Accessing user's Facebook checkins via Graph API

Your application might want to use a user’s checkin data in various ways, I outline below how to fetch a user’s facebook checkin information and get the Facebook page for that location.

First of all, you need to have the permissions to access a user’s checkin data. Look at http://developers.facebook.com/tools/explorer for information on this.

Once you have the required permissions and the user is logged in via Facebook connect:

//dojo.hitch to make the object scope available
FB.api("/me/checkins", dojo.hitch(this, function(response){
	if(response.data && response.data.length > 0) {
		dojo.forEach(response.data, function(item) {
            var locationId = item.id; 
            var locationName = item.place.name; //name of the place
            // To get a Facebook link to the location
            var locationLink = this.getLocationLink(locationName, locationId);
            console.log(locationLink); //print location link
        });
	}
}));

/**

*/
getLocationLink: function(locationName, locationId) {        
        var baseURL = 'http://wwww.facebook.com/pages/';
        var locationNameArr = locationName.split(' ');
        var locationLink = '';
        for(var i = 0; i < locationNameArr.length; i++) {
            locationLink += locationNameArr[i];
            if(i != locationNameArr.length-1) locationLink += "-";
        }        
        return baseURL + locationLink + '/' + locationId;
    },
    

More information on whats available with the Checkin object is outlined here: http://developers.facebook.com/docs/reference/api/checkin/

The /me/checkins request usually returns the most recent 25 checkins, with a hook to access more of the checkin information if required.
