Use Whoops as Exception handler for TYPO3

During development for TYPO3 you often run into Exceptions. They do not look very nice. A much nicer alternative might be whoops which @dk2kde told me about. It will not only handle exceptions, but also PHP Errors like syntax errors.

In this small blog post I will show you how to use whoops as exception handler for TYPO3 projects during local development. The result will be:

How to create TYPO3 Form select element with options selected from database

TYPO3s new form framework allows to write custom form elements. This way you are able to define a new select element, based on the existing one, but filled with options fetched from database.

E.g. you want your user to select from sys_cateogy or some other custom records. In this blog post I will show how to provide the necessary logic in a custom PHP class, how to register a new element extending the existing one and how to use this new element in your forms.

How to crypt submitted values using a custom finisher in TYPO3 CMS 8

Since TYPO3 CMS Version 8 there is a new Form framework heavily inspired by Neos Form Framework. As most parts of Neos / Flow it’s a great heavy dynamic component with great power.

In this post I will show how easy it is to write a custom finisher to crypt submitted values using the SaltedPasswords extension. This enables you to write fe_user registration forms without the need of 3rd party extensions.

TYPO3 (Extbase) Injection

TYPO3 provides a way of dependency injection. This way you do not need to resolve dependencies inside of your code, but the framework will resolve and provide the dependencies for you. This is provided by the framework Extbase, back ported of Flow.

The main benefit is the flexibility. Using Interfaces to define dependencies, instead of concrete classes, it’s possible to exchange injected dependencies just by configuring the framework. This way you can exchange classes in 3rd party code and receive a huge flexibility. Same goes for testing your code. In this Post I will show you the different ways to make use of dependency injection inside of TYPO3 and provide help for edge cases.

Using PHP_CodeSniffer for automated code migrations

PHP_CodeSniffer is a command line tool allowing to check php, js and css. The main use case is to check code styles like the popular PSR-2. Beside checking coding styles, some communities are already using this tool for further checks like direct access to global variables like $_POST instead of using the provided API, e.g. take a look at Magento PHP_CodeSniffer Coding Standard. Also there is a standard to check compatibility of the code with PHP versions.

Beside this use cases and huge benefits, there is another use case: automated code migrations that can be achieved using PHP_CodeSniffer. In this blog post I will provide the necessary basics and an example how to auto migrate your PHP code using PHP_CodeSniffer.

Build TYPO3 Language Menu without the need of optionSplit

TYPO3 CMS allows you to build a language menu to enable the frontend user to switch the current language. This menu is generated via TypoScript using optionSplit. Just start a query and take a look at the snippets. This way has one big drawback. In a multi domain setup you have to change the config

We have overcame this issue with one language menu working for all setup on all domains without the need to adjust anything. Read here how to achieve this.

Documentation marketing

During my contributions in the area of documentation it turns out most developers have so much fun while developing new features. In the end they are proud of their new product, but don’t provide documentation for their users. Users can be further developers extending the original product via an API, or the user interacting with the product via a GUI or CLI. Sometimes they promote their new product, e.g. a new feature. They write a Blog post, tweet about it, talk on conferences, and so on. But no one else can inform himself about the features and much more important if he once get interested, how to use the product or feature.

Analysing TYPO3 changes via scrapy

Reading a magazine, I was confronted with scrapy »an open source and collaborative framework for extracting the data you need from websites. In a fast, simple, yet extensible way.« The framework is written in python and easy to use. You can persist the information in multiple output formats like xml, json, csv and some more. That makes it easy to fetch structured information like TYPO3 Changelog. Also I had highcharts bookmarked for some years now. The interest in how many changes were introduced in each TYPO3 Version, in combination with the type of change, like breaking change or feature, were the missing idea to put everything together.

In this post you will learn a minimum setup to put scrapy and highcharts together, to visualize information like the mentioned above.

TYPO3 Custom DevLog

TYPO3 ships with a debugging process called DevLog. It’s a function provided by the core and used by many extensions. The main purpose is to log information for debugging. Beside the new Core feature Logging with TYPO3, it’s older and therefore used in more extensions. TYPO3 doesn’t ship with a handler for this function, it’s possible to provide handler via TYPO3’s Hooks and Signals mechanism and the popular devlog extension is installed on many TYPO3 installations to have a handler which logs everything to the database and provide a backend module to see the entries. But that’s not necessary, you can register your own, very small handler in your AdditionalConfiguration.php or your distribution.

Dynamic, context aware, content generation

There was one talk at the TYPO3 conference this year, with the name “Semantic Annotations within TYPO3 CMS” by Johannes Goslar. The main goal is to prepare content inside TYPO3 CMS with semantic information, so you can deliver it with rich snippets to improve SEO. Beside that, the solution developed offers a way to query all your content by the semantic understanding. Most of us heard about Graphs nowadays, whether from Facebook or Google. They aim to make information understandable by computer and enable users to query information like they normally would in the real world.

Inject TypoScript Settings

Sometimes you need settings like TypoScript in a class which is not your controller. Inside a controller, the Extbase framework already injects the settings for you, so you are able to access them under $this->settings.

In all other classes it’s easy to let Extbase inject the settings for you. Just include the following code, and make sure you instantiate the class via \TYPO3\CMS\Extbase\Object\ObjectManager instead of \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance().

Why needs CMS a fundamental shift? - Alain Veuve

What do your visitors need? Deliver the requested experience. E.G. give them an overview with anchors. Deliver the right information in the right moment. But never ever tell him he don’t need a specific information. You never can cover all use cases. Let the visitor decide what he needs and give him a way to still fetch everything you have on your normal web page.
