如何通过ajax调用将数据从2个不同的页面发送到php？

Question

So I need the user to fill a form and then I want to pass that data to another page like so

Site1

<form action="site2.php" method="post">
Name: <input type="text" name="name">
Email: <input type="text" name="email">
<input type="submit">
</form>

Site2 will read the name and email from site1 and include it inside a ajax call

Site2 Javascript

function addMarker(location, map) {
        // Add the marker at the clicked location
        var marker = new google.maps.Marker({
          position: location,          
          map: map
        });

        $.ajax({
          url: 'insertToDatabase.php',
          type: 'POST',
          data: { lat: location.lat(),
                  long : location.lng(),
                  name : $_POST['name'], // something like this
                  email: $_POST['email'] // something like this
                }
        });
      }

Is there a way to do something like this for the Ajax call? Thanks!

Answer 1

Sure. in site2, just capture the POST vars, then ask PHP to print their values wherever you need it

site2.php

<?php
//capture the POST vars
$name = $_POST['name'];
$email = $_POST['email'];
?>
...HTML & JS code GOES HERE....

Then later on down the page, where your ajax function is, you can re-enter PHP mode to output the values:

$.ajax({
    url: 'insertToDatabase.php',
    type: 'POST',
    data: { lat: location.lat(),
    long : location.lng(),
    name : '<?= $name ?>',
    email: '<?= $email ?>'
    ...
