I am implementing the web service for mobile phone(Like ios, adnroid etc). I dont have login/signup through facebook in my App. But i want to share the data from my App to facebook (and twitter ) as a post. For this, i dont want to redirect user to facebook to enter their credentials on facebook and then share the data. My requirement is get only Username and password from the user save it in DB and call the FB API from my webservice which will check for the authentication of the user credentials (Facebook ) and if correct then it will psot the data / message to user FB wall. I am trying with php for this , but all the libraries and codes available, are going for FB login window.
I know that offline facebook access is removed, but still want to go for it.
Please, one guide me for this. Any code for php or code for mobile (Iphone and Android) will work
