App FB and PHP

Hello, I need a job with FB APP and PHP. In a FB tab the user must be able to write in a form a solution. If the solution is correct, the app automatically will post on the page of the company and the user's personal profile and then insert some data (name age and date of response) on a page winners. If the answer is wrong, the app automatically on the page company will post only the wrong answer, without having to write the user name. Responses are attached video. Example. User sees a video, want to try the answer. If the answer is correct, you will have a post (page and profile) in which it will say: "Charlie Brown failed to respond correctly to the video X1" and then the data will be inserted into a picture winners. If the answer is wrong there will be a post (page) to which it will say: "A user has tried to solve the X1 video writing: test test test" It will work inside a tab fb and mobile device (iphone android)
