PayPal的折扣不能使它的工作 [英] PayPal discount can't make it work

问题描述

我尝试使用PayPal + Codeigniter为整个购物车设置折扣，我得到了折扣。

阅读我唯一需要做的是设置一个隐藏字段 discount_amount_cart ，因为我看到这里

这是我的表单：

 < form method =postaction =https://www.sandbox.paypal.com/cgi-bin/webscrname =paypal_form> ; 
< input type =hiddenname =rmvalue =2/> 
< input type =hiddenname =cmdvalue =_ cart/> 
< input type =hiddenname =uploadvalue =1/> 
< input type =hiddenname =currency_codevalue =EUR/> 
< input type =hiddenname =businessvalue =[e-mail]/> 
< input type =hiddenname =returnvalue =http://xxxxxx.com/website/pt/paypal/success/8/4c237a03897e0/> 
< input type =hiddenname =cancel_returnvalue =http://xxxxxxx.com/website/pt/paypal/cancel/8/4c237a03897e0/> 
< input type =hiddenname =notify_urlvalue =http://xxxxxx.com/website/pt/paypal/ipn/> 
< input type =hiddenname =customvalue =/> 
< input type =hiddenname =no_shippingvalue =1/> 
< input type =hiddenname =cpp_header_imagevalue =http://xxxxxxxxx.com/images/logo.png/> 
< input type =hiddenname =image_urlvalue =http://xxxxxxxxx.com/images/logo.png/> 
< input type =hiddenname =invoicevalue =4c237a03897e0/> 
< input type =hiddenname =no_notevalue =1/> 
< input type =hiddenname =discount_rate_cartvalue =10.00/> 
< input type =hiddenname =first_namevalue =Foo Bar/> 
< input type =hiddenname =cityvalue =xxxx/> 
< input type =hiddenname =address1value =xxxxxx/> 
< input type =hiddenname =zipvalue =xxxxxx/> 
< input type =hiddenname =lcvalue =pt/> 
< input type =hiddenname =emailvalue =[e-mail]/> 
< input type =hiddenname =countryvalue =PT/> 
< input type =hiddenname =item_name_1value =Cloud Hosting WIN Business 25GB/> 
< input type =hiddenname =item_number_1value =200.00000003/> 
< input type =hiddenname =amount_1value =156/> 
< input type =hiddenname =quantity_1value =1/> 
< input type =hiddenname =tax_rate_1value =20/> 
< p>< input type =submitname =pp_submitvalue =Pagarclass =submit/>< / p& 
< / form>  

但是当我发布

干杯

从PayPal文件：

使用合并折扣金额时，应在tax_cart中指定合并税金值。如果您没有指定税金值，而且您的个人资料指定了税率，则在应用合并折扣值后应用您的个人资料税率。

因此，我需要使用 tax_cart 定义我的全球税额。

I'm trying to setup a discount for a the whole cart using PayPal + Codeigniter, I got this working withouth the discounts.

As far as I've read the only thing that I would need to do is set a hidden field discount_amount_cart as I saw here

Here is my form:

<form method="post" action="https://www.sandbox.paypal.com/cgi-bin/webscr" name="paypal_form">
     <input type="hidden" name="rm" value="2" />
     <input type="hidden" name="cmd" value="_cart" />
     <input type="hidden" name="upload" value="1" />
     <input type="hidden" name="currency_code" value="EUR" />
     <input type="hidden" name="business" value="[e-mail]" />
     <input type="hidden" name="return" value="http://xxxxxx.com/website/pt/paypal/success/8/4c237a03897e0" />
     <input type="hidden" name="cancel_return" value="http://xxxxxxx.com/website/pt/paypal/cancel/8/4c237a03897e0" />
     <input type="hidden" name="notify_url" value="http://xxxxxx.com/website/pt/paypal/ipn" />
     <input type="hidden" name="custom" value="" />
     <input type="hidden" name="no_shipping" value="1" />
     <input type="hidden" name="cpp_header_image" value="http://xxxxxxxxx.com/images/logo.png" />
     <input type="hidden" name="image_url" value="http://xxxxxxxxx.com/images/logo.png" />
     <input type="hidden" name="invoice" value="4c237a03897e0" />
     <input type="hidden" name="no_note" value="1" />
     <input type="hidden" name="discount_rate_cart" value="10.00" />
     <input type="hidden" name="first_name" value="Foo Bar" />
     <input type="hidden" name="city" value="xxxx" />
     <input type="hidden" name="address1" value="xxxxxx" />
     <input type="hidden" name="zip" value="xxxxxx" />
     <input type="hidden" name="lc" value="pt" />
     <input type="hidden" name="email" value="[e-mail]" />
     <input type="hidden" name="country" value="PT" />
     <input type="hidden" name="item_name_1" value="Cloud Hosting WIN Business 25GB" />
     <input type="hidden" name="item_number_1" value="200.00000003" />
     <input type="hidden" name="amount_1" value="156" />
     <input type="hidden" name="quantity_1" value="1" />
     <input type="hidden" name="tax_rate_1" value="20" />
     <p><input type="submit" name="pp_submit" value="Pagar" class="submit" /></p>
    </form>

But when I "post" the fields the discount line won't appear, do I need to activate something in the merchant account, am I doing something wrong?

Cheers

解决方案

Got it,

From the PayPal documentation:

When you use consolidated discount amounts, you should specify a consolidated tax value in tax_cart. If you do not specify a tax value and your profile specifies a tax rate, your profile tax rate is applied after the consolidated discount value is applied.

So I need to define my "global" tax amount for the cart with tax_cart.
