Help with Add to PayPal Cart increment (ASP)

Help with Add to PayPal Cart increment (ASP)

Hi. Need some help with my "Proceed to Checkout" button to PayPal.
I need to pass a name, amount and quantity variable from my cart page, to PayPal, but I need to add an incremental number, beginning with 1, to the variable name.

In PHP, I have the code as:

<? $i = 1;?>
<? foreach ( $cart->items() as $item ) { ?>
<input type="hidden" name="item_name_<?=$i?>" value="<?= _h($item->product()->full_name())?>">
<input type="hidden" name="amount_<?=$i?>" value="<?=$item->product()->price()?>">
<input type="hidden" name="quantity_<?=$i?>" value="<?=$item->quantity()?>">
<? $i++; ?>
<? } ?>

How do I recreate this for Classic ASP, whilst integrating with my eCart Repeat Region?
Here's my eCart Repeat Region, without the incremental code:

<%
while (NOT WA_eCart_EOF(spCART))
%>
<input type="hidden" name="item_name_1" value="<%=WA_eCart_DisplayInfo(spCART, "Name")%> - <%=WA_eCart_DisplayInfo(spCART, "Description")%>">
<input type="hidden" name="amount_1" value="<%=WA_eCart_DisplayInfo(spCART, "Price")%>">
<input type="hidden" name="quantity_1" value="<%=WA_eCart_DisplayInfo(spCART, "Quantity")%>">
<%
set spCART = WA_eCart_MoveNext(spCART)
wend
set spCART = WA_eCart_MoveFirst(spCART)
%>

Also, I wondered if there was anything I could add that would prompt a user if they edited the quantities of an item in their eCart but forgot to click the 'Update' cart button, and subsequently then tried to click the 'Proceed to Checkout' button?

Appreciate the help, thanks.
Nath.

a simple way to get the correct code to use is to create a test page and add an ecart checkout form for paypal payments standard to it.

go to Insert -> eCart -> Checkout Form. Select the remote checkout option, and select Paypal Payments Standard from the checkout type.

This checkout form will have the code you are looking for.

can't progress

Hi Jason. Thanks for getting back to me.

The eCart > Checkout Wizard (not Form) is trying to insert a whole load of content I don't need though. For example, it's creating a form asking for billing information which I don't need because PayPal is handling all that.
It's also trying to create other pages such as confirm.asp, checkout_success.asp and checkout_failure.asp.

Anyway, it's created the following code which, concerningly, is nothing like the form I already have on my website. Perhaps someone could help me pick through it?

<%spCART_Index = spCART.DisplayIndex - 2%>
<%
while (NOT WA_eCart_EOF(spCART))
%>
<%spCART_Index = spCART_Index + 1%>

<% 'WA eCart Validation
if ((WA_eCart_FormatNumber(WA_eCart_DisplayInfo(spCART, "Price") - ((WA_eCart_DisplayInfo(spCART, "Price")/WA_eCart_TotalColumn(spCART, "TotalPrice")) * WA_eCart_GetDiscounts(spCART)), false, 2) > 0)) then
%>
<input type="hidden" name="amount_<%=spCART_Index+1%>" id="amount_<%=spCART_Index+1%>" value="<%= WA_eCart_FormatNumber(WA_eCart_DisplayInfo(spCART, "Price") - ((WA_eCart_DisplayInfo(spCART, "Price")/WA_eCart_TotalColumn(spCART, "TotalPrice")) * WA_eCart_GetDiscounts(spCART)), false, 2) %>" />
<input type="hidden" name="item_name_<%=spCART_Index+1%>" id="item_name_<%=spCART_Index+1%>" value="<%=WA_eCart_DisplayInfo(spCART, "Name")%>" />
<input type="hidden" name="item_number_<%=spCART_Index+1%>" id="item_number_<%=spCART_Index+1%>" value="<%=WA_eCart_DisplayInfo(spCART, "ID")%>" />
<input type="hidden" name="quantity_<%=spCART_Index+1%>" id="quantity_<%=spCART_Index+1%>" value="<%=WA_eCart_DisplayInfo(spCART, "Quantity")%>" />
<input type="hidden" name="on0_<%=spCART_Index+1%>" id="on0_<%=spCART_Index+1%>" value="" />
<input type="hidden" name="os0_<%=spCART_Index+1%>" id="os0_<%=spCART_Index+1%>" value="" />
<input type="hidden" name="on1_<%=spCART_Index+1%>" id="on1_<%=spCART_Index+1%>" value="" />
<input type="hidden" name="os1_<%=spCART_Index+1%>" id="os1_<%=spCART_Index+1%>" value="" />
<% 'WA eCart Validation
else
spCART_Index = spCART_Index - 1
end if
%>
<%
set spCART = WA_eCart_MoveNext(spCART)
wend
set spCART = WA_eCart_MoveFirst(spCART)
%>

What parts of the above code do I need with the more simplified form I have listed in my original post above? For example...

What is the difference between <%spCART_Index = spCART.DisplayIndex - 2%> and <%spCART_Index = spCART_Index + 1%>?

What is WA eCart Validation?

What are the 4 new variables the wizard has created?:
on0_<%=spCART_Index+1%>
os0_<%=spCART_Index+1%>
on1_<%=spCART_Index+1%>
os1_<%=spCART_Index+1%>

I don't really like using the WebAssist wizards because, in the past, I've had nothing but trouble with them. I also don't like the fact that I can't select "none" for the CSS styling and, therefore, end up with a lot of redundant CSS code.

I'd appreciate any advice that could be offered, thanks.
Regards
Nath.

I dint suggest to use the checkout wizard.

I suggested creating the checkout form only.


you can remove any of the form elements that code is creating that you dont want to use.

"What is the difference between <%spCART_Index = spCART.DisplayIndex - 2%> and <%spCART_Index = spCART_Index + 1%>?"

none. it's a different way to do the same thing.

the 4 new variables that are created are used for passing variable data to paypal, if you dont need them, then you can remove them.

oops

Sorry Jason, I read your post as Checkout Form which is, in actual fact at:
Insert > WebAssist > eCart > Insert Checkout Form, not, Insert -> eCart -> Checkout Form. My mistake.

What is WA eCart Validation?

Appreciate your help, thanks.

Nath.

i assume you are referring to this code:

<% 'WA eCart Validation
if ((WA_eCart_FormatNumber(WA_eCart_DisplayInfo(spCAR T, "Price") - ((WA_eCart_DisplayInfo(spCART, "Price")/WA_eCart_TotalColumn(spCART, "TotalPrice")) * WA_eCart_GetDiscounts(spCART)), false, 2) > 0)) then
%>


it's a check to make sure that the price and total price are valid.
