10# Moodle AJAX and JavaScript Integration
11 
12## Purpose
13Ensure robust, secure, and maintainable integration between PHP and JavaScript in Moodle.
14 
15## Instructions
16- Use `$PAGE->requires->js()` to load JS modules
17- Use AMD modules for all new JS code
18- Use Moodle's AJAX API for server communication
19- Validate and sanitize all AJAX inputs in PHP
20- Return JSON responses using Moodle's output functions
21- Use `sesskey` for CSRF protection in AJAX requests
22- Document JS/PHP interfaces and data contracts
23 
24## Examples
25```php
26// File: ./amd/src/myplugin.js
27define(['jquery'], function($) {
28    // JS code here
29});
30 
31// File: ./ajax.php
32require_sesskey();
33$param = required_param('id', PARAM_INT);
34echo json_encode(['result' => 'ok']);
35```

37## Exceptions
