  • Rahul Shakya

    • krizna

      in fbconfig.php ..
      $loginUrl = $facebook->getLoginUrl(array(
      ‘scope’ => ‘email’, // Permissions to request from the user
      ‘redirect_uri’ => ‘https://http://www.krizna.com/general/login-with-facebook-using-php/’ // redirect url after login

    In functions.php you have this:

    $check = mysql_query(“select * from Users where Fuid=’$fbid'”);
    $check = mysql_num_rows($check);
    if (empty($check)) {

    The variable $check make redundancy and put two records duplicated into the database, I´m fixing with this

    $check = mysql_query(“select * from Users where Fuid=’$fbid'”);
    $counter = mysql_num_rows($check);
    if ($counter > 0) {

    I´am not sure using empty function because empty return true if de the variable is declared or have the value 0

    • krizna


      $check = mysql_num_rows($check);
      //if new user.. $check will be 0 since it will not find any record and below condition will be true .. it ill insert new record ( new user )
      if (empty($check)) {

      Now check yours

      $counter = mysql_num_rows($check);
      //if new user .. $check will be 0 .. and below condition will be false .. no record inserted..
      if ($counter > 0) {

      hope this helps u

    • LM

      have to make sure your domain name and the domain in the app settings on facebook match, inclusing the subdomain or www. part(if you have qwerty.com on one and type http://www.qwerty.com in the other , it wont work) for same reason it doesn’t work on a localhost unless there is a workaround

  • Shekhar Atole

    hey admin not worked in my project?? :(

  • Agent Of Chaos

    Bro, thanks a lot for this. Very helpful. I’d like to just point out that this code is no longer working. But just add that big ass fb_ca_chain_bundle.crt file in the src folder and it works…but it’s not recognizing the username attribute anymore among the user details.

  • Eduardo Vega Torres

    Nice job. In my case, the variable $funame is not getting the username from facebook through $fbuname = $user_profile[‘username’]; The other vars are getting the right. Any guess?

  • Andy

    I cannot log out :(

    • LM

      probably same issue, if i click logout it logs me out of facebook, but i stay logged in the website using this script with full access to my fb data.(just using vanilla copy of script atm). any suggestions?

      • LM

        only way i seem to be able to revoke access to profile is to remove app in my facebook settings. bit problem, since if someone logs into my site on a PC, then logs out, someone else comes on PC – they immediately get access to previous account since logout doesn’t work and they can see all previous users fb details displayed, without even needing a fb login :/ googling fix now, but thus far seems noone else has/has noticed this issue :(… search continues…

        • Abhijith Sasikumar

          Same issue here. Fixed.

          Go to index.php page. Replace the logout link with the following link:


          go to logout.php and change the header location to your desired url.

  • Ross

    I am getting this error: You are using a display type of ‘page’ in a small browser window or popup. For a better user experience, show this dialog with our JavaScript SDK without specifying an explicit display type. The SDK will choose the best display type for each environment. Alternatively, use display type ‘popup’ if you have special requirements precluding you from using the SDK. This message is only visible to developers of your application. Has anyone else had this problem?
