Bundle Developer's Guide

Since Pimcore utilizes the powerful Symfony Bundle system, let us refer to the Symfony Bundle Documentation on how to get started with your custom bundles. A bundle can do anything - in fact, core Pimcore functionalities like the admin interface are implemented as bundles. From within your bundle, you have all possibilities to extend the system, from defining new services or routes to hook into the event system or provide controllers and views.

Bundle Directory Structure​

See Bundle Directory Structure for a standard bundle directory layout.

Pimcore Bundles​

There is a special kind of bundle implementing Pimcore\Extension\Bundle\PimcoreBundleInterface which gives you additional possibilities. These bundles provide a similar API as plugins did in previous versions:

  • The bundle shows up in the pimcore:bundle:list command with info if the bundle can be installed or uninstalled.
  • The bundle can be installed with pimcore:bundle:install or uninstalled with pimcore:bundle:uninstall to trigger the installation/uninstallation (e.g. to install/update database structure).
  • The bundle adds methods to natively register JS and CSS files to be loaded with the admin interface and in edit mode.

See the Pimcore Bundles documentation to get started with Pimcore bundles.

Generating Pimcore Bundles​

With the Pimcore Bundle Generator, we provide a tool for generating bundle skeletons. You can install and activate this bundle in your development instance and simplify starting the Pimcore bundle development.

# generate bundle interactively
$ bin/console pimcore:generate:bundle

# generate bundle with a given name and don't ask questions
$ bin/console pimcore:generate:bundle --namespace=Acme/FooBundle --no-interaction

Common Tasks​

Below is a list of common tasks and how to achieve them inside your bundles.

Service Configuration​

If you want to provide custom services from within your bundle, you must create an Extension to load your service definitions. This topic is covered in detail in the Extensions Documentation.

You can find an example of how to create an extension for your bundles in Loading Service Definitions.

Auto-Loading Config and Routing Definitions​

Bundles can provide config and routing definitions in Resources/config/pimcore which will be automatically loaded with the bundle. See Auto loading config and routing definitions for more information.

i18n / Translations​

See the Symfony Translation Component Documentation for locations that will be automatically searched for translation files.

For bundles, translations should be stored in the Resources/translations/ directory of the bundle in the format locale.loader (or domain.locale.loader if you want to handle a specific translation domain). In most cases, this will be something like Resources/translations/en.yml, which resolves to the default messages translation domain.

Example: admin.en.yml or messages.en.yml

Translations Domain​

A translation domain is only considered valid when it is registered as follows:

pimcore:
    translations:
        domains:
            - site_1
            - site_2

Then only translations stored in a dedicated domain table e.g. translations_DOMAIN are used by the Pimcore translation service.

Security / Authentication​

You can fully use the Symfony Security Component by auto-loading the security configuration as documented above. The best practice is to define the security configuration in a dedicated security.yaml, which can be imported from your bundle's config.yaml.

For further details on security please refer to Security.

Events​

To hook into core functions, you can attach to any event provided by the Pimcore event manager. Custom listeners can be registered from your bundle by defining an event listener service. Further reading:

Local Storage for Your Bundle​

Sometimes a bundle needs to save files (e.g. generated files or cached data, ...). If the data is temporary and should be removed when the Symfony cache is cleared, please use a directory inside the cache directory. The core cache directory can be fetched from the Kernel and is registered as a parameter on the container:

  • $kernel->getCacheDir()
  • %kernel.cache_dir% parameter

If you need persistent storage, create a unique directory in PIMCORE_PRIVATE_VAR, e.g. var/bundles/YourBundleName.

Extending the Admin UI​

The following section explains how to design and structure bundles and how to register for and utilize the events provided in the PHP backend and the Ext JS frontend: Event_Listener_UI
