[TYPO3-dev] Overwriting header field with fixed content - How to do it?

[Jens Beckmann]

Hi!

How could I fill a headline field with fixed content?

In my particular case I want each download section (CType "uploads") on 
the website to appear with the same heading, e.g. "Files to download", 
no matter what the user has filled into the header field in the backend 
form.

I think I could build the whole rendering on my own (tt_content = CASE 
...) but is there an easier way to overwrite the content coming from the 
database field "header" where CType is "uploads"? I am using static 
template "CSS Styled Content".

Thank you for any hint!
