Conclusion

In this chapter we have considered tasks that touch several layer of the MVC achitecture. First we have seen how to cover extensions for multi languages by adjust static text in the templates and also country-specific formats like date or time are adjusted. In addition we have shown that also the domain model itself can be translated. After this we show the check of invariants in the model, inclusive thedisplay of error messages in the template and the possibility to correct wrong entries by the user. At last we have shown concepts that apply to the security of the extension. Importand by this is tha you have understand what are request hashes and how to prevent against cross site scripting.

Now in the progrss of the book you have get to know Extbase and Fluid intensively. We should not get out of view that these technologies also are bridges to FLOW3 and TYPO3 version 5. The following chapter contains an outlook to FLOW3 and the ongoing development.
