php array not returning on first load

Hi this is driving me nuts. I posted in another SO forum before i realised there was a Facebook specific forum, but didnt have much luck. So apologies for re-post.

I have a Facebook login script that accesses the users’ profile. it then re-directs to, and populates, a page with a register form with all of their profile information.

This code jumps through all the right hoops, but the problem is that the variable $fqlResult is not being populated the first time the page loads, and therefore the form remains blank.

If i hit f5, the page reloads, $fqlResult returns the correct data and the form is populated.

  <?php
  $is_fb = false;
  $is_linkedin = false;
  $reg_method = $_GET['conn_social'];

  if (isset($_GET['in_uid'])){
    $cur_in_uid = $_GET['in_uid'];
  }

  if ($reg_method == "facebook"){
    $is_fb = true;
  }
  else if ($reg_method == "linkedin"){
    $is_linkedin = true;
  }

  if($is_fb) {
    global $fbconfig;
    $facebook = new Facebook(array( 'appId'  => $fbconfig['appid'],
                                    'secret' => $fbconfig['secret'],
                                    'cookie' => true ));

    $user = $facebook->getUser();

    if ($user) {
      try {
        // Proceed knowing you have a logged in user who's authenticated.
        $user_profile = $facebook->api('/me');


      } catch (FacebookApiException $e) {
        error_log($e);
        $user = null;
      }
    }

    $is_fb_uid_exist = hl_check_fb_uid_exist($user_profile['id']);

    if($is_fb_uid_exist){
      $is_fb = false;
    }

    try{
      $fql = "select name, first_name, last_name, birthday_date, sex, profile_url, hometown_location, current_location, work, activities, interests, music, tv, movies, books, quotes, about_me, website, education, sports, inspirational_people, languages, pic_square from user where uid=" . $user;

      $param = array( 'method'    => 'fql.query',
                      'query'     => $fql,
                      'callback'  => '' );

      //This is returning a blank dataset on the first page load. If you refresh the page, then the array is populated.
      $fqlResult = $facebook->api($param);
    }

 }
?>

After this each field is populated with a call that looks something life this

 <?php elseif($is_fb && isset($fqlResult[0]['first_name'])) : ?>

    <input type="text" name="hl_first_name" id="hl_first_name" style="width:130px;" value="<?php echo $fqlResult[0]['first_name']; ?>" />  

Answer 1

Supply the access token in the $param, you will get the result in the first load.

 $param = array( 'method'    => 'fql.query',
                  'query'     => $fql,
                  'access_token' => ACCESS_TOKEN,
                  'callback'  => '' );
