how to change price or qty in orderform programmatically

[kuzniz]

Hi,

 

I would like to determand programmaticallythe price/qty when preforming an order with the orderforms , I treid to change the values on the "products" by issueing a

{php}$this->_tpl_vars['pricing']['rawpricing']['monthly']= '60.0';{/php}

 

command but with no success also I can not change the qty programticly as it must press the "update " button in the view.tpl

 

 

is there another way to do it ?

 

regards
