When I was training my 3 yr old I let him run around the house naked from the waist down. I tried training pants and he'd just use them like diapers. This way I could see if he had to go. We only had once pee accident where I saw him going and surprised him that made him stop, grabbed his hand and we ran to the toilet. After he went, lots of praise, hugs, clapping and a sticker chart. He picked up on it really quick.
Poop on the other hand is a different story. After he had mastered the peeing (BTW at first the only way he'd pee was by sitting on the toilet with out a kid seat) he pooped in the toilet and was very scared by it. After that he started holding it and becoming constipated. I had to speak with his pediatrician who gave us a script for a stool softener. After one day and one really gross accident, he got it.
It takes lots of time and lots and LOTS of patience.
