1. Starting with ExtBase

2. Grundaufbau ExtBase/Fluid
Model: Product
• Title
• Price
Repository
• findAll
• findByProperty
Controller
• List
• Show
Fluid Template
• List
Fluid Template
• Show

3. Grundaufbau ExtBase/Fluid
Model
Controller
Fluid Template
public function getTitle() {
return $this->title;
}
public function listAction() {
$products = $this->productRepository->findAll();
$this->view->assign('products', $products);
}
<f:for each="{products}" as="product">
<tr>
<td>
<f:link.action action="show" arguments="{product :
product}">
{product.title}
</f:link.action>
</td>
</tr>
</f:for>

4. ViewHelper
{namespace as=TYPO3AsViewhelperViewHelpers}
Fluid Template
<f:for each="{products}" as="product">
<tr>
<td>
<f:link.action action="show" arguments="{product : product}">
<as:uppercase value="{product.title}" />
</f:link.action>
</td>
</tr>
</f:for>
ViewHelper
class UppercaseViewHelper
extends TYPO3CMSFluidCoreViewHelperAbstractViewHelper
{
public function render($value) {
return strtoupper($value);
}
}

5. Extension Builder

6. Extension Builder

7. Extension Builder: Relations
•
•
•
•
Hauptobjekt: Product – aggregate root
Untertabellen: Color
Relations: Drag & Drop mit dem Kreis
More->Type: 1:1, 1:n, n:1, n:m

8. Verzeichnisstruktur
- Classes
--- Controller
--- Domain
--- ViewHelpers
- Configuration
--- FlexForms
--- TCA
--- TypoScript
- Resources
--- Private
----- Templates
--- Public
----CSS
----JS

9. Konventionen
• phpDoc vor Funktionen
• Camel-Case, Lower-Camel-Case,
Unterstrich,…?
– Class: AsDemoExtbase
– Variable: asDemoExtbase
– Datenbank: as_demo_extbase

10. Datenbank: Repository
• Sehr viele Default-Funktionen:
• findAll = SELECT * FROM table
• findByName($val) =
SELECT * FROM table where name like „$val
• findOneByArticleNo($id)
SELECT … limit 1
• Add, remove, update, replace,
• $query->createQuery; $query->matching(),
constraints, $query->execute
• SQL: $query->statement(„SELECT ….“)

11. ObjectManager
• PHP: new
TYPO3: t3lib_div::createInstance
• Extbase: Singleton, DependencyInjection
• objectManager->get (Controller, Repository)
• objectManager->create (Model), danach im
Repistory: $this->add($obj)
$prod=$this->objectManager->create
('TYPO3Asextbasedemo1DomainModelProduct');
$prod->setTitle("AutoCreated");
$this->productRepository->add($prod);
2 Slashes in Namespace Path!

12. Nice to know
• piBased: $this->pi_getLL('languagekey')
• TYPO3CMSExtbaseUtilityLocalizationUtility::tr
anslate('languagekey', $extensionName)
(extensionName: Ordnername in typo3conf/ext)
