Theres an motor oil leak that caused the entire engine to drain

What is your question?

While I was driving on the freeway, the engine started to smoke. I pulled to the nearest gas station and the engine wasn't overheated (I checked and it was half way) the oil spit out to the side of the right tire and towards the underneath of the truck. Even got on the tail gate and inside the back of the truck. Filled the engine with nearly 3 bottles of oil. Checked to see any leaks and started the car, the engine was not leaking. Started it up just fine, drove barely a mile and it stalled on the freeway. Car still turns on, didn't blow the head gaskets. Just the oil leak. The oil splattered on right side of the vehicle underneath by the tire. How can I fix this?
