source code for fb like button as gate for downloading file

Step 1:

To detect weather a user has clicked like edge.create is used

Code:

FB.Event.subscribe('edge.create',function(response) {

download();

});

Step 2:

If suppose the user have already liked the page,following code is used to handle it.

Code:

FB.api("me/likes/sourabhsomani1992", function(response) {

if ( response.data.length == 1 ) { //there should only be a single value inside "data"

download();

} else {

//do nothing

}});

Step 3:

We need to hide the download url from the front end.Hence a ajax call is did to get the download link in the download function

Code:

$.post("download.php",{url:"http://www.facebook.com/pages/Webtutsinfo/sourabhsomani1992"}, function(data) {

location.href=data;

$("#like").fadeOut();

});
