Buttons in Reports OR Link with Submit

Question

Hi,
I have a simple Report. I want a column with a X sign to delete a single row. As far as I understand, there is a form around every report called "wwv_flow". I can not submit the page via URL. It is not entering the Page Processing Section. I tried this:
select
'<img src="#IMAGE_PREFIX#delete.gif" border="0" alt="Delete the file">' "delete", w.id,
w.filename,
s.subject
from wwv_flow_files w , file_subjects s
where w.name = s.name
Is there a way to do this, or is there a way to have buttons rendered in reports for submiting and processing single rows?

Answer 1

Juergen,
There are two ways I can suggest you implement this:
1) Make the delete link go to another page in your application which acts as a delete confirmation page. If you pass along the primary key of the row in question, you can create a process there to make the delete happen.
2) Similar to what you are trying to do, but in stead of trying to emulate a submit or POST, simply loop back to the same page that the report is on. The key here is to use the f?p URL syntax to set the REQUEST value, which can be inspected in a condition on a process. So, you'll have a before header process on the report page, which deletes a row based on a primary key set in P1_ID and this process is conditional on the value of REQUEST being equal to DELETE.
