[TYPO3-ttnews] A news counter in LIST view ?

[Gregory Loichot]

Hello,

Thank you, but in fact it is not what I want to do. In my HTML code, 
there won't be a list of *all* news because there is a limit in the sql 
query (no more than 5). So, JS cannot "know" how many news there are.

I have to do this in PHP code. In tt_news, there is a hook 
(processSelectConfHook) to construct your own sql query, but after that 
you can only act on *each* query result, so you cannot know how many 
news there are (or I don't know how :)).

Any idea ?
