TYPO3 and FLOW3 FLOW3 acts as a reliable basis for any kind of web application TYPO3 v5 is a package based on FLOW3 TYPO3 extensions are packages as well, all based on FLOW3 Packages can be used as extensions for TYPO3 as libraries for standalone applications Hitchhiker's Guide to FLOW3 Inspiring people to share Mittwoch, 20.

Getting Started Hitchhiker's Guide to FLOW3 Inspiring people to share Mittwoch, 20. Mai 2009

Getting Started Requirements Some webserver (tested with Apache and IIS) PHP 5.3RC1 or higher (see http://snaps.php.net/) PHP extensions: zlib, PDO and PDO SQLite and the usual stuff Some database (tested with SQLite, MySQL and Postgres) Hitchhiker's Guide to FLOW3 Inspiring people to share Mittwoch, 20. Mai 2009

Getting Started Download Currently available through Subversion Checkout the FLOW3 Distribution: svn co https://svn.typo3.org/FLOW3/distribution/trunk or try the TYPO3 Distribution: svn co https://svn.typo3.org/TYPO3v5/distribution/trunk Nightly builds will follow as soon FLOW3 1.0 alpha 1 release on June 1st Hitchhiker's Guide to FLOW3 Inspiring people to share Mittwoch, 20. Mai 2009

Getting Started Grant File Permissions The webserver needs read access for all ﬁles of the distribution and write access in the Public and Data directory On Linux / Mac just call sudo ./ﬁxpermissions.sh On legacy operating systems: ask your system administrator Hitchhiker's Guide to FLOW3 Inspiring people to share Mittwoch, 20.

Model - View - Controller Hitchhiker's Guide to FLOW3 Inspiring people to share Mittwoch, 20. Mai 2009

The MVC Pattern Model an object which contains data and business logic of a certain domain doesn't contain any information about the presentation of that data, but rather deﬁnes the behaviour in the FLOW3 project we prefer a special kind of model, the Domain Model Hitchhiker's Guide to FLOW3 Inspiring people to share Mittwoch, 20. Mai 2009

The MVC Pattern View represents the display of the model on the web or another output channel views only display data, they don't build or modify it Hitchhiker's Guide to FLOW3 Inspiring people to share Mittwoch, 20. Mai 2009

The MVC Pattern Controller reacts on user input, selects and manipulates the model as accordingly selects a view and passes it the prepared model for rendering Hitchhiker's Guide to FLOW3 Inspiring people to share Mittwoch, 20. Mai 2009

MVC Action Controller An action controller accepts a request evaluates arguments calls the action deﬁned in the request and adds output to the response Hitchhiker's Guide to FLOW3 Inspiring people to share Mittwoch, 20. Mai 2009

MVC Action Controller: Important Methods Actions - methods just need an \"Action\" sufﬁx: public function indexAction() { … } public function deleteAction() { … } Initialization for the whole controller: public function initializeController() { … } Initialization before any action is called: public function initializeAction() { … } public function initializeXYAction() { … } Hitchhiker's Guide to FLOW3 Inspiring people to share Mittwoch, 20. Mai 2009

MVC Action Arguments Arguments are deﬁned by declaring them in the action method Argument data types are deﬁned by type hint and documentation /** * Action that displays one single post * * @param \\F3\\Blog\\Domain\\Model\\Post $post The post to display * @return void * @author Robert Lemke <robert@typo3.org> */ public function showAction(\\F3\\Blog\\Domain\\Model\\Post $post) { Hitchhiker's Guide to FLOW3 Inspiring people to share Mittwoch, 20.

Validation Hitchhiker's Guide to FLOW3 Inspiring people to share Mittwoch, 20. Mai 2009

Validating Arguments All arguments passed to an Action Controller are automatically validated White List policy: Only registered arguments are available Accessing the $_GET and $_POST super globals is dangerous, dirty, deprecated and will probably be intercepted in the future Hitchhiker's Guide to FLOW3 Inspiring people to share Mittwoch, 20. Mai 2009

Validating Arguments FLOW3 comes with a bunch of built in validators: AlphaNumeric, EmailAddress, Float, Integer, NotEmpty, Number, NumberRange, RegularExpression, UUID, Text Custom validators can be created (especially for Domain Models) All validators can be chained (and nested) Hitchhiker's Guide to FLOW3 Inspiring people to share Mittwoch, 20. Mai 2009

Validation Rules Definition All validation rules are defined by annotations in place Additional rules may be defined programmatically class Blog { /** * The blog's name. Also acts as the identifier. * * @var string * @validate Alphanumeric, Length(minimum = 3, maximum = 50) * @identity */ protected $name = ''; /** * A short description of the blog * * @var string * @validate Text, Length(maximum = 150) Hitchhiker's Guide to FLOW3 */ Inspiring people to protected $description = ''; share Mittwoch, 20. Mai 2009

Validation Rules Definition /** * Create action for this controller. * * @param string $emailAddress * @return string The rendered view * @author Robert Lemke <robert@typo3.org> * @validate $emailAddress EmailAddress */ public function createAction($emailAddress) { } Hitchhiker's Guide to FLOW3 Inspiring people to share Mittwoch, 20.
