我开发了一个wordpress插件，它是一个表单生成器。该插件允许用户输入列表ID，API ID，名字，姓氏和电子邮件地址变量，以便在提交表单时将表单提交同步到选定的mailchimp列表。
我有这个工作，但最近注意到它不再向mailchimp发送信息。
检查我的调试文件，我收到以下错误：
[03-Mar-2017 11:53:47 UTC] PHP Notice: Undefined index: emailId in .../plugins/layers-form-builder/includes/class-send-form.php on line 37
[03-Mar-2017 11:53:47 UTC] PHP Notice: Undefined index: emailSubject in .../plugins/layers-form-builder/includes/class-send-form.php on line 38
[03-Mar-2017 11:53:47 UTC] PHP Notice: Undefined index: mcListID in .../plugins/layers-form-builder/includes/class-send-form.php on line 41
[03-Mar-2017 11:53:47 UTC] PHP Notice: Undefined index: mcAPIkey in .../plugins/layers-form-builder/includes/class-send-form.php on line 42
[03-Mar-2017 11:53:47 UTC] PHP Notice: Undefined index: formData in .../plugins/layers-form-builder/includes/class-send-form.php on line 54
这是在提交表单时触发的脚本，它通过ajax处理数据：
<script>
jQuery(document).ready(function($) {
$('#layers-widget-form_builder-17 .builderForm').each(function() {
$(this).on("submit", function(event) {
event.preventDefault();
var formData = $(this).serialize();
var emailId ='sam.skirrow@gmail.com';
var emailSubject ='New website form submission';
var mcListID ='2d2fbcd34d';
var mcAPIkey ='7f306818ee8b588162a7be1ac72d213b-us10';
var mcEmail = $(this).find('input[name="email"]').val();
var mcLname = $(this).find('input[name="last_name"]').val();
var mcFname = $(this).find('input[name="first_name"]').val();
var mcForm = $(this);
$('#layers-widget-form_builder-17 .builderForm').addClass('loading');
$.ajax({
type : 'POST', // define the type of HTTP verb we want to use (POST for our form)
url : 'http://thedistractionsband.co.uk/wp-content/plugins/layers-form-builder/includes/class-send-form.php', // the url where we want to POST
data : {'formData' :formData,'emailId':emailId, 'emailSubject':emailSubject, 'mcListID':mcListID, 'mcAPIkey':mcAPIkey, 'mcEmail':mcEmail, 'mcFname':mcFname, 'mcLname':mcLname}, // our data object
dataType : 'json', // what type of data do we expect back from the server
encode : true
})
.done(function(data) {
// log data to the console so we can see
console.log(data);
//setTimeout(function(){$('#overlay').hide();}, 4000);
//$('#overlay').remove();
$('.successMsg').html('<i class="fa fa-check"></i> Your message has been sent!');
$('.form-builder-submit').hide();
setTimeout(function(){
$('.successMsg').hide();
$('.builderForm').removeClass('loading');
$('.form-builder-submit').show();}, 3000);
// Reset form after submission
$(".builderForm")[0].reset();
})
.fail(function (jqXHR, textStatus) {
console.log(textStatus);
$('.successMsg').html('<i class="fa fa-cross"></i> Oops, there seems to have been an error when submitting the form');
setTimeout(function(){$('.successMsg').hide();}, 3000);
});
event.preventDefault();
});
});
});
</script>
以下是class-send-form.php（包含错误的文件）

// show a message of success and provide a true success variable

// return all our data to an AJAX call
echo json_encode($data);
我的问题似乎存在于以下几个方面：
$layers_email_address = $_REQUEST['emailId'];
$layers_email_subject = $_REQUEST['emailSubject'];
// mailchimp vars
$mc_list_id = $_REQUEST['mcListID'];
$mc_api_key = $_REQUEST['mcAPIkey'];
$mc_email = getIfSet($_REQUEST['mcEmail']);
$mc_fname = getIfSet($_REQUEST['mcFname']);
$mc_lname = getIfSet($_REQUEST['mcLname']);
但是我不确定如何测试/调试此问题，我们非常感谢任何帮助，如果需要，我可以添加更多代码段。

将您的所有string更改为$_REQUEST＆＃39>
即
$_POST变为$_REQUEST['emailId']
答案 1 :(得分：0)
就个人而言，我开始使用var_dump（$ _ REQUEST）或var_dump（$ _ POST）来确定这些值是否存在，以及在哪个变量中存在。
