Not sure if this helps at all or not but I tried adding the following to the eStore_cart.php file on line 180:
179 $output .= ‘<input type=”image” src=”‘.$checkout_button.'” name=”submit” class=”eStore_paypal_checkout_button” alt=”Checkout” />’;
180 $output .= ‘<input type=”hidden” name=”custom” value=”‘ . $_COOKIE . ‘” />’;
181 $output .= ‘</form>’;
When I view go to that page via an JROX affiliate link http://www.prontopage.net/affiliates/jrox.php?id=1963_1 and then view the source on the cart page I can see:
<tr><td colspan=’2′ style=’font-weight: bold; text-align: right;’>Total: </td><td style=’text-align: left’>$0.25</td><td><form method=”post” action=”” ><input type=’image’ src=’http://prontopage.net/googlelocalsearch/wp-content/plugins/wp-cart-for-digital-products/images/empty-shopping-cart-icon.png’ class=’eStore_empty_cart_button’ value=’Empty’ title=’Empty Cart’ /><input type=”hidden” name=”reset_eStore_cart” value=”1″ /></form></td></tr><tr><td colspan=’4′><input type=”checkbox” name=”t-and-c” class=”t-and-c” value=”” /><label for=”t-and-c”> I agree to the Terms & Conditions</label><label class=”t_and_c_error” for=”t-and-c” id=”t_and_c_error”>You must agree to the Terms & Conditions!</label><form action=”http://prontopage.net/googlelocalsearch/wp-content/plugins/wp-cart-for-digital-products/eStore_payment_submission.php” method=”post”><input type=”hidden” name=”eStore_gateway” id=”eStore_gateway” value=”paypal” /><input type=”hidden” name=”eStore_url” id=”eStore_url” value=”http://prontopage.net/googlelocalsearch/wp-content/plugins/wp-cart-for-digital-products” /><input type=”image” src=”http://prontopage.net/googlelocalsearch/wp-content/plugins/wp-cart-for-digital-products/images/paypal_checkout.png” name=”submit” class=”eStore_paypal_checkout_button” alt=”Checkout” /><input type=”hidden” name=”custom” value=”1963%23%23%231%23%23%230%23%23%230%23%23%23Unknown” /></form></td></tr></table></div>
</div></div>
I see that “custom” is there and there is a value in the “value” field (Is that a cookie? When I clear cookies in my browser, reload the page and view source again I see (name=”custom” value=””), so I am guessing it is… But the debug file the “custom” variable looks empty. See:
