提交后条纹导致错误500

Question

我正在使用Stripe（高级结帐）和PHP。我在输入测试卡详细信息时收到的错误500表示不知所措。

我可以确认PHP版本是7 +

我的代码是：

<script>
var handler = StripeCheckout.configure({
    key: 'XXXXXXXXXXXXXXXXXXXXXXX',
    image: 'https://stripe.com/img/documentation/checkout/marketplace.png',
    token: function(token) {
    var $theToken = $('<input type=hidden name=stripeToken />').val(token.id);
    $('form').append($theToken);
    $("#stripeAmount").val(Math.floor($("#stripePence").val() * 100));
    var path = "<?php bloginfo('template_url');?>/charge.php"; 
        $.post(path, $("form").serialize(), function (data) {
            if (data == "success") {
                alert("Success");
            }
            else {
                alert(data);
            }
        });
    }
});

$('#submit').on('click', function(e) {
    var stripeAmount = Math.floor($("#stripePence").val() * 100);
    var displayAmount = parseFloat(Math.floor($("#stripePence").val() * 100) / 100).toFixed(2);
    var stripeEmail = $('#email').val();
        handler.open({
        name: 'Demo Site',
        description: 'Custom amount ($' + displayAmount + ')',
        currency: 'gbp',
        email: stripeEmail,
        amount: stripeAmount,
        });
  e.preventDefault();
});

$(window).on('popstate', function() {
    handler.close();
});
</script>

Charge.php

<?php
try {
  require_once('config.php');

    $email = $_POST['stripeEmail'];
    $token = $_POST['stripeToken'];
    $total = $_POST['stripeAmount'],

    $err = array();

    $customer = \Stripe\Customer::create(array(
      "email" => $email,
      "source" => $token,
    ));

    $charge = \Stripe\Charge::create(array(
        "customer" => $customer->id,
        "amount" => 1000,
        "currency" => "gbp",
        "description" => "Payment for Flowers"
    ));

} catch (\Stripe\Error\ApiConnection $e) {
    $err[] = $e->getMessage();
} catch (\Stripe\Error\InvalidRequest $e) {
    $err[] = $e->getMessage();
} catch (\Stripe\Error\Api $e) {
    $err[] = $e->getMessage();
} catch (\Stripe\Error\Card $e) {
    $err[] = $e->getMessage();
}
/*Count errors (if any)*/
if(count($err)) {
    foreach($err as $one_er){
        echo $one_er . "<br/>"; 
    }
exit();
}

if (empty($err) === true) {
    echo "success";
}
?>

查看console.log，stripeName，stripeEmail，stripeToken和stripeAmount都被发送到charge.php了。

我试图让用户选择各种可以改变价格的选项（因此可以作为变量）。

是否有其他人看到我遗失或做错的事情？

非常感谢
