Help needed finishing shopping cart integration

[edd]

I've got just about everything set up for my site to accepts bitcoins as payment but I'd like to customize my shopping cart a bit more. I'm not a developer, so I need a bit of assistance configuring some variables and sending data to the appropriate places. Right now, I have the MyBitcoin SCI working fine but only using one set price for each generated button. How do I get it to change the amount based on the total in my customers' shopping carts?

I haven't used the SCI myself, but looking at it, it seems that the key is to use the function mbc_encryptformdata()

If you look at the file sci-auto-sample.php in the toolkit, there's an example of how to use it at line 34. You should be able to just change the $amount variable to the price of the shopping cart.

After presenting the form to the user to fill in the amount (or other vars), send the data through the following code:

Code:

$plaintext_querystring="amount=".$amount."&currency=".$currency."&payee_bcaddr=".$payee_bc_addr."&payee_name=".$payee_name."&note=".$note."&success_url=".$success_url."&cancel_url=".$cancel_url."&baggage=".$baggage;

$result=mbc_encryptformdata($plaintext_querystring);

$redirect_url="https://www.mybitcoin.com/sci/paypage.php?t=".$result['SCI Encrypted Form Data Token'];
header("Location: $redirect_url");

You can also get most vars from your own database/cart and fill in the blanks from there.

Sorry, BioMike, I guess I'm a little dense; where does this code go?

When you have the required info you need from the user. That will redirect them to the MyBitcoin page.

It goes in its own page.

Example:

Code: ("shoppingcart.php")

<form action="mybitcoin.php" method="post>
...
input fields that you need in mybitcoin.php (or you get them from a checkout db)
...
<input type="submit" value="Checkout with MyBitcoin">
</form>

Code: ("mybitcoin.php")

Read the fields from shoppingcart.php or checkout database and parse them into $plaintext_querystring

$plaintext_querystring="amount=".$amount."&currency=".$currency."&payee_bcaddr=".$payee_bc_addr."&payee_name=".$payee_name."&note=".$note."&success_url=".$success_url."&cancel_url=".$cancel_url."&baggage=".$baggage;

$result=mbc_encryptformdata($plaintext_querystring);

$redirect_url="https://www.mybitcoin.com/sci/paypage.php?t=".$result['SCI Encrypted Form Data Token'];
header("Location: $redirect_url");
