PHP - Help: Google Checkout Integration

I could use some suggestion on how to model the Checkout Process for my e-commerce site.

As I see it, when a person "checks out" there are 5 steps...

1.) Create an Account/Log-In
2.) Enter Addresses
3.) Choose Shipping Options
4.) Enter Payment Details
5.) Review & Place Order

I'm trying to avoid having gigantic "God classes" and struggling to figure out how to abstract things in good OOP terms.

My Head First: Design Patterns book talked about the "State Pattern" and I'm wondering if that might be a good approach?   

Maybe each of the 5 steps above could be a "state" in the Checkout Process?

What do you think?

Hi, I have set up a simple shopping cart with a coupon code function.

I am having an issue with the Update basket and Checkout buttons, when you click update basket it loads the /checkout/ page but then redirects back to the /cart/ after a couple of seconds when it should just load a new page saying 'Shopping basket successfully updated' - also, when you click the proceed to checkout button it does the same, loads the /checkout/ page (which is correct) but then redirects back to /cart/.

Here is the php code I have setup:

// View Shopping Basket

if (!isset($_GET['action']) || $_GET['action'] == 'products') {
// Check if the shopping basket is empty

if ($cart->get_num_products(session_id()) <= 0) {
output('Your shopping basket contains no products!');
} else {
if (!isset($_POST['submit'])) {
$tpl->set('body', $body->fetch('index.tpl.php'));
} else {
$cart->update_contents(session_id());
output('Shopping basket successfully updated!');
redirect('/cart/', 2);
}
}
}

// Add Product to Cart

if (isset($_GET['action']) && $_GET['action'] == 'add_product') {
$product_id = isset($_GET['product_id']) && is_numeric($_GET['product_id']) ? (int) $_GET['product_id'] : 0;
$cart->add_product(session_id(), $product_id, 1);

output('Product successfully added! Please wait while we redirect you to your shopping basket.');
redirect('/cart/', 2);
}

if (isset($_SESSION['coupon_code'])){
unset($_SESSION['coupon_code']);
}

if (isset($_POST['go']) && $_POST['go'] != ''){
$_SESSION['coupon_code'] = $_POST['coupon_code']; 
header("location:/checkout/");
}

Here is the HTML for the form:

Code: [Select]
<h1>My Basket</h1>
<form method="post" action="/cart/">
<input type="hidden" name="submit" value="Update" />
    <input type="hidden" name="go" value="true" />
<table class="tableGrid">

<th width="60%"><strong>Product Name:</strong></th>
<th width="10%"><strong>Price:</strong></th>
<th width="10%"><strong>Qty:</strong></th>
<th width="10%"><strong>Total:</strong></th>
</tr>
<?php foreach ($GLOBALS['cart']->get_contents(session_id()) as $product) { ?>
<tr>
<td align="center" width="10%"><input type="checkbox" name="delete<?php echo $product['cart_id']; ?>" value="yes" /></td>
<td width="60%"><a href="<?php echo get_url('/products/', $product['category_id'], $product['product_id'], $product['product_name']); ?>"><?php echo $product['product_name']; ?></a> <span class="important">* <?php echo $product['stock'] >= $product['quantity'] ? 'Available' : 'Not Enough In Stock'; ?></span></td>
<td width="10%" align="center"><?php echo get_price($product['price']); ?></td>
<td width="10%" align="center"><input type="text" name="quantity<?php echo $product['cart_id']; ?>" value="<?php echo $product['quantity']; ?>" maxlength="10" style="width: 30px;" /></td>
<td width="10%" align="center"><?php echo get_price($product['price'] * $product['quantity']); ?></td>
</tr>
<?php } ?>
</table><br />
        <div class="main_box" style="height: 26px;">
        <div style="float: right;">Subtotal: <strong><?php echo get_price($GLOBALS['cart']->get_cart_total(session_id())); ?></strong></div>
<div style="float: left;">
<label><strong>If you have a promotion voucher code please enter it he </strong></label>
<input type="text" name="coupon_code" id="coupon_code" value="" />
</div>
        </div><br />
<div align="center"><input type="image" src="<?php echo '/' . $config['image_path']; ?>button_cart_update.gif" border="0" alt="Update Shopping Basket" /> <a href="/shop-11/"><img src="<?php echo '/' . $config['image_path']; ?>button_continue.gif" border="0" alt="Continue Shopping" /></a> <input type="image" name="checkout" src="<?php echo '/' . $config['image_path']; ?>button_checkout.gif" border="0" alt="Proceed to Checkout" /></div>
</form>
If anybody can spot whats wrong I would really appreciate it. - It is probably something so simple but I am finding ti quite frustrating.

Thanks,

Hi all,

I am looking to integrate Paypal Express checkout on my site and have been working with the API today.

I have got the code working in a static state with predefined payment amounts but I am having trouble making this dynamic.

When you first submit a request to set up an express checkout you send the payment amount along with it. The paypal server then makes the checkout and the user is redirected to the paypal site to login and authenticate. From here they click to be redirected back to my site where I have a pay button which when clicked submits the final request to confirm the payment.

I am sure there must be a simple solution to this because so many people use paypal already but when you submit the final confirmation request, you have to send the payment amount again, but because the page redirects onto the paypal page inbetween, I can't use a session variable to store the amount. How have other people overcome this?

Thanks

Hey guys!

I need your help with some issues.
Firstly, I have an own website with a database filled with products, and also a template page(template.php) for each product. Problem is that I don't know how to generate each product from the database in the template.php file using their id from the database. How can I do this?

Second problem, I got an own checkout and I don't know how to redirect the customer to a "thank you for buying" page after clicking "Finish Order". It sends the customer to a white page where it says: "Thanks for buying!".

Third and last thing, do you guys know where can I find a php checkout template to follow?

Thanks in advance for your answers!
Cheers!

Hi,

I'm building a webshop and im stuck at the checkout.

I'm using this Shopping Cart class http://www.webforcecart.com/manual.html
The cart is stored as an object in $_SESSION[cart].

This method
Code: [Select]
print_r($cart->get_contents());would get this as output:
Array ( => Array ( [id] => 7 [qty] => 1 [price] => 11.00 [info] => Test [subtotal] => 11 ) [1] => Array ( [id] => 6 [qty] => 2 [price] => 19.00 [info] => White 0 [subtotal] => 38 ) )


In the table Order I would like to store
order-id
customer-id
total products
total quantity
total price
date

In the table Orderrow I would like to sto
order-id,
product-id,
product-name,
quantity,
price,
subtotal

I know i can get the order-id with the function mysql_insert_id() but how can i store each product in the array with their info in the table Orderrow?
Or is there a better way to do this? please advice me, thank you.

Dear forum,
my name is Dominic from germany.

I`m always trying hard, but after 5 hours I really need some help in php coding.

My problem deals with my checkout page for woocommerce.

At the moment, my legal terms are above the total-order-table where u can find the booked product, order-subtotal, order-total and tex-total.

But I need to display the legal terms under my total-order table. I need the terms directly above the "Buy now" button.

Do you guys know which file to modify ? I tried everything. Nothing worked for me.

You will find a picture in this post. There you can see my problem. 

Would be pretty nice if you can give me some information.

Kind regards,
Dominic Lindner

I currently have a project undergoing, however i need help integrating two scripts:

Login script & Comment Script

The checking if logged in part is this - Code: [Select]
if(!isset($_SESSION['SESS_MEMBER_ID']) || (trim($_SESSION['SESS_MEMBER_ID']) == '')) {
header("location: access-denied.php");
exit();
}
and i want it so that i can check if the user is logged in the comment script will use there first name from my mysql table of members.

The field name in the table for first name is 'firstname' and my comment section script looks like this

Code: [Select]
echo "<div class=\"commentbody\" id=\"$commentrow[0]\">\n
<p class=\"postedby\">Posted by ";
if($commentrow[3]){
        echo "<a href=\"$commentrow[3]\">$commentrow[2]</a> ";
} else {
echo "$commentrow[2] ";
}
echo "</p> \n
        <p>$commentbb</p>\n\n</div>";
}
echo "</div>";
}
Please someone help me, its driving me crazy.

Any more info needed just ask many thanks in advance!!

Okay, I run a website; I wrote it from scratch, it's own database. With this website, I also run a news section (Run by wordpress), a wiki (Run by MediaWiki), A chat system (X7Chat), and a Live Help system (Mibew Messenger). I am looking to integrate all four of these systems to run off the same login as my main website. I would like it so that when the user logs in to the main site, it automatically logs in and sets the cookies for the other 4 systems. I also want it so when a user registers, it automatically registers them on the other 4 systems.

I have achieved this with the chat system. I duplicated the Cookies and I have it so that if a user logs in to the main site, it sets the cookies for the chat, and when a user registers, or changes their password or email, it updates it on the chat table.

But, I am finding it quite more difficult for the Wiki, Wordpress, and the Live Help system. The cookies were easy to duplicate for the chat system, and inserting the rows was fairly simple for the chat system, but it is quite a bit more complicated with the other systems. I am hoping someone here has done this before and could help me out on this one, because I am clueless.

Thanks in advance for all that help.

I have set up u chat page on my site and would like to know how to make it use the logged in members user name from my database rather than assigning them a guest name, i think i have found the code that needs editing but i have no idea what needs to be done.

I think the editing needs to be done in this code somewhere but i could be wrong, Please help.

Code: [Select]
<?php

require_once dirname(__FILE__)."/src/phpfreechat.class.php";
$params = array();
$params["title"] = "Quick chat";
$params["nick"] = "guest".rand(1,1000);  // setup the intitial nickname
$params['firstisadmin'] = true;
//$params["isadmin"] = true; // makes everybody admin: do not use it on production servers ;)
$params["serverid"] = md5(__FILE__); // calculate a unique id for this chat
$params["debug"] = false;
$chat = new phpFreeChat( $params );

Hey All, 

I am using a Curl script to call item details from an API and then updating mysql with the results. But the API is limited to 100 requests per 60 seconds. So I am currently just using:

$page = $_GET["page"];
$next_page = ++$page;
echo "<meta http-equiv='refresh' content='60;url=?page=".$next_page."'>";

This runs until the results from the API runs out, then resets the page number to 1 and loops through again. 

My question is, will this would the same with a CRON job?

 

 

Okay so i have a flash game website. I want it so that i can list all the games in a category onto one page.
So, php selects the items with the category with mysql(for example 'a for arcade' http://url.com/select.php?cat=a) and then lists every game's name and a link to the url (by grabbing the id of the game and providing a link (http://url.com/play.php?id=1)


This is the code i have so far..

<?php
$con = mysqli_connect('localhost', 'root', 'root', 'games')or die(mysqli_error($con));

if(isset($_GET['cat'])){
     $query_var = $_GET['type']; // force it to be an integer

 $query=" SELECT * FROM games WHERE category = '$query_var'";

     $result = mysqli_query($con, $query)or die(mysqli_error($con));
     }
}

?>
