我在我的网站上使用paypal付费按钮：www.sakkadentrainer.ch/payment.html
我有一个测试网站：test.sakkadentrainer.ch/payment.html
（对不起，我甚至不确定我是否使用ipn或pdt）
无论如何，它工作正常，但是一段时间（也许1-2周）它就停止了工作。
问题是我没有从paypal获得任何$ _POST内容：
b_search这会返回一个空结果......
array（0）{} 所以表格是用php和html完成的：
if(isset($_GET['show']) && $_GET['show'] == "paypal_process" &&
isset($_POST)) {
var_dump($_POST);
die();
}
}
所以提交我已经用jquery和php保存了电子邮件地址：
<form id="paypal_form" name="_xclick" class="paypal" style="border:0px solid black" action="https://www.sandbox.paypal.com/cgi-bin/webscr" method="post" target="_top" onsubmit="return save_ppp();">
<input type="hidden" name="rm" value="2">
<input type="hidden" name="business" value="b.rentr....ail.com">
<input type="hidden" name="cmd" value="_xclick">
<input type="hidden" name="item_name" id="paypal_itemname" value="1 Lizenz http://test.sakkadentrainer.ch">
<input type="hidden" name="amount" id="paypal_amount" value="">
<input type="hidden" name="item_number" id="item_number" value="2">
<input type="hidden" name="quantity" id="quantity" value="1">

<input type="hidden" name="return" id="return_url" value="http://test.sakkadentrainer.ch/payment.html?show=paypal_process">
<input class="paypal" type="hidden" name="on0" value="Name">
<input id="paypal_email" required name="os0" class="input_username big_input" type="email" placeholder="Ihre E-Mail Adresse" autocapitalize="off" autocorrect="off" value="">
<br/>
<br/>
<input id="paypal_submit" type="image" src="https://www.paypalobjects.com/de_DE/CH/i/btn/btn_buynowCC_LG.gif" type="submit" alt="Paypal" title="Jetzt einfach, schnell und sicher online bezahlen – mit PayPal"> <img class="paypal" alt="" src="https://www.paypalobjects.com/de_DE/i/scr/pixel.gif" width="1" height="1">
</form>
然后在paypal everthing工作正常，与我的沙箱（也现场（我今天收到付款）），但后来我有以下PHP代码的问题：
抱歉很长...但问题是我甚至没有从paypal获得任何数据......function save_ppp(evt) {
evt.preventDefault();
$.ajax({
url: "inc/run_sql.php",
data: {
typ: "save_ppp",
m: $('#paypal_email').val(),
p: $('#paypal_amount').val()
},
type: "GET",
context: document.body,
success: function(data) {
var ppp_error = data.substr(0, 5)
if (ppp_error != 'Error' && ppp_error > '') {
hide_popup();
$('#pp_custom').val(data);
$('#paypal_form').attr('onsubmit', '');
// set cancel return url
$('#cancel_return').val($('#cancel_return').val() + data);
// submit
$('#paypal_form').submit();
show_loading_screen();
} else {
// show paypal alert!
alert($('#save_ppp').text());
}
},
error: function(jqXHR, textStatus, errorThrown) {
//if fails
console.log('Error: ' + jqXHR.responseText);
alert('Error (update_train)');
}
});
return false;
}
**这里的脚本已经来了**
if(isset($_GET['show']) && $_GET['show'] == "paypal_process" && isset($_POST)) {
所以任何人都可以帮助或解释我为什么＆＃34;突然＆＃34;该脚本不再起作用了......

但是我收到了这个错误：
由于卖家网站存在问题，PayPal无法处理此交易。请直接与卖家联系以解决此问题。
