PHP - Cookie Size Problem With Shopping Cart
Similar TutorialsHi, I am using a $_SESSION for my shopping cart but cannot figure out how to total my quantity. The format I am using is: $_SESSION['cart']['itemid']['qty'] I realise that i could write a for loop to start at item id 0 and end at 1000 each time totalling the qty field but there must be a better, more efficient way, Does anybody have any advice? Mark hi my first language is german my english is not good so kindly bear it i have uploaded my files on free server /hosting site when i run it it shows me my products now the problem i m facing is when i click on add to cart it generates me this this error or warning at the all above page it generates this error Warning: Cannot modify header information - headers already sent by (output started at /www/clanteam.com/a/z/e/azeempro/htdocs/cart/include/config.php:1) in /www/clanteam.com/a/z/e/azeempro/htdocs/cart/public/index.php on line 33 below it it add products in cart array Shopping Cart Array ( [2] => 1 ) 1 Items $90.00 checkout below that it gives this warning Warning: include() [function.include]: Unable to access /www/clanteam.com/a/z/e/azeempro/htdocs/cart/public/views/shop/add_to_cart.php in /www/clanteam.com/a/z/e/azeempro/htdocs/cart/public/views/layouts/shop.php on line 24 Warning: include(/www/clanteam.com/a/z/e/azeempro/htdocs/cart/public/views/shop/add_to_cart.php) [function.include]: failed to open stream: No such file or directory in /www/clanteam.com/a/z/e/azeempro/htdocs/cart/public/views/layouts/shop.php on line 24 Warning: include() [function.include]: Failed opening '/www/clanteam.com/a/z/e/azeempro/htdocs/cart/public/views/shop/add_to_cart.php' for inclusion (include_path='.:/usr/lib/php') in /www/clanteam.com/a/z/e/azeempro/htdocs/cart/public/views/layouts/shop.php on line 24 kindly help me i think there is path problem kindly solve this out please i will be thankful regards this is my index page Code: [Select] <?php include('db_fns.php'); include("cart_functions.php"); if(!isset($_SESSION['cart'])) { //session_start(); //session_start($_SESSION['cart']); $_SESSION['cart']=array(); $_SESSION['total_items']=0; $_SESSION['total_price']=0.00; } $view=empty($_GET['view'])?'index':$_GET['view']; $controller='shop'; switch ($view){ case "index": $products = find_product(); break; case "add_to_cart": $id=$_GET['id']; $add_item=add_to_cart($id); $_SESSION['total_items']=total_items($_SESSION['cart']); $_SESSION['total_price']=total_price($_SESSION['cart']); header('Location: index.php'); break; case "update_cart": update_cart(); $_SESSION['total_items']=total_items($_SESSION['cart']); $_SESSION['total_price']=total_price($_SESSION['cart']); header('Location:index.php?view=checkout'); break; case "checkout": $shipping=0.00; if($_SESSION['total_price']<=100.00 || $_SESSION['total_price']<=200.00){ $shipping=$shipping + 30.00; }elseif($_SESSION['total_price']<=300.00 || $_SESSION['total_price']<=500.00){ $shipping=$shipping + 45.00; }elseif($_SESSION['total_price']<=600.00 || $_SESSION['total_price']<=1000.00){ $shipping=$shipping+ 70.00; }elseif($_SESSION['total_price']>1000.00){ $shipping=$shipping+ 100.00; }else{ $shipping=10.00; } break; } include ('/www/clanteam.com/a/z/e/azeempro/htdocs/cart/public/views/layouts/'.$controller.'.php'); ?>shop.php is Code: [Select] <?php ?> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en"> <head> <title> Shopping Cart</title> <link href="stylesheets/cool_style.css" media="screen" rel="Stylesheet" type="text/css" /> </head> <body> <h1> products</h1> <div class="cart"> <p><b> Shopping Cart</b></p> <p><?php print_r($_SESSION['cart']);?></p> <p><?php echo $_SESSION['total_items'];?> Items </p> <p>$<?php echo number_format($_SESSION['total_price'],2);?></p> <p><a href="index.php?view=checkout">checkout</a></p> </div> <hr/> <?php include('/www/clanteam.com/a/z/e/azeempro/htdocs/cart/public/views/'.$controller.'/'.$view.'.php');?> </body> </html> I followed tutorial from youtube Code: [Select] http://www.youtube.com/watch?v=5b3TcoeY7Bsand made shopping cart.

Anyone willing to lend a helping hand? 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)

Hi All I have my shopping cart working correctly, just a small tweak which i would like to make to it. Here is the code i currently use... Code: [Select] echo '<p>' . $fldname . ' <a href="cart.php?action=add&id=' . $row['idinfo'] . '">Add to report</a></p>'; But i want it so that when i click 'Add to report' is does not take me to cart.php, but it still adds the item into the shopping cart. kind of just refeshs the current page? 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 ). 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 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 ? 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.

<?
session_start();
require("connection.php");

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 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> 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. 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 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 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 Hello. I could use some advice on the best way to handle my shopping cart. My website will sell subscriptions along with more traditional items like books, t-shirts, etc. For subscriptions, I have these business rules... 1.) Only non-members can purchase a "trial subscription". 2.) Once you are a "member", then no more trials for you! 3.) You can purchase multiple subscriptions (e.g. into the future), BUT I only allow you to purchase ONE subscription at a time. (My system would allow multiple purchases at once, but I don't ant people accidentally signing up for 2 years and then i have to clean things up. Also, I want the transition from a "trial" to a "full paid" subscription to be clear.) 4.) if I ever offer multiple "trial" offers, then you only get to take advantage of one, and then after that it's on to full paid subscriptions for you - although I will run "promos".
Here is the problem... Nothing stops a non-member (or a member) from adding a "paid" and a "trial" subscription into their shopping cart. Or multiple "trial" subscriptions. Or multiple "paid" subscriptions. (Maybe someone adds a paid subscription on Friday, then the weekend comes, and on Monday they notice the trial subscription offer and add that forgetting about the paid subscription.) Or maybe someone is trying to "game" things, and adds 3 "trial" subscriptions and tries to check out?!
How should my website (gracefully) handle these scenarios?
1.) Am I aggressive up front, and prevent people from adding a 2nd subscription to their shopping cart as they shop? 2.) Or do I allow them to go wild while shopping, but then address the issue at checkout? 3.) Should my code be doing the work, or is the onus on the user to go in and clean up their shopping cart? 4.) If I address this issue at checkout, then do I need to add extra functionality to adjust their shopping cart from the checkout page on-the-fly? Or do I send them back to their actual shopping cart page and make them clean things up there? 5.) What do I do if someone has already added other items to their cart previously (e.g. T-shirts). Do I handle the "Get this offer" separately hoping to get them signed up ASAP, and then leave the T-shirts in their cart to purchase later? Or do I handle everything at once? (If they just have a "trial" subscription and a T-shirt, no worries. But if they have a "paid" subscription and then add a "trial" subscription and are looking for a quick checkout, then the scenarios/concerns above come into play...)
The stuff I was asking about last night is what got me to thinking about all of this. The flow was supposed to go... User sees "get one month for $1" on the home page, clicks the button, gets a trail-offer details paid, clicks "Get this offer", and wah-lah, they are on the checkout page! But if they already have things in their cart or maybe click the offer button 10 times, then things get messier. My concern is that converting a user to a paid member is the #1 goal, and I don't want other things to get in the way, whether that is a complicated checkout or things getting distracted purchasing other things like T-shirts! At the same time, if you want to buy multiple things, all the better as long as you follow my business rules.
So what's the best way to not be a pain to shoppers, but to maintain the rules I mention above? Edited September 9, 2020 by requinix edited at author's request Hello. I'm trying to figure out the most logical way to update my shopping cart (table). When my checkout.php script loads, I need to run some checks on all cart items and take appropriate action. For example, a "Trial Offer" is only available to non-Members, so if a Member somehow has a "Trial Offer" in his/her shopping cart then I'd like my checkout.php script to remove that automatically from the Member's cart. So when checkout.php loads, one of the first things I do is to read the user's shopping cart items from the database. But what is the most logical way to update the shopping cart table? Do I load the shopping cart records into an array, then iterate through them, remove any non-applicable "Trial Offers" and then write things back to the shopping cart table? (If so, then how do I merge things? This is what is confusing me...) Or do I somehow iterate through the shopping cart records for the user and update each record at a time and avoid loading things into memory like using an array? Again, this seems like a simple enough task, but I'm not sure the smartest way to do things?!
