php - 带有价格下拉表的 Paypal 多个项目？

Question

嘿，伙计们，我尝试使用 Paypal 对网站的一部分进行编码，一切都很顺利，直到我需要添加选项，如果客户希望购买额外的商品以及他们想要什么颜色。我可以将选择的颜色发送到 Paypal，但我似乎无法在账单上增加 12.00 英镑的额外价格，我可以选择提前发货，效果很好，只是不确定我哪里出错了？

Answer 1

我不是 100%，但我认为 PayPal 只允许一个包含价格的选择表单，这必须是 os0。

因此您需要将任何价格为 os0 的期权移动，这将与 option_amount0 和 option_select0 相关。

<input type="hidden" name="on0" value="Extra Wheels">
<select name="os0">
  <option value="BLUE" selected>BLUE</option>
  <option value="MORE COLOURS TO BE ADDED">MORE</option>
</select>
<input type="hidden" name="currency_code" value="GBP">
<input type="hidden" name="option_select0" value="BLUE">
<input type="hidden" name="option_amount0" value="12.00">
<input type="hidden" name="option_index" value="0">
