Using facebook javascript sdk to process fql query

Question

I have just put implemented Facebook connect on my web-site using the JavaScript SDK. Now I would like to process an fql query.

So I have two questions:

1. Is it possible using only JavaScript fql as "SELECT id, name FROM user WHERE uid IN (SELECT uid1 FROM friends WHERE uid2=me())" ?

2. Because when I tried some PHP SDK code using the facebook doc

PHP:

$app_id = 'MY_ID';
$app_secret = 'MY_APP_SECRET';
$my_url = 'POST_AUTH_URL';
$code = $_REQUEST["code"];

$_REQUEST["code"] is quite normally not recognized and I don't know what is the "'POST_AUTH_URL'" because I didn't use the PHP SDK to process the Facebook-connect. Does anyone have an idea?

Answer 1

Using method: 'fql.query' is part of the deprecated REST API.

A better, future-proof way IMHO is to send your queries against the Graph API:

FB.api("/fql?q={your urlencoded query}", callback() { … } );

Answer 2

Using the JavaScript SDK you can easily execute an FQL query -

FB.api(
  {
    method: 'fql.query',
    query: 'SELECT name FROM user WHERE uid=me()'
  },
  function(response) {
    alert('Your name is ' + response[0].name);
  }
);

Don't forget to request all the permissions you need before executing any queries...

Answer 3

Sorry I can't comment yet but to clarify this helpful answer; what worked for me was formatting the FQL API call the same way I would a Graph API call with {fields: "ex1,ex2"}:

var fqlRequest = "SELECT name FROM user WHERE uid = me()";
FB.api("/fql",{q:fqlRequest}, function(response){
    // do cool stuff with response here
});

Note that I did NOT have to URL encode the string and it worked fine for me (I had used encodeURI(fqlRequest) before and it returned an unexpected % error).

Also remember to quote literals if you use them:

var id = "1234567890";
var fqlRequest = "SELECT name FROM user WHERE uid = ' " + id + " ' ";
