Calling a function from inside a view

[eluser]Omaplie[/eluser]
Thank you a lot for all your help.

Sorry, I am not sur to understand everything.
Yes, I need a function like you say.

I'll put this function into the helper but no need
to call the controler ?

Is this method respect the MVC ?
It's not a trouble if it's not the case, it's just to know.

I'll try your solution by putting this function into the helper
but how can I call the function in the view, with parameters ?

Many thanks.
