set_value or input->post

[eluser]one4all[/eluser]
Thanks for opinion.

I'm agree seems that set_value has to be used in "write" context...so better in view. And ->input->post in controller...

But as we have set the rule for each elem for a form for example, we have to do same things for input, and (for example) if you set xss_clean, you have to repeat this "treatment" 2 times, for the set_rule value and when you retrieve the input->post value...

Is there a way to optimize those actions ?...
