Facebook share information on site

I'm working on a site, where users answer a question, and selects some informations by checkboxes.

Then I'd like to add the wellknown func开发者_运维百科tion, where you click "Share on Facebook", and the anwer and selected information is posted on Facebook like:

"Hi. I answered the question {question} and I think the right answer is {answer}. Try it yourself on url.com to win a great price" ... or something...

What is this called? I looked into Facebook Developer-site, but I couldn't find it...

Thank you in advance.
