Craftcms

Craft CMS 5 plugin and module development — extending Craft with PHP. Covers the full extend surface: elements, element queries, services, models, records, project config, controllers, CP templates, migrations, queue jobs, console commands, field types, native fields, events, behaviors, Twig extensions, utilities, widgets, filesystems, permissions, debugging, testing, GraphQL, and Craft configuration (config/app.php, config/general.php, Redis, SMTP, database replicas). Triggers on: beforePrepare(), afterSave(), defineSources(), defineTableAttributes(), attributeHtml(), MemoizableArray, getConfig(), handleChanged, $allowAnonymous, $enableCsrfValidation, BaseNativeField, EVENT_DEFINE_NATIVE_FIELDS, FieldLayoutBehavior, EVENT_REGISTER, EVENT_DEFINE, EVENT_BEFORE, EVENT_AFTER, CraftVariable, registerTwigExtension, DefineConsoleActionsEvent, PHPStan, Pest, plugin development, module development, custom element type, custom field type, webhook, API endpoint, queue job, batch processing, data sync, migration, CP section, control panel, Craft plugin, Craft module, extending Craft, element action, element exporter, element condition, dashboard widget, utility page, permissions, registerUserPermissions, requirePermission, GraphQL custom types, GraphQL custom mutations, GraphQL schema building, Rector, Craft 4 to 5, upgrade plugin, CI/CD, GitHub Actions, GitLab CI, custom validator, defineRules, EVENT_AUTHORIZE_VIEW, EVENT_AUTHORIZE_SAVE, canView, canSave, canDelete, element authorization, defense-in-depth, query scoping, EVENT_BEFORE_PREPARE, session invalidation, passwordResetRequired, elevated session, Table::SESSIONS, custom field type build, field type development, normalizeValue, serializeValue, inputHtml, BaseCondition, ElementCondition, condition rule, condition builder, system messages, composeFromKey, email sending, Mailer, deployment, zero-downtime deploy, atomic deploy, craft up, project-config/apply, allowAdminChanges, drafts, revisions, provisional draft, canCreateDrafts, applyDraft, getIsDraft, getIsRevision, App::env, App::parseEnv, CRAFT_CP_TRIGGER, CRAFT_DEV_MODE, CRAFT_ALLOW_ADMIN_CHANGES, GeneralConfig, config precedence, cpTrigger. Always use when writing, editing, or reviewing any Craft CMS plugin or module PHP code — even when the user asks about plugin architecture, Craft internals, or extending Craft without naming specific APIs. Do NOT trigger for front-end Twig templates, content modeling decisions, site-building without PHP, or consuming GraphQL/headless APIs from front-end frameworks (Next.js, Nuxt, Astro) — those belong in craft-site.
