The public API will give you an easy access to the eZ Publish content repository. This repository is the core component that manages content, locations (former Nodes), sections, content types (former Content Classes), user groups, users and roles. It also provides a new, clear interface for plugging in custom field types (former Datatypes).
The public API is built on top of a layered architecture including a new persistence layer for abstracting the storage functionality. By using the public API, your applications will be forward compatible with future releases based on enhanced,  scalable and high-performance storage engines. Applications based on the public API are also fully backwards compatible by using the included storage engine based on the current kernel and database model.

Get Started

Recipe 1 - Setting up a sample command line symfony bundle using the public API

This recipe shows a good practice how to use the public API inside the eZ Publish 5 installation by using the symfony console component. Inside the cookbook,  all code runs inside a symfony command which is inside a symfony bundle. It is now shown how to setup a simple symfony bundle with a commandline script using the public API. The command is executable within the ezpublish/console and dumps a content object for a given content id.

Go to the eZ publish installation

cd <ezpublish installation root>

Generate a new Bundle

php ezpublish/console generate:bundle

Now follow the instructions. This will create a bundle EzSystems/CookBookBundle in the src directory of the installation root (Note: this bundle exists already so a different namespace will be required).

Add a Command directory to the bundle

cd <ezpublish installation root>/src/EzSystems/CookbookBundle

mkdir Command

add the following class file CookbookCommand.php in the directory Command


my first command

run f.e.

php ezpublish/console cookbook:run  5


Creating and editing Content

The following recipes show how to create simple content. As we don't want to rely on a specific installation with predefined content types we first show how to create a content type group and a simple content type within this group. Then we will create a content object of the newly created content type. The last two recipes show how to create content containing images and xml text.

Recipe 2 - Creating a content type group

This snippet creates a content type group for a given identifier (Full code here).

create content type group


If this snipped is run with the same init code from recipe 1 we will get an UnauthorizedException.

The solution is described in the next recipe.

Recipe 3 - Setting the user for authorizing actions

By default the repository assumes the anonymous user is acting. To change this the following code can be executed


If the user is identified by other mechanisms the user also can be loaded by its id via the service method


Recipe 4 - Creating a content type

With this snipped a content type with two fields of type 'ezstring' is created. (Full code here).

create content type


Recipe 5 - Creating content

In this recipe content is created under a given parent location. It is assumed that the loaded content type is the one created in recipe 4. (Full code here).

create content


Recipe 6 - Updating Content

In this recipe the previously created content is updated with a new title and body in the same language. (Full code here)

update content

Recipe 7 - Translating content

It is the same code as for updating (see recipe 6). The initial language should be set to the translation language.


Recipe 8 - Multiple translations at once

It is possible to to make an update in content  or create content with more than one language. But there is a restriction - only one language can be assigned to the newly created version (which is displayed in the 4.x admin GUI in the translations column).

update multiple languages

Recipe 9 - Creating Content containing an image

This recipe shows how to create an  content object containing an image. (Full code here)

creating an image


Recipe 10 - Create Content with XML Text

This recipe shows how to create content with xml text. As content type the folder is used where the description is filled with xml. It is also shown how to embed the previously created image in the description. The image Id is given by a command line argument.

Browsing, Finding, Viewing

Recipe 11 - Viewing Content

This recipe shows how to view fields of the content int the main language.

viewing content


Other languages are accessible via the the language parameter in the method

$content->getField( $fieldDefinition->identifier, $otherlanguage)


Recipe 12 - Browsing Locations


This recipe shows how to browse a subtree starting from a given location. (Full code here)


browse locations




The method browseLocation





Recipe 13 - Viewing Content Meta Data

This recipe shows how to read content meta data: Locations, UrlAliases, Relations, Versions, Contenttype, Section, Owner, RemoteId, Several Timestamps. (Full code here)

viewing content meta data

This script produces e.g the follwing output:


Recipe 14 - Performing a simple full text search

In this recipe a simple full text search is performed. (Full code here)

a simple full text search


Recipe 15 - Performing an advanced search

In this recipe different criteria is combined using a logic 'AND' operation. The result is restricted additional (see recipe 9) to a given content type and subtree. (Full code here)



Working with locations

Recipe 16 - Adding a new location to content

This recipe shows how to add a new location to a given content object. (Full code here)

add location

Recipe 17 - Move or Copy Subtree

This recipe shows how to move or copy a subtree to a given parent location (Full code here)

copy/move location

Recipe 18 - Hide/Unhide Location

This recipe shows how to hide/unhide a location. (Full code here)

hide/unhide location

Recipe 19 - Deleting locations

If a content has more than one location the method

LocationService::delete(Location $location) 

removes the location and if exists all descendants of the location. However the content itself is untouched as it has still other locations.

If the deleted location is the last one of the content the content itself is deleted. This applies also to all descendants of the location.

Alternatively a location can also moved to the trash via the method:

TrashService::trash(Location $location)

Other Recipes

Recipe 20 - Deleting Content

The result of deleting content permanently  is equivalent to deleting all locations of content (see recipe 15).

It is done via the method:

ContentService::delete(ContentInfo $contentInfo)

Recipe 21 - Assinging section to content

On creation of content  the section of the parent location's content is assigned by default to the new content. However it is possible to assign a specific section on creation by setting it in the ContentCreateStruct (recipe 5):

$contentCreateStruct->section = $sectionId

Later on sections can be assigned with the following code (Full code here):

assign section to content
