Little case study on using static file cache to increase performance of TYPO3
The average number of requests on www.t3node.com is growing more and more. Since the website is hosted on a tiny virtual machine shared with others, the overall server performance is bad. Today I decided to serve pages from file cache to reduce the load. This little case study describes the problem by example and gives some key data for illustration. -
Fixed broken comment form on this site (update)
The comment form of this blog was broken the last two days. The reason was that I disabled the no_cache parameter in the install tool. It seems the ve_guestbook extension somehow relies on this parameter. The comments are now working properly again. Sorry for the inconvenience. -
Using the new TCA wizard "suggest" for autocompletion in BE fields of TYPO3 4.3
There's a new type of wizard in the TYPO3 core called "suggest", which has been added to TCA with 4.3beta-1. This wizard adds a magic input field for autocompletion to fields of type "group" or "select", also called find-as-you-type. It helps to quickly find a record by typing its name/title in the suggest field, getting an AJAX dropdown list with all possible results. This article demonstrates how to implement this wizard in your TYPO3 extension. -
Save-and-view button for records of TYPO3 extensions
When editing a page in the TYPO3 backend, there's a whole bunch of save buttons available. The "save document and view page" button allows to save the content and open a preview popup with one click. Unfortunately this does only work for regular pages and content elements, but not for database records of extensions which are stored inside sysfolders. The following tutorial describes a way to get that button also running for those records. -
Dynamic forms and types with TYPO3 FlexForms
The most accessible way to configure a plugin in TYPO3 is using a custom content element build with FlexForms. It provides forms of all kinds for any BE user. FlexForms adapt most of the features of the TCA, but unfortunately the documentation on FlexForms is rather poor. The following article tries to demonstrate the configuration of a TYPO3 FlexForm in order to get some forms which dynamically change their fields on user interaction. -
Book review of "TYPO3 Extension Development" by Dmitry Dulepov
The market for english books on TYPO3 is still very thin - compared to german books. This possibly depends on the great popularity TYPO3 enjoys in germany. Unfortunately a lot of these german books are oversized. Few of them are concentrating on one audience (editors, administrators, developers) and their specific task, but covering the full range of topics on TYPO3. For a TYPO3 extension developer that meant to skip 3/4 of the content of most books. In contrast, "TYPO3 Extension Development" by Dmitry Dulepov, recently published by Packt Publishing has chosen a different approach. -
Add CSH to TYPO3 FlexForm fields

How to add context sensitive help (CSH) items to TYPO3 extension modules
Software documentation is often rare and developers are lazy, when writing manuals instead of code. TYPO3 comes with a built-in help system which can easily be used to explain items directly in the backend. Dear lazy coder, let's have a look at it! -
How to create a page browser in TYPO3 extensions?
Hugh data listings can be confusing and hard to understand. That applies to search results as well as news collections, members directory or todo lists. Page browser divide listings into several parts, which make it much easier to keep track of the data. The following article describes and compares two approaches to integrate a page browser in TYPO3 extensions. -
Security issue in TYPO3 Extension Secure Directory (kw_secdir)
Today, the TYPO3 security team released a collective security bulletin. Since I am the author of one extension which was listed in the bulletin (kw_secdir), I'd like to comment this a little bit. Especially the severity of "high" sounds evil, but it's IMHO less dangerous than some might think. -
addPItoST43?
TYPO3 sometimes drives me nuts. It happens that I come across cryptic function or property names, using them over and over again without having a clue, what its name stands for. t3lib_extMgm::addPItoST43() is one of them, although it is part of almost a billion TYPO3 extensions... -
