[TYPO3] Creation of a Header Extension

[Marc Scheib]

Dear Mailing-List!

I am new to the development of the Typo3 System. By now I read  
through the tutorials 1 & 2 and managed successfully to setup a small  
webpage from my templates that displays the content defined in the  
backend as desired.

My wish is now to extend the pages of the website to display a page  
specific flash header. The videos on the Typo3 Documentation page  
explain the creation of such a header in the tutorial "Dan's Flash  
Header".

The tutorial requires the Extension Kickstarter Extension which I  
installed without any visible errors from the repository. Under the  
Extension Manager I have now the desired Menu option to create new  
Extensions, but no output in the frontend is displayed. If I change  
the type of my header back to Normal the frontend display my header  
as usual.

I followed precisely kaspers instructions given in the video except I  
did not upload my extension to the repository. These are the steps I  
performed:

1. Create a new Extension in the the Extension Manager by selecting  
'Make new extension' from the menu.

2. Enter an Extension key on the following page:  
'cocomos_flash_header' and press the button 'update'.

3. Add 'General Info' like Title, Description, Category and State.  
Author Name and Email were already filled with my data.

4. Under 'Frontend Plugins' I enter a title for my extension and  
select the option 'extension as new header type' as described in the  
video.

5. I update the Information and press 'View Result' to save the  
extension to the path recommended by Typo3

6. The following screen reports a success of the operation

7. Still on the Extension Manager page I select 'edit Files' to edit  
the generic output defined in the class created by the kickstarter.

8. It seems it does not really matter whatever I enter for the return  
value, nothing of the stuff I enter gets displayed in the frontend.

9. Save changes

10. create Content with my newly created extension in the backend


Most of the pages I used for editing looked like kaspers screenshots  
in the tutorial video. My Typo3-Backend is capable to create Content  
of the desired type but the Frontend does not show anything.

The HTML source code shows only an empty DIV tag where my header  
should appear:


	<!--  CONTENT ELEMENT, uid:28/header [begin] -->
		<a id="c28"></a>
		<!--  Header: [begin] -->
			<div class="csc-header csc-header-n1"></div>

		<!--  Header: [end] -->
			
	<!--  CONTENT ELEMENT, uid:28/header [end] -->


Has anyone a clue where I am going wrong?

My Typo3-Server has the version 4.0.3 and I installed the extensions  
mentioned in the first and second tutorial.

Regards,
Marc
