Now we had to admit that this is working but had nothing to do with the eGroupware style of coding applications. So Ralf told us to do the same thing a bit more the eGroupware style.
Sure, there is the [[Coding-Standards|Coding-Standards]], the [[Developer Guide|Developer Guide]] and the [[Style Guide|Style Guide]]. You should have a look at thoose.
[[Coding-Standards|Coding-Standards]] tell you about how some rules that the eGroupware developers would like you to follow.
[[Developer Guide|Developer Guide]] is to improve eGroupware's usability reflecting the user's needs and being able to implement any necessary modifications as effortless as possible.
[[Style Guide|Style Guide]] is to give you a guideline how to design your application.
Taking these into account, you can easily see, that our first approach is messy.
on our way to the eGroupware campsite, our first encounter with the class
You probably remember the required folderstructure to meet the needs of eGroupware to recognise
our application.
Remember the folder /inc?
The usual way eGroupware deals with userinterfaces, userrequests and stuff is through classes.
The common classes for an application are:
* User Interface Class
* Business Object Class
* Storage Object Class
The names for these classes follow a naming schema in order to enable the eGroupware libraries
the recognition of your own application classes.
* class.test_ui.inc.php for the User Interface Class
* class.test_ui.inc.php for the Business Object Class
* class.test_so.inc.php for theStorage Object Class
The classname of the class should meet the classname you use in the filename. But
most important is, do NOT use just ```class.{ui|bo|so}.inc.php```, as the
class-names have to be unique! There is a reason for this. If you have a look how class-functions are called from
eGroupware (e.g. as menuaction), you will understand the need.
If you design an application the eGroupwareway the index.php file is reduced to something like this:
```php
<?php
header('Location: ../index.php?menuaction=test.test_ui.testinterface');
```
This means, anybody calling your application from within eGroupware is redirected
to the egroupware/index.php with a request for a certain menuaction.
The $_GET['menuaction'] parameter is taken into account, split and evaluated in the
* form that it gets validated there is an application test in eGroupware
* within test there is a classfile class.test_ui.inc.php in test/inc with the class test_ui
* within that class test_ui there is a public callable function testinterface
By now there is no such class in the file nor the required function or the stuff we did not know about at this time.
So we created a class.
We created the required function testinterface.
We added the functionality.
