The Basics

Important

Configuration is tightly related to the service container.
To fully understand the following content, you need to be aware of Symfony's service container and its configuration.

Basic configuration handling in eZ Publish is similar to what is commonly possible with Symfony. Regarding this, you can define key/value pairs in your configuration files, under the main parameters key (like in parameters.yml).

Internally and by convention, keys follow a dot syntax where the different segments follow your configuration hierarchy. Keys are usually prefixed by a namespace corresponding to your application.
Values can be anything, including arrays and deep hashes.

eZ Publish core configuration is prefixed by ezsettings namespace, while internal configuration (not to be used directly) is prefixed by ezpublish namespace.

Dynamic configuration with the ConfigResolver

In eZ Publish, it is fairly common to have different settings depending on the current siteaccess (e.g. languages, view provider configuration).

Scope

Dynamic configuration can be resolved depending on a scope.

Available scopes are (in order of precedence) :

  1. global
  2. SiteAccess
  3. SiteAcces group
  4. default

It gives the opportunity to define settings for a given siteaccess, for instance, like in the legacy INI override system.

This mechanism is not limited to eZ Publish internal settings (aka ezsettings namespace) and is applicable for specific needs (bundle related, project related, etc).

ConfigResolver Usage

Dynamic configuration is handled by a config resolver. It consists in a service object mainly exposing hasParameter() and getParameter() methods. The idea is to check the different scopes available for a given namespace to find the appropriate parameter.

In order to work with the config resolver, your dynamic settings must comply internally to the following name format : <namespace>.<scope>.parameter.name.

 

Namespace + scope example

Both getParameter() and hasParameter() can take 3 different arguments:

  1. $paramName (i.e. the name of the parameter you need)
  2. $namespace (i.e. your application namespace, myapp in the previous example. If null, the default namespace will be used, which is ezsettings by default)
  3. $scope (i.e. a siteaccess name. If null, the current siteaccess will be used)

Inject the ConfigResolver in your services

You can use the ConfigResolver in your own services whenever needed. To do this, just inject the ezpublish.config.resolver service:

Custom locale configuration (5.1+)

If you need to use a custom locale they can also be configurable in ezpublish.yml, adding them to the conversion map:

ezpublish:
    # Locale conversion map between eZ Publish format (i.e. fre-FR) to POSIX (i.e. fr_FR). 
    # The key is the eZ Publish locale. Check locale.yml in EzPublishCoreBundle to see natively supported locales.
    locale_conversion:
        eng-DE: en_DE

A locale conversion map example can be found in the core bundle, on locale.yml.
