[plugin] [ORPHAN] joe_gcart - wfCart with Google Checkout
I’ve posted a little proof of concept wfCart based shopping cart with Google Checkout support.
This plugin is designed to be a simple starting point for the development of a session based textpattern shopping cart with support for flat rate shipping and Google Checkout. joe_gcart supports simple items with no variations (color, size, etc…) and a single flat rate shipping cost per item.

Very cool. You’ve done an excellent job on this one.
I’d like to extend this to do options (color & size).

Nice start Joe. (I love Snoqualmie, beautiful country). One thing I think you’re going to need to add into the equation is an image. Most store products generally offer up a glimpse so people know what their getting.
I’m about to launch a new client site where I did a small shopping cart with PayPal; not fully integrated, but using their standard process and creating a Txp article/form situation like yours that displays the items as a nice menu in Textpattern, including image. I used the <code><txp:article_image /></code> field to add the image ID for each product. Works nice. Each product article is floated left, much like a photo gallery grid, giving that typical store products display.
As soon as the site launches, I’ll write up a tute and maybe that can help shed light on further plugin aim.
P.S. By the way, you can add this plugin to the plugin archive too and supply a PayPal button for potential donations. You might also look at the plugin requests for a similar plugin for PayPal, since you’re motoring down that road (though I think the request there is for a completely integrated solution where the whole transaction takes place in the Txp site). ;)

Oh! This is great step to manage an e-commerce site with TXP!
The thing is that sometimes you need to redirect your clients to your site after the payment to give them access to a file, program, document, etc.
Eg.: if you have a music store and would like to sell songs or albums in MP3 or Ogg format.
Any idea about how to do it using Textpattern?
As I know the big trouble is that files uploaded through Textpattern are not really safe to do this …
Thx in advance!

With PayPal anyway (don’t know about Google) this is easily done. Part of the code in my recent project I was referring to above adds a redirecting URL that brings a user back to the site after the transaction is done, wherever you want. This is something PayPal provides, you only need to add it to your form code.

You can use the <code><continue-shopping-url></code> field to direct users back to a download page after processing their payment with Google Checkout. Currently joe_gcart does not have an option for <code><continue-shopping-url></code>, but I can work on adding it.

Re: [plugin] [ORPHAN] joe_gcart - wfCart with Google Checkout
Hi Joe,
I am trying to use wfCart with TXP to build an e-commerce website and I am getting grief with session initialization. This is my header code:
<pre><txp:php>
include “bck_cart.php”;
session_start();
global $cart; // so that $cart is accessible in other forms etc.
$cart = $_SESSION[‘bck_cart’];
if(!is_object($cart)) $cart = new bckCart();
</txp:php></pre>
The error that I am getting is
<pre>tag_error <txp:php> -> Notice: Undefined index: bck_cart on line 8
textpattern/publish/taghandlers.php:1865 eval()
textpattern/publish.php:904 php()
processTags()
textpattern/publish.php:878 preg_replace_callback()
textpattern/publish.php:440 parse()
index.php:28 textpattern()</pre>
If I use <pre>$cart =& $_SESSION[‘bck_cart’];</pre> (because that’s how the original code is), I am getting non-object errors e.g.
<pre>tag_error <txp:php> -> Notice: Trying to get property of non-object on line 23
textpattern/publish/taghandlers.php:1865 eval()
textpattern/publish.php:904 php()
processTags()
textpattern/publish.php:878 preg_replace_callback()
textpattern/publish.php:440 parse()
index.php:28 textpattern()</pre>
Any help will be appreciated since this is doing my head in.
I am including the above code through a doc_head form.

<code>include(‘bck_cart.php’);</code> ← like that
and assign <code>$_SESSION[‘bck_cart’]</code> to <code>$cart</code> with just an equals sign (no ampersand).
Should work…..i think.

Nope, still doesn’t work.
It didn’t seem right with an ampersand in the first place, but that’s the code on Webforce website: http://www.webforce.co.nz/cart/php-cart.php.
There is something wrong with sessions… Yet when I download the original code from Webforce, it seems to work (even with that ampersand…).
Help!

Re: [plugin] [ORPHAN] joe_gcart - wfCart with Google Checkout
I believe the problem may be with your global declaration of $cart.
What happens if you comment out <code>global $cart;</code>?
<code>=&</code> assignment and references: return references

Cheers Joe, you were spot-on!
I used <code>global</code> to have <code>$cart</code> available in other parts of the website (header for cart overview, cart page for data manipulating etc.). I use <code><txp:php></code> and, as you might now, TXP doesn’t pass variables between <code><txp:php></code> chunks. Even if statements don’t work across multiple <code><txp:php></code>. Re-assigning <code>$cart</code> to <code>$_SESSION</code> did the trick! I was also able to use <code>$cart</code> by reference and thus <code>cart()</code> is called correctly.
Unfortunately Checkout isn’t available to the UK market, but that would have been my first option if I was working on a US e-commerce website. Your plugin would have been invaluable in that case! Great job!
Everything seems to be working now. If I get into any more trouble, I will let you know. You really are a great community ; ).
One more time, cheers Joe!!!
