为什么贝宝显示SUCCESS和$ _POST变量贝宝的网站而不是返回我的return_url

Question

Please help me. I'm at a total loss. After more than 2 days of Googling everything I can think of, I still have no answers. This DID work in the Sandbox. My code for sending the tx and token to Paypal.

<form name='verification' action='https://www.paypal.com/cgi-bin/webscr' method='post'>
    <input type='hidden' name='at' value='$atoken' />
    <input type='hidden' name='tx' value='$tx' />
    <input type='hidden' name='rm' value='2' />
    <input type='hidden' name='cmd' value='_notify-synch' />");
    print("<input type='hidden' name='return' value='$returnUrl' />");
    print("<input type='submit' name='submit' value='PDT'>");
print("</form>");

Answer 1

The variable for return url is return_url not return . It should also be an account in your Paypal account.

Answer 2

your amount and tax variables are not being parsed

<input type='hidden' name='at' value='<?=$atoken?>' />
<input type='hidden' name='tx' value='<?=$tx?>' />
