获取错误:使用此表单时缺少的一些必需信息：

<form action="https://www.sandbox.paypal.com/cgi-bin/webscr" method="post" target="_top">
    <input type="hidden" name="cmd" value="_s-xclick">
    <input type="hidden" name="custom" value="$id">
    <input type="hidden" name="hosted_button_id" value="PGZ7LZ2K66GLQ">

我遗漏了什么信息？

Answer 1

您的托管按钮id.May出了问题，错误的字符，或者您使用的是在线贝宝帐户托管id。您可以尝试生成新的按钮，我只是用我的按钮替换了托管的按钮id，它就能工作了。
