用PHP构建带有多个项目和PayPal按钮的购物车 [英] Builing a cart with multiple items and the PayPal button in PHP
问题描述
我正在用PHP构建购物车,并希望允许客户输入每种商品的数量,然后按一个按钮,该按钮会将您带到PayPal,并列出您拥有多少商品.
I'm building a shopping cart in PHP and want to allow customers to enter the quantity for each item and then press a button which brings you to PayPal and lists how many products you have.
在PayPal的网站上,我发现的所有信息似乎都导致我需要购物车.如果这绝对必要,我该如何实施?
On PayPal's website, all the info I found seems to lead to me needing a shopping cart. If this is absolutely necessary, how could I implement that?
推荐答案
我只需要这样做.
我在HTML中使用此表单:
I use this form in my HTML:
<form action="https://www.paypal.com/cgi-bin/webscr" method="post" id="payPalForm" onsubmit="if (verify()) { get_items(); return true; } else return false;">
<input type="hidden" name="cmd" value="_cart" />
<input type="hidden" name="upload" value="1">
<input type="hidden" name="business" value="[PAYPAL EMAIL HERE]" />
<input type="hidden" name="currency_code" id="currency_code" value="USD" />
<input type="hidden" name="return" value="http://www.example.com/thank_you_kindly.html" />
<p style="text-align: center">
<input type="submit" name="Submit" value="Join (via PayPal)" id="register_button" />
</p>
</form>
我制作的特定表格还可以通过设置currency_code隐藏字段值来更改货币.
The particular form I made can also change the currency by setting the currency_code hidden field value.
这是我用来添加项目的javascript函数:
Here's the javascript function I used to add an item:
function add_item(item_number, item_name, amount, qty) {
// item number
var inp1 = document.createElement("input");
inp1.setAttribute("type", "hidden");
inp1.setAttribute("id", "item_number_"+curitem);
inp1.setAttribute("name", "item_number_"+curitem);
inp1.setAttribute("value", item_number);
// item name
var inp2 = document.createElement("input");
inp2.setAttribute("type", "hidden");
inp2.setAttribute("id", "item_name_"+curitem);
inp2.setAttribute("name", "item_name_"+curitem);
inp2.setAttribute("value", item_name);
// amount
var inp3 = document.createElement("input");
inp3.setAttribute("type", "hidden");
inp3.setAttribute("id", "amount_"+curitem);
inp3.setAttribute("name", "amount_"+curitem);
inp3.setAttribute("value", amount);
// qty
var inp4 = document.createElement("input");
inp4.setAttribute("type", "hidden");
inp4.setAttribute("id", "quantity_"+curitem);
inp4.setAttribute("name", "quantity_"+curitem);
inp4.setAttribute("value", qty);
document.getElementById('payPalForm').appendChild(inp1);
document.getElementById('payPalForm').appendChild(inp2);
document.getElementById('payPalForm').appendChild(inp3);
document.getElementById('payPalForm').appendChild(inp4);
curitem++;
}
将表单代码粘贴到您的页面中,然后调用添加项功能:
Paste the form code into your page and call the add item function:
add_item('001-新产品','新产品',1,1);
add_item('001- New Product', 'New Product', 1, 1);
您不会看到该产品,但是当您实际将表单提交给Paypal时,它就会在那里.这确实有点hack,它回答了您的问题,但是我会研究paypal专业代码.这应该可以帮助您入门.
You won't see the product, but it will be there when you actually submit the form to paypal. This is really a bit of a hack, it's answers your question, but I would look into the paypal pro code. This should get you started.
