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)
