Ajax调用嵌套php文件

Question

我正在对一个ajax文件执行POST请求。让我们称它为A.php

然后，这个A.php文件将调用B.php。

$.ajax({
            type: "POST",
            url: "../../page_components/A.php",
            data: { // my data
            },
            success: function(response) {
                location.reload();
            },

面临的问题:当A.php也调用B时，不会调用成功函数。如果A.php不调用B.php，它就能正常工作

在我的A.php上

/* some stuff that a.php does
*/
include ('B.php'); // call B.php to handle other stuff

B.php

<?php

require '../../../../PHPMailer/class.phpmailer.php';
require '../../../../PHPMailer/class.smtp.php';

// set relevant agency email to send to. $agency comes from A.php
switch ($agency) {
    case "1": $receiverEmail = "xxx@hotmail.com";
    break;
    case "2" : $receiverEmail = "zzz@gmail.com";
    break;
}


$mail = new PHPMailer();

// All the mail setting and stuff is here...
if(!$mail->Send()) {
  echo 'Message was not sent.';
  echo 'Mailer error: ' . $mail->ErrorInfo;
} else {
  echo 'Message has been sent.';
}
?>

Answer 1

url: "../../page_components/A.php"

这是我应该在B.php上发送的网址吗？如果是这样的话，网址就不应该是这样的

url: "../../page_components/B.php"
