } } /** * Calculates shipping cost and applies it to the shopping cart. */ public function shipping() { // need to find out pricing structure } /** * Applies a coupon discount if coupon parameters are met * Checks for coupon code validity from the coupon table * @param $couponCode - varchar */ public function useCoupon($couponCode, $cartPrice) { try { $stmt = $this->db->prepare( "SELECT coupon_amount, coupon_minimum_price FROM coupon WHERE coupon_code = ? AND coupon_active = 'Yes'"); $stmt->setFetchMode(PDO::FETCH_ASSOC); $stmt->execute(array($couponCode)); $stmt->fetch(); // make sure there is a coupon available that matches customer input if (count($stmt) != 1) { return FALSE; } // chcek if the current cart price (minus taxes and shipping) is greater than coupon minimum price if ($cartPrice < $stmt['coupon_minimum_price']) { return FALSE; } // this will go in the coupon field in the cart view return $stmt['coupon_amount']; } catch (Exception $e) { return FALSE; } } } Similar Tutorialsplease can anyone help direct me in the direction of a book which will help me create a shopping environment. thanks Hey again, Still on the same project but now doing the cart page. I've been bringing my skills up to date a lot doing this project, however, having said that I now can't figure out why my cart is not adding the items to the cart, i've checked the post data and the quantity is set to 1. Would really appreciate someone having a look at it and hopefully can see what i'm missing. you can see what it should look like (well so far lol) at here in my sandbox site. thanks again. (p.s. The parts are all over the place on the page, so thought better put whole page, sorry if shouldn't have done that)

I'm not a programmer but can get buy a little with PHP. My need is a "Shopping Cart" and this is what I would like to see.
I have a MotoCMS web site and would like to but a shopping cart in one page all I need is a "Buy Now" button that can hold the "Item Name" "Price" and "Quantity" and Maybe a selectable option? And a "Cart" for my PayPal that I can put anywhere on the page. If I have to use a database that is OK.
I can put the product pictures and info on the page and then a Buy Now link button would be great.
Does anyone know of a shopping cart that I can use to do this?

Edited by Lon, 28 September 2014 - 09:07 PM. Hi everyone, I am building a shopping cart for a group of friends' website. It is a pay-per-view workout website. Basically, they want to let people find workout videos and pay on a per-day basis (1 day, 3 days, 7 days and depending on the video pricing will be different). I have set them up everything except I am having some difficulty with the shopping cart. I took the basics of the shopping cart script from a tutorial I found online and then modified it. The only problem is that most shopping carts send an action and a product id through the URL and into the session for the shopping cart. Well, I need to also send a price id variable so that the cart will know which price to use. This is because they want to offer pricing on a per-day basis. How would I modify the cart.php page to accomplish this? I have tried, but cannot get the entire thing to work. All help is appreciated. Below is my code: Code: [Select] <?php // if no session is set, initiate one if (!isset($_SESSION)) { session_start(); } // see if the customer is logged in //if (!isset($_SESSION['customer_id'])) //{ //header("location:login.php"); //} // connect to the database require_once('connect.php'); // select the database mysql_select_db($database, $connect); // get the video information if (isset($_GET['video_id'])) { $video_id = $_GET['video_id']; } else { $video_id = 1; } // get the action if (isset($_GET['action'])) { $action = $_GET['action']; } else { $action = "empty"; } // get the video pricing information if (isset($_GET['price_id'])) { $price_id = $_GET['price_id']; } else { $price_id = ""; } // do the following code based on the action switch($action) { // if the action is add then add the product id to the cart session array case "add": if (isset($_SESSION['cart'][$video_id])) { $_SESSION['cart'][$video_id]++; } else { $_SESSION['cart'][$video_id] = 1; } break; // if the action is remove then remove the product id from the cart session array case "remove": if (isset($_SESSION['cart'][$video_id])) { $_SESSION['cart'][$video_id]--; if ($_SESSION['cart'][$video_id]==0) { unset($_SESSION['cart']); } } break; // if the action is empty then remove the cart session array completely case "empty": unset($_SESSION['cart']); break; } ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <meta name="Description" content="Information architecture, Web Design, Web Standards." /> <meta name="Keywords" content="your, keywords" /> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> <link rel="stylesheet" href="layout.css" type="text/css" /> <title>Straight Muscle Videos...Pay-Per-View Alpha Male Muscle Worship Videos</title> </head> <body> <!--wrap starts here--> <div id="wrap"> <?php include('header.php'); ?> <?php include('menu.php'); ?> <!--content-wrap starts here--> <div id="content-wrap" class="two-col"> <?php include('sidebar.php'); ?> <!--main content starts here--> <div id="main"> <h1>Shopping Cart</h1> <br /> <?php if (isset($_SESSION['cart'])) { $total = 0; ?> <table width="95%" border="0" cellspacing="0" cellpadding="5"> <?php foreach($_SESSION['cart'] as $video_id => $x) { $query = mysql_query("SELECT VideoId, VideoTitle, PriceId, PriceVideoId, PriceAmount, PriceTimeId, TimeId, TimeTitle, TimeLength FROM Video, Price, Time WHERE VideoId = $video_id AND PriceId = $price_id AND PriceVideoId = $video_id AND PriceTimeId = TimeId", $connect); $row = mysql_fetch_array($query); $video_name = $row['VideoTitle']; $order_length = $row['TimeTitle']; $video_price = $row['PriceAmount']; $line_cost = $video_price * $x; $total_cost = $total + $line_cost; ?> <tr> <td align="left" valign="middle"><?php echo $video_name; ?></td> <td align="center" valign="middle"><?php echo $order_length; ?></td> <td align="center" valign="middle"><?php echo "$".$line_cost; ?></td> <td align="center" valign="middle"><a href="cart.php?action=remove&video_id=<?php echo $video_id; ?>&price_id=<?php echo $price_id; ?>">Remove</a></td> </tr> <?php } ?> <tr> <td colspan="4" bgcolor="#666666"><span class="shopping_cart">Purchase Total: $<?php echo $total_cost; ?></span></td> </tr> </table> <div align="center"> <form id="shopping_cart" method="post" action="confirm.php"> <input type="submit" name="place_order" id="place_order" value="Place Order" /> </form> </div> <div align="center"> <p><a href="search.php">Continue Shopping</a></p> <p><a href="cart.php?action=empty">Empty Cart</a></p> </div> <?php } else { echo "<br /><br /><div align='center'>There are no items in your cart.</div>"; } ?> <!--main content ends here--> </div> <!--content-wrap ends here--> </div> <?php include('footer.php'); ?> <!--wrap ends here--> </div> </body> </html> Hi All I have my shopping cart working correctly, just a small tweak which i would like to make to it.

Im sure it is only a small tweak which needs to be done.. Any help would be great -Dream Hey all not been on here for a few years, been out of work. i am back and throwing ,myself straight into the deep end. Is it hard to integrate a shopping cart into a website. Any good example snippets of code to look at? I have a little search but someone always seems to know a better one. Why are almost all tutorials these days you have to pay for (times are getting hard ). I have followed a shopping cart tutorial from this website. http://v3.thewatchmakerproject.com/journal/276/ 1. When you refresh the page it adds another item to the cart. 2. I would like to add an image of the products from a folder and the link of the images in the database. Can some one please help. Urgently! Thanks. hi all i have a simple shopping cart up and runniing i just cannot think of how to remove all items within the cart i can do a remove one item easily but how woudl i remove all items inmy cart ? Would i delete the cookie id or ? Need some help on developing the steps below I am working on a website money collection system that consist of stores affiliating to the website and sales their products in the website as independent stores. But I am not sure how to collect the percentage I will deduct per transaction for the stores. I have elaborated two plans but I don't know is those a good ideas in terms of bringing more store in to the website and have them comfortable by the way the website hold business with their stores owners. 1- I was thinking of collecting all the money of transactions into a single paypal account and then try to pay them weekly or in a monthly basis. (I am not sure about this first option because I don't know whether the store owners will be thinking to much into it at the time of making a decision to register and to sell their products in the website. I guess they might think whether the website administrator will delivery the money every week, or if the website administrators are going to steal them etc. So this option I don't know if with some changes can be implemented. 2- The second option was to let each store administer each transaction with their credit/debit machine they have at the store and make the transaction right there and then on a monthly or weekly basis the website administrator charge them for the amount of transaction done during that time period in the website. 3- Third option is create a paypal account for each store and at the moment of the transaction to transfer the money to each store account and have the website paypal account deduct its percentage from the transaction and have the store owner paypal account deduct its part. For healthy business purpose and website grow in terms of acquiring more stores into the website which of those three options would be the best option to choose or if there is another idea even better for business grow and comfortability among stores owner that you guys might have in mind share it. Is selecting an option relevant to the grow of the website or it is? co.ador Can someone give me name of free shopping cart with auctions(offers) like Open Classifieds ? i make a shopping cart,but it dont show the product i have choose. it suppose to show the product i choose at the cart table but its still show the "Your Cart is empty" result..im still new.i follow the instruction from the youtube.sorry for my bad english.

To add items to my shopping cart the user must select a size and then click 'add to basket'. When they do this is adds the item and corresponding size to a string in this format 1s2 where 1 is the id and 2 is the size. Multiple items would look like this 1s2,2s1,1s2 That's all fine. The problem I am now having is getting the code to recognise 1s2 exists twice in the string and putting the $qty to 2 for that item. Here is my current code. Any help on this would be HUGELY appreciated as it's doing my head in! Thanks! Code: [Select] <div id="view_basket"> <ul> <?php $basket = $_SESSION['basket']; if ($basket) { $data = preg_split("#[s,]#", $basket); $data = array_chunk($data, 2); foreach($data as $key => $val) $contents[] = (isset($contents[$data])) ? $contents[$data] + 1 : 1; echo '<form action="basket.php?action=update" method="post">'; echo '<table>'; foreach ($data as $id=>$qty) { $sql = "SELECT * FROM store WHERE id LIKE '$id' AND live LIKE '0'"; $result = mysql_query($sql); while ($rows = mysql_fetch_array($result)) { extract($rows); ?> <li> <div id="view_basket_image"> <img src="<?php echo $rows['indeximage']; ?>" /> </div> <div id="view_basket_title"> <span class="view_basket_brand"><?php echo $rows['brand']; ?> ·</span> <span class="view_basket_description"><?php echo $rows['title']; ?></span> </div> <div id="view_basket_qty"> <input type="text" name="qty<?php echo $id; ?>" value="<?php echo $qty; ?>" size="3" maxlength="3" class="view_basket_qty" /> </div> <div id="view_basket_price"> <span class="view_basket_x">x</span>£<?php echo $rows['price']; ?> <?php /* WORK OUT ITEM WEIGHTS */ $itemweight = $rows['weight'] * $qty; $totalweight += $rows['weight'] * $qty; ?> </div> <div id="view_basket_itemtotal"> <?php $itemtotalprice = $rows['price'] * $qty; $itemtotal = number_format($itemtotalprice, 2, '.', ','); echo '£'; echo $itemtotal; $total += $rows['price'] * $qty; ?> </div> <div class="clear"></div> </li> <?php } } ?> </ul> </div> <?php } ?> Hi guys, I thought of creating a shopping cart in my website.

Above is Viewing the cart which has two buttons. One which clears the cart and the other which will be used to input a new value such as 0 to change the cart and clear that item from the cart- I don't know how to go about doing this so any help is greatly appreciated. Here's the rest of my code.
<!--cart.php-->
<?php
if (!isset($_SESSION)) session_start();
$qstr = $_SERVER['QUERY_STRING'];
parse_str ( $qstr );
?>

This topic has been moved to Miscellaneous. http://www.phpfreaks.com/forums/index.php?topic=349124.0 Hi, Im trying to make a shopping cart. Here is an extract while ($shoppingbasket = mysql_fetch_array($shoppingbasket2, MYSQL_ASSOC)) { echo " <form action='?' method='post'> <td><input type='text' value='$shoppingbasket[qty]' name='qty' /></td> </form> "; } The problem is if there are more than two entries in the cart so I have more than one textbox. I need each textbox assigned to the shopping cart ID to include in the WHERE cause to update the qty otherwise they all get updated the same qty. I hope this makes sences I need a shopping cart that will allow me to restrict access to customers from certain countries. If the customer is from certain other countries they will be directed to contact an office in that country. Any suggestions? Hi guys I'm making a shopping cart where the admin can login and post an item for sale like the example below when posting an new item they will post the details as above. I need a way so when they click the button buy it will link them to paypal with the price specified and then when purchase is successful I can display the details to the buyer. any idea on how I would go around doing this. thanks Hi! I use the following PHP Session Shopping Cart (it's ready to use) Code: [Select] <? session_start(); function showCart() { $cart = $_SESSION['cart']; if ($cart) { $items = explode(',',$cart); $contents = array(); foreach ($items as $item) { $contents[$item] = (isset($contents[$item])) ? $contents[$item] + 1 : 1; } foreach ($contents as $id=>$qty) { $output[] = 'You have '.$qty.' items with ID: '.$id; } } else { $output[] = 'You don\'t have items in your cart'; } return join('',$output); } if(isset($_SESSION['cart'])) { $cart = $_SESSION['cart']; } else { $cart = 0; } if(isset($_GET['action'])) { $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; echo showCart(); echo '<br/>'; echo '<a href="?action=add&id=1">Add to Cart</a>'; ?> Example of usage: === <a href="cart.php?action=add&id=1">Add to Cart</a> // Adding a new product in the cart with ID 1 <a href="cart.php?action=delete&id=1">Delete from Cart</a> // Deleting a new product in the cart with ID 1 <a href="cart.php?action=update&id=1&qty=5">Update Quantity to 5</a> // Updating the quantity of product with ID 1 === Everything is fine, but now I want to add sizes, something like: cart.php?action=add&id=1&size=XXXL. For example, the case "add" can be done like that: Code: [Select] $cart = $_GET['id'].":".$_GET['size'];.. and then the products will be saved like 1:XXXL, but then the updating and deleting will not work .. Please help me, I'm very confused how this can be done For a project I have to create a simple form that allows a user to order a pair of trainers. I understand how to do as the project outlines, but would like to expand on it. Would it be possible for me to substitute a MySQL database for an array that contains an array of products. So that when the user makes an order, the quantity in the array is reduced. The array would look as follows: $prod = array( array( 'id' => '00001', 'name' => 'Pink Converse', 'desc' => 'This is the description of the product.', 'price' => 4500, 'quantity' => 2, 'img' => 'images/prod1.jpg', 'img2' => 'images/00001-2.jpg' ), array( 'id' => '00002', 'name' => 'Tartan Nike Hi-Tops', 'desc' => 'This is the description of the product.', 'price' => 5500, 'quantity' => 2, 'img' => 'images/prod2.jpg', 'img2' => 'images/00002-2.jpg' ), array( 'id' => '00003', 'name' => 'Black Hi-Tops', 'desc' => 'This is the description of the product.', 'price' => 5500, 'quantity' => 2, 'img' => 'images/prod3.jpg', 'img2' => 'images/00003-2.jpg' ), array( 'id' => '00004', 'name' => 'Smart Mens Shoes', 'desc' => 'This is the description of the product.', 'price' => 7000, 'quantity' => 2, 'img' => 'images/prod3.jpg', 'img2' => 'images/00004-2.jpg' ) ); If you know if this is possible or not, you would be a great help, any ideas would also be welcome.
