Here is what I need. I have a few payment methods on site.
Need to include E-Junkie. So when my customer goes to a checkout page, can choose how want to pay.
If choose E-Junkie, need to use item id and quantity from cart what choose on site. I have made everything, but now need to update &i and &quantity on the button for each item from the cart
<a href="javascript:EJEJC_multiAdd(Array(
'https://www.e-junkie.com/ecom/gb.php?c=cart&ejc=2&cl=XXXXXX&i=YYYYYY',
'https://www.e-junkie.com/ecom/gb.php?c=cart&ejc=2&cl=XXXXXX&i=ZZZZZZ'
));"><img src="http://www.e-junkie.com/ej/ejadd_to_cart.gif" alt="Add to Cart" border="0"/></a>
When click on the button need to go on E-Junkie page and make payment, in E-Junkie page need to have all products like from site.
I have the same products on site and on E-Junkie, if on the site ID for product is 10 on E-Junkie for same product ID is 145821
If you not understand, I will try to explain it better.
