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.
Receipt 1 - Setting up a sample commandline symfony bundle which uses the public API
This receipt shows how to setup a simple symfony bundle with a commandline script using the public API. The command is executable within the app/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 app/console generate:bundle
Now follow the instructions. This will create a bundle eZ/Publish/Bundle/CookBookBundle in the src directory of the installation root.
Add a Command directory to the bundle
cd <ezpublish installation root>/eZ/Publish/Bundle/CookbookBundle
add the following class file CookbookCommand.php in the directory Command
php app/console cookbook:run 5
Receipt 2 - Creating a content type group
This snippet creates a content type group for a given identifier.
If this snipped is run with the same init code from receipt 1 we will get an UnauthorizedException.
The solution is described in the next receipt.
Receipt 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
Receipt 4 - Creating a content type
With this snipped a content type with two fields of type 'ezstring' is created.
Receipt 5 - Creating content
In this receipt content is created under a given parent location. It is assumed that the loaded content type is the one created in receipt 4.
Receipt 6 - Updating Content
In this receipt the previously created content is updated with a new title and body in the same language
Receipt 7 - Translating content
It is the same code as for updating (see Receipt 6). The initial language should be set to the translation language.
Receipt 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).
Receipt 9 - Performing a simple full text search
In this receipt a simple full text search is performed.
Receipt 10 - Performing an advanced search
In this receipt different criteria is combined using a logic and operation. The result is restricted additional to a given content type and subtree.
