Content element registry

Typo3 extension simplify process of creating new content elements (CE) in Typo3 way

Install

Install extension via composer composer req digitalwerk/content-element-registry and activate it in Extension module

Setup

After activating extension, you have to define your Content elements configuration classes. It can be done in two ways:

1. By defining paths in extension configuration (aka extConf). Can contain comma separated list of paths to directories Example: EXT:your_ext_1/Classes/ContentElements/,EXT:your_ext_2/Classes/ContentElements/

2. By registering Listener in Services.yaml of your extension as follows:

Method Vendor\Extension\EventListeners\ContentElementRegistryListener can looks like this:

Creating new content element

To create new Content element you have to create new Class inside your folder defined in Setup section which extends Digitalwerk\ContentElementRegistry\ContentElement\AbstractContentElementRegistryItem

After clearing typo3 caches you should now see new content element in wizard

As you can see, there is neither title nor description of the content element. These are automatically fetched and translated from locallang file inside of your extension: EXT:your_extension/Resources/Private/Language/locallang_db.xlf. You can now define your CE title and description as follows:

When you add this new CE it will contain only default CE fields:

Adding CE fields

To add new fields you have to define it in \YourVendor\YourExtension\ContentElement\YourNewContentElement:

By this, we defined new CE palette with name default with two fields header and bodytext.

Code description:

1. Name of the palette must be unique per CE. Label for palette can be defined in locallang_db.xlf with following key: tt_content.yourextension_yournewcontentelement.palette.default
2. Fields definition syntax must follows TCA palette showitem syntax
3. Used fields must be properly configured in tt_content TCA
4. You can add as many palettes as you need ;)

Our CE now should looks like this:

If you need to override field configuration you can do this in this way: (In following example we've enabled rich text editor for bodytext field)

CE Template

Template path of content element must be configured in typoscript as follow:

Template name is matched by CE class name. E.g. if is registered CE with class name YourNewContentElement this template must exists EXT:your_extension/Resources/Private/Templates/ContentElements/YourNewContentElement.html. Content of template can looks like this:

Whether you use <f:layout /> and <f:section /> it's fully up to you. You can also add section <f:section name="Preview"> which is used for BE preview.

CE Icon

If you don't want to use the defaut icon, you can change it:

• Add an icon to the folder EXT:your_extension/Resources/Public/Icons/ContentElement/yourextension_yournewcontentelement.svg

CE Domain Model

Model name is matched by CE class name. E.g. if is registered CE with class name YourNewContentElement this model can exists in EXT:your_extension/Classes/Domain/Model/YourNewContentElement.php Content of model can looks like this:

Into class you can write some functions, getters, setters, etc. Some of them are inherited from DigitalWerk\ContentElementRegistry\Domain\Model\ContentElement (take a look ;).

Model in template

Model is accessible in the template of element with variable name {contentElement}. To find out what data is loaded in the model in the template use: <f:debug>{contentElement}</f:debug>.

Create a new field and setup

Create a new field

1. Create a field in the table ext_table.sql, e.g. new_field.
2. In the TCA EXT:your_extension/Configuration/TCA/Overrides/tt_content.php create new column and config Typo3 Columns Config:

Setup a new field

• In Class \YourVendor\YourExtension\ContentElement\YourNewContentElement add created field new_field:

• In Model of CE EXT:your_extension/Classes/Domain/Model/YourNewContentElement.php add property of created field $newField. You must follow the syntax, e.g. new_field which is written in ext_table.php, you must write newField in the model.

Content element with IRRE

Mapping

Map in ext_typoscript_setup.typoscript relation table to CE model:

Register relation icon

You can register relation icon using Typo3 Icon API

Relation TCA

In TCA EXT:your_extension/Configuration/TCA/Overrides/tx_contentelementregistry_domain_model_relation.php create:

Relation add to CE

Add name of relation to palette:

Relation model

• In model of CE create property and getter:

• Create a new file YourNewRelation.php in \YourVendor\YourExtension\Domain\Model\ContentElement\YourNewContentElement. Here you can write getters and properties for fields in TCA of Relation:

CE field mapping

In Class of CE you can map field, when you want to use it in model, e.g. tx_contentelementregistry_relations is called in the model txContentelementregistryRelation, but after mapping 'tx_contentelementregistry_relations' => 'relations',tx_contentelementregistry_relations is called in the model relations.
