在wooccommerce中应该触发webhook之后，尝试跟踪为什么不发送电子邮件的错误



我想知道为什么在Wooccommerce中购买后，有时webhook似乎会启动，有时却不会。

根据我的理解，有一个自定义插件应该添加到wooccommerce插件webhook的custom topic中，它添加了以下代码(我将把整个代码放在下面(

function add_new_webhook_topics( $topics ) {
// New topic array to add to the list, must match hooks being created.
$new_topics = array( 
'order.gift_card' => __( 'Order Gift Card', 'woocommerce' ),
);
return array_merge( $topics, $new_topics );
}
add_filter( 'woocommerce_webhook_topics', 'add_new_webhook_topics' );

有两个文件，一个是插件，我所能告诉的是，它目前所做的就是将自定义主题添加到webhook下拉选项中，这样我们就可以在成功下订单时启动webhook。然而，有时它会触发webhook，有时并不像我所说的那么远。我这么说的原因是，在将有效载荷发送到礼品卡平台，然后返回礼品卡并发送电子邮件后，应该从网络挂钩中触发电子邮件。

首先是插件PHP代码。我认为额外排队的脚本是计划中的功能，但仍然不确定。

// Will only return one product Id or false if there is zero or many

现在我不知道这是否真的在向礼品卡平台发送有效载荷，或者webhook是否在做所有的工作。我很困惑，因为礼品卡平台是在webhook中调用的，在这个插件中，希望有人能帮助澄清这个插件中发生了什么，而不是基于主题启动webhook。

这是webhook

这就是我的问题所在。我不知道邮件的原因($to，$subject，$message，$headers(；永远不会被发送是因为webhook无法提交到礼品卡服务器，并且在礼品卡服务器端出现错误，或者是因为这个webhook未能发送电子邮件。或者如果这个网络挂钩从未被启动。

现在，为了帮助调试，如果这个webhook的邮件函数从未发送过，那么它发送的时间大约是我通过将订单状态从处理更改为已完成来发送的时间的一半。然而，这应该只适用于内部。我们确实希望礼品卡信息自动发送，但我想有一种方法可以自定义操作，从wooccommerce的订单页面重新发送这个网络挂钩。就像一个按钮或其他东西，上面写着重新发送礼品卡电子邮件。

那么，我想了解的是，在webhook或插件中，提交到礼品卡服务器的真正有效负载在哪里以及为什么webhook电子邮件只提交一半的时间，然后当我在wooccommerce中更改订单状态时会提交另一半的时间。

这里也有JS脚本，但我认为它们目前没有任何作用。

check-balance.js

jQuery(document).ready(function($) {
// checks card balance
$('.gi-check-balance').submit(function() {
var gx_card_number = $(this).find('[name=card-number]').val()
var gx_card_pin = $(this).find('[name=card-pin]').val()
$.ajax({
url: gi_check_balance.ajax_url,
type: 'post',
data: {
action: 'gi_check_balance',
gx_card_number: gx_card_number,
gx_card_pin: gx_card_pin
},
dataType: 'json',
success: function(response) {
console.log(response)
$('.gi-check-balance-result').text(response['result'][2])
//$('.gi-check-balance-result').text(JSON.stringify(response))
$('.gi-check-balance-result').show()
}
})
return false
})
})

secure-register.js

jQuery(document).ready(function($) {
// registers gift card
$('.gi-secure-register').submit(function() {
var gx_register_amount = $(this).find('[name=register-amount]').val()
$.ajax({
url: gi_secure_register.ajax_url,
type: 'post',
data: {
action: 'gi_secure_register',
gx_register_amount: gx_register_amount
},
dataType: 'json',
success: function(response) {
//$('.gi-secure-register-result').html('Reference Number: ' + response['result'][2] + '<br>' + 'Card Number: ' + response['result'][3] + '<br>' + 'Card Amount: ' + response['result'][4])
$('.gi-secure-register-result').text(response)
$('.gi-secure-register-result').show()
}
})
return false
})
})
