Essentially what I want to do is take advantage of paypals shopping cart variables. Currently open cart only sends a lump sum to paypal, but paypal has features that enable a page to send items to the paypal cart. These features would allow a user to have a better confirmation of their order so that they know exactly what they are paying for. These variables can easily be sent to paypal through hidden inputs. Go to https://www.paypal.com/IntegrationCente ... pload.html to see how all this works. I'll give an example below.
This would be an example cart sending multiple items to paypal's checkout:
Code: Select all
<form action="https://www.paypal.com/cgi-bin/webscr" method="post">
<input type="hidden" name="cmd" value="_cart">//<----------------------------------------important change
<input type="hidden" name="upload" value="1">//<------------------------------------------important change
<input type="hidden" name="business" value="seller@designerfotos.com">
<input type="hidden" name="item_name_1" value="Item Name 1">
<input type="hidden" name="item_number_1" value="Product Model 1">
<input type="hidden" name="amount_1" value="1.00">
<input type="hidden" name="quantity_1" value="1">
<input type="hidden" name="item_name_2" value="Item Name 2">
<input type="hidden" name="item_number_2" value="Product Model 1">
<input type="hidden" name="amount_2" value="2.00">
<input type="hidden" name="quantity_2" value="3">
<input type="submit" value="PayPal">
</form>So my terrible coding has got me editing the checkout_confirmation.tpl to allow for this. But I need to add shipping too. Any geniuses out there that could maybe configure the paypal.php extension to modify it for a shopping cart?
My current code just for ideas... You'll see that I've also taken advantage of the customization of paypal to integrate it into the opencart's design theme:
paypal.php
