When you go long a call you are long : You expect the stock to go up so that you can buy it at a lower price (the exercise)
When you go short a put you again are long : You are giving somebody else the option to sell you the stock at a higher price (a.k.a he is expecting the stock to fall). If you think that the price is going UP then you are going to short (write) a put because you expect the put to expire out of the money hence gaining the premium.
