  • How to get an access token to access Facebook open graph

    If you want to develop something for or with Facebook, you always need an access_token. Facebook provides different access tokens, most of them are received using OAuth. But for command line tools and development there is another way to receive the tokens.

    For our example we have a hidden Facebook page. We want to retrieve photos of this page through a PHP command line tool. Therefore we create an app at https://developers.facebook.com/ .

  • 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.

  • Talk: Writing NeoVim Plugins using Python Plugin API

    This talk will be held at Vimfest 2017 in Berlin. I’ll show how to write plugins for Nvim using the new Python Plugin API. The API is async and wraps the new msgpack. The API is called “Remote Plugin API”.

    As an example I will use the plugin neotags, which is my first Nvim plugin using the new API. It’s completely written in Python3 and covered with tests. Of course there are already some tag update plugins out there, but I wanted to try out the new API. Also most of the plugins did not work with my setup, or contain to much code and no tests.

  • 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.

  • Talk: Introduction to Git for daily usage

    This talk will be held at Vimfest 2016 in Berlin. It will introduce you to Git and provide the minimum necessary information to get started using Git on a daily basis.

    This post is about the content of the talk and a basic introduction without the hands on.

  • 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.

  • TYPO3 Developer Days 2016 in Nuremberg - Recap

    The TYPO3 Developer Days 2016 in Nuremberg took place from 01. Sep to 04. Sep in the youth hostel of Nuremberg. During these days multiple prepared talks were presented, together with a coding night of the Core Team where everyone could jump in.

    In this post I’ll recap the event and some talks I’ve participated on. All talks that were recorded during the event are available on Youtube as playlist T3DD16 - TYPO3 Developer Days 2016.

  • 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.

  • How to find Hooks in TYPO3

    Hooks inside of TYPO3 CMS allow you to hook into existing processes of the core, or of extensions, to manipulate the processes.

    This post will explain in more depth what hooks are and how you can find and use them.

  • Flow’s embedded expression language (Eel)

    Flow provides different packages, one is the Eel package the embedded expression language. A developer can use Eel to generate a domain specific language, (=DSL). Neos, the CMS built upon Flow, uses Eel to parse parts of their TypoScript 2. Also I’ve heard of one using Eel to generate QR-Codes. Myself has used Eel like Vim auto command for filetype detection. There is a wide range of use cases where Eel can be used.

    In this blog post you get a short introduction into the basics to understand how and when to use Eel.

  • Workflow for: Read the docs, Sphinx and Plantuml

    Documentation was never easier, with a Framework like Sphinx and a hoster like Read the docs. All you need is a repository containing your Documentation written with Sphinx and an account at Read the docs. Plantuml can be used in addition to generate UML-Diagrams using plain text. The result can be SVG files in the same color as your Documentation. The whole setup and workflow for that will be explained in this Blog post. After reading the post, you are able to kickstart a new documentation and host it at Read the docs. You then can dig deeper and adjust it to your needs.

    A first result after kickstart and first generation.
  • 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 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.

  • Everything is Content, that can be served via Solr

    TYPO3 provides some record types like pages, content, files and categories. With this basic set of record types you can build full blown websites containing products, projects, Blog posts, news and many more different content types without the need of any plugins, it’s just configuration in TYPO3.

  • Folder specific settings in Vim

    If you are like me, you have a structured filesystem for your different jobs. E.g. one for your own projects, one for customers, one for learnings, etc. This allows you to set specific options within Vim related to the projects or customers. E.g. if typo3 uses tabs instead of spaces you can configure that for Projects/typo3/**. And if you want to ignore certain folders like build within Sphinx installations, but not within e.g. typo3 projects, you can do it like the following.

  • Tmux

    Tmux is a nice tool. Most people already know screen, and tmux is like screen a terminal multiplexer.

  • Why not to be afraid of asking customers to pay for technical dept

    An alternative name for this post could be: I definitely have to learn to take less, or to be happy with less perfectly work. As I had to finish a new feature for one of our customers today, while being at the TYPO3 conference in Amsterdam, I took a look at the time tracking. This feature took five hours of time to be implemented. Everything he requested was to implemented a Newsletter registration with double opt in for a lottery game. Of course the customer already has a registration with double opt in for the newsletter. So the only task I had to do, was to bring the information from lottery form to the newsletter. Sounds like a small deal and it actually was. But where does the time come from?

  • T3CON15 Day 1 - The agile conference

  • 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().

  • OS X Terminal colors and fonts

    If you’re using the OS X build in terminal, you wanna change the colors. The default colors aren’t that nice. Instead of changing them manually and figure out a nice set of colors, just grab an existing color scheme for the app. Here are some links with nice color schemes ready to use for you.

  • 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.

  • Versioning / revert old files

    Even Dropbox has a versioning system that allows you to restore deleted files and folders or revert an older version of a file. What a nice feature. But you can have it even without Dropbox for your local file management. Just try one of the modern version system. There are even nice GUI applications for them so it’s easy to use and setup.

  • TYPO3 XLIFF for Extension Development

    Since TYPO3 4.5 it’s possible to use the new XLIFF-Format for translation. There is a very nice article about the differences and usage in the internet. Take a look at it. After reading I had some more question. I’ll try to answer them now in this post.

  • Easy ImageMagick on Mac

    I don’t know why there are so many articles about installing ImageMagick on a Mac for TYPO3. All you have to do is to install Homebrew (The missing package manager for OS X). After installing (this takes 1 Minute), just run:

  • Mac OS X, use the native Apache/PHP

    I found out how to start the built in Apache in Mac OS X Lion (10.7.x) with standard configuration.

  • Sorting a multidimensional array with array_multisort

    We first need the array we want to sort (here called arrayToSort). Secondly we need a second array containing the values we want to sort. In this case our names. I called the array arrayWithNamesToSort.
