Moodle Coding Standards

Write compliant Moodle plugin code following PSR-12 and Moodle-specific conventions.

When to Use This Skill

• Creating new Moodle plugins

• Writing PHP code for Moodle

• Code review and quality checks

• Understanding Frankenstyle naming

See reference.md for complete standards.

Key Rules

Frankenstyle Naming

plugintype_pluginname local_mymodule mod_assignment block_myblock

File Headers

<?php // This file is part of Moodle - http://moodle.org/ // // Moodle is free software...

namespace local_mymodule;

defined('MOODLE_INTERNAL') || die();

Class Naming

// Class in local/mymodule/classes/helper.php namespace local_mymodule; class helper { // Methods use snake_case public function get_user_data() { } }

Quick Checks

• File header with license

• defined('MOODLE_INTERNAL') || die();

• Proper namespace

• PSR-12 formatting

• No direct DB queries (use DML)
