How to get JavaScript function data into a PHP variable
Use jQuery to send a JavaScript variable to your PHP file:
$url = 'path/to/phpFile.php';
$.get($url, {name: get_name(), job: get_job()});
In your PHP code, get your variables from $_GET['name'] and $_GET['job'] like this:
<?php
$buffer_data['name'] = $_GET['name'];
$buffer_data['job'] = $_GET['job'];
?>
JavaScript code is executed clientside while PHP is executed serverside, so you'll have to send the JavaScript values to the server. This could possibly be tucked in $_POST or through Ajax.
