WP表单处理程序不是由POST触发的

Question

I have a piece of code that is not working. It is a handler for POST submission. Below is the code sending data.

$.ajax({
  type: 'POST',
  url: '/calculator.php',
  data: $('form').serialize(),
  success: function(data) {
    console.log(data);
  }
});

The handler - calculator.php looks like:

<?php
$parse_url = explode('wp-content', $_SERVER['SCRIPT_FILENAME']);
require_once($parse_url[0], 'wp-load');
send_email();
echo 'success';

function sendEmail() {
  ..
  wp_mail($to, $subject, $message, $headers);
}
?>

When calculator.phps is being invoked from the command line, it works fine. However, submitting the from with ajax or postman does nothing. I have a varnish cache in front of my server, but it should not matter. Should it?

Answer 1

Put the calculator.php file in the root of the wordpress installation with the following changes. and use this path as your ajax url

calculator.php

<?php
require_once('wp-load.php');
send_email();
echo 'success';

function sendEmail() {
  ..
  wp_mail($to, $subject, $message, $headers);
}
?>
