我有一个表单和一个自定义PayPal按钮,但是如何将值/价格变量传递给PayPal?
<form action="https://www.paypal.com/cgi-bin/webscr" method="post">

<input type="hidden" name="hosted_button_id" value="ZEFZFYBY2SZB8">
<input type="image" src="https://www.paypal.com/en_US/i/btn/btn_paynowCC_LG.gif" border="0" name="submit" alt="PayPal - The safer, easier way to pay online!">
